Spring Integration provides an extension of the Spring programming model to support the well-known Enterprise Integration Patterns (EIP)

readme.txt
============================== Spring Integration =============================
To check out the project and build from source, do the following:

 git clone --recursive git://git.springsource.org/spring-integration/spring-integration.git
 cd spring-integration
 ./gradlew build

Note: the --recursive switch above is important, as spring-integration uses
git submodules, which must themselves be cloned and initialized. If --recursive
is omitted, doing so becomes a multi-step process.

If you encounter heap space errors during the build, increase the heap size for
gradle:
 GRADLE_OPTS="-Xmx1024m"

-------------------------------------------------------------------------------
To generate Eclipse metadata (.classpath and .project files), do the following:

 ./gradlew eclipse

Once complete, you may then import the projects into Eclipse as usual:

 File -> Import -> Existing projects into workspace

Browse to the 'spring-integration' root directory. All projects should import
free of errors.

-------------------------------------------------------------------------------
To generate IDEA metadata (.iml and .ipr files), do the following:

 ./gradlew idea

-------------------------------------------------------------------------------
To build the JavaDoc, do the following from within the root directory:

 ./gradlew :docs:api

The result will be available in 'docs/build/api'.

###### OSGI Notes ######

1. Dependency on Third Party Bundles
    Some adapters depend on third party libraries (bundles).
    Spring hosts the Enterprise Bundle Repository (EBR) at
        https://ebr.springsource.com/repository/app/, where you can download
        many third-party JARs as valid OSGi bundles.
    If a particular bundle is not available in Spring's EBR, there are tools
       that can convert a regular JAR to a bundle JAR. One of them is Bundlor
       http://www.springsource.org/bundlor which can auto-generate an OSGi
       MANIFEST.MF as part of standard project lifecycle or simply convert a
       non-bundle JAR to a bundle JAR.
2. Boot delegation
    Some adapters depend on extension packages that are available to the boot
    class loader. As a case in point, the Feed Adapter depends on
    com.sun.syndication.feed. Since by default OSGi only loads java.* from the
    boot class loader, other packages that must be loaded from the boot class
    loader can therefore be specified with the
    'org.osgi.framework.bootdelegation' System property.
    For example:
        org.osgi.framework.bootdelegation=com.sun.*,org.w3c.*. . . .
