We’re pleased to announce a first milestone release of Spring Statemachine 1.2.0.M1. Artifacts are available from Spring Repository.

What we got into this first milestone:

• Usual bug fixes and small enhancements
• Support for UML submachines
• New Repository abstraction keeping machine configuration in an external repository
• New support for state actions.
• New transition error action concepts

There has been a support for complex state hierarchy from a day one but trouble was that everything had to be defined in a same state configuration. New submachine support adds a feature where a state can be…

After more than a year of work, multiple milestones and fine tuning based on much feedback, I have the pleasure of announcing Reactor 3 General Availability. You will find Reactor Core 3.0.2.RELEASE on Maven Central.

What is Reactor 3 ?

Reactor 3 provides a powerful and efficient reactive programming model for Java 8 based applications. The model builds upon the experience of both Reactor 2 and RxJava 1 and introduces a fluent way to compose asynchronous backpressure-ready event processing. Spring Framework 5 uses Reactor 3 to build and eventually expose a complete reactive story.

Its design relies on an extensible execution model that favors event processing colocation. Typically, Reactor will be jumping threads between event flow stages only when explicitly asked so. For instance, in-memory operations such as list access or payload transformation do not usually require a thread boundary. If the operation producer or receiver might take time, users are expected to operate their flow with Flux#publishOn / Mono#publishOn or Flux#subscribeOn / Mono#subscribeOn and choose a Scheduler to run on. Alternatively, if a user is combining the results of many Publisher as with …

Dear Spring Community,

I’m pleased to announce that the Java DSL for Spring Integration 1.2 RC1 is available now.

Since the previous Milestone 2 we had a good deep feedback for our new features and some API has been broken to reflect real requirements.

As usual, big thanks to everyone who created issues, raised Pull Requests, provided feedback or just asked questions on StackOverflow.

The artifact org.springframework.integration:spring-integration-java-dsl:1.2.0.RC1 is available in the Milestone repo. So, give it a shot for last chance to raise a GH issue for any feedback!

Now about the changes in the 1.2 RC1…

Wow! It's already almost October! This year has sure gone by quickly!

Welcome to another installment of This Week in Spring! This week I'm in the studio with Phil Webb recording the next installment of our Livelessons series on building Microservices with Spring Boot. It's been a lot of fun so far and we've only just begun!

Tonight, I hope you'll join me for Cloud Native Java on the vJUG's worldwide and live event going on in timezones all around the world!

We've got so much to cover, so let's get to it!

On behalf of the team, I am excited to announce the General Availability of Spring Cloud Data Flow for Apache Mesos 1.0.

Spring Cloud Data Flow for Apache Mesos provides support for orchestrating long-running (streaming) and short-lived (task/batch) data microservices on Apache Mesos. We launch stream apps using Application Groups on Marathon and tasks as Chronos one-time jobs. The release includes a template JSON script for deploying the Spring Cloud Data Flow server on Marathon. We also include sample scripts for deploying Redis, MySQL and Rabbit MQ on Marathon to be used for testing a…

Developing cloud native applications presents several challenges. How do microservices discover each other? How do you configure them? How can you make them resilient to failure? How can you monitor the health of each microservice?

Spring Cloud addresses all of these concerns. Even so, you still must explicitly develop your own discovery server, configuration server…

Spring Framework 4.3 is the last in the 4.x generation and it brings plenty of refinements to the @MVC programming model. In Spring Framework 5.0 the same programming model will be supported on a new reactive foundation. This talk will review the main features in 4.x and preview the work towards Spring Framework 5.0.

On behalf of the team, I am happy to announce the general availability of the Spring Cloud Camden Release Train along with Service Release 6 of Brixton. Camden.RELEASE can be found in our Spring Release repository. You can check out the Camden release notes for more information. Brixton.SR6 is largely a bug-fix release and is recommended for use with the Brixton Release Train.
