Hello World Sample
This is an obvious place to get started. This sample project contains 2 basic sample applications:
- Hello World
- Poller Application
Hello World
The Hello World application demonstrates a simple message flow represented by the diagram below:
Message -> Channel -> ServiceActivator -> QueueChannel
To run the sample simply execute HelloWorldApp in package org.springframework.integration.samples.helloworld. You can also execute that class using the Gradle:
$ gradlew :helloworld:runHelloWorldApp
You should see the following output:
INFO : org.springframework.integration.samples.helloworld.HelloWorldApp - ==> HelloWorldDemo: Hello World
Poller Application
This simple application will print out the current system time twice every 20 seconds.
More specifically, an Inbound Channel Adapter polls for the current system time 2 times every 20 seconds (20000 milliseconds). The resulting message contains as payload the time in milliseconds and the message is sent to a Logging Channel Adapter, which will print the time to the command prompt.
To run the sample simply execute PollerApp in package org.springframework.integration.samples.helloworld. You can also execute that class using the Gradle:
$ gradlew :helloworld:runPollerApp
You should see output like the following:
INFO : org.springframework.integration.samples.helloworld - 1328892135471
INFO : org.springframework.integration.samples.helloworld - 1328892135524
