Exposing MBeans with Spring

Published by Gilles at 9:21 pm under J2EE, Java, Spring

The core class in Spring's framework is the MBeanExporter. This class is responsible for taking your beans and registering them with a MBeanServer.

Add an MBeanExporter bean in your applicationContext: (for my part, I created a separate applicationContext-.xml)

A first approach is to add the beans you want to be managed as key/value of the beans/map property:

PLAIN TEXT
XML:
  1. <bean id="exporter" class="org.springframework..export.MBeanExporter" lazy-init="false">
  2. <property name="beans">
  3. map>
  4. <entry key="bean:name=testBean1" value-ref="testBean"/>
  5. </map></property>
  6. </bean>
  7. <bean id="testBean" class="mypackage.MyClass"/>

To register your exposed MBeans, you can either create a new MBeanServer or reuse an existing one. I choosed to reuse an existing one.

PLAIN TEXT
XML:
  1. <bean id="mbeanServer" class="org.springframework..support.MBeanServerFactoryBean">
  2. <!-- indicate to first look for a server -->
  3. <property name="locateExistingServerIfPossible" value="true"/>
  4. </bean>

    Hello, I found your post about the Spring mbeans in the WebSphere 6.1. I am new to Spring and JMX and looking for a step by step guide to register and calling by wsadmin some Spring’s mbeans provided by the app developer. I read your post and do understand the websphere naming strategy but where do I need to place this class WebsphereNamingStrategy ?

    Hello Mark,
    You can place your WebsphereNamingStrategy class where you want. For my part, I place it in an “util” package…
    Cheers,

    Hello Gilles,
    Thanks a lot for a quick response. I just have one question if there is any possibility to enable the Spring’s mbean in WAS 6.1 without adding any new code to the project ? I do not have the source code and do not want to extend the EAR file.

    excellent info, thanks!
    was trying to get this running on websphere and also figured out that websphere changes the objectnames of the mbeans..your sources saved a lot of time for me yeehaa :-)
