Welcome to another installment of This Week in Spring!

If you're in the bay area this week, I'll be speaking at the Netflix OSS meetup in Los Altos talking about Spring Cloud on Wednesday and at Pivotal San Francisco's Open-Source Hub on the amazing Spring Session project on Thursday. I hope you'll join me for either or both! It's sure to be fun!

As usual, we've got a lot to cover, so let's get to it!

1. My pal (and Spring Boot co-founder!) Phil Webb and I gave the introduction to Spring Boot lesson at SpringOne2GX 2014 - check it out! Hopefully you'll have as much fun as we did! :)
2. DZone have published two nice Developers of the Week profiles, one for the good Dr. Dave Syer and one for Spring Batch lead Michael Minella
3. Adib Saikali put together a really nice article on InfoQ introducing the ways that Java 8 and Spring 4 win.
4. Readers of this roundup will know that I love me some JHipster, and so I am super excited to have JHipster founder Julien Dubois…

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.

Essential Grails Track

Slides: http://www.slideshare.net/SpringCentral/securing-yourgrailsapp2gx2014

Application security is not a concern that we can ignore. Vulnerabilities come from various angles, but it is important to stay aware and vigilant so we can recognize and thwart threats.

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.

Essential Grails Track

Slides: http://www.slideshare.net/SpringCentral/testing-grails

Grails comes with extensive testing support, ranging from unit to integration to functional tests. This session will demonstrate the range of options available both natively and through testing plugins. Prerequisite: Some knowledge of Grails would be helpful but not assumed.

Learn the roles of cache clustering, session clustering, and quartz clustering with open source Terracotta, Quartz, and BigMemory.

It was about six months ago that we started work on the 2.1 version of Spring for Apache Hadoop. We are now pleased to announce the general availability of version 2.1.0.

Beginning with the Spring for Apache Hadoop 2.1 version, we now only support Hadoop 2.0 APIs and no longer provide backwards compatibility with older Hadoop v1 distributions. If you need support for older Hadoop versions please use the 2.0.4 or 1.1.0 versions of Spring for Apache Hadoop.

The main new features for the 2.1 version are:

Configuration and Boot support:

• New @Configuration changes and improvements to the Boot auto configuration features. A good example of this support can be seen in the boot-fsshell DemoApplication example app

More Groovy Track

Slides: http://www.slideshare.net/SpringCentral/testing-java-groovy-spring-and-web-applications-with-spock

Spock is a popular testing framework (mainly) for Java and Groovy applications. After a short introduction, I will discuss Spock's Java and Groovy specific features, will show how Spock can be used for integration testing of Spring applications, and how combining it with Geb yields a powerful solution for acceptance testing of web applications. Finally, I will demonstrate how Spock can be extended to build out the test infrastructure for your project, and will showcase the latest features planned for the mythical Spock 1.0 release.
