I am using EhCache 1.4.0, Spring 3.0.5 in a web application deployed on Tomcat 6 using JRE 1.6. I am exposing via JMX the L2 cache management, like this:
<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>

I have to allow to clear all the entries in the L2 cache by using the jmxterm tool, like this:
run --bean net.sf.ehcache:type=CacheManager,name=net.sf.ehcache.CacheManager@605df3c5 clearAll
I am aware of jconsole to determine the exact CacheManager
, from the context, but I may not use it for some reasons I won't get into.
So far, so good, but suppose that my JVM (Tomcat server) has 2 applications deployed, both allowing JMX monitoring for EhCache. The names of these two MBeans will be:
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 quite useful when trying to determine which cache to clear.
So my question is: is there any possibility to set the name of each CacheManager, in order to identify exactly which one to use to clear all the entries in the L2 cache ?
Thank you.
I know this was answered long ago, but I think it is easier just to set it in your 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>
