Spring使用总结(二)：添加缓存管理监控MBean

首先激活Spring的缓存管理，XML配置如下：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:cache="http://www.springframework.org/schema/cache"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd        http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-4.0.xsd">    <cache:annotation-driven cache-manager="cacheManager"/>    <bean id="ehcacheFactory" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">        <property name="configLocation">            <value>classpath:/service-ehcache.xml</value>        </property>    </bean>    <bean id="cacheManager" class="com.yiifaa.base.JmxStaticsEhCacheCacheManager">        <property name="cacheManager">            <ref bean="ehcacheFactory"/>        </property>    </bean></beans>

其次，替换默认的缓存管理器实现，Java代码如下：

package com.yiifaa.base;import net.sf.ehcache.management.ManagementService;import org.springframework.cache.ehcache.EhCacheCacheManager;import org.springframework.jmx.support.JmxUtils;/** * @since 0.1 2012-12-9,下午12:14:04 * 将缓存管理器注册为MBean,可动态观察 * @author  <a href="mailto:ganhuan@legendsec.com">甘焕</a> * @version  0.1  */public class JmxStaticsEhCacheCacheManager extends EhCacheCacheManager {    /* (non-Javadoc)     * @see org.springframework.cache.support.AbstractCacheManager#afterPropertiesSet()     */    @Override    public void afterPropertiesSet() {        super.afterPropertiesSet();        //  注册MBean服务        ManagementService.registerMBeans(this.getCacheManager(), JmxUtils.locateMBeanServer(), false, false, false, true);    }}

现在启动Spring，打开JConsole，就能观测到EhCache的缓存使用情况。
