We are pleased to announce the availability of the Release Candidate for Spring AMQP 1.4; the GA is planned to be released in early November.

First of all, thank you all who provided feedback for the milestone 1.4 M1 version and submitted reports (bugs or new features). Special thanks to Stéphane Nicoll, who had introduced annotation-based message listeners (@RabbitListener) and the new RabbitMessagingTemplate.

Features and fixes included in this release (changes since the milestone)

• With the annotation-based message listener you can use the @SendTo annotation to send the result of the method as a reply message (when there's no replyTo in the inbound message):

Greetings Spring Community!

Today we have released a new tutorial written by Spring geek Josh Long, the man who travels the globe talking about Spring: Building REST Services with Spring

In this sleek tutorial, you can read about the simplicity and power of building RESTful web services using Spring. You'll also see how to:

• Test them with Spring's powerful MockMvc
• Secure them with Spring Security
• Plugin error handling
• Add hypermedia controls
• Dabble with OAuth
• See it all using Spring Boot

It's a really good read with LOTS of code (you know, the important stuff). What about the existing REST…

Earlier today, I announced the first milestone release of Spring Sync, a new project that addresses efficient communication between client applications and Spring backends by employing patch-based exchanges. As this is a new project, I thought it would be a good time to show you what Spring Sync can do.

The examples given here refer to the Spring REST Todos example and/or the Todo class in that example project.

Creating and applying patches

At its lowest level, Spring Sync provides a library for producing and applying patches to Java objects. The Patch class is the centerpiece of this library…

Dear Spring Community,

I am pleased to announce the first milestone release of Spring Sync 1.0.0.

Spring Sync enables efficient communication and synchronization of data between clients and Spring-based servers.

The release dependency is available in the repo.spring.io milestone repository at the dependency coordinates of "org.springframework.sync:spring-sync:1.0.0.M1".

This release includes:

• A patch abstraction for calculating differences and applying patches between Java objects.
• Support for representing patches as JSON Patch.
• An implementation of Differential Synchronization for creating and applying patches in a controlled manner.
• DiffSyncController, a Spring MVC controller that handles HTTP request of type application/patch-json+patch and performing Differential Synchronization against a resource.

Welcome to another installment of This Week in Spring! This week I'm talking to developers at the Neo4j GraphConnect conference with my pal (and Neo4j evangelist) Kenny Bastani, and then on Thursday I'll be doing a webinar with my one of my pals on the Vaadin team, Peter Lehto, on how to build Bootiful Vaadin applications - don't miss it!

Next week, I'll be doing a string of appearances at Toronto, New York City, and Boston meetups helping people better build microservices with Spring Boot, Spring Cloud and Cloud Foundry. Register now, come for the code, conversations, pizza and beer! Microservices are a big thing these days, and I'm sure there'll be a lot to talk about so don't miss these events!

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

• Reactor project lead Jon Brisbin giddily announced the first milestone for Reactor 2.0 which has as its headline feature the Reactive Streams API. The Reactive Streams API is a collaborative effort between Netflix, Typesafe, Pivotal, RedHat, and others that makes easier the task of handling backpressure in a reactive pipeline.
• Spring Data ninja Christoph Strobl has put together a nice look at what’s new in the latest and greatest Spring Data Evans release train.
• I hope you’ll join me this Thursday as Vaadin’s Peter Lehto and I introduce how to build Bootiful Vaadin rich UI applicatons.
• Then, mark your calendars for the good Dr. Syer's webinar introducing Security for Microservices with Spring and OAuth2
• Spring’s the most productive Java technology, but who wouldn’t like to squeeze more productivity out of the Java language itself by eliminating restarts and instead simply reloading changed byte code? JRebel can help! Adam Koblentz has put together two very cool posts looking at how JRebel can reload Spring XML configuration and how it can reload Spring MVC @Controller and @RestController-based @RequestMapping metadata.
• Speaking of Neo4j, they've just published some handy new guides (which they tell me were at least in part inspired by the Spring guides - blush!) that detail how to get started with Spring Data Neo4j and Spring Boot
• Comsysto Gmbh has put together a very nice look at Spring Boot and a Spring Boot applications lifecycle. He describes as, "his favorite timesaving, convention-enabling, autoconfig-creating, bean-making classpath-shaking microcontainer!"
• Readers of this roundup will know that we love JHipster, the Yeoman-based Spring Boot and Angular.js-code generator. JHipster just celebrated its first birthday! Joyeux anniversairre, JHipster!
• Nieraj Singh put together a detailed look at how to manage Cloud Foundry services in Eclipse with our Cloud Foundry plugin.
• Phillip Verheyden (from Broadleaf Commerce, the makers of a Spring-based e-commerce engine) wrote up his thoughts on SpringOne2GX 2014. Thanks, Phillip!
• You are following Groovy-language project lead Guillaume LaForge’s weekly roundup of all that’s awesome in the Groovy ecosystem, aren’t you?
• Check out this post on The Spring Way blog if you’re trying to marshall arrays of complex types back and forth with Spring’s RestTemplate.
• I always love reading Adrian Colyer’s blogs. Recently, he’s been reviewing one interesting academic paper per week. This last week he looked at a paper that offers that there’s not so strong a link between code-coverage and what that implies for (assurances about) code quality.

The Reactor team is frankly a little giddy at finally being able to announce an initial milestone release of Reactor 2.0! This update includes a fully-compliant Reactive Streams implementation in the completely re-written Stream and Promise APIs! This is a huge step for Reactor users. It opens up integration with other Reactive Streams implementations like Akka Streams, Ratpack, RxJava and others. Reactor provides a solid foundation upon which to build modern #uberfastdata applications with demanding high-throughput and low-latency requirements.

Stream and Promise

The headline change in Reactor 2.0 is the Stream API. In fact, most other parts of the codebase were either just lightly refined or remain untouched between 1.1 and 2.0. Not so with Stream and Promise. These components have been completely…
