Application events are available since the very beginning of the Spring framework as a mean for loosely coupled components to exchange information. One of the most well known usage of application events is the following:

@Component
public class MyListener 
        implements ApplicationListener<ContextRefreshedEvent> {
  
    public void onApplicationEvent(ContextRefreshedEvent event) {
        ...
    }
}

This allows MyListener to be notified when the context has refreshed and one can use that to run arbitrary code when the application context has fully started.

Recently James Ward wrote a great blog post, “Java Doesn’t Suck – You’re Just Using it Wrong”, which highlighted numerous challenges that enterprise Java developers face in their daily routines building Java applications. The good news is that breaking out of the development rut is much easier than you may think. Over the last few years, Spring has redefined how modern Java applications are built while dramatically improving development velocity. In this post, I’ll use James Ward’s blog post as a backdrop to explain how Spring helps developers rock the JVM (using Java) while tackling each of…

An API's documentation is a vital part of making it easy to understand and easy to use. RESTful APIs are no different. In this webinar we'll look at what should be included in your RESTful API's documentation and, just as importantly, what should be omitted. To illustrate this we'll look at some real-world examples of good and bad API documentation. We'll look at some of the problems and limitations of choosing a tool like Swagger to produce your API's documentation and conclude by looking at some alternatives that are better-suited to producing documentation that your users will love.

Webinar: Introducing the Java DSL for Spring Integration

Speaker: Gary Russell

Slides: https://speakerdeck.com/garyrussell/spring-integration-java-dsl-a-deeper-dive

The Spring Integration JavaConfig and DSL extension provides a set of convenient Builders and a fluent API to configure Spring Integration message flows from Spring @Configuration classes. The Java DSL for Spring Integration is essentially a facade for Spring Integration. The DSL provides a simple way to embed Spring Integration Message Flows into your application using the fluent Builder pattern together with existing Java and Annotation configurations from Spring Framework and Spring Integration as well. Another useful tool to simplify configuration is Java 8 Lambdas.

Ratpack is an asynchronous web framework for the JVM that was inspired by the simplistic nature of Ruby's Sinatra framework. Written in Java, optimized for Groovy and Java 8, Ratpack sports a high throughput, simplistic interface for rapid development of rich, real-time web applications.

More Groovy Track

Slides: http://www.slideshare.net/SpringCentral/traits-design

Groovy 2.3 introduces the concept of traits in the language. Traits look like interfaces, but allow the developer to add both implementation and state into it. It introduces multiple inheritance in the language while avoiding the diamond problem. Traits will let you rethink the way you design APIs in Groovy, by favoriting composition of behaviors.

G&G Special Topics

Slides: http://www.slideshare.net/SpringCentral/continuous-delivery-with-gradle-and-jenkins

Getting software from a developer's machine to a production environment without a fully automated process is time-consuming and error-prone. Continuous Delivery enables building, testing and deploying of software through build pipelines with well-defined quality gates. In this session, we will discuss how to build such a pipeline with the help of Gradle and Jenkins. With Jenkins as the centerpiece of our build pipeline, we will model our way from build to deployment. We will start by introducing an examplary application and learn how to build it with Gradle. Step by step, we will touch on topics like automating unit, integration and functional tests, incorporating popular code quality tools, as well as packaging, publishing and deploying the deliverable.
