Spring Framework 4.1.7 & 3.2.14 released

Dear Spring community,

I’m pleased to announce that the Spring Framework 4.1.7 and 3.2.14 maintenance releases are available now. Aside from fixing various minor issues across the framework, these releases also address an XML parsing vulnerability through disabling DTD processing by default when parsing untrusted XML input in Spring MVC endpoints.

Note that Spring Framework 3.2.x has its End-of-Life scheduled for December 31, 2016. Based on demand and vulnerability reports, further maintenance releases will be made available up until then. At the same time, we strongly recommend a migration to Spring Framework 4.1.7 or the upcoming 4.2 at this point; please plan accordingly!

Spring REST Docs 1.0.0.M1

I’m delighted to announce that Spring REST Docs has reached its first milestone and that 1.0.0.M1 is available from https://repo.spring.io/milestone.

Spring REST Docs helps you to document RESTful services. It combines hand-written documentation written with Asciidoctor and auto-generated snippets produced with Spring MVC Test. This approach frees you from the limitations imposed by tools like Swagger. It helps you to produce documentation that is accurate, concise, and well-structured. This documentation then allows your users to get the information they need with a minimum of fuss.

This Week in Spring - June 23, 2015

Welcome to another installment of This Week in Spring! I was in London, last week, for Devoxx UK. The show was a rousing success all around. I gave a talk, a workshop, and was delighted to participate in the closing keynote, too! This week I’m in Kraków, Poland, for Devoxx Poland (né 33rd Degree) which seems to be an amazing success as well! I want to thank the organizers (Mark Hazell and Grzegorz Duda of Devoxx UK and PL respectively) for inviting me - I haven’t had this much fun in a while and I love the communities that both events serve.

Spring Integration Kafka 1.2 is available, with 0.8.2 support and performance enhancements

We are pleased to announce the release of Spring Integration Kafka 1.2.

This new release provides a couple of major improvements and upgrades over the previous versions:

  • Support for Apache Kafka 0.8.2 and using the new Producer API;
  • Overhaul of the internal concurrent dispatching with a non-blocking ring buffer implementation based on Project Reactor.

For each of the changes, the goal was to improve the performance of the producer and, respectively, consumer components of Spring Integration Kafka. While we do not have any isolated benchmarks for Spring Integration Kafka proper, the enhancements of the release have contributed to the performance metrics reported in the newly released Spring XD 1.2.

Spring Guides Move to Java 8

Perhaps you’ve noticed some recent articles lately?

Okay, those last two aren’t articles, but were instead driven by the the rapid adoption of Java 8. Java 8 has been picked up by the development community FAST. Here on the Spring team, we believe strongly in adopting Java 8 for new applications. To support that and improve your own ability to move as well, we just updated all of the Spring Getting Started Guides to Java 8.
