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…

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…

Spring Data Release Evans has been around for a while and it's more than time to finally introduce you to the latest and greatest features we shipped with it.

There's a lot to cover since major enhancements have gone into the commons module. Those changes already have made it into some store modules and will go on and sneak their way into others over time, too. All of them are already available for at least Spring Data JPA. That said, lets jump right in.

Advanced support for Java 8

Java8 has now been around for a while and previous Spring Data release trains already added fundamental support…

Welcome to another installment of This Week in Spring! This week I've been at Silicon Valley Code Camp, JAX London and Geekout UK talking to developers about how to build scalable, microservice-centric Spring Boot applications on Cloud Foundry. It's been a lot fun talking to enthusiastic developers (on both sides of the Atlantic!).

Without further ado, let's get on with the roundup!

• Spring Boot co-lead Phil Webb just announced the availability of Spring Boot 1.2.0.M2 which includes, among other things, auto-configuration for Jersey, log4j, commons-dbcp support, a smarter disk usage health indicator and improved RabbitMQ support
• Spring and Groovy Tool Suite lead Martin Lippert has just announced the latest and greatest release, 3.6.2, which is a maintenance release that includes an update to the latest Eclipse Luna SR1 installation.
• Also, Spring Boot co-lead Phil Webb just announced the 1.1.8 release of the 1.1x line of Spring Boot…

Welcome to another installment of This Week in Spring! This week, I've been at the Couchbase Connect conference talking to developers about Spring Data Couchbase (and Spring Boot, Spring XD, Spring Session, and more..). Fun show, fun crowd! Next week, I'll be at JAX London and Geekout UK, so be sure to say hi if you're around.

Now, with that, let's get on to the roundup..

1. The good Dr. Pollack just announced the 1.0.1 release of Spring XD, the easiest way to build data-integration and ingestion solutions. It may be only a 1.0.1 release, but make no mistake: there are some very cool features in this release, including improved administrative and administrative UI features.
…

We're exploring ways to help developers create rich, modern front-ends that integrate easily with Spring back-ends. If you attended SpringOne this year, you've already seen some of the things we've been working on:

1. Hypermedia support in Spring Data REST presented by Greg Turnquist, Oliver Gierke, and Roy Clarkson
2. RaveJS: Spring Boot concepts for JavaScript applications by John Hann
3. Differential Synchronization and JSON Patch by Craig Walls and me

In short, We want to make it easy to communicate efficiently between a Spring back-end and a client and to easily integrate the best and most…

Welcome to another installment of This Week in Spring! This week the Spring team is at JavaOne! There's been, and will be, lots to see! We're also hanging out at the booth, talking to as many users as possible. Check out the link I just give listing all the cool Pivotal (and non-Pivotal) talks at JavaOne. (Ahem. Naturally, I personally would love it if you made my talk - Spring4TW! - tomorrow morning at 8:30am at Parc 55, Cyril Magnin II/III!).

In addition to IoT, Big Data, and Microservice demos using NetFlixOSS on Spring, students were doing the coding challenge to build a REST service with Spring Boot and pushed to Pivotal Web Services in < 15 minutes to get the preshavedyak hoodie from American Apparel, and learning about the best PaaS for Java available on the market today; Java 8 / Tomcat 8 support was released just days ago, and there is strong support for Spring, Groovy and Grails.

• I really liked Michael Plod's Why I Recommend Spring webinar, now available online as a replay
• Last week, Activiti BPMN2 engine co-founder Joram Barrez and I gave a talk on how to build process (read: workflow) centric Spring applications, also now available online.

• There's been an interesting debate on microservices recently. "Uncle" Bob Martin has written up a post claiming that .jars and Ruby gems give you the same benefit of microservices. There's a great rebuttal (which I happen to agree with..) by Giorgio Sironi on his blog. There's even a nice wrapup of the whole discussion on InfoQ.
• I really dig Matt Stine's wind tunnel comparison of PaaSes. Up first: Heroku. I can't wait to see subsequent posts in the series!
• This post on using Spring Data Redis was published (and included in TWiS..) last year, but it came up again and I still thnk it's a worthy read
• The eHarmony blog has a nice post on how to setup Spring Batch Admin (the tricky parts..)
• In the you have to see it to beleive it department, did you know there's a Spring for Delphi (Spring4D) project? There are Spring-inspired C++, ColdFusion, JavaScript, .NET, Python, and numerous others. Cool to add this to the list.
• The Intertech blog has another installment on their epic Spring Integration tutorial. This one's on service activators - basically the Spring Integration escape-hatch so you can call regular Java objects.
• Benjamin Ball has a great writeup on using RabbitMQ and Spring
• Yashwant Chavan has a nice post on building a simple Spring Boot (with Spring MVC) example and editing it in Eclipse.
• Our pals at Codecentric are at it again! They've just released their first cut of their Spring Boot Admin. This looks like something that would fit nicely in the Spring Cloud project...

Speaker: Derek Beauregard Contributors: Phil Berman, Darrel Sharpe, Michael Minella In this demo we will explore the power of Spring XD in the context of the Internet of Things (IoT). We will look at a solution developed with Spring XD to stream real time analytics from a moving car using open standards. Ingestion of the real time data (location, speed, engine diagnostics, etc), analyzing it to provide highly accurate MPG and vehicle range prediction, as well as providing real time dashboards will all be covered. Watch this demo to get a sense of how Spring XD can serve as a critical…
