Building on TCP Event publishing in S.I. 3.0, add events for 'HANDSHAKE_COMPLETE' and 'WEBSOCKET_CLOSED'. Update DemoService to consume these events. Change ws.html demo so that the service is started immediately and the 'command' box is now prefilled with 'stop'. When closing the websocket, the DemoService immediately removes the connection from its map, rather than waiting for an exception on the write.
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.
Building
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 complete distribution including -dist and -docs zip files (results will be in build/distributions)
./gradlew dist
IDE Support
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
For more information, please visit the Spring Integration website at: http://www.springsource.org/spring-integration
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
file:///.../spring-integration-extensions/spring-integration-ip-extensions/src/test/java/org/springframework/integration/ip/extensions/sockjs/ws.html
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 #.
Bitcoin Sample
The bitcoin-rt project provides a sample using the Spring Integration IP extensions:
