Welcome back to another installment of This Week in Spring. As usual, we've got a lot to cover. In particular, you'll note that this week's roundup features a lot of great Spring Batch content. So, let's get to it -- and don't forget the SpringOne2GX early bird rate ends Aug 9th!

1. I did a webinar introducing how to build REST APIs with Spring's rich REST stack a few weeks ago, and I'm happy to report that the talk - which introduces Spring MVC, Spring HATEOAS, Spring REST Shell, Spring Data REST, Spring Security OAuth and Spring Social in terms of a simple sample application that we refine - is now available on the SpringSourceDev YouTube Channel. As I mentioned last week, the slides are available on my SlideShare.net page and the code is available on my GitHub page. Enjoy, and don't hesitate to feedback/ask questions at josh(dot)long(at)SpringSource(dot)com!
2. InfoQ has a great post introducing JSR 352, the Java Batch specification. If you're a Spring Batch user, then a lot of this will look very familiar! I think this is a particularly nice JSR, and encourage you to check it out. Spring
3. Chris Schaefer has put together a brilliant Spring Batch refcard for DZone which went up yesterday, head over to DZone for the free download.
4. Craig Walls has announced that Spring Social Facebook 1.0.3 is now available. The new release addresses breaking changes in the upcoming Facebook API revision.
5. Gary Russell has announced that Spring AMQP 1.2.0 release candidate is now available. The new release features many improvements and bug fixes.
6. Johnathan Mark Smith is back at it again, with a blog on RESTTemplate To Post Data to a Web Service. Nice work Jonathan!
7. This week SpringSource is offering a four-day Groovy & Grails class in San Francisco, check it out here
8. Our pal Tobias Flohre is back with the 4th installment of his series introducing Java configuration with Spring Batch.
9. Leleu Jérôme has released a Spring Security Pac4J client. It has OAuth with providers, OpenID, CAS, and HTTP.
10. Are you a Spring Champion? Enter to win a free SpringOne2GX 2013 pass!
    
11. Vamsi Kancharla put together a nice sample project with Spring MVC, bean-validation, error handling (using @ControllerAdvice), protection against XSS and input form attacks, and a lot more. Check it out!
12. Kim Saabye Pedersen put together a nice post reinforcing some useful (and hopefully well-understood!) principles of singletons in Spring.
13. Hantsy Bai has put together a very nice post explaining how to create a Spring project from the Spring Tool Suite.

Welcome back to another installation of This Week in Spring! What a week! We're fast approaching the final stretch of the journey to SpringOne2GX 2013 and preparations are underway at full tilt. This year's going to be memorable. I wish I could tell you more, but trust me when I say you need to be at this show this year! :)

Anyway, let's get on with the roundup!

1. Mark Pollack has announced the release of Spring XD 1.0 milestone 1. Spring XD is a unified, distributed, and extensible system for data ingestion, real time analytics, batch processing, and data export. The project’s goal is to simplify the development of big data applications.
2. Join Tony Erksine from Liberty University on June 27th as he instructs us How to talk Spring and Influence People, a pragmatic lesson on soft skills and technology adoption strategies needed to help get other people in your company excited about and using, new technology -- in this case, with Spring.
3. Want a pass to SpringOne 2GX 2013? If you're a Spring champion, show off your stuff on our champions forum and follow these instructions by June 21, 2013. You might be one of our 5 lucky winners! (If you're a Groovy & Grails or Cloud Foundry champion, never fear, we will be rolling out future contests for you!)
4. Head over to gopivotal.com for the next blog in the Hadoop 101 series -- How to Use Spring Batch with Spring for Apache Hadoop.
5. We're excited to launch A Week of Spring in conjunction with Manning Publications. Check out this post for more information on great discounts for titles covering SpringSource technologies! Every day we're posting a new 50% discount code for two books.
6. Our pal Tobias Fiohre is back at it again, this time with not one, not two, but three posts on Java configuration support for Spring Batch, just released in the latest Spring Batch 2.2.0.RELEASE of Spring Batch. The first post looks at how Spring Batch's Java configuration support compares with the XML equivalents. The second post looks at the Spring Batch StepScope, which lets you configure jobs with parameters provided at runtime (as opposed to design-time. The third post looks at how to use the new configuration style with Spring's environment profiles feature.
   
