The Spring team is gearing up for a major rev of Spring Batch - Spring Batch 3.0.0 RC1 which introduces JSR-352 support, among other features. Adopting a Java EE standard that was directly based on Spring Batch to begin with is fortunately, fairly straightforward for us. JavaEE7 compliance updates and expands the scope of Spring Batch 3.0.0 to combine JavaEE7/352 compliance with years of Batch's battle-tested, proven-in-production codebase. Of course, there is a wealth of capability and features that go far beyond the specification into distributed processing and beyond. In this webinar, project lead Michael Minella will cover Spring Batch's implementation of JSR-352 as well as some of the new features in the 3.0 release.

With the increase in the number of devices that emit information it has become ever more important to be able to retrieve this data and process accordingly. In response to this need, MQTT has become the defacto lightweight transport for connecting an "Internet of things". With that being said, how do your applications support for eventing, messaging, and scheduling? Utilizing Spring Boot and Spring Integration you will see how to create an application with a scheduler that will retrieve data from a web service, cleanse and emit the data via MQTT. Then we'll show you how to create an application also written using Spring Boot and Spring Integration, that will capture the MQTT events and record the results. From this discussion you can see how to use these tools and take advantage of them for your own big data projects as soon as you return to the office.

In my previous blog we demonstrated how the new Spring Security testing support can ease testing method based security. In this blog we will explore how we can use the testing support with Spring MVC Test.

Setting Up MockMvc and Spring Security

In order to use Spring Security with Spring MVC Test it is necessary to add the Spring Security FilterChainProxy as a Filter. For example:

@RunWith(SpringJUnit…

In my previous blog we explored how we can use the testing support with Spring MVC Test. We will now see how the same support works with Spring Test MVC HtmlUnit.

[callout title=Minimum Versions]The Spring Security testing support does not work with spring-test-mvc-htmlunit-1.0.0.M1.jar. Instead, you just use the latest snapshot. This is due to some slight modifications to allow Spring Security and the…

I'm pleased to announce that Spring Web Services 2.2.0.RELEASE has been released! This is the first release in the 2.2 release cycle. The main new feature in 2.2 is the introduction of code configuration support for Spring-WS. This means that you can now configure Spring-WS with a simple @EnableWs annotation. For instance:

@Configuration
@EnableWs
@ComponentScan(basePackageClasses = { MyConfiguration.class })
public class MyWsConfiguration {

  // @Beans go here
}

For more information about this topic, refer to the javadoc of @EnableWs. You can also read more about this new feature in the updated reference documentation. To view a complete list of changes see the changelog…

This is the first maintenance release of Spring Integration 4.0; it contains a small number of fixes and improvements, and brings the dependencies for other Spring projects up to their latest versions.

See the release notes for details of the contents.

See the Project Home Page for documentation, downloads etc.

We've just announced the availability of the GA release of the Spring Data release train named Dijkstra. I'd like to use this chance to walk you through some of the features we added in this release.

5 new modules joining the train

The first big feature the release includes is the addition of 5 modules to the release train. Most of them have been around for quite a while but going forward we'll release them in sync with the other modules. The newly added modules are Spring Data Elasticsearch, Cassandra, Couchbase, Gemfire and Redis.

Spring Data Commons

A lot of the improvements of a release…

Welcome back to another installment of This Week in Spring! This week I'm in Krakow, Poland for Geecon, the Polish developer conference where, of course, I'll be speaking to developers about Spring. (and, maybe, Spring). If you're around, find me, I'll be wearing the giant Spring leaf t-shirt! :)

Other than that, there's a lot to get through so let's get to it!

• In preparation for the upcoming Spring IO Platform, Spring Data release train Dijkstra has been released! This is a tremendous release train that includes: JPA, MongoDB, Neo4J, Apache Solr, Couchbase, Cassandra, Elasticsearch, Gemfire, Redis and Data REST! Congrats to the Spring Data Team!
• Spring Boot 1.1.0 M1 is now available and introduces MongoDB and Gemfire support, as well as improved actuator metrics and health endpoints.
• Final maintenance releases for the Spring Framework 3.2.x and 4.0.x versions are now available!
• Spring Integration ninja (rockstar!) Artem Bilan put together a nice post introducing all the amazing Java configuration support in the nascent Spring Integration Java configuration DSL, which builds upon the basic @EnableIntegration support available in the just-released Spring Integration 4.0. You should read that post. Seriously. I want to steal some of Artem's thunder by excerpting this one amazing code-snippet:

  java @Bean IntegrationFlow helloWorldFlow() { return IntegrationFlows.from("helloWorldInput") .filter("World"::equals) .transform("Hello "::concat) .handle(System.out::println) .get(); } Yep! That's a Spring Integration flow that handles input messages, filters them, transforms them, and then gives them to the escape-hatch method, handle, which lets the developer insert any behavior into the mix. Remember, you can change anything about this - including where it gets the messages from and where it writes the messages to. Indeed, the output of one flow could be the input to another. Congratulations, Spring Integration team! Also, make sure to check out the launch webinar replay!

