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…

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.

  …

On behalf of the Spring XD team, I am very pleased to announce the general availability of Spring XD 1.0.1!

This release includes bug fixes and enhancements as well as some new features:

• HTTPS access and Authentication to Admin Server
• Cluster and Stream views in UI
• Configure a location for custom modules
• Null sink

You can download the zip distribution or install on OSX using homebrew. On RHEL/CentOs you can install using yum.

Feedback is very important, so please get in touch with questions and comments via

• StackOverflow spring-xd tag
• Spring JIRA or GitHub Issues

Dear Spring community,

I'm pleased to announce that Spring Framework 4.1.1 is available now. As the first maintenance release in the 4.1 line, this release contains a wide range of fixes for regressions and other issues reported against 4.1 GA. A big thank you to all the issue reporters out there!

4.1.1 also comes with a selection of minor enhancements, for example: consistent handling of Java 8's Optional type, a Jackson ObjectMapper builder class with refined defaults, some requested JDBC refinements, as well as specific performance improvements.

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.
• Tuesday, Oct 21st, 2014 join Matt Stine for microservice architecture series #2: Architecting for Continuous Delivery: Microservices with Pivotal CF and Spring Cloud
• Thursday, October 23, 2014, 2014 Building “Bootful” UIs with Spring Boot and Vaadin
• Tuesday, November 4, 2014 - microservice architecture series #3 - Join Dr. Dave Syer on Security for Microservices with Spring and OAuth2
• Missed microservice architecture #1? Catch the replay of Building "Bootiful" Microservices with Spring Boot on the Spring Developer Channel
• Spring Boot 1.1.7 is now available!
• Setup Spring Security with Active Directory LDAP in Spring Boot Web Application (I just got asked about this at the Spring BOF yesterday!)
• 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...
• This has to be one of the coolest Spring Boot presentations, ever! Careful, I don't recommend watching it full-screen if you get motion sickness! :)
• Are you stuck on Apache CXF but still want first-class security? This post looks at how to plugin Spring Security on top of CXF in minutes
• Biju Kunjummen did a nice job clarifying the differences between Spring's WebApplicationInitializer and ApplicationContextInitializer

Speaker: Josh Long, Pivotal and Vaadin

It's been a long day, but you've done it: you've got a Spring Boot powered backend and now you need to build the UI that'll power the workforce and deliver next week. Vaadin, a UI framework that marries the ease of use of server-side Java and the rich, dynamic nature of client-side JavaScript, integrates well with Spring Boot and offers UI polish that would be hard to secure any other way. Join Spring developer advocate Josh Long and Vaadin evangelists for a look at how Vaadin and Spring Boot can get you to production quicker, and easier.

Security for Microservices with Spring and OAuth2 OAuth2 is a lightweight security protocol that is well-suited for use with HTTP, the protocol at the heart of many modern architectures. Spring Security OAuth2 has a load of new features, not the least of which being the `@Configuration` support in version 2.0. Combine these with Spring Boot and you have a platform which can get you a secure HTTP service application in about 20 lines of code. This presentation shows how the combination of rapid development and production-ready features in the modern Spring stack are a perfect mixture for developing secure components in a system composed of microservices. We explore the new features in Spring OAuth2, guide you through the choice of which to use and when, and show how easy they are to enable quickly.
