Spring Cache集成EHCache

EHCache支持内存和磁盘的缓存,支持LRU、LFU和FIFO多种淘汰算法,支持分布式的Cache,可以作为Hibernate的缓存插件。同时它也能提供基于Filter的Cache,该Filter可以缓存响应的内容并采用Gzip压缩提高响应速度。

可以通过spring集成提供缓存管理,spring为ehcache提供了如下的实现类:
EhCacheCache实现Cache接口
EhCacheCacheManager实现CacheManager接口
EhCache工厂管理类
EhCacheFactoryBean
EhCacheManagerFactoryBean
1.引入ehcache jar包


<dependency>
   <groupId>net.sf.ehcache</groupId>
   <artifactId>ehcache-core</artifactId>
   <version>2.6.6</version>
  </dependency>
2.ehcache配置


<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="true"
 monitoring="autodetect">
 <!-- <diskStore path="java.io.tmpdir" /> -->
 <diskStore path="C:/cache_tmpdir" />
 
 <defaultCache maxElementsInMemory="10000" eternal="false"
  timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true"
  maxElementsOnDisk="10000000" diskPersistent="false"
  diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU" />

 <cache name="userCache" maxElementsInMemory="10000"
  maxElementsOnDisk="1000" eternal="false" overflowToDisk="true"
  diskSpoolBufferSizeMB="20" timeToIdleSeconds="300" timeToLiveSeconds="600"
  memoryStoreEvictionPolicy="LFU" />
 
</ehcache>
3.spring配置


<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"
 xmlns:p="http://www.springframework.org/schema/p"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/cache
http://www.springframework.org/schema/cache/spring-cache.xsd">
 <!-- 启用缓存注解功能,这个是必须的,否则注解不会生效,另外,该注解一定要声明在spring主配置文件中才会生效 -->
 <cache:annotation-driven cache-manager="cacheManager" />

 <bean id="userService" class="org.springframework.cache.demo.UserService" />

 <!-- cacheManager工厂类,指定ehcache.xml的位置 -->
 <bean id="cacheManagerFactory"
  class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
  p:configLocation="classpath:ehcache.xml" />

 <!-- 声明cacheManager -->
 <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager"
  p:cacheManager-ref="cacheManagerFactory" />
</beans>
