JMX ObjectName

[manishjs]

Hi,

I am using @ManagedResurce annotation to define the POJO as a MBean and @ManagedAttribute to register attributes.
The bean is a simple POJO with getter & setter.
I specify the objectName & I am able to successfully view the MBean in JConsole.

So far so good..

Now I have a use case where I need to create unique instance of the above mbean and populate it with some statistical data.

I need to register the same pojo multiple time with unique objectName.

How can I pass dynamic value to the objectName in the annotation.
I need to display in jConsole with some logical name i.e the operationName or target method name for which it is holding the value.
For eg

@Component("dataHolder")
@ManagedResource(objectName = "TestJMX:name=JMXDataHolder,type=JMXDataHolder")
public class JMXDataHolder {
...
}

[manishjs]

I have resolved this issue by using programmatic approach by passing the desired objectName while registering the bean. In my POJO which is a managed been I have kept the annotations @ManagedResource (without any options) & @ManagedAttribute as it is.
Before registering the managed bean I am creating & setting the instance of MetadataMBeanInfoAssembler(JMXAttributeSource) so that it can identify the annotation used in the associated object.

Or

You can set the AutodetectMode to AUTODETECT_ASSEMBLER. This will automatically identify the JMX related annotations used in you MBean & expose those operations & attributes.

public void registerSpringWay(JMXDataHolder holder, final ObjectName objectName) {
		try{
			AnnotationMBeanExporter exporter = new AnnotationMBeanExporter();
			
			exporter.setServer(getPlatFormMBeanServer());
			exporter.setAutodetectMode(MBeanExporter.AUTODETECT_ASSEMBLER); 
                        exporter.setAssembler(new MetadataMBeanInfoAssembler(new AnnotationJmxAttributeSource()));
			exporter.setRegistrationBehavior(MBeanExporter.REGISTRATION_IGNORE_EXISTING);			
			exporter.registerManagedResource(holder,objectName);			
			
		}catch(Exception e){			
			e.printStackTrace();
		}
				
	}


	MBeanServer server=null;
	/**
	 * @return
	 */
	private MBeanServer getPlatFormMBeanServer() {
		if(null==server){
			this.server= ManagementFactory.getPlatformMBeanServer();
		}
		
		return server;
	}
