Spring Integration IP Extensions

Welcome to the Spring Integration IP Extensions project. It is intended to supplement the spring-integration-ip module with, for example, custom serializers/deserializers.


If you encounter out of memory errors during the build, increase available heap and permgen for Gradle:

GRADLE_OPTS='-XX:MaxPermSize=1024m -Xmx1024m'

To build and install jars into your local Maven cache:

./gradlew install

To build api Javadoc (results will be in build/api):

./gradlew api

To build reference documentation (results will be in build/reference):

./gradlew reference

To build complete distribution including -dist, -docs, and -schema zip files (results will be in build/distributions)

./gradlew dist

Using SpringSource Tool Suite

Gradle projects can be directly imported into STS

Using PLain Eclipse

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.

Using IntelliJ IDEA

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

./gradlew idea

WebSocket Server Demo

This demonstrates how to use the TCP adapters to provide a very lightweight websocket server.

Run WebSocketServerTests as a Java Application (main) and open


in a browser.

Opening the page opens the WebSocket.

Sending 'start' begins sending an incrementing # once per second. 'stop' stops the stream (leaving the socket open), 'start' resumes again. Multiple browser instances get their own sequence #.

Something went wrong with that request. Please try again.
