Spring Integration 2.1 is now GA |
|
Spring Integration 2.1 has been released! You can download it here or configure your Maven POM. This version is the result of more than one full year of work, and the team has resolved hundreds of issues since Spring Integration 2.0 was released. Interestingly, it has been 4 years and a few days since the very first public release of Spring Integration (0.5, released on Jan 3rd 2008). In this post, I simply want to provide a quick overview of the main new features of 2.1.
RabbitMQ/AMQP support
In the 'spring-integration-amqp' module, we have Channel Adapters for one-way messaging as well as Gateways for request/reply. The adapters and gateways can be used for inbound and/or outbound integration with a RabbitMQ broker. We also have AMQP-backed Message Channel implementations – both point-to-point and publish/subscribe – that can be used anywhere in the middle of a flow. For more information, see this section of the reference manual.
GemFire support
In the 'spring-integration-gemfire' module, we have inbound Channel Adapters for continuous queries as well as simple cache-listening. We also provide an outbound Channel Adapter for writing to a cache region. If you want to use GemFire for persistence behind an Aggregator, Claim Check, or buffering Message Channel, you can configure a GemFire Message Store. For more information, see this section of the reference manual.
Redis support
In the 'spring-integration-redis' module, we have inbound and outbound Channel Adapters that rely on Redis' pub/sub functionality. Also, you can configure a Redis-backed Message Store for persistence behind an Aggregator, Claim Check, or buffering Message Channel. For more information, see this section of the reference manual.
MongoDB support
In the 'spring-integration-mongodb' module, we have another Message Store implementation that you can use behind an Aggregator, Claim Check, or buffering Message Channel. For more information, see this section of the reference manual.
JSR-223 scripting support
In the 'spring-integration-scripting' module, we provide the functionality necessary to support the use of a variety of scripting languages for any of the core EIP components (filters, splitters, routers, transformers, etc). Supported languages include: Groovy, Ruby/JRuby, Python/Jython, and JavaScript. Like the Groovy support that existed since version 2.0, these scripts can be dynamically refreshed at runtime. For more information, see this section of the reference manual.
Stored Procedure support
In the 'spring-integration-jdbc' module, we have added Stored Procedure adapters along side the existing adapters that support simple select/insert/update operations. For more information, see this section of the reference manual.
Spring Resource abstraction support
In the 'spring-integration-core' module, we have added a new inbound Channel Adapter that operates against an instance of Spring's Resource abstraction. That provides flexibility across a number of underlying resources, such as files, classpath resources, or any resource that can be located via a URL. For more information, see this section of the reference manual.
Payload Enricher
In the 'spring-integration-core' module, we have added an 'enricher' component that allows for a message flow to be "called" from within another flow so that the result of that flow can be used to enrich the payload of a Message. It complements the existing header-enricher component. For more information, see this section of the reference manual.
FTP and SFTP outbound gateways
In the 'spring-integration-ftp' and 'spring-integration-sftp' modules, we have added outbound gateway adapters to support request/reply operations in addition to the existing one-way channel adapters. For more information, see this section for FTP and this section for SFTP.
Migrating from Spring Integration 2.0
If you plan to upgrade an application from Spring Integration version 2.0, then please refer to our migration guide. We will be updating that document as necessary, so please send us feedback if you do encounter any issues that are not yet mentioned within that guide.
Summary
As you can see, we have been quite busy. In addition to the new functionality described above, there are a number of improvements and refactoring. You may want to start with this section of the reference manual where you will find more information about those other improvements in addition to the features mentioned in this post. Also, be sure to checkout the Spring Integration Samples on github.
As always, we welcome your feedback. Please join the discussion in the Spring Integration Forum, and visit the Spring Integration Homepage for additional references and links to the source code, issue tracker, blogs, and more.

What has Spring delivered really? This kind of exception
x.x.x.x.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [x.y.z.IXXXXManagerFactory] is defined: No beans of type x.y.z.IXXXXManagerFactory; owner=com.hiddenduetoNDA.springframework.context.support.GenericApplicationContext@1a54c73: display name [com.hidden.....core.repackaged.springframework.context.support.GenericApplicationContext@1a54c73];
Thanks to Spring I have yet another layer of . .. . lookup-code!!!! to navigate. And here's a big shout-out to BEA for mangling EJB-annotations by using Spring to "implement" them.
Ever picked apart an EAR 80Mb and expanded it and gone through thousands of entries to find why the class cannot be loaded? I have!!!! and at the end, still no reason!!!!
