1.添加依赖。除SSM所需的包外,还需要添加的包为 mybatis-ehcache.jar、ehcache-spring-annotations.jar;maven坐标如下:
<!--Mybatis-ehcache-->
<dependency>
<groupId>org.mybatis.caches</groupId>
<artifactId>mybatis-ehcache</artifactId>
<version>1.0.3</version>
</dependency>
<!--ehcache-spring-annotations-->
<dependency>
<groupId>com.googlecode.ehcache-spring-annotations</groupId>
<artifactId>ehcache-spring-annotations</artifactId>
<version>1.2.0</version>
</dependency>
2.echache配置文件,如下:
ehcache.xml
<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">
<diskStore path="java.io.tmpdir"/>
<defaultCache
maxElementsInMemory="3000"
eternal="false"
timeToIdleSeconds="3600"
timeToLiveSeconds="3600"
overflowToDisk="true"
diskPersistent="false"
diskExpiryThreadIntervalSeconds="100"
memoryStoreEvictionPolicy="LRU"/>
</ehcache>
applicationContext-echache.xml
<?xml version="1.0" encoding="UTF-8"?>
<!-- /** * * 缓存配置 * * */ -->
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ehcache="http://ehcache-spring-annotations.googlecode.com/svn/schema/ehcache-spring"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://ehcache-spring-annotations.googlecode.com/svn/schema/ehcache-spring
http://ehcache-spring-annotations.googlecode.com/svn/schema/ehcache-spring/ehcache-spring-1.1.xsd">
<ehcache:annotation-driven cache-manager="ehCacheManager" />
<bean id="ehCacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
<property name="configLocation" value="classpath:ehcache/ehcache.xml" />
<property name="shared" value="true"/>
</bean>
</beans>
3.将echache配置文件加载到spring-mvc.xml中
<!--加载ehcache缓存-->
<import resource="classpath:ehcache/applicationContext-ehcache.xml"/>
4.在mybatis mapper.xml中配置,比如SysUserMapper.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.springmvc.mapper.system.SysUserMapper">
<!-- 以下两个<cache>标签二选一,第一个可以输出日志,第二个不输出日志 -->
<cache type="org.mybatis.caches.ehcache.EhcacheCache" />
<!--<cache type="org.mybatis.caches.ehcache.LoggingEhcache"/>-->
</mapper>
