Spring Cloud Data Flow 2.3.0.M1 and 2.2.1 GA Released

Engineering | Ilayaperumal Gopinathan | September 06, 2019 | ...

The Spring Cloud Data Flow team is pleased to announce the milestone release 2.3.0.M1 and the release of 2.2.1 GA.

Along with the bug fixes and enhancements, the first milestone of 2.3.0 also has the following new features:

  • Improved Prometheus monitoring based on Prometheus RSocket. It uses persistent bidirectional (RSocket) connections between the Stream/Task applications and a Prometheus RSocket Proxy instance. When Prometheus scrapes the proxy instance, and the proxy, in turn, uses the connections to pull metrics from the applications.
  • Ability to pass OAuth Access Token as command-line arguments for Composed Tasks
  • Users can now specify a description of the stream when creating it. Thanks to Daniel Serleg for the contribution!
  • Spring Cloud Scheduler SPI is now merged into Spring Cloud Deployer. We’ll deprecate the explicit spring-cloud-scheduler project and its implementations on Cloud Foundry, K8s and have them available as part of spring-cloud-deployer

Spring HATEOAS 1.0.0.RC2 released

Engineering | Greg L. Turnquist | September 05, 2019 | ...

Dear Spring community, we’re proud to announce the second release candidate of Spring HATEOAS 1.0.0. Since our last release, Spring HATEOAS has made great strides with two more milestones and two RCs.

Here’s the summary:

  • Internationalization support for both HAL and HAL-FORMS.

  • Performance improvements

  • Spring HATEOS is now based on Spring Framework 5.2 and Reactor’s Dysprosium release train. This is critical to support downstream projects like Spring Data Moore and Spring Boot 2.2.

  • Now supports Spring WebFlux applications that have both hypermedia and non-hypermedia endpoints.

  • Improved major chunks of reference documentation.

  • Created a Spring HATEOAS Gitter channel.

  • Fixed issues in various media types to ensure they comply with spec definitions, and don’t throw unexpected exceptions.

Hi Spring fans! Welcome to another installment of This Week in Spring! We've just finished celebrating Labor Day here in the Long home, in San Francisco, in the US.

We are pleased to announce the third Milestone of the Spring Cloud Stream Horsham.M3 (3.0.0.M3).

Securing Services with Spring Cloud Gateway

Engineering | Ben Wilcock | August 16, 2019 | ...

So far in this series, we've covered Getting Started and Hiding Services with Spring Cloud Gateway. However, when we set about hiding our services, we didn't secure them. In this article, we'll correct this.

To secure our services, we'll use the Token Relay pattern supported by OAuth 2.0 and the Javascript Object Signing & Encryption (JOSE) and JSON Web Tokens standards. This will give our users a means to identify themselves, authorize applications to view their profile and access the secured resources behind the gateway.

All the code for this demo is published online in GitHub in the secured-gateway folder. If you just want to run it without understanding how it was built, skip ahead to the section entitled "Running The Demo".