7. Johnathan Mark Smith has put together a post on how use Spring MVC and Spring MVC Test
   
8. Xavier Padró's has put together a nice post that introduces Spring's core Aspect-Oriented Programming support.
   
9. The video replay of the webinar from the Broadleaf Commerce project on their migration from GWT to Spring MVC is now online at our SpringSourceDev YouTube channel.
10. This isn't strictly Spring-related, but I felt it worth mentioning: Java 9 is slated to drop support for compiling Java 1.4-or-older source code. Java 8 is approaching (finally!), and Spring 4 will offer first class support for Java 8 lambas. Java 6 is EOL as of February 2013, so if you're not already on Java 7, consider just making the jump to Java 8 when it drops early next year. If you're migrating right now, definitely consider looking at Java 7 at a minimum. Spring, of course, works well with older JDK versions, but we often provide functionality specific to newer language releases if they're available. For example, we debuted annotations (like @Transactional) when Java 5 made it feasible, as an addition to our then primary support for commons annotations, even while we supported Java 1.3 and 1.4. Java 8 is no different.
11. I did a webinar last week on building REST APIs with Spring. The webinar video will be up soon on our SpringSource Developer YouTube channel. For the many who've asked, the code is available on my GitHub account, and the slides are available on my SlideShare account. Check them out!
    
12. Petri Kainulainen has put together a really detailed, easily-read post on how to plugin a property from a property file when configuring the @Scheduled annotation's CRON expression
    

Hey guys, welcome to another installment of This Week in Spring! This week I'm in New York City, New York, talking to developers at the NYC Java Meetup and at ScalaDays about Spring. We've got a lot of webinars this month, so be sure to check out the details below!

1. Want a pass to SpringOne 2GX 2013? If you're a Spring champion, show off your stuff on our champions forum and follow these instructions by June 21, 2013. You might be one of our 5 lucky winners! (If you're a Groovy & Grails or Cloud Foundry champion, never fear, we will be rolling out future contests for you!)
2. Oliver Gierke has announced Spring Data Babbage, the first milestone of the next Spring Data release train. This release includes a lot of new features, so be sure to check out the release note!
3. Spring Batch 2.2.0 is now available! This is a major release that supports Spring Data, Java Configuration, AMQP, and SQLFire in addition to a number of other features. Spring Batch and our participation in the expert group has heavily informed the JSR-352 specification that recently has been finalized.
4. Spring Tool Suite and Groovy / Grails Toool Suite 3.3.0 M2 has been released, based on Eclipse Kepler 4.3. This milestone release improves Java Configuration support and is Spring Framework 4 ready.
5. Craig Walls has announced that Spring Social Twitter 1.0.5 and Spring Social 1.0.3 have been released! The new release fixes a few bugs and is being made available in anticipation of the deprecation of the 1.0 version of the Twitter API.
6. Gary Russell has also announced the Spring Integration 2.2.4 and 2.1.6 maintenance releases, to incorporate the Spring Social Twitter updates mentioned above.
7. I'll be doing a webinar on Thursday on RESTful service design with Spring. As usual, there will be two sessions - one at 3PM GMT and one at 10:00AM PST - to accommodate as many timezones as possible. The webinar will introduce Spring's stack for building RESTful services. We'll start with a simple API, then advance the API, introducing Hypermedia controls with Spring HATEOAS, introducing conventions-oriented repository-based APIs with Spring Data REST, security with Spring Security OAuth and Spring Social and addressing common cases like file uploads, exception handling, record paging, and Ajax. I look forward to seeing you there!
8. Don't miss Jon Brisbin on June 18th, 2013 as he introduces Introducing Reactor - A framework for asynchronous applications on the JVM. Reactor provides a foundational framework for applications that need high throughput when performing reasonably small chunks of stateless, asynchronous processing.
9. Join Tony Erksine from Liberty University on June 27th as he instructs us How to talk Spring and Influence People, a pragmatic lesson on soft skills and technology adoption strategies needed to help get other developers in your company excited about,a nd using, new technology -- in this case, with Spring.
10. I gave a talk on the latest at the amazing DevNexus conference in March on Spring 3.1, 3.2, and 4.0 in March, and that talk is now available online on InfoQ. Do check out the talk, but also be sure to check out the more up-to-date version of that deck from my talk at JAXConf available on my SlideShare account.
11. Head over to the Pivotal Blog for a short primer on Hadoop programming, which walks you through a simple word count program. The example looks at the canonical word-count problem and then looks at other solutions in the ecosystem like Pig, Hive and Cascading. The next blog in the series will introduce Spring for Apache Hadoop for a beginning audience, providing a unified, consistent alternative to the four different methods discussed in this blog post.
12. In related news, if you're in the New York City area, join me Wednesday evening where I'm giving the same talk at the 10gen offices for the NYCJava meetup. Thanks again go to 10gen, the company behind MongoDB, for hosting the meetup.
13. The JavaBeat blog has a nice post on how to use Spring's robust multipart file upload support. Spring's support abstracts away common APIs for file uploads - including the commons-fileupload API and the Servlet 3 API - and lets you use those APIs for HTTP miltipart-encoded file uploads, typically in web applications or REST services. Definitely worth a read, check it out!
14. Idan Fridman put together a rundown on some of the common types of components in Spring Integration, including splitters, transformers, aggregators, and more.
15. For those of you who are looking to take your Spring skills to a new level of expertise, SpringSource has just released the Professional Spring Training Schedule for July 2013
16. The Spring tutorials blog has a great post introduce Spring's @Async and @Scheduled annotations.

