How to set net.sf.ehcache.CacheManager name to monitor JMX?

I am using EhCache 1.4.0, Spring 3.0.5 in a web application deployed on Tomcat 6 using JRE 1.6. I look through JMX L2 cache management, for example:

<bean id="mbeanServer" class="org.springframework.jmx.support.MBeanServerFactoryBean"> <property name="locateExistingServerIfPossible" value="true" /> </bean> <util:property-path id="hibernateCacheProvider" path="sessionFactory.settings.cacheProvider" /> <bean id="hibernateEhCacheManager" class="com.mycompany.spring.beans.factory.config.UnaccessibleFieldRetrievingFactoryBean"> <property name="targetObject" ref="hibernateCacheProvider" /> <property name="targetField" value="manager" /> <property name="makeInstanceFieldVisible" value="true" /> </bean> <bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean"> <description>The cacheManager configuration.</description> <property name="targetClass" value="net.sf.ehcache.management.ManagementService" /> <property name="staticMethod" value="net.sf.ehcache.management.ManagementService.registerMBeans" /> <property name="arguments"> <list> <ref bean="hibernateEhCacheManager" /> <ref bean="mbeanServer" /> <value type="boolean">true</value> <value type="boolean">true</value> <value type="boolean">true</value> <value type="boolean">true</value> </list> </property> </bean> <bean class="org.springframework.jmx.export.annotation.AnnotationMBeanExporter"> <property name="server" ref="mbeanServer" /> <property name="beans"> <map> <entry key="Hibernate:type=statistics,application=applicationOne"> <bean class="org.hibernate.jmx.StatisticsService"> <property name="statisticsEnabled" value="true" /> <property name="sessionFactory" ref="sessionFactory" /> </bean> </entry> </map> </property> </bean> <bean id="hbm.properties" class="org.springframework.beans.factory.config.PropertiesFactoryBean"> <property name="properties"> <props> <prop key="hibernate.show_sql">false</prop> <prop key="hibernate.generate_statistics">false</prop> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</prop> <prop key="hibernate.cache.use_query_cache">true</prop> <prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop> <prop key="hibernate.cache.provider_configuration_file_resource_path">applicationOne-web/ehcache.xml</prop> <prop key="hibernate.cache.query_cache_factory">org.hibernate.cache.StandardQueryCacheFactory</prop> </props> </property> </bean>

I must allow to clear all entries in the L2 cache using the jmxterm tool, for example:

 run --bean net.sf.ehcache:type=CacheManager, name=net.sf.ehcache.CacheManager@605df3c5 clearAll

I know jconsole to determine the exact CacheManager , out of context, but I cannot use it for some reason, I will not get in.

So far, so good, but suppose my JVM (Tomcat server) has 2 applications deployed, which allows JMX monitoring for EhCache. The names of these two MBeans will be as follows:

 net.sf.ehcache:type=CacheManager, name=net.sf.ehcache.CacheManager@605df3c5 net.sf.ehcache:type=CacheManager, name=net.sf.ehcache.CacheManager@49ff3459

As you can see, they are not very useful when trying to determine which cache is being cleared.

So my question is: is it possible to set the name of each CacheManager to determine exactly which one to use to clear all entries in the L2 cache?

Thanks.

Once hibernateEhCacheManager is available, you can call its methods (by setting the inclusion) using the following bean definition. Usually this should do the trick renaming the CacheManager.

  <bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean"> <property name="targetObject"> <ref local="hibernateEhCacheManager"/> </property> <property name="targetMethod"> <value>setName</value> </property> <property name="arguments" value="<the_desired_name>"/> </bean>

I know this was given a long time ago, but I think it’s easier to just install it in my ehcache configuration file (applicationOne-web / ehcache.xml).

 <ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="false" monitoring="autodetect" dynamicConfig="true" name="MY_CACHE_MANAGER_NAME"> ... </ehcache>
