Spring JMX

Spring에서 설정만으로 기본 객체를 MBean으로 등록해 JMX클라이언트가 호출할 수 있게 한다.

	<bean id="exporter" class="org.springframework.jmx.export.MBeanExporter"
	lazy-init="false">
	<property name="autodetect" value="true" />
	<property name="namingStrategy" ref="namingStrategy" />
	<property name="assembler" ref="assembler" />
	</bean>
	<bean id="attributeSource"
	class="org.springframework.jmx.export.annotation.AnnotationJmxAttributeSource" />
	<bean id="assembler"
	class="org.springframework.jmx.export.assembler.MetadataMBeanInfoAssembler">
	<property name="attributeSource" ref="attributeSource" />
	</bean>
	<bean id="namingStrategy"
	class="org.springframework.jmx.export.naming.MetadataNamingStrategy">
	<property name="attributeSource" ref="attributeSource" />
	</bean>
	<bean id="testBean" class="jmxtest.TestBean" />

@ManagedAttribute와 @ManagedOperation 차이는 getter/setter로 처리할 수 있는 속성은  @ManagedAttribute로 어노테이션하고, 그외 getter/setter가 아닌 메소드호출을 위해서는 @ManagedOperation으로 어노테이션한다.

@ManagedOperation
JDK 1.5+ method-level annotation that indicates to expose a given method as JMX operation, corresponding to the ManagedOperation attribute. Only valid when used on a method that is not a JavaBean getter or setter. 

@ManagedAttribute
JDK 1.5+ method-level annotation that indicates to expose a given bean property as JMX attribute, corresponding to the ManagedAttribute attribute. Only valid when used on a JavaBean getter or setter.
