Welcome to another installment of This Week in Spring! This week I've been busily preparin for a workshop I'll be giving at QCon São Paulo next week. If you're at the show, I hope you'll come out to say hi, ask questions and we'll talk Spring and Cloud Foundry. Obrigado!

1. The replay on my humble webinar introducing Spring Session is online, check it out!
2. Janne Valkealahti has just announced the latest release of Spring Security Kerberos 1.0.0.RC1, packed with new features and now - at long last!! - near GA! Go Janne and team, go!
3. Spring and Groovy & Grails Tool Suite lead Martin Lippert just announced STS and GGTS 3.6.4.
4. I put together a post on getting started with Spring Data Couchbase
5. Spring XD ninjas Marius Bogoevici and Dr. Mark Pollack are going to be giving a webinar on April 28th that introduces using Spring XD and Apache Kafka…

This blog was inspired by a talk that Laurent Doguin, a developer advocate over at Couchbase, and I gave at Couchbase Connect last year. Merci Laurent!

This is a demo of the Spring Data Couchbase integration. From the project page, Spring Data Couchbase is:

The Spring Data Couchbase project provides integration with the Couchbase Server database. Key functional areas of Spring Data Couchbase are a POJO centric model for interacting with Couchbase Buckets and easily writing a Repository style data access layer.

What is Couchbase?

Couchbase is a distributed data-store that enjoys true horizontal scaling. I like to think of it as a mix of Redis and MongoDB: you work with documents that are accessed through their keys. There are numerous client APIs for all languages. If you're using Couchbase for your backend and using the JVM, you'll love Spring Data Couchbase…

Web / JavaScript Track

As the complexity of web and mobile apps increases, so does the importance of ensuring that your client-side resources load and execute in an optimal and efficient manner. Differences in resource loading, transforming, and fingerprinting techniques can have a dramatic impact on performance and caching. These techniques can dictate whether your users have a joyful or frustrating experience. Attend this talk to learn the SpringMVC performance techniques aimed at keeping your users happy.

Welcome to another installment of This Week in Spring! This week I'm in Kansas City, Kansas, hanging out with my pal and Spring Security lead Rob Winch. This week, I'm speaking at the local User Group and the Spring User Group, and I'll be talking to Cerner and a few other large businesses about Spring, Spring Boot and Spring Cloud.

As usual, we've got a lot of great stuff to talk about, so let's go to it!

1. Spring Boot co-lead Phil Webb just announced Spring Boot 1.2.2 and Spring Boot 1.1.11. Both releases are recommended upgrades, and Spring Boot 1.2.2 even includes new support for the Mustache templating library. Nice!
2. Check out John Hann's SpringOne2GX 2014 talk, introducing Rave.js, which brings Spring Boot-concepts to JavaScript
3. I put together a blog on building applications that use the Servlet HTTP session in a scalable manner and in a portable way - from application server, web server, and cloud - with ease.
4. Chris Beams's SpringOne2GX 2014 talk, The Revolution will not be Centralized…

A Framework for all Seasons (and Architectures)

Spring walks an interesting line. It provides a lot of value no matter where you run it, and - because it's built on dependency injection layer - it offers a natural piece of indirection between the underlying layer and the applications that run on top of it. This indirection promotes code portability through decoupling: your application code is ignorant of where the javax.sql.DataSource (or whatever) handle it's using comes from, be it a JNDI lookup, environment variables, or a simple new'd-up bean provided by Spring. This decoupling and the…

We are please to announce the release of Spring Security 4.0.0.RC2.

We were very keen on doing a GA release, but due to community feedback we decided that another RC was necessary. Ultimately, this release resolved nearly 50 tickets.

A summary of changes can be seen below:

• Support for enforcing Same Origin for WebSocket connections
• Refinements in WebSocket Configuration (SEC-2827 SEC-2833 SEC-2853 )
• More intuitive HTTP Response Headers Configuration (SEC-2846)

Assuming everything goes smoothly, the plan is to do a GA release in approximately two weeks. In the meantime, make sure to try…

Welcome to another installment of This Week in Spring! We've got a lot to cover so let's get to it!

1. Our pal Adam Koblentz (from ZeroTurnaround) put up this great post introducing building a websocket application with Spring Boot and JRebel. Check it out!
2. Check out this replay of Mark Fisher, Dr. Mark Pollack, and Sabby Anandan's webinar introducing Spring XD - A Platform for data at scale and developer productivity
3. A huge part of the Pivotal Data Suite, of course, is Spring XD. Last week I surfaced some of the amazing Spring XD wiki content on the new stream processing supports in Spring XD 1.1. Check out the Wiki page for a more detailed look by Spring XD ninja Ilayaperumal Gopinathan.
4. Spring Cloud co-lead Spencer Gibb has been improving the Spring Cloud Netflix integration. Check out this example demonstrating using RxJava's Observable<T> return-values from Spring MVC. Here are the changes…
