Welcome to another installment of This Week in Spring! This week I'm in Brisbane, Australia, on the second leg of the YOW! conference circuit. If you're around, please say hi or find me when YOW! moves to Sydney in a few days.

We've got a lot to cover so let's get to it!

• If you're not up to date with JUnit 5.0 and Spring Framework, this is a must - see talk from Sam Brannen at Swiftmind
• good news! the webinar introducing CQRS with Axon and Spring Boot that Axon lead and founder Allard Buijze and I delivered is now online
• Spring Integration lead Gary Russell just announced Spring Integration 5.0 M1. This release features a lot of nice new features and simplifies some older ones. One of my favorite features: it packages the Java DSL in the framework itself now, instead of a separate release! Get the bits, kick the tires.
• Janne Valkealahti has just announced Spring Statemachine 1.2.0.RC1…

Recorded at SpringOne Platform 2016. Speaker: Phil Webb Slides: none, all live coding In this talk we'll cover the host of new features that have been added to Spring Boot 1.4 to help with testing. We'll discuss how to unit test your code, how (and when) to involve Spring in your tests, and talk about the various tools and libraries that you should be using. Taking a simple application, we're going to add:

• Unit tests for basic components
• Integration Tests for JPA entities and queries
• Tests for JSON marshalling and unmarshalling
• Tests for Spring MVC controllers
• Tests for remote RestTemplate calls (using mocking)
• End-to-end integration tests (hitting a real HTTP endpoint)

Recorded at SpringOne Platform 2016. Speaker: Rob Harrop, Skipjaq Slides: http://www.slideshare.net/SpringCentral/going-reactive-building-better-microservices-rob-harrop

Reactive provides developers with an elegant model for constructing applications out of communicating components that improves code readability, eases concurrent programming and supports fine-grained unit testing.

In this talk, we'll see how this model is a natural fit for building resilient microservices. Specifically, we'll see how to:

Abstract the outside world behind Reactive interfaces Split a microservice into…

Recorded at SpringOne Platform 2016. Speaker: Sam Brannen, Swiftmind Slides: http://www.slideshare.net/SpringCentral/testing-with-spring-43-junit-5-and-beyond

Curious about what's new in Spring's testing support in 4.3 or what's on the horizon in Spring 5 and JUnit 5? Then join Sam Brannen, Spring Test component lead and JUnit 5 core committer, to find out! The first part of this session will give attendees an overview of the latest core integration testing improvements in Spring 4.3 such as the new SpringRunner alias for the SpringJUnit4ClassRunner, the omission of @ContextConfiguration…

Speakers: Josh Long, Allard Buijze

We get it already! Microservices let you decompose your application into small, singly-focused, reusable and internally consistent bounded contexts - services - deployed over a network.

Great, but that still doesn’t help me get these systems to agree on the worldview of my domain! And that’s because…there is no world view of the model that is correct for all services involved.

Join Axon framework founder and lead, Allard Buijze at Trifork and Spring Developer Advocate Josh Long, for a look at how to integrate different systems with different read and write…

We are pleased to announce that the first milestone for the 5.0 version of Spring Integration is now available.

This is a new major version, based on Spring Framework 5.0 and requires Java 8; this is the biggest change so far, but the following are also included:

• The Java DSL is now rolled into the framework itself; there are some minor changes to the DSL, such as the removal of the .handleWithAdapter() methods and some general Factory classes. A complete discussion of the DSL changes can be found in the Migration Guide.

• Upgrade to Spring Data Kay.

• Upgrade to Spring AMQP 2.0.

• First class support for TCP/UDP has been added to the DSL.

• Spring Integration is now based on Reactor 3.0 and Messaging Gateway Promise methods now have to be changed to return Mono.

• You can now configure mid-flow transactions via TransactionHandleMessageAdvice for adviceChain Messaging Annotations attribute and <transactional> sub-element when using XML configuration.

  …

We’re pleased to announce a release candicate of Spring Statemachine 1.2.0.RC1. Artifacts are available from Spring Repository.

What we got into this release:

• Usual bug fixes and small enhancements
• New api's for tracing and monitoring
• New monitoring sample
• Full repository config support for Redis, MongoDB and JPA
• Boot auto-config enhacements
• Lot of documentation enhacements

Full changes as usual are available from changelog. We're planning to fire up 1.2.0.RELEASE before xmas and possibly do a second release candicate if any major issues are found.

Thank you for all who have contributed in…

Recorded at SpringOne Platform 2016. Speaker: Mikey Cohen, Netflix Slides: http://www.slideshare.net/SpringCentral/netflixs-edge-gateway-using-zuul

An edge gateway is an essential piece of infrastructure for large scale cloud based services. This presentation details the purpose, benefits and use cases for an edge gateway to provide security, traffic management and cloud cross region resiliency. How a gateway can be used to enhance continuous deployment, and help testing of new service versions and get service insights and more are discussed. Philosophical and architectural approaches to…

Recorded at SpringOne Platform 2016. Speaker: Sergi Almar Slides: http://www.slideshare.net/SpringCentral/building-modern-web-applications-with-angular2

Web development has become more complex in the last few years with a plethora of frameworks to choose from and no clear direction. Join Sergi Almar in this presentation to learn why Angular2 is a good fit for Spring developers. We'll review the Angular2 architecture and see how TypeScript allows us to build more maintable and clean applications having the benefits of a typed language. We'll look at the Angular2 component based model…