We are pleased to announce that Spring Batch 2.2.0.RELEASE is now available via Maven Central, Github and the SpringSource download repository.

Support for Spring Data

Spring Data is a collection of projects intended to make it easier to develop Spring-powered applications that use new data access technologies such as non-relational (NoSQL) databases. Based on a model of exposing Repository objects, Spring Data allows applications to access data in a simple and consistent way across many new platforms. Spring Batch 2.2.0.RELEASE provides ItemReader implementations for Neo4J and MongoDB as well as ItemWriter impelementaions for Neo4J, MongoDB and Gemfire. We also have created a RepositoryItemReader and RepositoryItemWriter…

Welcome to another installment of This Week in Spring. The SpringOne2GX super early bird registration discount expires on June 10th, 2013, so make your arrangements now to secure the discount. Also, we've got three webinars coming up this month, check out the details below. As usual, we've got a lot to cover, so let's get to it!

1. I'll be doing a webinar on building effective REST APIs with Spring on June 13th. I'll be introducing Spring's deep support for REST services, starting with Spring MVC and moving up the Richardson Maturity Model to incorporate Spring HATEOAS and, ultimately, Spring Data REST. Along the way we'll look at the REST shell, and other concerns like security through OAuth.
2. Join Jon Brisbin as he introduces Reactor in a webinar on June 18th. Reactor provides a foundational framework for applications that need high throughput when performing reasonably small chunks of stateless, asynchronous processing.
3. Join Tony Erksine from Liberty University on June 27th as he instructs us How to talk Spring and Influence People, a pragmatic lesson on soft skills and technology adoption strategies needed to help get other developers in your company excited about,a nd using, new technology -- in this case, with Spring.
4. If you're in the bay area, be sure to check out JAXConf happening right now in Santa Clara. Admission is free and there are some great speakers there. I will be speaking there tomorrow on Spring 4, and Multi Client Development with Spring, so feel free to drop by if you'd like to talk Spring, Cloud Foundry and big-data.
5. You probably saw Paul Chapman's awesome posts introducing Spring MVC's support for content negotiation last month and this month he's back with a post on content negotiation using Spring MVC views. Be sure to check both of them out, as they provide solid foundations for dealing with content negotiation in the ever increasing paradigm of REST.
6. Our friend Petri Kainulainen continues his look at Spring Data SOLR and explains how to add custom repository methods to the implementations above and beyond what Spring Data already provides out of the box. This example is in the context of Spring Data SOLR but the approach is generic and works for all the repository implementations.
7. RabbitMQ ninja Alvaro Videla has done an amazing job introducing RabbitMQ's power in the latest edition of Developer Magazine.
   
8. Every now and then I run into old but cool content, like this project demonstrating how to build a Spring MVC application with Scala. As you might imagine, there's not much difference between Scala and Java, but this is nonetheless an interesting example. Check it out.
9. I've been knee deep in REST, in preparation for my upcoming webinar, and I stumbled upon a great, albeit older, post by Apache Shiro PMC member and REST-ninja Lez Hazelwood on providing good client feedback on errors with REST in Spring MVC.
10. Spring HATEOAS lead and Spring Data ninja Oliver Gierke did an amazing talk introducing Spring HATEOAS at Oredev last year and it's available online. Definitely be sure to check it out!
11. Our pal Nicolas Fränkel is back, this time with a short rant on how to approach modularity in Spring configuration.
    
