This example demonstrates the following aspects of the JMX support available with Spring Integration:
1. JMX Attribute Polling Channel
2. JMX Operation Invoking Channel Adapter
StopWatch is a Managed Bean. It is bootstraped and deployed using annotation support (@Component, @ManagedResource)
and component scanning functionality provided by Spring JMX. Internally StopWatch simply runs a task that increments the
value of its 'seconds' attribute by 1 every second.
JMX Attribute Polling Channel Adapter simply polls a managed attribute 'Seconds' of the StopWatch MBean identified by the 'org.springframework.integration.samples.jmx:type=StopWatch,name=stopWatch' name and sends its value to a 'seconds' channel.
The interesting this is that 'seconds' channel is a publish-subscribe-channel and has two subscribers;
- Stdout Channel Adapter which prints the value of the polled attribute to the console;
- Filter which essentially waits till payload value is 10;
Once the payload value is 10 filter sends the Message to a 'reset' channel which is represented as JMX Operation Invoking Channel Adapter
which simply invokes 'reset' operation on the same StopWatch MBean resetting 'Seconds' attribute value back to 1 and the process repeats.
To run samples simply execute the 3 test cases located in the org.springframework.integration.samples.filecopy package
You will see the output similar to this which will loop for ~ 20 sec:
