Spring Framework 4.3.5, 4.2.9 and 3.2.18 available now

It is my pleasure to announce that the Spring Framework 4.3.5, 4.2.9 and 3.2.18 maintenance releases are available now.

4.3.5 is a significant refinement release with 37 enhancements (including e.g. WebSocket support for the recently released Jetty 9.4) and several bug fixes, serving as the basis for the upcoming Spring Boot 1.4.3 release.

Please note that the 4.2.9 and 3.2.18 bug fix releases are the last in their respective line, with 4.2.x being superseded by 4.3.x now and 3.2.x reaching its EOL point. Going forward, we expect all users to upgrade to 4.3.5+ for further support.

Vaadin Spring 1.1 - build web UIs that hook right to your Java backend

This post is a guest post by community member Matti Tahvonen (@MattiTahvonen), who works as a developer advocate in Vaadin Ltd, the company that originally developed Vaadin Framework and provides commercial services and extensions for it.

The first stable release of the official Spring integration library for Vaadin was released a bit over a year ago. The feedback has been great and many Spring developers, who have wanted to stay on the safe “backend side”, have discovered a new way to use their existing Java skills to build good-looking web UIs. Using Vaadin Spring, your UI code lives in Spring managed beans and the integration with your Spring based backend becomes trivial.

Custom test slice with Spring Boot 1.4

Spring Boot 1.4 includes a major overhaul of testing support and one of these features is test slicing. I’d like to take the opportunity in this blog post to further explain what it is and how you can easily create your own slices.

Test slicing is about segmenting the ApplicationContext that is created for your test. Typically, if you want to test a controller using MockMvc, surely you don’t want to bother with the data layer. Instead you’d probably want to mock the service that your controller uses and validate that all the web-related interaction works as expected. This can be summarized in the example below:
