What’s new in Spring Cloud Task 1.0.3.RELEASE

1.0.3.RELEASE represents the next minor release for the 1.0.x branch. It’s a minor update that cleans up the dependency management within the project to be in alignment with how the rest of the Spring Cloud portfolio manages it’s dependencies.

I am pleased to announce that the second milestone for Spring for Apache Kafka version 1.1.0.M2 is now available in the spring milestone repo.

This includes some bug fixes and the following new features:

The ability to process a batch of messages (introduced in the last milestone) is now available when using the @KafkaListener annotation, for example…

@KafkaListener(id = "list", topics = "myTopic",
                          containerFactory = "batchFactory")
public void listen(List<String> list) {
    ...
}

September 5, 2016

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 Security OAuth2 - Client Authentication Issue

Joe Grandja

August 31, 2016

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.

However, if you’re using XML-based configuration, please take the following actions:

Update to 2.0.11.RELEASE
Look at this JUnit test and it’s associated XML configuration to ensure the AuthenticationManager for client authentication and the AuthenticationManager for user authentication is setup the same in your configuration.
As a precautionary step, make sure your XML configuration is NOT setup the same as in this JUnit test and associated XML configuration as it demonstrates the original issue.

Custom test slice with Spring Boot 1.4

Stéphane Nicoll

August 30, 2016

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 the example below:
