Whats new in Spring Data Evans?

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 for some of those. With the Evans release train we extended the support significantly.

This Week in Spring - Tuesday October 14th, 2014

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!

This Week in Spring - October 7th, 2014

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.
  2. Federated security is an important part of any distributed, multi-client, (micro)service-oriented system. Spring Security and Spring Security OAuth, in particular, provide a compelling solution. Join the good Dr. Dave Syer for this upcoming webinar on microservice security using OAuth2
  3. Matt Stine will be doing a webinar introducing how Pivotal Cloud Foundry and Spring Cloud make for a natural solution to building microservices. Don't miss this one!
  4. Spring and JavaScript ninja Brian Cavalier has written a very interesting post on some of the work we're doing towards enabling easier differential sync between JavaScript clients and services. This post not only introduces all these exciting new stuff, but also builds on RaveJS, the Spring Boot-inspired approach to JavaScript.
  5. I hope you'll join the Vaadin team and I on October 23rd for a look how to build Spring Boot-powered Vaadin applications.
  6. Justin Lee Grant has put together a good introductory look at Spring Boot.
  7. Spring lead Juergen Hoeller just announced the 4.1.1 release of Spring framework. This release includes improved Optional handling, a Jackson ObjectMapper builder, some requested JDBC improvements, and much more.
  8. The good Dr. Syer just announced the first milestone release of the Spring Cloud project. Spring Cloud provides primatives for building microservice and PaaS-centric applications. It builds on top of the Netflix OSS stack and Spring Boot.
  9. Karthik Abram put together a nice post on a hidden gem in Spring: the ClassPathScanningCandidateComponentProvider class, which makes it easy to discover beans of a certain type.
  10. Nicolas Lejeune has written up a fascinating look at how he managed to convert a legacy application (it uses EJB3) and move it to a Cloud Foundry environment
  11. Our pal Toshiaki Maki put together his ideal Spring Boot Maven archetype, and shared it!
  12. Are you a Groovy fan? (who isn't??) Check out Groovy project lead Guillaume LaForge's weekly roundup, This Week in Groovy!
  13. Do you want to debug applications deployed on Cloud Foundry? Daniel Mikusa put together a very nice post explaining one approach.

Streaming JSON Patch from Spring to a React UI

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 popular client-side technologies.

Spring Cloud 1.0.0.M1 Available Now

Spring Cloud (the new umbrella project announced in September) has reached a milestone, its first, and fresh jars are available in the repo.spring.io repository. Spring Cloud is going to follow a "release train" model for releases, a bit like Spring Data, but we haven't got a cool name for this one yet, so it's just 1.0.0.M1. The modules that are part of this release are

  • Spring Cloud Config: Centralized external configuration management backed by a git repository. The configuration resources map directly to Spring Environment but could be used by non-Spring applications if desired.

  • Spring Cloud Netflix: Integration with various Netflix OSS components (Eureka, Hystrix, Zuul, Archaius, etc.).

  • Spring Cloud Bus: An event bus for linking services and service instances together with distributed messaging. Useful for propagating state changes across a cluster (e.g. config change events).

  • Spring Cloud Security: A set of primitives for building secure applications and services with minimum fuss.

  • Spring Cloud CLI: Spring Boot CLI plugin for creating Spring Cloud component applications quickly in Groovy.

  • Spring Cloud Starters: Spring Boot-style starter projects to ease dependency management for consumers of Spring Cloud.