12. JavaBeat has a nice post on how to handle themes in Spring MVC.
13. The BitwiseOR blog has a nice post on how to setup a simple, working Spring MVC application.
14. Alexey Zvolinskiy put together a nice, complete-with-code, post on how to use Spring Data JPA to build an application.
15. David, from The small world for Yiyi blog, has put together a nice post on using PDF, XML and JSON from Spring MVC.
16. Our pal Johnathan Mark Smith is back, this time with another video introducing how to use Spring's Java configuration

Welcome to another installment of This Week in Spring. In case you missed it last week, the vast majorty of the SpringOne2GX 2013 agenda has been published, so book now and get the early bird rate on the conference, and airfare! As usual, we've got a lot to cover this week, so let's get to it!

1. Spring Batch lead Michael Minella announced Spring Batch 2.2.0 RC2. The new release is chalk full of great new features including support for the Spring Batch Java configuration API and a Spring Data GemFire ItemReader and ItemWriter.
2. Gary Russell just announced Spring Integration 3.0 milestone 2. Be sure to check out the new features and kick the tires!
3. Join me for a webinar on Building REST-ful Services with Spring - June 13th, 2013. I'll discuss OAUTH, Spring MVC and Spring HATEOAS as it relates to REST.
4. Rossen Stoyanchev's blogged about the upcoming support for WebSockets in Spring 4 and it looks very compelling!
5. Gary Russell also just announced the Spring Integration MQTT extension adapter, milestone 1, that makes it easy to work with MQTT - a messaging technology that lends itself to lightweight messaging - from Spring Integration.
6. Oliver Gierke has written up a great response to the question, how do I return a Spring Data page as JSON on Stack Overflow.
7. Long-time readers of this roundup will know about Thymeleaf, the templating engine that breathes new life into your web application view templates and that works really well with Spring. The first, stable 2.0.0 version of Thymeleaf-testing has just been released.
8. Joris Kuipers, on the Trifork blog, has announced a new set of macros for doing form inputs with Spring applications using Freemarker, an alternative - and very powerful - templating engine.
9. Oleg Tsal-Tsalko put together a talk on the new bits in Spring 4. Nicely done, Oleg!
10. Johnathan Mark Smith is back at it again, this time with a video on how to do Java configuration with Spring. Check it out!
11. Maciej Walkowiak put together a great post on how to audit entities using Spring Data MongoDB.
12. The poorly-named Java2J2EE blog has a great, short-and-sweet post on how to setup JPA and Spring MVC with Spring's Java configuration style. I would however discourage users from calling the lifecycle methods on a Spring FactoryBean directly, and instead choose to dereference the configured result:

    @Bean public EntityManagerFactory emf(){
       LocalContainerEntityManagerFactoryBean lcemfb = ..
       return lcemfb;
    } 
    
    @Bean public PlatformTransactionManager transactionManager(){
      EntityManagerFactory emf = emf().getObject();
      return new JpaTransactionManager( emf );
    } 
    
    

This Week in Spring

Welcome to another installment of This Week in Spring! We are finally running out of SpringOne2GX video recordings.. this is the last week in Spring that you'll see them, so refer back to the replays page for an index. As usual, we've got a lot to cover so let's get to it!

1. Spring lead Juergen Hoeller just announced the release of Spring Framework 4.0 M1 and 3.2.3.RELEASE The 3.2.3 update mainly includes updates and fixes related to Java 8 support. The 4.0 milestone, on the other hand, is a look ahead to the many awesome features in Spring 4.0 including support for web sockets, Java EE 7, the @Conditional annotation (in the same vein as the @Profile annotation) and much more, so be sure to check it out!
2. TcServer 2.9.2 is now available! The release contains security fixes and updates, for more details check out the release notes.
3. Jennifer Hickey's talk -- Thinking outside the container - Standalone Applications on CloudFoundry has been released in HD on YouTube.

7. Xavier Padró has put together a nice post on how to communicate within a Spring Web Flow flow
8. Static.com has announced their Hadoop and Cloud Foundry-powered service. Frankly, it looks really cool and cost-effective as a public platform on which to host applications that need a backoffice Hadoop solution.
9. I can't believe I missed this! RabbitMQ 3.1.0 is out (slightly old news) and, to introduce it, you should check out this amazing RabbitMQ 3.1.0 in pictures.
10. The HMKCode blog has a nice post on doing the not-so-well-documented, but common, things with a MyBatis, Spring and jUnit integration.
11. The Java Code Geeks have put together a nice tutorial on how to process radio buttons in a form in Spring MVC.
    
