Welcome to another installment of This Week in Spring, live from SpringOne2GX 2014! This year's show is something to behold! We kicked off the show yesterday with one amazing keynote here in the "lone-star state" featuring Pivotal SVP of engineering Hugh Williams, the Spring team leads Juergen Hoeller, Dave Syer, Graeme Rocher and and Netflix's Andy Glover.
We'll do some recap blogs, of course, so stay tuned. Before we get started with this week's roundup, check out this video of the SpringOne2GX 2014 logo being projected onto the Dallas Omni hotel!
And, while this is nothing like what the recording (which'll be available soon, anyway..) or even a well-written recap (stay tuned! Also coming..) would be, here are some choice tweets from last night's keynote to whet your appetite:
Indeed, even the week leading up to SpringOne2GX has been epic as the team's busily been releasing new, exciting bits for us to use! This week's roundup is packed with good stuff.
- Just in time for SpringOne2GX, Spring lead Juergen Hoeller has just announced that Spring 4.1 is now available! The new release is packed with great stuff including JMS annotations, comprehensive JCache (JSR 107) support, new Spring MVC views, websocket refinements, improved performance, and much more!
- Spring Boot co-lead Phil Webb has just announced Spring Boot 1.2.0.M1, hot on the heals of Spring Boot 1.1.6. 1.1.6 is a bug-fix that's highly recommended. 1.2.0.M1, on the other hand, is the first milestone of the very exciting 1.2 Spring Boot release. It's packed with new features: JTA support, easier consumption of JNDI-bound resources (a nice feature in its own right, but especially convenient in light JTA!), auto-configuration for the Spring Cloud PaaS connectors, easy SSL termination with Tomcat and Jetty, and improved metrics for
DataSources and health indicators.
- Spring Data lead Oliver Gierke has just announced that Spring Data Evans has gone GA! The new release is crammed full of features! Redis Sentinel, ALPS and excerpt projections, multi-store configuration, a baseline of Spring 4.0, support for
firstas keywords in derived queries, MongoDB 2.6 full text, and much more.
- Continuing the data theme, Spring for Apache Hadoop ninja Thomas Risberg has just been released. The new release adds support for append-mode store writers, kerberos configuration for secured clusters, container grouping and clustering in Spring YARN, and it remains compatible with Hadoop 2.0+, Pivotal HD 2.0, Cloudera CDH5, and Hortonworks 2.1.
- I'll be giving two webinars soon: one on building microservices with Spring on September 16th, and the other on using the Activiti workflow engine with Spring on September 23rd. Register now and bring your questions, comments and more! We'll have lots to talk about and it should be a lot of fun!
- One of my heroes, Spring Integration ninja Artem Bilan has just announced the Spring Integration Java configuration DSL milestone 3. The blog has a list of the (many) new features and supporting code. I couldn't do it justice here, just check it out.
- Spring ninja and all-around-nice guy Andy Wilkinson has just announced the release of the Spring IO platform 1.0.2 release. The new release incorporates many new projects, so be sure to check it out. The Spring IO platform is an attempt at harmonizing dependencies across the many Spring projects so that, from the perspective of the dependency consumer, there's never any conflicts with common libraries.
- Spring Integration lead Gary Russell has just announced Spring AMQP (for Java) 1.4 milestone 1. The new release includes annotation support (
@EnableRabbit) and annotation-driven message listeners (
@RabbitListener). Huzzah! This mirrors the similar support for JMS in Spring 4.1.
- Artem is not here this week at SpringOne2GX for sad, complicated reasons (we miss you Artem!), but that didn't stop him from making quite a splash this last week first with the Spring Integration Java configuration DSL release (see above) and now the Spring Integration 4.1 Milestone 1 release. The Spring Integration release includes a lot of cool features, including the migration of common types to Spring 4 itself, performance improvements, the introduction of the Spring 4.1 SpEL compiler, web socket adapters (yes, web socket adapters!), http://github.com/projectreactor, a Boon-powered JSON mapper, an implementation of the EIP splitter pattern that can return an
Iteratorfor results (and, thus, can stream them).
- Our pal Matt Raible took a look at using the Spring Boot-powered JHipster project. He hit some rough patches, but the blog provides all sorts of good information on how he got around it so that you can avoid them and really fly!
- The Blog4Java blog (run by our pal Javier Barquero) has a follow up post to his look at using Spring Batch
- And, of course, what SpringOne2GX would be complete without the annual press-release?
- There's an interesting post on the Chariot Solutions blog on converting a Spring Boot application from Java to Scala - definitely worth a look. Interestingly, it doesn't seem like you gain all that much over just using Java 8 in this particular example...
- Are you in the Dallas Fort Worth area? Since we're throwing SpringOne2GX 2014 in Dallas, we thought we'd take a moment to round up some.. ok a lot.. of the Spring team and head on over to the local Java user group (called the "Java Metroplex Users Group," or Java MUG for short) and say hi. I hope you'll consider joining us for what promises to be a really fun night!
