"Bootiful" Java EE Support in Spring Boot 1.2

In this blog, I want to look at - and demonstrate - some of the many new features in Spring Boot 1.2 that make the lives of those coming from, or otherwise building on, Java EE easier.

It's worth mentioning that a lot of this support has been possible with Spring before, of course, but now with Spring Boot 1.2, it's just so darned easy!

First, here's an example program with notes after.

        private EntityManager entityManager;

        public void createGreeting(String name, boolean fail) {
            Greeting greeting = new Greeting(name);
            this.jmsTemplate.convertAndSend("greetings", greeting);
            if (fail) {
                throw new RuntimeException("simulated error");

        public void createGreeting(String name) {
            this.createGreeting(name, false);

        public Collection<Greeting> findAll() {
            return this.entityManager
                    .createQuery("select g from " + Greeting.class.getName() + " g", Greeting.class)

        public Greeting find(Long id) {
            return this.entityManager.find(Greeting.class, id);

    public static class Greeting implements Serializable {

        private Long id;

        public String toString() {

        public Greeting(String name) {
            this.message = "Hi, " + name + "!";

        Greeting() {

    public static class GreetingServiceClient {

        private GreetingService greetingService;

        public void afterPropertiesSet() throws Exception {
            try {
                greetingService.createGreeting("Josh", true);
            } catch (RuntimeException re) {
                Logger.getLogger(Application.class.getName()).info("caught exception...");

    public static class GreetingMessageProcessor {

        @JmsListener(destination = "greetings")
        public void processGreeting(Greeting greeting) throws JMSException {
            System.out.println("received message: " + greeting);

    public static void main(String[] args) {, args);

Spring Boot 1.2.0.RC2 Available Now

I am pleased to announce that the second release candidate for Spring Boot 1.2.0 is available now in the Spring milestone repository. This is mainly a bug fix release, although we did manage to sneak in a fantastic community contribution which adds support for Undertow as an embedded Servlet container.

For a complete list of changes, and for upgrade instructions, see the Spring Boot 1.2 Release Notes on the WIKI. The reference documentation has also been updated to cover new features.

As usual, please report any problems using the project Issue tracker.


Spring Roo 1.3.0 introduces JDK 8 support

On behalf of the Spring Roo team, I am pleased to announce the release of Spring Roo 1.3.0, the first version released by DISID Corporation as project lead.

Spring Roo is a rapid application development tool for Java, allowing you to create full web enterprise applications in just minutes.

This is the first time that Spring Roo jar files have been published to Maven Central! As always, the release is available in the Spring IO repository.

The 1.3.0 release includes bug fixes and enhancements as well as several new features:


Screencast: How to create a RESTful app in five minutes or less

Recently, a friend of mine tweeted out a challenge:

"Name a framework in which you can create a new app expose a REST service with a database and deploy it to the cloud in five minutes. #grails"

The moment I spotted that tweet, I responded, "Spring Boot + Spring Data REST"! I realized he was kindly pointing out how easy it is to build RESTful services with Grails (a great framework). But I couldn't resist showing the ease and power of Spring Data REST.

To prove my point, I couldn't resisting crafting a screencast. In the linked screencast, I show how über easy Spring has made it to pick the parts for your app from, define your domain, and then export them as a hypermedia-driven RESTful service.

SpringOne2GX 2014 Replay: Developer Tooling - What’s New and What’s Next

Recorded at SpringOne2GX 2014.

Speakers: Andy Clement, Martin Lippert


In this talk we take a look at the latest changes and new features of the Spring Tool Suite, the Eclipse-based IDE that comes packed with support for Spring, Groovy, Grails, Gradle, AspectJ, and Cloud Foundry. We dive into the new ways the tooling makes it easy and convenient to develop enterprise applications that are based on Spring Boot and how the Spring Tool Suite integrates will all the different parts of Spring IO. In addition to that we will show the Java8 language tooling that comes as part of the Spring Tool Suite and demonstrate how to get the most out of Java8 in your projects. In the second part of this presentation we take a look at our vision for how we are going to move developer tooling itself into the cloud era. We provide a sneak peek under the hood of what we are working on for the next generation of developer tooling. We will demonstrate what future cloud-based developer might look like, how real Java language tooling can look and feel when running in a browser-based code editor, and show how every developer can smoothly migrate into this new world of cloud-based developer tooling. All this is based on Flux, a new project at, that aims at providing new and innovative ways to move towards cloud-based tooling in a smooth, seamless way.


SpringOne2GX 2014 Replay: Java 8 Language Capabilities, What's in it for you?

Recorded at SpringOne2GX 2014.

Speaker: Venkat Subramaniam

No Slides at speaker request

There is a good amount of excitement about the new version of Java. The big evolution of course is the lambda expressions. In this presentation we will dive into the language features in Java 8, take a look at some of their nuances, and look at ways to put them to good use. In addition to looking at lambdas we will also dive into the Streams capabilities and also some of the features in Java 8 that make all these possible.


SpringOne2GX 2014 Replay: What's new in Spring Data?

Recorded at SpringOne2GX 2014.