12. Gerry Tan has put together a nice blog on how to bind form date values with Spring MVC.

Welcome to another installment of This Week in Spring! Some rather exciting projects have been announced this week, and if you can believe it, we're almost out of SpringOne 2012 replay content! Good thing the SpringOne 2013 agenda grid is going live very soon, so we'll be able to look ahead. As usual, we've got a lot to cover so let's get to it!

In preparation for the agenda grid going live, a lot of new SpringOne 2013 sessions have been accepted:

• Getting Started with Spring Security 3.2 (Rob Winch)
• Performance-tuning the Spring Petclinic sample application (Julien Dubois - Ippon Technologies)
• Spring with Immutability (Matt Stine)
• Going Beyond Dependency Injection (Mark Secrist)
• Tooling for Spring's next generation (Martin Lippert, Andy Clement)
• Futures and Rx Observables: powerful abstractions for consuming web services asynchronously (Chris Richardson)
• Making Connections with Spring Social (Craig Walls)
• Troubleshooting Live Java Web Applications (Ashley Puls - New Relic)
• Spring and Sencha - A Match Made In Heaven, or at least the Cloud - (Jay Marshall + TBA, Sencha)

1. Jon Brisbin announced the Reactor project. The Reactor project aims to provide a solid foundation for asynchronous IO-based applications, on top of which it is natural to provide integrations for technologies like Grails and Spring. Reactor already features a good multi-language story with support for Groovy and Java (and, particularly, the upcoming Java 8 release!) Be sure to check this out, especially the comments section if you have questions about how this compares to other asynch technology!
2. Spring Security lead Rob Winch has been busily enhancing the Spring Security and Spring Security OAuth Java Configuration story. He's got a first cut of the Spring Security OAuth Java Configuration API available, and I'm sure he'd appreciate any feedback on the new DSL, so definitely be sure to check it out! Nice work, Rob!
3. Webinar on Thursday May 16th with Chris Richardson, author of POJOs in Action, on Decomposing Application for Deployability and Scalabilty. Register Now!
• This is an essential talk to understanding the new application architectures discussed in the SpringOne 2012 keynote - how to break down large applications into small, scalable, discrete services. It's tough not to use NetFlix's Asgard as a great example of this done well, an example that many of you may recognize.
4. Join Broadleaf Commerce's Andre Azzolini for a Webinar on Tuesday, May 28th as they discuss their Lessons Learned Moving from GWT to SpringMVC.
5. Paul Chapman introduces some of the diverse support for content negotiation in Spring MVC on the SpringSource blog.
6. Chris Harris's talk, the Spring Data MongoDB Project, from SpringOne2GX 2012 is now available in HD on YouTube!
7. Lee Faus's talk, Extreme Makeover - Application Edition, from SpringOne2GX 2012 is now available HD on YouTube!
8. The JIWHIZ blog, and blogger Yuan Ji, has put together a nice post introducing Spring's Java configuration support.
9. This post - from blogger Chris Wong in a January post called "JmsTemplate is not evil" - explains some of the subtleties of using Spring's CachingConnectionFactory with a raw ConnectionFactory and then, for extra points, introduces one approach to dramatically speeding up ActiveMQ, in particular.
   
10. The HMKcode blog has a nice, exhaustive post introducing how to use the jQuery-file-upload plugin with Spring MVC.
11. Have you taken a look at HATEOAS yet? HATEOAS is a design pattern, an approach, for building better RESTful web services. Spring HATEOAS makes doing so dead simple atop Spring MVC, and this blog by Geraint Jones introduces Spring HATEAOS very nicely
12. Blogger Alexey Zvolinskiy answers a common question: how do I bind checkboxes to the model object that's sent back and forth to the server in Spring MVC?
13. Our friend @baeldung maintains a daily Twitter feed of awesome posts about Spring on StackOverflow, and I think he's dug up some absolutely amazing content. One post answers a question I am frequently asked: how do I enumerate all the Spring MVC @Controller-annotated beans at runtime?
14. Another great post that I found while trawling through the @SpringAtSO handle was this post, explaining how to propagate request-scoped attributes beyond the thread of the current request. This post applies generally to any situation where a request-scoped attribute needs to propagate beyond its original thread and request.

