Speaker: Stephane Maldini, Pivotal

What is the role of asynchronous, non-blocking style-communication in microservices? Join Stephane Maldini for a revealing look at why reactive components are so important in an eventually-consistent approach like microservice architecture. When services own their data and are completely independent, having a (reactive) abstraction layer can perform a variety of roles. Being able to parallelize resources a microservice owns is an important technique. Another might be as an event bus, pulling state data from various micro services dynamically, checking against the cached, fairly up-to-date local copy. While a microservice has “all” the data it needs from other services to respond to a request, this data is not necessarily up-to-date—an important constraint to be prepared to accept. Stephane will also discuss other async use cases outside of microservices and how www.reactive-streams.org protocol support allows levels of portability across vendor implementations.

Welcome to another installment of This Week in Spring! This week I'm back in Silicon Valley, talking to developers at a handful of large technology-driven companies about taking their first steps with a cloud-native architecture. Interesting feedback, as ever! This week I'll be doing a meetup here in the bay area on building Bootiful microservices with Spring Cloud. Next week, I look forward to seeing people at Java2Days in Sofia, Bulgaria! C'ya there!

1. Spring Integration lead Gary Russell has just announced Spring Integration 4.1.0 and Spring AMQP 1.4.0 final are now available!

• Spring Security OAuth 2.0.4.RELEASE Available Now. The new release contains a few nice additions and a few bug fixes, making it a recommended, easy upgrade.
• Spring lead Juergen Hoeller just announced the availability of Spring Framework 4.1.2, accompanied by 4.0.8 and 3.2.12 maintenance releases.
• I'll be doing a webinar with ZeroTurnaround's Adam Koblentz introducing how to use Spring (and Spring Boot in particular) and JRebel 6…

Spring Boot 1.1.9 has been released and is available now from repo.spring.io and Maven Central.

This maintenance release includes a number of fixes and third-party dependency updates.

This release also upgrades to the latest Spring Framework, which includes an important security patch; as such it is highly recommended that all Spring Boot users upgrade.

I am pleased to announce that the first release candidate for Spring Boot 1.2.0 is available now in the Spring milestone repository. This release adds a number of improvements and new features over M2. Highlights include:

• Tomcat 8 or Jetty 9 as the default embedded servlet container (providing Servlet 3.1 support).
• A new @SpringBootApplication annotation.
• Access to start.spring.io using the spring init CLI command.
• Email support including a new spring-boot-starter-mail "starter POM".
• Additional health and metrics endpoints.

For a complete list of changes, and for upgrade instructions, see the Spring Boot 1.2 Release Notes on the WIKI. The reference documentation…

We are very excited to be recognized as the marketshare leader for the ESB and lightweight integration framework markets in DZone’s 2014 Guide to Enterprise Integration, a premium resource focused on enterprise integration and API management trends, strategies, and tools. The guide includes topic introductions, expert opinions, best practices, and solution comparisons. Readers of the guide will get an overview of enterprise integration and learn about obstacles that developers are facing to create seamless integration. Topics covered by the guide include:

• The role of message queues, middleware, and ESBs in the enterprise.
• Decomposition patterns for breaking down monolithic architecture.
• A model for understanding the maturity level of REST APIs.
• A forecast of how building a large project with multiple integrations might look in the future.

DZone’s Enterprise Integration guide also offers key insights into integration and API management practices through a survey of 500+ developers and experts, allowing readers to learn trends from practitioners in the technology professional community. Additionally, the guide’s solutions directory compares different API management platforms, integration suites, ESBs, message queues, and integration frameworks to help readers wisely choose the solutions they need.

Readers can download a free copy of the guide here.

About Spring Integration 4.1 GA release

Releasing on the same day as the DZone research, Spring Integration 4.1 GA offers 1st class Spring Framework 4.1, Java 8, WebSocket support. Longtime users will enjoy the new built-in EIP patterns, Redis Queue Gateway support. Most importantly, check out the soon-to-be-released Java DSL - very exciting. Rabbit users will also discover that Spring AMQP 1.4 GA makes full use of Spring Framework 4.1, and offers Rabbit messaging enhancements.

Dear Spring community,

It's my pleasure to announce the immediate availability of Spring Framework 4.1.2, accompanied by 4.0.8 and 3.2.12 maintenance releases.

Spring Framework 4.1.2 is our second maintenance release in the 4.1.x line but also comes as a key feature release, including many user-suggested and user-contributed improvements: in total, more than one hundred issues have been addressed. 4.1.2 also serves as the core framework release to go into Spring Boot 1.2 which is just around the corner...

-> List of resolved JIRA issues for Spring Framework 4.1.2

Note that aside from fixing…

Spring Security OAuth 2.0.4.RELEASE is available now in the usual repositories. It's a bug fix release, so upgrading is recommended, but there is also a small set of new features:

• The OAuth2Request (and hence OAuth2Authentication) can now be

queried explicitly to find the grant type for the associated token. If the token is being refreshed the grant type in the OAuth2Request presented to a TokenEnhancer is the original grant type, not "refresh_token".

• The client authorities are exposed in the "/check_token" endpoint

• Password grants are more flexible and open to extension because both client and server can add additional parameters to the request. A custom AuthenticationManager on the server side should still expect a UsernamePasswordAuthenticationToken, but the additional parameters will be available in the AuthenticationDetails. Multi-factor authentication for mobile devices could be implemented in this way, for instance.

• Keystore support for JWT token signing and verification.

…

Dear Spring Community,

Following on from the recent announcements of release candidates for Spring Integration and Spring AMQP, we are extremely pleased to announce that Spring Integration 4.1.0.RELEASE and Spring AMQP 1.4.0.RELEASE are now available for download.

On Nov 12, 2014, DZone research recognized Spring Integration as the leader of the ESB / Integration framework space, leading with 42% marketshare, in a publication of their recent survey results.

Many thanks to all contributors, including several who are new to the community.

The releases are available now in the Spring repository…
