1. What's new in Spring Integration 2.2?

This chapter provides an overview of the new features and improvements that have been introduced with Spring Integration 2.2 If you are interested in even more detail, please take a look at the Issue Tracker tickets that were resolved as part of the 2.2 development process:

1.1 General

1.1.1 Spring 3.1

Spring Integration now uses Spring 3.1.

1.1.2 Outbound Gateways

The XML Namespace support adds the reply-timeout attribute to the following Outbound Gateways:

  • Amqp Outbound Gateway
  • File Outbound Gateway
  • Ftp Outbound Gateway
  • Sftp Outbound Gateway
  • Ws Outbound Gateway

1.1.3 Spring-AMQP 1.1

Spring Integration now uses Spring AMQP 1.1. This enables several features to be used within a Spring Integration application, including...

  • A fixed reply queue for the outbound gateway
  • HA (mirrored) queues
  • Publisher Confirms
  • Returned Messages
  • Support for Dead Letter Exchanges/Dead Letter Queues

1.1.4 JDBC Adapter - Stored Procedures Components

SpEL Support

When using the Stored Procedure components of the Spring Integration JDBC Adapter, you can now provide Stored Procedure Names or Stored Function Names using Spring Expression Language (SpEL).

This allows you to specify the Stored Procedures to be invoked at runtime. For example, you can provide Stored Procedure names that you would like to execute via Message Headers. For more information please see Section 17.5, “Stored Procedures”.

JMX Support

The Stored Procedure components now provide basic JMX support, exposing some of their properties as MBeans:

  • Stored Procedure Name
  • Stored Procedure Name Expression
  • JdbcCallOperations Cache Statistics

1.1.5 JDBC Adapter - Outbound Gateway

When using the JDBC Outbound Gateway, the update query is no longer mandatory. You can now provide solely a select query using the request message as a source of parameters.

1.1.6 File Adapter - Improved File Overwrite/Append Handling

When using the File Oubound Channel Adapter or the File Outbound Gateway, a new mode property was added. Prior to Spring Integration 2.2, target files were replaced when they existed. Now you can specify the following options:

  • REPLACE (Default)
  • FAIL

For more information please see Section 12.3.2, “Dealing with Existing Destination Files”.

1.1.7 Transaction Synchronization

When running from a transactional poller, mail inbound adapters can be configured to update the mailbox only if the transaction commits.

1.1.8 Orderly Shutdown

A method stopActiveComponents() has been added to the IntegrationMBeanExporter. This allows a Spring Integration application to be shut down in an orderly manner, disallowing new inbound messages to certain adapters and waiting for some time to allow in-flight messages to complete.

1.2 New Components

1.2.1 JPA Endpoints

Spring Integration now includes components for the Java Persistence API (JPA) for retrieving and persisting JPA entity objects. The JPA Adapter includes the following components:

1.3 Framework Refactoring
