Dear Spring Community,

I'm very happy to announce the general availability of Spring Social 1.1.0. Along with the release of the core Spring Social project, Spring Social Facebook 1.1.0, Spring Social Twitter 1.1.0, and Spring Social LinkedIn 1.0.0 are also now available.

These releases include several new features, including:

  • Simplified Java and XML configuration support
  • A new ReconnectFilter to automatically reestablish a connection when a token has expired or been revoked
  • Updated API bindings for Facebook, Twitter, and LinkedIn
  • A generic connection factory for APIs where there is not (yet) connection framework support
  • Tighter Spring Security integration, including SocialAuthenticationFilter for provider-based sign-in
  • Thymeleaf template support
  • Updated documentation
  • ...and much more...

Spring Boot 1.0.2.RELEASE is available now in the Spring and Maven Central repositories. This is mostly a bug-fix release (nothing major, but please upgrade if you are using an older version). There are also a couple of nice new features.

My favourite additions are the new @IntegrationTest features. Here's an example:

@SpringApplicationConfiguration(classes = SampleActuatorApplication.class)
public class SampleActuatorApplicationTests {

    private int port;



DISID to lead Spring Roo Project


We are happy to announce that Pivotal and DISID will collaborate on further development of the Spring Roo project. Roo will continue in its goal of providing a code-gen style of RAD framework, focused helping developers get Java projects done on time.

Pivotal and DISID were already in collaboration around Roo for some time, so we’re excited to be formalizing what originally was an informal, developer led partnership – a partnership that DISID is committed to. The Spring Roo project will remain as an open source project under Spring, maintaining the same current licensing policy. Both Pivotal and DISID are calling on the Spring and Java communities for anyone who would like to collaborate in the project with us!


Welcome to another installment of This Week in Spring! This week I'm in Bangalore, India, for the Great Indian Developer Summit talking to developers about (wait for it..) Spring! I also met with a large system integrator here in Bangalore's Electronic City and addressed a large team of architects and engineers using Spring on projects worldwide. India's an interesting place because so much of their business comes from companies abroad who are trying to get extra help on otherwise overwhelming projects. Naturally, anything that helps get more done, quicker, is of interest here and Spring's a favorite. Needless to say, Spring Boot resonated a lot! It's not all work, though, when the local food is as good as it is here! :)

Creating a secure application involves more then just applying Spring Security to it. This is of course not a new topic, but with the increased popularity of much more dynamic configurations for Servlet Containers and various Spring Projects, like Spring MVC and Spring Integration, it becomes more important to know about the Security tradeoffs we might get with that, and how to tackle them.

Speaker: Costin Leau, Elasticsearch

Finding relevant information fast has always been a challenge, even more so in today's growing "oceans" of data. This talk explores the area of real-time full text search, using Elasticsearch, an open-source, distributed search engine built on top of Apache Lucene. The session will showcase how to perform real-time searches on structured and non-structured data alike, how to cope with types and suggestions, do social graph filters and aggregations for efficient analytics. All from a Spring perspective Last but not least, the presentation focuses on the Hadoop platform and how Map/Reduce, Hive, Pig or Cascading jobs can leverage a search engine to significantly speed up execution and enhance their capabilities. The presentation covers architectural topics such as index scalability, data locality and partitioning, using off and on-premise storages (HDFS, S3, local file-systems) and multi-tenancy.

Spring Data Neo4j 3.0 is here and it supports Neo4j 2.0. Neo4j is a tiny graph database with a big punch. Graph databases are imminently suited to asking interesting questions, and doing analysis. Want to load the Facebook friend graph? Build a recommendation engine? Neo4j's just the ticket. Join Spring Data Neo4j lead Michael Hunger (@mesirii) and Spring Developer Advocate Josh Long (@starbuxman) for a look at how to build smart, graph-driven applications with Spring Data Neo4j and Spring Boot.

The Spring Integration team has been hard at work on the latest release of the popular integration framework. Before version 4.0, it was impractical to define a complete Spring Integration flow without using XML. With this major release, the existing basic annotation support has received an overhaul and those who prefer to use java @Configuration classes can now define their applications without needing to use any XML (of course, XML is still supported as well). In this session we will cover these major changes to the framework, explaining how and when to use them. It will be mainly demonstration and code walk through, and we will build a useful Spring Boot / Integration application from scratch.


As I'm sure most readers are aware, Java SE 8 was released last month. In conjunction with the recent release of STS 3.5.0 and its complete support for JDK 8, we thought now would be an ideal time to upgrade Sagan to take advantage of the new language features and APIs.

Note: Not yet familiar with the Sagan project? It's the Spring reference application that powers this blog and everything else at Check out the first three posts in this series for more details.

Cloud Foundry's Java buildpack has provided support for JDK 8 since the day it was released. To begin using it, we've created our own fork of the buildpack, bumped the JDK version from 1.7.0 to 1.8.0, and configured our Gradle build to use our fork when deploying Sagan to production.


Spring Security OAuth 2.0.0.RC1 is available now from the Spring Repo. This is a huge step in the direction of modernisation and ease of use for OAuth server and client apps on Spring.

The headline feature is support for @Configuration(for OAuth2 only) and if you use Spring Boot to write your app you can serve tokens and protect the API resources in about 25 lines of code:

public class Application {

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

    public String home() {
        return "Hello World";

    protected static class OAuth2Config extends AuthorizationServerConfigurerAdapter {

        private AuthenticationManager authenticationManager;

        public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {

        public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
                    .authorizedGrantTypes("password", "authorization_code", "refresh_token")
                    .authorities("ROLE_CLIENT", "ROLE_TRUSTED_CLIENT")
                    .scopes("read", "write", "trust")