• I know I mentioned this last week, but it's so worth a re-read! Groovy 2.3.0 is here! (Hah! Gotcha! This week's link was to a different post by the same author on the subject of the Groovy 2.3.0 release! But aren't you glad you read it, anyway?) Go, Groovy, go!
• My pal Pieter Humphrey has done a nice introductory screencast on Spring XD - showing how to get up and running doing stream processing, and wiring it to an analytics dashboard in less than 7 minutes. XD uses a deceptively simple DSL (domain specific language) and no Java code - it's never been easier to work with Hadoop.
• Spring Security lead Rob Winch has been moving heaven and earth to make unit-testing secure applications easier than ever. In this first installment of a new series, Rob looks at new annotations designed to stand in place of a live-fire Spring Security apparatus to mock a Principal, a UserDetailsService, and more. Check it out and stay tuned for more!
• Speaking of Rob Winch, he gave an epic introduction to Spring Security at SpringOne2GX 2013 last year. This is a perfect place to jump onboard if you're new to Spring Security.
• New Relic's Ashley Puls was kind enough to do a webinar with your humble author on Web Application Diagnostics using New Relic. Thanks, Ashley! I'll be very honest, this webinar was super informative for me. I knew just a little about New Relic, and in working through the development of the webinar I learned about a zillion and five use cases that are well served by New Relic. Really cool stuff!
• Also published this week - a SpringOne2GX 2013 Replay by Emad Benjamin and Guillermo Tantucho: Virtualizing and Tuning Large Scale Java Platforms. This goes over JVM memory tuning and all the tricks and tips for getting Java to run well on a virtualized environment.
• SpringOne2GX 2013 replay - a great talk from SAS Software: Migrating from WebLogic, WebSphere, JBoss to Pivotal tcServer. This might go well with a recent post on why App Servers are dead by Eberhard Wolff.
• Do you love Spring's new home on the web, spring.io, as much as I do? Want to learn more? Check out this talk by project lead and Spring ninja Chris Beams on the makeup of the site, its development, and deployment.
• Last week, Spring Data Neo4j lead and graph-ninja Michael Hunger and I gave a talk on Spring Boot and Neo4j. This talk was fun for me because it gave me a lot of excuses to play with Neo4j. In point of fact, Michael and I are doing a webinar on about the same subject on the 20th of May (that's 7 days away!), so come see what we've come up with. In the meantime, you may want to check out this recent post on creating a time-tree with Cypher, the language that Michael works on that's used to drive interactions with Neo4j. That post was, of course, a response to another post that Michael put together on importing forests into Neo4j, also worth a read!
• I quite liked this post introducing how to setup a Spring Batch job using Spring Boot. The author found a comfortable configuration-middle ground in the Groovy BeanBuilder support, and describes it nicely in this post
• Moritz Schulze has put together a very nice post, following others in the series, on how to integration test REST services
• Are you using Spring Boot and want to use Spock? Netflix engineer Tomas Lin has put together an example on his GitHug page. Check it out!
• Jakub Kubrynski has put together a nice post on how to use Spring Boot's org.springframework.boot.actuate.system.ApplicationPidListener (which Jakub contributed - thanks Jakub!) - to work with the application's process identifier (PID). Nice!
• Meltdown 1.0.0 has been released! Meltdown is a Clojure interface to the Reactor project. So... functional programming and stream processing inside a lisp-like language? A dream! Check it out!

Today we are pleased to announce the release of Grails 2.4. This is the final release in the 2.x line of releases and includes a number of significant updates.

Most importantly Grails 2.4.x ships with key pieces of the Spring IO platform, including Groovy 2.3 and Spring 4.0.5.

Release Highlights

In addition to the inclusion of the latest versions of Spring and Groovy there are a number of key new features in this release, including:

• Standalone GORM & GSP - Yes, GORM for Hibernate 4 and GORM for MongoDB can both be used outside of Grails in a Spring Boot application or Groovy script.
• Static Compilation - Using extensions to Groovy's static compilation features, it is now possible to statically compile many interactions with the Grails framework, including dynamic finders.
• Asset Pipeline Plugin - Grails 2.4 replaces the previous Resources plugin with the new Asset Pipeline plugin for managing static assets (CSS, JavaScript etc.).
• GORM Subqueries - GORM has been enhanced, with extensive support for correlated subqueries.
• New Maven Plugin - The Maven plugin…
