Accessing MBeans through Proxies

Spring JMX lets you create proxies that re-route calls to MBeans that are registered in a local or remote MBeanServer. These proxies provide you with a standard Java interface, through which you can interact with your MBeans. The following code shows how to configure a proxy for an MBean running in a local MBeanServer:spring-doc.cn

<bean id="proxy" class="org.springframework.jmx.access.MBeanProxyFactoryBean">
	<property name="objectName" value="bean:name=testBean"/>
	<property name="proxyInterface" value="org.springframework.jmx.IJmxTestBean"/>
</bean>

In the preceding example, you can see that a proxy is created for the MBean registered under the ObjectName of bean:name=testBean. The set of interfaces that the proxy implements is controlled by the proxyInterfaces property, and the rules for mapping methods and properties on these interfaces to operations and attributes on the MBean are the same rules used by the InterfaceBasedMBeanInfoAssembler.spring-doc.cn

The MBeanProxyFactoryBean can create a proxy to any MBean that is accessible through an MBeanServerConnection. By default, the local MBeanServer is located and used, but you can override this and provide an MBeanServerConnection that points to a remote MBeanServer to cater for proxies that point to remote MBeans:spring-doc.cn

<bean id="clientConnector"
		class="org.springframework.jmx.support.MBeanServerConnectionFactoryBean">
	<property name="serviceUrl" value="service:jmx:rmi://remotehost:9875"/>
</bean>

<bean id="proxy" class="org.springframework.jmx.access.MBeanProxyFactoryBean">
	<property name="objectName" value="bean:name=testBean"/>
	<property name="proxyInterface" value="org.springframework.jmx.IJmxTestBean"/>
	<property name="server" ref="clientConnector"/>
</bean>

In the preceding example, we create an MBeanServerConnection that points to a remote machine that uses the MBeanServerConnectionFactoryBean. This MBeanServerConnection is then passed to the MBeanProxyFactoryBean through the server property. The proxy that is created forwards all invocations to the MBeanServer through this MBeanServerConnection.spring-doc.cn
