1、mybatis的ehcache依赖:
<!-- mybatis + ehcache start-->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-ehcache</artifactId>
<version>1.0.0</version>
</dependency>
<dependency>
<groupId>org.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>3.0.1</version>
</dependency>
<!-- mybatis + ehcache end-->
2、shiro的ehcache依赖:
<!-- shiro start-->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.2.3</version>
</dependency>
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache-core</artifactId>
<version>2.6.9</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-ehcache</artifactId>
<version>1.2.3</version>
</dependency>
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache-web</artifactId>
<version>2.0.4</version>
</dependency>
<!-- shiro end -->
3、因为两者都有ehcache,所以需要共享ehcache,mybatis配置文件中,加入:
<!-- MyBatis使用ehcache缓存 start -->
<bean id="ehCacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
<property name="configLocation" value="classpath:ehcache.xml"/>
<!-- 和shiro分享缓存 -->
<property name="shared" value="true"></property>
</bean>
<!-- end MyBatis使用ehcache缓存 -->
<!-- shiro缓存管理器 使用Ehcache实现 -->
<bean id="shiroCacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">
<property name="cacheManager" ref="ehCacheManager" />
</bean>
4、作用
1、使mybatis和shiro共享ehcache
2、使同一个查询,只查询一次,第一次查询后,放到ehcache里面,后面直接从缓存取