1. Juergen Hoeller and Marius Bogoevici's talk, Java EE services for Spring applications, from SpringOne2GX 2012 is now available in HD on YouTube!
2. John Davies's talk, Spring Integration in the Wild, from SpringOne2GX 2012 is now available HD on YouTube!
3. Kim Saabye Pedersen has written a small example on using @Transactional on an interface with Spring's transaction management infrastructure. Nice job, Kim!
4. Would it be possible to take Spring Petclinic as it is now and scale it up to 1000 requests per second on a single server instance? Julien Dubois from Ippon Technologies has written a great series of five blog entries on that topic. If you missed them from the previous roundups, check out the whole series, starting here!
5. Petri Kainulainen has written a great post introducing how to sort data using Spring Data SOLR.
6. By the by, I know I've mentioned this before, but it really is handy. Have you checked out Alvaro Videla's RabbitMQ simulator?
7. Spring Data ninja Oliver Gierke has written a great response to the question, How do I use Spring Data MongoDB in a multi-tenant fashion? Be sure to check it out. Generally, his advice is applicable to many such scenarios.
8. Serkan ÖZAL has put together an awesome, bytecode-based RowMapper that can be used with Spring's JDBC infrastructure (like JdbcTemplate) and that can handle relationships like an ORM might. Because it's bytecode-based, it's very fast and not given to the same reflection-based performance limitations of Spring's own BeanPropertyRowMapper. I haven't tried this out yet, but it looks very promising!
9. Our friend Roger Hughes is back with a tutorial (of two posts, thus far). The first, RESTful Ajax with Spring MVC, establishes an application (without REST and Ajax) and the second then introduces serializing data objects using Jackson, a JSON serializer.
10. Bharat Sharma also wrote a nice post on serializing to JSON with Spring MVC this week!
11. Blogger Kal wrote up a nice post on how Spring MVC simplifies file-uploads with Spring MVC and commons-fileupload.

Welcome to another installment of This Week in Spring! We've got a lot to cover this week, as usual, so let's get to it. Did you miss last week's Pivotal public launch? Catch the replay and learn about GE's investment in the new entity! Pivotal's mission is about bringing consumer-grade software to the enterprise -- where open source technology like Spring, Groovy, Grails, RabbitMQ, Redis, and Cloud Foundry, are already widely adopted. Check out the new Pivotal website, under the Community link (top right) for some other open source initiatives that might surprise you!

1. Oliver Gierke has announced Spring HATEOAS 0.5, which contains lots of new features!
   
2. Spring Security lead Rob Winch has announced that Spring Security 3.1.4 is now available. This is a maintenance release with a number of bug fixes including OSGi support for Spring 3.2.
3. Spring Data ninja Oliver Gierke also (boy that guy gets around!) tweeted a look at the Spring Data roadmap: introducing Spring Data "Babbage."
4. Spring Data Arora SR1 released this week (named for Sanjeev Arora). As an aside, you have probably noticed that the names of the various Spring Data release trains are adapted from various influential names in computer science. The new release is named for Charles Babbage.
5. Adam Shook and Dr. Mark Pollack's webinar, Hadoop, Pivotal HD and Spring for Apache Hadoop, is now available online.
6. Gil Tene, of Azul Systems, gave an amazing talk at SpringOne2GX 2012 called Understanding Java Garbage Collection and what you can do about it, which is now online.
7. New SpringOne2GX replays now available in HD on YouTube: Building for Performance with Spring Integration & Spring Batch, Case Study: Provisioning a Multi-Site In-Memory Database
8. James Watters shared a video he'd discovered on setting up Cloud Foundry and BOSH. It's pretty epic and worth a watch if you want to get a handle on BOSH.
9. What people write blog posts about sometimes surprises me. The Javarevisted blog has a nice post introducing Spring's (fairly internal, albeit stable) org.springframework.util.StringUtils class, with examples on how to convert collections to delimited strings. I think this is perhaps too much information on the subject, but I love the enthusiasm!
10. RabbitMQ developer-advocate Alvaro Videla has put together a post on how to unit-test RabbitMQ from PHPUnit. This approach is pretty cool, though I wonder how well it would play in Java and jUnit with concurrent test suite execution. Either way, this is a nice way to unit test my favorite message queue!
11. Do you need a Spring Integration adapter? Have you checked out the Spring Integration extensions repository? This repository simply collects adapters that move faster than the Spring Integration core, or that are still being polished. It's a great place to find solutions to various problems. Heck, even the pull requests are chock full of useful stuff - I see an MQTT adapter in there by the amazing Gary Russell!
12. Check out this amazing post on @gopivotal blog called 800,000 Messages/Minute: How Nokia’s HERE Uses #RabbitMQ to Make Real-time Traffic Maps over on the @gopivotal blog. It introduces the Nokia HERE architecture that builds on Spring AMQP and RabbitMQ.
