Speakers: Jon Brisbin, Stephane Maldini Reactor was recently made public after a two-year incubation, evolving slowly alongside frameworks like Storm, Akka, Play, GPars or Vert.x. Integrated with Grails starting with version 2.3, Reactor takes the best ideas from several asynchronous toolsets and synthesizes them into a coherent framework that supports a variety of runtime topologies and makes it easy for developers to efficiently leverage their cloud or traditional hardware assets. Reactor is equally at home inside or outside a Spring ApplicationContext and also provides first-class Groovy support in the form of DSLs and language extensions. Special attention has been given to make Reactor easy enough to use to create single-file node.js-like applications, while maintaining a solid asynchronous toolset that works with Big and Fast Data tools like Gemfire, Spring Integration, and Spring Batch. This talk will give Reactor a proper introduction and show sample code that demonstrates the event-driven and composition-based nature of Reactor applications.

I'm pleased to announce the first milestone release of Spring Test MVC HtmlUnit.

The project’s aim is to provide integration between Spring MVC Test and HtmlUnit. This simplifies performing end to end testing when using HTML based views.

Stay tuned to the Spring Blog for a mini blog series introducing this exciting new library. If you can't wait to get your feet wet, refer to the project's Getting Started section on GitHub.

Yesterday, the 12th of March, 2014, was the 25th anniversary of Sir Tim Berner's Lee having invented the web. As he explains: "I just had to take the hypertext idea and connect it to the Transmission Control Protocol and domain name system ideas and—ta-da!—the World Wide Web." Elementary, really. (Hah!)

Pictured (taken from Wikimedia) is the original NeXT workstation (whose operating system , NeXT Step, underpins today's OS X and iOS design) on which Sir Tim Berners-Lee put together the initial HTTP service and client.

As an aside: I've always wondered what it would be like to be able to…

On behalf of Michael Nitschinger, I'm happy to announce the 1.0 GA release of the Couchbase Spring Data module.

Between the last release candidate and the final release, several bugs have been fixed and new features have been added. Notable additions are the support for custom converters, JSR-303 Validation support and built-in support for temporal objects like Dates, Calendars and similar JodaTime variants.

The release artifacts are available via Maven Central. You can find the reference documentation, JavaDoc and a change log at the usual expected places.

From now on, the Couchbase module will be part of the official Spring Data release trains, starting with Dijkstra. Now that the first GA release is out of the door, we will put…

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

1. Spring AMQP lead Gary Russell has just announced that Spring AMQP 1.3.0 has just been released!
2. Spring Social lead Craig Walls just announced the first, long-awaited, RC of Spring Social 1.1. Hurray! I'm excited to see this new release.
3. Spring Security lead Rob Winch has just announced a security fix for Spring Security 3.2.2 and 3.1.6.
4. Dr. Dave Syer, co-lead on Spring Boot, among many, many other amazing things, has thrown together a sexy looking Spring Boot wrapper for Ratpack, a toolkit for JVM web applications. That's so awesome.
5. Spring Data lead Oliver Gierke has just announced that the first service release for Spring Data Babbage is now available
6. I put together a post on the various deployment strategies for Spring Boot applications
7. Don't miss Mattias Arthursson on a webinar March 18th, presenting Spring LDAP 2.0.0.
8. Join Juergen Hoeller and the Spring Team for a webinar on Java 8 and Spring Framework 4.0 on March 25!
9. Speaking of Spring Data, check out the replay of this talk introducing Spring Data repository best practices from SpringOne2GX 2013
10. Don't miss John Hann's introduction to pragmatic JavaScript from SpringOne2GX 2013
11. Emanuel Rabina gave a talk at SpringOne2GX 2013 on improving your Spring view layer with natural templates and Thymeleaf: check it out!
12. The More Vaadin blog has a nice, if short, post on the Spring Boot/ Vaadin integration that Vaadin's Petter Holmström and I have been working on . Nice! As always, this is open-source so don't be shy and be sure to send any feedback you have.
13. In related news, snapshots of the Vaadin4Spring integration that Petter and I are working on are now published on Sonatype's repository - enjoy!
14. Our pal Eberhard Wolff is back, and this time he's written up a nice (German-language) post on Spring 4.0 and Spring Boot, among (many) other things
15. David Williams blog, A Time-to-Value Story with Cloud Foundry, is thought-provoking: how quickly can a technology deliver value - measurable value?
16. Martin Fowler has started watching the micro services space. Nothing to report, specifically. This is just a page I'd recommend watching.
17. Layer 7, a CA technologies company, has just released results of a survey focused on API design and deployment. There are many takeaways from the survey, so be sure to read it, but one thing I thought particularly promising: a predicted growth in Hypermedia-aware APIs among API developers. If you're interested in embracing hypermedia, and the design pattern HATEOAS, I would encourage you to check out Spring HATEOAS and - if you'd like to learn more about using Spring HATEOAS and Spring Boot, check out this tutorial and adjoining code.

Spring Security 3.2.2 (change log) and 3.1.6 (change log) have been released and are available in Maven Central.

Among the highlights, these two releases resolve CVE-2014-0097 which allows a malicious user to impersonate a user with an empty password if ALL of the following hold true:

• The application is using ActiveDirectoryLdapAuthenticator
• The directory allows anonymous binds (not recommended)

NOTE: This does NOT impact users of LdapAuthenticationProvider or <ldap-authentication-provider>

For full details on the releases, please refer to the previously mentioned change logs.

Dear Spring Community,

I'm happy to announce the availability of Spring Social 1.1.0.RC1 as well as Spring Social Facebook 1.1.0.RC1, and Spring Social Twitter 1.1.0.RC1. These release candidates are the first step toward a GA release coming soon. They include several improvements, bug fixes, and a few new features, including:

• New Thymeleaf 3 and 4 dialects to match Spring Social's JSP tag library.
• A generic connection factory for quick configuration of an API for which there is no formal connection factory support. Provides a RestOperations as the API binding.
• Optimized use of RestTemplate in API bindings when using Spring 3.2+.
• A new streamlined and more flexible Java configuration option.
• SecurityConfigurerAdapter for enabling provider-based authentication with Spring Security's Java configuration.
• A pluggable session-abstraction.
• Support for Facebook's built-in OpenGraph actions in the API binding.
• …

Speaker: Emanuel Rabina

With the disconnect between the languages of the web (HTML, CSS, Javascript) and the languages of the server (Java, Groovy, Scala, etc), many libraries and frameworks have been invented over the years to fill this void, often resulting in views filled with back-end code, views filled with specialized syntaxes, or even the invention of completely new view languages abstractions; all for the purpose of transforming our server-side ideas into HTML, and few of which actually look like the HTML that it ends up as. Enter Thymeleaf - a templating framework that uses HTML to create good old HTML. In this presentation, you'll be introduced to Thymeleaf, some of its features, how you can use it in your Spring web projects, the growing ecosystem being developed around it, and how it uses natural templates to keep the web designer on your team, and inside each and every one of us, happy.
