This new release includes lots of amazing new features so be sure to check it out! It includes anotation detection on Java 8 default methods, annotation-based application events, first-class annotation attibute aliases, nest path processing for direct field binding, data binding and conversion for JSR 354 (money and currency), Hibernate ORM 5.0 support (via JPA and natively), a STOMP client for use over TCP and WebSocket channels, Listenable/…

Dear Spring community,

It's my pleasure to announce that Spring Framework 4.2 RC1 is now available from our milestone repository. This is a feature release in the 4.x line with a focus on core refinements and modern web capabilities:

• Annotation detection on Java 8 default methods (e.g. @Bean)
• Annotation-based application events (@EventListener)
• First-class support for annotation attribute aliases
• Full nested path processing for direct field binding
• Data binding and conversion for JSR-354 Money & Currency
• Integration with Hibernate ORM 5.0 (natively and via JPA)
• Rich support for CORS and declarative HTTP caching
• First-class support for HTTP Streaming and Server-Sent Events
• Listenable/CompletableFuture as message handler return value
• A STOMP client for use over TCP and WebSocket channels

I’m pleased to announce the availability of Spring Cloud Connectors 1.2.0 RC1.

This release should be fully backward compatible with 1.1.0.RELEASE for applications using the library. Libraries that extend the core Connectors library should be recompiled against 1.2.0 RC1, and may encounter a few small extension API changes. Barring any issues, this will be the only RC before 1.2.0.RELEASE.

Here's an overview of what's new in 1.2.0:

Spring Cloud Connectors Core

AMQP

• AmqpServiceInfo no longer validates that the path element of a URI contains a value, which allows the default RabbitMQ vhost to be used.
• URL validation in AmqpServiceInfo was relaxed such that QPID URL format is supported as well as RabbitMQ URL format.
• AmqpServiceInfo now supports holding a list of URIs for providers that support multiple host connections.

We are pleased to announce the Spring for Apache Hadoop 2.2 RC1 milestone releases. This is the last planned release before the 2.2 GA release in approximately 2 weeks.

The most important changes/enhancements in the Spring for Apache Hadoop 2.2 version are:

• Remove support for running with JDK 6, Java 7 or later is now required
• Improvements to the HDFS writer to support syncable writes and a new timeout option
• Add support for Pivotal HD 3.0
• Update CLoudera CDH 5 to use version 5.3.3
• Update Hortonworks HDP 2.2 version to 2.2.4.0
• Update Kite SDK to version 1.0
• Update Spring project versions to the latest

In the recent years, drastic increases in data volume as well as a greater demand for low latency have led to a radical shift in business requirements and application development methods. In response to these demands, frameworks such as RxJava and high throughput messaging systems such as Kafka have emerged as key building blocks. However, integrating technologies is never easy and Spring XD provides a solution. Through its development model and runtime, Spring XD makes it easy to develop highly scalable data pipelines, and lets you focus on writing and testing business logic vs. integrating and scaling a big data stack. Come and see how easy this can be in this webinar, where we will demonstrate how to build highly scalable data pipelines with RxJava and Kafka, using Spring XD as a platform.

In this article we continue our discussion of how to use Spring Security with Angular JS in a "single page application". Here we show how to write and run unit tests for the client-side code using the Javascript test framework Jasmine. This is the eighth in a series of articles, and you can catch up on the basic building blocks of the application or build it from scratch by reading the first article, or you can just go straight to the source code in Github (the same source code as Part I, but with tests now added). This article actually has very little code using Spring or Spring Security, but…

Dear Spring Community,

I'm pleased to announce the availability of Spring Social 1.1.2.RELEASE. This includes Spring Social's core, web, security, and config modules. This release fixes a dependency issue from last week's 1.1.1.RELEASE.
