This section details the compatible Java and Spring Framework versions.

Compatible Java Versions

For Spring Integration 5.5.x, the minimum compatible Java version is Java SE 8. Older versions of Java are not supported.

Compatible Versions of the Spring Framework

Spring Integration 5.5.x requires Spring Framework 5.3 or later.

Code Conventions

Spring Framework 2.0 introduced support for namespaces, which simplifies the XML configuration of the application context and lets Spring Integration provide broad namespace support.

In this reference guide, the int namespace prefix is used for Spring Integration’s core namespace support. Each Spring Integration adapter type (also called a module) provides its own namespace, which is configured by using the following convention:

The following example shows the int, int-event, and int-stream namespaces in use:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=""

For a detailed explanation regarding Spring Integration’s namespace support, see Namespace Support.

The namespace prefix can be freely chosen. You may even choose not to use any namespace prefixes at all. Therefore, you should apply the convention that best suits your application. Be aware, though, that SpringSource Tool Suite™ (STS) uses the same namespace conventions for Spring Integration as used in this reference guide.

Conventions in This Guide

In some cases, to aid formatting when specifying long fully qualified class names, we shorten org.springframework to o.s and org.springframework.integration to o.s.i, such as with o.s.i.transaction.TransactionSynchronizationFactory.
