A reminder: Every time somebody shows you a survey result with a Java EE 7 usage column, in particular when talking about production usage, double-check what they actually asked for. Does Hibernate 4.3 usage count as Java EE 7, just because it's JPA 2.1 (EE 7 level but run standalone)? Does Tomcat 8 usage count as Java EE 7, just because it's Servlet 3.1? And of course, does running a Spring application with any such individual providers count as EE 7?

Take such statistics with a big grain of salt: They typically do not ask for "native Java EE 7 platform usage" but are being presented that way eventually. Why is it a safe assumption that they did not ask for full Java EE 7 platform usage in production? Well, remember my blog post from back in June, which is still as valid in late 2015. In the meantime, the only real news is that there is no news since IBM released their EE 7 support in WebSphere's Liberty Profile. All in all, responders to such survey…

Webinar Replay: A Spring Showcase: Turkcell's Personal Cloud Storage App

Speaker: Erdem Gunay

Slides: http://www.slideshare.net/SpringCentral/erdem-gunay-springshowcasewebinar

Turkcell launched a personal cloud storage service few years ago. Adding new business features was costly in terms of time and budget on the legacy solution. The user experience needed to be improved. Finally, it was decided to build a new solution where Spring Boot and Spring Framework projects play crucial role as the backbone. The project was completed just in 6 months starting from scratch. The solution was built on top of Spring Boot and many Spring IO Platform projects, allowing the development team focus on business logic instead of configuration & integration details. The project has been divided into deployable modules (API, backend, migration, test automation) accessing micro services that are responsible for one task only. Join Erdem for a review of the migration effort and new architecture - all enabled by Spring Boot.

So you have decided to build an application using Spring Boot? Sooner or later, something will go wrong. It does not matter how experienced we are. How will Spring Boot help us figure out what went wrong and fix things? This talk introduces lots of tools to help us debug and manage "bootiful" apps. You will learn how to use Boot's autoconfiguration report, override Boot's settings & beans, create custom metrics/health checks/app info, and create custom JMX info & custom CRaSH commands.

Note that there's a follow-up blog post about Spring 5 system requirements. You might want to start there if you're primarily interested in the Spring 5 planning process.

In our quest for Java EE integration, we're trying to actively embrace the latest generation of specifications such as JPA, Bean Validation and of course the Servlet and JMS APIs. As of Spring 4, we're supporting the Java EE 6 and 7 level of specifications side by side. We would like to raise it to the EE 7+ level (JPA 2.1, Bean Validation 1.1, and in particular Servlet 3.1 and JMS 2.0) soon but are facing a fundamental problem: the lack of EE 7 platform…

As Josh mentioned in "This Week in Spring" already, Eugen Paraschiv recently did a noteworthy survey on the adoption of Spring 4 and Java 8 as well as Spring Boot: http://www.baeldung.com/java-8-spring-4-and-spring-boot-adoption

Those are interesting numbers for us. Within the Spring universe, Java 8 adoption seems to be approaching 40%! And in terms of Spring Framework versions, Spring 4 is at 65% already, which I'm really happy to see. Even taking into account that a large part of the corporate use of Spring might not be represented in those numbers, that's a great trend. And Pivotal's…

CI on the Cloud with Jenkins, Spring and Cloud Foundry

Speaker: Jamie O’Meara, Pivotal

This presentation will highlight an integrated development process that involves Spring code built with CloudBees Jenkins Enterprise and deployed to CloudFoundry. A software lifecycle of continuous delivery from source code control (Git) to Jenkins build (Maven and Gradle) to live deployment on a Cloud Foundry instance will be shown. We will demo using Jenkins to do a blue/green application deployment. With a Cloud Foundry blue/green Jenkins deployment, you can push a new version of the application and have a software router add that to an existing version of the application's route. The two versions are then load-balanced, allowing for testing of the new version and easy replacement or fall-back to the existing version. Developers can run builds on private and public clouds with deploy to either/both Jenkins running on a PaaS and integrated into the PaaS. We will run a hands-on demo and show the beauty and simplicity of an integrated build pipeline with Spring, Jenkins and Cloud Foundry.

Thymeleaf is a fantastic template engine that can help you create sites faster and get code shipped. There exists however a problem, using th e template engine requires a mind-shift in how to get "normal" tasks accomplished. This leaves many developers in the lurch and frustrated. In this talk I will cover the common pitfalls that developers can avoid and give examples on how to solve the common problems encountered when switching from the venerable JSTL to Thymeleaf.

Spring has been around since the release of “J2EE Design and Development” in 2002. Spring and Java have evolved quite a bit since that time. In those years a lot of applications have been developed. All those "legacy" applications that are around have proven their value and that is why they lasted. In this session we will explore how we can improve our legacy applications by doing some refactoring or redesign (component based development) but also by introducing (newer) Spring IO technologies.
