Essential Grails Track

Slides: http://www.slideshare.net/SpringCentral/res-tful-grails2

Grails 2 includes a lot of features and functionality related to building RESTful services. These include an entirely new and more flexibile data binding system, runtime and compile time metaprogramming which greatly reduce the amount of code required in your RESTful services, a rich set of content negotiation tools and more.

Dear Spring community,

We are pleased to announce that the Spring Integration Kafka 1.0 GA extension is now available, providing familiar Spring Integration endpoints for Apache Kafka. As usual, use the Release Repository with Maven or Gradle

compile "org.springframework.integration:spring-integration-kafka:1.0.0.RELEASE"

or download a distribution archive, to give it a spin.

First of all thanks to all who contributed to the project - special thanks to the project's founder Soby Chacko, who implemented the infrastructure, as well as the High Level Consumer-based message source and the producers, and also to Marius Bogoevici, who learned the intricacies of the Simple Consumer API…

In this article we continue our discussion of how to use Spring Security with Angular JS in a "single page application". Here we show how to use Spring Security OAuth together with Spring Cloud to extend our API Gateway to do Single Sign On and OAuth2 token authentication to backend resources. This is the fifth in a series of articles, and you can catch up on the basic building blocks of the application or build it from scratch by reading the first article, or you can just go straight to the source code in Github. In the last article we built a small distributed application that used …

This post is a guest post by community member Tadaya Tsuyukubo (@ttddyy), creator of the Spring Social Slideshare project. Thanks Tadaya! I'd like to see more of these guest posts, so - as usual - don't hesitate to ping me! -Josh

Spring Social Slideshare is one of the community modules in Spring Social ecosystem. It is a Java binding built on top of the Spring Social framework to interact with the SlideShare REST API.

Spring Social modules provide an implementation of the ApiBinding interface that binds Java interfaces and concrete implementation classes to a REST API. By convention, an interface is named as target service, e.g. GitHub, LinkedIn, Facebook, etc. The implementation class is of the form *Template, e.g.: GitHubTemplate, LinkedInTemplate, and FacebookTemplate. In Spring Social Slideshare, there is a Slideshare interface and SlideshareTemplate implementation class. You can use spring to inject the SlideshareTemplate to your service. Or, if you choose to, you can directly instantiate …

Welcome to another installment of This Week in Spring! We've got a lot to cover, so without further ado, let's get to it!

1. Spring XD co-lead Dr. Mark Pollack's just announced that Spring XD 1.1 RC1 is now available! Now's the time to get the bits, try it out and see if there any gaps!
2. If you've been reading the amazing Dr. Syer's blogs of late, you'll know that he's been introducing people to how to use expose and secure REST services for a UI client. The fourth post looks at how to insert an API gateway between the clients and the backend service. The fifth post then introduces OAuth as a drop-in replacement for the bespoke authentication session tokens being used. If you're not following this series, do go back and reread them. This series treats a subject that I get asked…

Core Groovy Track

Slides: http://www.slideshare.net/SpringCentral/groovy-in-thelightofjava8

With Java 8 out the door, Java developers can, at last, benefit from the long-awaited lambdas, to taste the newly-found functional flavor of the language. Streams are there to work more easily and efficiently with heaps of data. Those things are not new to developers acquainted with Groovy. But what is left to Groovy to make it attractive beyond all the aspects Java has caught up with Groovy?

Big Data Track

Slides: http://www.slideshare.net/SpringCentral/spring-one2gx-2014springforapachehadoop

Leverage your existing Java and Spring skills when making the jump to write applications and workflows for Apache Hadoop. In this presentation we will introduce the Spring for Apache Hadoop project and see how it can make developing workflows with Map Reduce, Hive and Pig jobs easier, while providing portability across ASF, Cloudera, HortonWorks, and Pivotal distros. We'll also look at integration with Spring XD, batch jobs and external data sources. In addition to all this we'll show how use a mini-cluster to test your new Hadoop workflows without having to deploy to a full cluster.
