Welcome to another installment of This Week in Spring! I'm in Malmo, Sweden at the fantastic Øredev conference, talking to developers about Spring, Cloud Foundry, and more! I'll be at JMaghreb next week and then at Devoxx 2013 where I'll be talking to developers about Spring, Cloud Foundry, RabbitMQ and more along with my pals Dr. Dave Syer, Alvaro Videla, and Andy Piper. Looking forward to seeing you at any of these places! Ping me on Twitter (@starbuxman) if you want to talk Spring, the cloud, big data and anyting else!

With that, we've got a lot of really great stuff this week so let's get to it!

1. First, the big news: Spring Framework 4.0 RC1 has been released! The new release includes full compatability with OpenJDK 8 developer previews, Groovy configured beans, improvements to Spring MVC, smarter proxies, time zone resolution (connected to JSR 310 and Joda-Time), Spring HATEOAS-inspired link-building, improved websocket support, and a lot more! Get the bits, test your apps, and be sure to let us know how you like it!
2. Spring Security lead Rob Winch is at it again, this time with a Spring Security 3.2.0 RC2 release which includes resolutions for 80+ issues, and a slew of upates - some breaking, so to be sure to update and verify everything.
3. Additionally, Rob's just released Spring LDAP 2.0.0.M1, which adds a lot of new functionality including Spring Data repository and QueryDSL support, a fluent LDAP query builder, a custom XML namespace for LDAP, Java 5 featues, and some restructuring
4. P.S.: If you happen to be in the London area or with easy access to it, check out the Spring eXchange: a packed two-day show on Nov 14/15, with key Spring engineers presenting the latest and greatest - of course including Spring Framework 4.0!
5. I gave a talk at JavaOne called the Spring Update that looks at a lot of the cool new things coming out of the Spring division at Pivotal. The talk is now online at Parleys.com so check it out!
6. Paul Chapman's put together a very good post explaining error handling strategies in Spring MVC
7. Daniel Lipp and Tobias Mattsson, from Magnolia, did a nice webinar introducing how to integrate the Magnolia CMS with Spring and Grails based applications. Cool stuff!
8. Greg Turnquist continues the narrative on Spring Boot and talks about how to add property support to a custom Spring Boot module.
9. Blogger Hébert Oliveira has put together an epic post on using Spring MVC, Spring Data, Spring Security, Bootstrap, and Angular.js together. Definitely worth a look!
10. I'm excited to see Thymeleaf 2.1 support for automatic Spring Security CSRF integration. Nice job!
11. Spring's documentation is now moving to Asciidoc! This is interesting mostly because it'll be easier to update and maintain the documentation now, and you can expect even better docs as a result!
12. Spring Boot tip thanks to Dr. Dave Syer: any bean of type TomcatConnectorCustomizer in a Spring Boot application will give you a callback reference to the Connector which you can then use to customize the embedded Tomcat instance. One possible application of this is applying SSL to the embedded Tomcat instance.
13. Speaking of Spring Boot, check out this Spring Boot Java app, a "full-featured" reference app that runs on @CloudFoundry that's designed to monitor builds. Nice job, Ben Hale!

NOTE: Revised April 2018

Spring MVC provides several complimentary approaches to exception handling but, when teaching Spring MVC, I often find that my students are confused or not comfortable with them.

Today I'm going to show you the various options available. Our goal is to not handle exceptions explicitly in Controller methods where possible. They are a cross-cutting concern better handled separately in dedicated code.

There are three options: per exception, per controller or globally.

A demonstration application that shows the points discussed here can be found at http://github.com/paulc4/mvc-exceptions. See Sample Application…

Spring Boot is continuing to gather steam. Last month I wrote Contributing to Spring Boot with a pull request. I peeled back the layers of Spring Boot to demonstrate it's incredible autoconfiguration features and CLI support.

In this post, I want to dig into Spring Boot's amazing support for properties. Properties are something that are small, not highly visible, yet can quickly strengthen your application in very practical ways. In this post, I'll walk through how I added property support to the Spring JMS support I coded in the previous blog post.

What are properties?

Properties are…

Welcome to another installment of This Week in Spring

I spent the weekend at the amazing Silicon Valley Code Camp event. It was an amazing event. People who visited the Pivotal booth got a chance to play with Spring Boot. People versed in Java, iOS, Python, .NET, Objective-C, and more all used Spring Boot to setup a RESTful service in a matter of minutes. To be honest, I found the results ("Wow! I didn't know you could do that!") both amusing and very satisfying! People are really getting into Spring Boot.

1. Speaking of Boot, did you miss Phil Webb's Spring Boot webinar? If so, don't worry! You can watch it online!
2. Roy Clarkson's announced the availability of Spring Mobile 1.1.0! The new release - as many of you know from having followed this roundup - features improved device detection in LiteDeviceResolver, tablet support in SitePreference and SiteSwitcher, a Java-based configuration API, and LiteDeviceDelegatingViewResolver. Nice!
3. Martin Lippert's just announced the latest and greatest cuts of the Spring Tool Suite and Groovy/Grails Tool Suite (3.4.0) which feature - among many other things - support for following the Getting Started Guides on the home of Spring - Spring.io. These releases also see updated support for Grails 2.2.4, and tc Server 2.9.3.
4. For more, check out the new & noteworthy. Both tool suites ship on top of the latest Eclipse Kepler SR1 release. The next version (3.5.0) is scheduled to arrive in March 2014, shortly after the Eclipse Kepler SR2 (4.3.2) release.
5. Did you miss the amazing Platform CF conference? Don't fret, the videos of the show are trickling up online. Ashwin Kumar, a principal Software Engineer at Pivotal, did a great job introducing Pivotal HD as a Cloud Foundry Service. Pivotal HD is the world's fastest Hadoop distribution, leveraging the mature SQL query engine known as HAWQ.
   
6. Not strictly Spring related, but there's a nice post on the GoPivotal blog on analyzing retail data using HAWQ and Madlib, the analytics (and machine learning!) engine originally part of Greenplum and now available to HAWK users. Nice post! This whole stack integrates nicely through Spring XD, of course, but even if it didn't, that's a really cool use case!
7. Did you miss SpringOne2GX 2013? Check out the first night's keynote featuring Pivotal CEO Paul Maritz, Adrian Colyer, David Syer, Juergen Hoeller, Chris Beams and Edward Hieatt!
8. Check out the replay of Param Rengaiah's webinar, Taming Coupling and Cohesive Beasts with Modularity Patterns and Spring!
9. Are you looking for the downloadable .zip distributions for Spring? We'll make them easier to find on our new site soon, but in the meantime, simply visit the Artifactory repository and type in spring-framework in the search field. Dig a bit and you'll find it. This a more direct link.

Welcome back to another installment of This Week in Spring! There is, of course, lots to talk about so let's get to it.

If you're in the bay area, I'd like to invite you to the Silicon Valley Code Camp this weekend. I'll be giving two talks - one on building RESTful Services with Spring and the other on Improving Spring Java configuration muscle-memory with the amazing Phill Webb. Pivotal will also have a booth there, and we'd love to see you!

1. Spring Data Arora SR3 has been released! The new release folds in Spring Data Commons 1.5.3, Spring Data JPA 1.3.5, Spring Data MongoDB 1.2.4 and Spring Data Neo4j 2.2.3. Nicely done, as usual, Oliver!
