一：spring整合ehcache
1、spring整合的ehcache是2.10.x版，jar包要對。

    <!--ehcache -->
    <dependency>
      <groupId>net.sf.ehcache</groupId>
      <artifactId>ehcache</artifactId>
      <version>2.10.0</version>
    </dependency>

2、spring 的xml配置

    <bean id="cache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
        <property name="configLocation" value="classpath:ehcache.xml" />
    </bean>
    <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
        <property name="cacheManager" ref="cache" />
    </bean>
    <cache:annotation-driven cache-manager="cacheManager"/>
 

3、ehcaceh的xml配置
該配置檔案可以在net.sf.ehcache jar包下找到

ehcache.xml詳細配置參考

<?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" dynamicConfig="true">

    <diskStore path="java.io.tmpdir"/>

    <defaultCache
            maxEntriesLocalHeap="1000"
            eternal="false"
            overflowToDisk="false"
            timeToIdleSeconds="120"
            timeToLiveSeconds="120"
            diskSpoolBufferSizeMB="30"
            maxEntriesLocalDisk="1000000"
            diskExpiryThreadIntervalSeconds="120"
            memoryStoreEvictionPolicy="LRU">
        <persistence strategy="localTempSwap"/>
    </defaultCache>

    <cache name="demoCache"
           maxEntriesLocalHeap="1000"
           maxEntriesLocalDisk="100"
           eternal="false"
           diskSpoolBufferSizeMB="30"
           timeToIdleSeconds="300"
           timeToLiveSeconds="600"
           memoryStoreEvictionPolicy="LFU"
           transactionalMode="off">
        <persistence strategy="localTempSwap"/>
    </cache>


</ehcache>

 

4、spring整合ehcache註解的使用demo

    @Cacheable(value="demoCache",key="#userName")
    public User findUserByUserName(String userName){
        System.out.println("--------- find user name -----------");
        return new User("ke","123654","cccp");
    }

    @CacheEvict(value = "demoCache",key = "#userName")
    public User removeName(String userName){
        System.out.println("--------- delete user name -----------");
        return new User("kexq","123654","2009");
    }
 

註解說明：
（1）@Cacheable(value=“demoCache”,key="#userName",condition="")
value：cacheName 不可為空；在ehcache.xml檔案中必須存在的cacheNme
key：springEL表示式編寫
condition：限制條件
（2）@CacheEvict
去除快取
（3）@CachePut
不管對應快取是否存在，都執行方法體，並且將返回的內容寫入快取
（4）@CacheConfig(value=“cacheName”)
類級別的註解，若類中使用快取是同一個，可以配置在此註解中
5、demoTest

    @Resource
    private LoginService loginService;

    @RequestMapping("index.do")
    public String index(){
        //第一次呼叫時快取，第二次呼叫直接取快取
        loginService.findUserByUserName("ke");
        loginService.findUserByUserName("ke");

        loginService.removeName("ke");
        // 刪除後再次呼叫時，再次快取
        System.out.println(loginService.findUserByUserName("ke"));

        return "index";
    }
