<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC
          "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN"
          "http://struts.apache.org/dtds/struts-config_1_3.dtd">
<struts-config>

	<!-- 配置formbean -->

		 <!-- 最大空闲值.当经过一个高峰时间后,连接池可以慢慢将已经用不到的连接释放一部分,一直减少到maxIdle为止 -->
		 <property name="maxIdle" value="2"/>
		 <!--  最小空闲值.当空闲的连接数少于阀值时,连接池就会预申请一些连接,以避免洪峰来时再申请而造成的性能开销 -->
		 <property name="minIdle" value="1"/>
 	</bean>
 	
	<!-- 使用Spring提供的sessionFactory 指定它要使用的数据源以及数据库相关信息 -->
	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

		      </value>
	    </property>
	</bean>

	<!-- 配置事务管理器指定其作用的sessionFactory 这样就把事务交给Spring去处理,减轻程序员负担-->
	<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
	  	<property name="sessionFactory" ref="sessionFactory"/>
	</bean>
	
	<!-- aop的配置 -->
	<aop:config>

</beans>

 

 

4.ehcache.xml配置如下:

 

<?xml version="1.0" encoding="UTF-8"?>
<!-- 
    defaultCache节点为缺省的缓存策略
     maxElementsInMemory 内存中最大允许存在的对象数量
     eternal 设置缓存中的对象是否永远不过期
     overflowToDisk 把溢出的对象存放到硬盘上
     timeToIdleSeconds 指定缓存对象空闲多长时间就过期,过期的对象会被清除掉
     timeToLiveSeconds 指定缓存对象总的存活时间
     diskPersistent 当jvm结束是是否持久化对象
     diskExpiryThreadIntervalSeconds 指定专门用于清除过期对象的监听线程的轮询时间
 -->
<ehcache>
    <diskStore path="D:\cache"/>
    <defaultCache maxElementsInMemory="1000" eternal="false" overflowToDisk="true"
        timeToIdleSeconds="120"
        timeToLiveSeconds="180"
        diskPersistent="false"
        diskExpiryThreadIntervalSeconds="60"/>
        
	<cache name="cn.itcast.bean.Person" maxElementsInMemory="100" eternal="false"

5.Person.hbm.xml配置如下:

    <class name="Person" table="person">
   		<cache usage="read-write" region="cn.itcast.bean.Person"/>
