Welcome to another installment of This Week in Spring! This week I'm in Shanghai, China and Hangzhou, China where I spoke at the ginormous Huawei Connect conference in Shanghai and where I'll be working with Alibaba and Huawei for a week or so. I'll also be speaking at the Hangzhou Java User Group, too.

(Can you believe we're already in September?? Seriously blown away! 2017 is just around the corner!)

I'm also, technically, on vacation, so I'll keep this post to a minimum! :)

• Spring REST Docs lead Andy Wilkinson has just announced Spring REST Docs 1.1.2
• Spring Security ninja Joe Grandja just announced a very important fix for Spring Security OAuth 2
• Spring ninja Stéphane Nicoll put together a very interesting article on how to write a custom spring Boot test slice
• our buddy Eugene is back at it again, with updates to his guide on using Spring Cloud's Netflix Hystrix support
• learn more about Spring Cloud's Config Server in this nice post from Ian Collington.

Issue #808 was recently reported that allowed a user to authenticate as a client and obtain an access token via the client_credentials or password grant flow.

This unique scenario occurs when a client and user have the same identifier (clientId and username). The user’s credentials are used for client authentication during a client_credentials or password grant flow and is successful in obtaining an access token with the authorities of the client.

The Fix

This bug has been fixed in 1ed986a and released in 2.0.11.RELEASE.

If you’re using Java-based configuration, please update to 2.0.11.RELEASE…

It's my pleasure to announce that Spring REST Docs 1.1.2.RELEASE is available from Maven Central, JCenter, and our release repository. My thanks to everyone who contributed to this release by reporting bugs and opening pull requests.

This maintenance release includes a number of bug fixes and is a recommend upgrade for all Spring REST Docs users.

Spring Boot 1.4 includes a major overhaul of testing support and one of these features is test slicing. I'd like to take the opportunity in this blog post to further explain what it is and how you can easily create your own slices.

Test slicing is about segmenting the ApplicationContext that is created for your test. Typically, if you want to test a controller using MockMvc, surely you don't want to bother with the data layer. Instead you'd probably want to mock the service that your controller uses and validate that all the web-related interaction works as expected. This can be summarized in…

Welcome to another installment of This Week in Spring! This week I've been in San Francisco, (where I live and) where I addressed the Silicon Valley Spring User Group. Now it's off to beautiful China to bring some Spring and Pivotal (and, maybe, take a little vacation!)

As usual, we have a lot to get to so let's!

Greetings Spring community,

Spring Web Services has just released versions 2.3.1.RELEASE and 2.4.0.RELEASE.

2.3.1.RELEASE is a minor patch release.

2.3.1 Release Notes | 2.3.1 Documentation.

2.4.0.RELEASE rebases Spring Web Services to run on Spring Framework 4.2.x & Spring Security 4.0.x, the stable baselines behind Spring 4.3/Spring Security 4.1. At the same time, it remains compatible with Java 7. This version includes changes to the code base making it forward compatible with Spring 4.3 and 5.0, so you are free to move up to whichever version of Spring/Spring Security you wish to use.

2.4.0 Release Notes | 2.4.0 Documentation…

On behalf of the team, I am pleased to announce the release of the first milestone of the Spring Cloud Stream Brooklyn release train. Spring Cloud Stream Brooklyn.M1 is available for use in the Spring Milestone repository, a detailed description of its features can be found in the reference documentation. Release notes are available here and include important information on the migration path.

From a Monolith to a Release Train

We are pleased to announce the 1.0.0.RC2 release candidate of Spring Cloud Data Flow for Mesos, a team effort that encompasses many new features under the hood.

This release candidate builds upon the recent 1.0 GA release of Spring Cloud Data Flow. Some highlights include:

• We now run the Spring Cloud Data Flow Server as a Docker image on Marathon, a container orchestration platform for Mesos.
• This release adds features to support stream partitioning and scaling

• Currently partitioning and scaling of sinks and processors are handled by using multiple application deployments, one for each app instance, identified by an index appended to the name.
• Scaling of sources is handled by using additional application instances.

* Streams are now deployed using Marathon [Application Groups](https://mesosphere.github.io/marathon/docs/application-groups.html) so it is easier to identify the different apps making up a stream. * We have added support for launching tasks using Chronos, a fault tolerant job scheduler for Mesos.

As part of this effort we have developed a simple Java client for interacting with the Chronos API. This Java client is included in the latest 1.0.2.RELEASE version of the Spring Cloud Deployer for Mesos project…
