Welcome back to another installment of This Week in Spring. For those of us in the US, the Thanksgiving holiday is upon us. Generally, the idea behind Thanksgiving (which has analogs in many other countries, as well) is to have a day to reflect on the things we are thankful for. In that spirit, let me offer one of the things that I am thankful for: thank you, dear readers, for being part of the most awesome
community out there.
Between all the cool stuff you guys are doing and all the cool stuff happening at SpringSource,
it is an absolute pleasure to put together this roundup every week. We…
As usual, visit the community download page to get the latest bits.
Spring Integration 2.1 M2 Has Been Released. It includes numerous fixes and new features, including a refactored (simpler and more flexible) aggregator and resequencer,
an XPath filter,
JDBC stored procedure adapters, and
AMQP-backed Message Channels. Be sure to get the bits from the community download page. Readers of this column will remember that InfoQ recorded sessions from the Paris "What's Next," and we got to see Adrian Colyer's keynote on cloud computing in the enterprise. InfoQ's just released two more…
Spring Social got some great coverage elsewhere, too, including this post from adtmag.com on the new 1.0 release.
If that wasn't enough, there's also service-layer support (e.g, you can generate service objects), choice in which type of repository layer is generated (active-record style or traditional repository objects), much improved, very flexible GWT support, MongoDB support, and multi-schema aware database reverse engineering (DBRE) and shell improvements.
Honestly, this little paragraph doesn't do it justice. Check out the blog for the skinny.
To learn more about the Micro Cloud Foundry, check out these three blog posts introducing Micro Cloud Foundry to Spring developers and Grails developers, and introducing the support for Micro CloudFoundry in SpringSource Tool Suite. In this latest post, he cautions that while using the conventions in some cases can be very helpful (such as with ), using some defaults can cause confusion. This is a fair point, and it's nice to have the choice, either way.
Nice work, Roger!
This blog post highlights the fact that Spring.NET supports bi-direction injection, a feature…
That said, this post is a very good read.
TomcatExpert.com comments on the support for explicit release of JNDI resources in Apache Tomcat.
Apache Tomcat 7 contains a number of new features around database connection pooling, which help administrators keep their application available and serving content, collecting customer information, and supporting their applications. The main one that has garnered a lot of attention is the new JDBC Connection Pool feature introduced by Filip Hanik last year. Another connection pool attribute not yet discussed here on TomcatExpert.com is the new…
Today VMware team released Micro Cloud Foundry, a complete, local version of the popular, open source Platform as a Service that lets developers run a full featured cloud on their Mac or PC. Using Micro Cloud Foundry developers can build end-to-end cloud applications locally, without the hassles of configuring middleware while preserving the choice of where to deploy and the ability to scale their applications without changing a line of code. Micro Cloud Foundry supports Spring and Java, of course, but also provides runtime environments for Scala, Node.js, and Ruby so that you can release your…
Spring has rich support for transaction management through its PlatformTransactionManager interface and the hierarchy of implementations. Spring's transaction support provides a consistent interface for the transactional semantics of numerous APIs. Broadly, transactions can be split into two categories: local transactions and global transactions. Local transactions are those that affect only one transaction resource. Most often, these resources have their own transactional APIs, even if the notion of a transaction is not explicitly surfaced. Often it's surfaced as the concept of a session, a…
and a FactoryBean whose definition is thus:
