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 associated with other machine which allows some level of re-use and makes configuration more clean.

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!

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.

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.

Highlights of the Camden Release Train

Spring Cloud Contract is a new project that provides support for Consumer Driven Contracts and service schemas in Spring applications. Spring Cloud Netflix supports customization of Ribbon component classes via properties, uses the new community-maintained OpenFeign and includes various fixes and improvements to Zuul. Spring Cloud Consul adds support for Spring Cloud Bus using Consul’s event API. The CLI adds a spring cloud command to start various Spring Cloud servers with a single command. Supported servers include Eureka, Config Server and Hystrix Dashboard.

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.

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, and circuit breaker dashboard for monitoring the circuit breakers in each microservice.

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 complete deployment. In addition to running on an Apache Mesos cluster, we also support running on a Mesosphere DC/OS cluster.

On behalf of the team, I am happy to announce the general availability of the Spring Cloud Contract in version 1.0.0.RELEASE. You can download it from Spring Release or Maven Central. The reference documentation is available here. The release notes are available here.

What is Spring Cloud Contract for? What you always need is confidence in pushing new features into a new application or service in a distributed system. Spring Cloud Contract project provides support for Consumer Driven Contracts and service schemas in Spring applications, covering a range of options for writing tests, publishing them as assets, asserting that a contract is kept by producers and consumers, for HTTP and message-based interactions.
