Welcome to another installment of This Week in Spring! This week I'm at the Rich Web Experience in Ft. Lauderdale, FL, joining my pal Matt Stine for a workshop on building microservices with Spring Boot, Spring Cloud and Cloud Foundry.

So, without further ado, let's get to it:

• Dr. Dave Syer just announced the M3 release of Spring Cloud, complete with loads of cool stuff, including a smarter Ribbon-enabled load-balancing RestTemplate, a RabbitMQ-based aggregator for Hystrix Metrics based on Turbine 2, Spring Cloud for AWS support, and much more
• Spring ninja Sebastien Deleuze just announced some of the amazing new features in Spring's Jackson support. My favorite? JSON + XML marshalling with dynamic views. Views are a logical subset of attributes from a JSON structure that may be rendered dynamically.
• Check out Spring Roo 1.3.1 and includes bug-fixes for reverse engineering and third party addon installations. Thanks, community and Disid in particular for the updates!
• Spring and Groovy & Grails Tool Suite lead Martin Lippert just announced versions 3.6.3. The new release includes updated Spring Integration visualizations, a installed-by-default Cloud Foundry plugin and more. Check it out!
• Want to learn about the Spring Integration Java configuration DSL in terms of a working, line-by-line example? Check out this post by Java configuration DSL lead Artem Bilan and if you want to see how it works on JDK 7 or earlier, check out this post.
• Spring Data lead Oliver Gierke just announced the first milestone of the next Spring Data release train, Spring Data Fowler.
• The replay from the good Dr. David Syer's SpringOne2GX 2014 talk on security for microservices is now available online.
• Additionally, check out Dr. Syer and Spencer Gibb's talk introducing Spring Cloud to the world at SpringOne2GX 2014!
• Check out the SpringOne2GX 2014 replay of Reactor project ninjas Jon Brisbin and Stephane Maldini's talk: Building Reactive applications with Reactor and the Reactive Streams standard
• Join Spring Integration project-lead Gary Russell for a not-to-be-missed webinar on January 27th that introduces the just-released Spring Integration Java configuration DSL!
• You know what they say: go grid or go home! Or something like that…​ anyway, definitely check out my pal Luke Shannon's upcoming webinar on building scalable data applications with Spring Data Gemfire
• Adao Feliz put together a nice post on using Spring Boot and Docker. It's pretty straightforward, so check it out!
• The All and Sundry blog has a nice post on how to consume linked resources using Spring's RestTemplate.
• Check out the early bits for the next-gen Cloud Foundry built from the ground up on the Go language and supports Docker as a first-class citizen. If you know how to use Vagrant, it's dead simple to get a full working Cloud Foundry cloud running on your laptop if you follow these instructions. Do try it out and let us know!

Dear Spring Community!

Recently we published the Spring Integration Java DSL: Line by line tutorial, which uses Java 8 Lambdas extensively. We received some feedback that this is good introduction to the DSL, but a similar tutorial is needed for those users, who can't move to the Java 8 or aren't yet familiar with Lambdas, but wish to take advantage

So, to help those Spring Integration users who want to moved from XML configuration to Java & Annotation configuration, we provide this line-by-line tutorial to demonstrate that, even without Lambdas, we gain a lot from Spring Integration…

Egads! Can you believe it's already almost the end of the year? Time has been screaming fast! It's the week of Thanksgiving for those of us in the United States. This is a wonderful time of year to sit back, find a nice Spring IO guide or blog to read, and then build something awesome.. oh, and it's an ideal time to spend in the company of friends and family and to reflect on those and that for which we're grateful. I'm sure I speak for the Spring team and Pivotal at large when I say that we're grateful for you, our inspiring community, users and customers.

But if you do want something to read…

Dear Spring Community!

Just after the Spring Integration Java DSL 1.0 GA release announcement I want to introduce the Spring Integration Java DSL to you as a line by line tutorial based on the classic Cafe Demo integration sample. We describe here Spring Boot support, Spring Framework Java and Annotation configuration, the IntegrationFlow feature and pay tribute to Java 8 Lambda support which was an inspiration for the DSL style. Of course, it is all backed by the Spring Integration Core project.

For those, who are not interested in Java 8 yet, we provide similar tutorial without Lambdas: Spring Integration Java DSL (pre Java 8): Line by line tutorial…

In this blog, I want to look at - and demonstrate - some of the many new features in Spring Boot 1.2 that make the lives of those coming from, or otherwise building on, Java EE easier.

It's worth mentioning that a lot of this support has been possible with Spring before, of course, but now with Spring Boot 1.2, it's just so darned easy!

First, here's an example program with notes after.

package demo;

import org.glassfish.jersey.jackson.JacksonFeature;
import org.glassfish.jersey.server.ResourceConfig;
import org.springframework.boot.SpringApplication;
import org.springframework.boot…

Recently, a friend of mine tweeted out a challenge:

"Name a framework in which you can create a new app expose a REST service with a database and deploy it to the cloud in five minutes. #grails"

The moment I spotted that tweet, I responded, "Spring Boot + Spring Data REST"! I realized he was kindly pointing out how easy it is to build RESTful services with Grails (a great framework). But I couldn't resist showing the ease and power of Spring Data REST.

To prove my point, I couldn't resisting crafting a screencast. In the linked screencast, I show how über easy Spring has made it to pick the parts for your app from http://start.spring.io, define your domain, and then…

On behalf of the Spring XD team, I am very pleased to announce the first milestone release of Spring XD 1.1 and the 1.0.2 maintenance release.

Welcome to another installment of This Week in Spring! This week I'm in sunny Sofia, Bulgaria for the Java2Days software conference. As usual, this show is way too much fun and the crowd's bigger and better than ever!

1. Spring Boot 1.2.0 RC1 is now available! This release moves embedded Servlet containers to Tomcat 8 or Jetty 9, adds a new @SpringBootApplication annotation, adds JavaMail support, and registers additional Spring Boot actuator support
2. Spring Session 1.0.0.RC1 is here with loads of features!
3. Speaking of using Spring with ZeroTurnaround, join ZeroTurnaround's Adam Koblentz and I on Nov 20th as we look at using JRebel and Spring Boot to deliver a one-two developer productivity punch without equal
4. Want to learn more about the Reactor project and the role of asych I/O in microservices? Check out the upcoming Reactor webinar…

Spring Integration 4.1 was just released and it includes a lot of great new features! One of my favorites? Smart integration with the Spring 4 WebSocket support. Now you can compose a integration flow whose final destination is a WebSocket client. There is also support for acting as the client to a WebSocket service.

In order to compile it, you will need Java 8 (we make heavy use of lambdas here) and the following Maven dependencies:

• groupId:org.springframework.integration, artifactId:spring-integration-java-dsl, version: 1.0.0.RC1.
• groupId:org.springframework.integration, artifactId:spring-integration-websocket, version: 4.1.0.RELEASE.
• groupId:org.springframework.boot, artifactId:spring-boot-starter-websocket, version: 1.2.0.RC1.
