spring注解方式实现Cache的简单Demo

第一步：加入所依赖的jar包

<!--Ehcache-->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.21</version>
</dependency>
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache-core</artifactId>
<version>2.6.6</version>
</dependency>
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>2.8.3</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>${org.springframework-version}</version>
</dependency>
<dependency>
<groupId>com.googlecode.ehcache-spring-annotations</groupId>
<artifactId>ehcache-spring-annotations</artifactId>
<version>1.2.0</version>
</dependency>

第二步： 加入ehcache.xml和ehcache.xsd配置文件

ehcache.xml配置文件如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="classpath:/ehcache.xsd" updateCheck="true" monitoring="autodetect"
dynamicConfig="true">
<diskStore path="java.io.tmpdir/" />
<!--
diskStore path:用来配置磁盘缓存使用的物理路径
name:   缓存名称,cache的唯一标识(ehcache会把这个cache放到HashMap里)
eternal="false"   元素是否永恒,如果是就永不过期(必须设置)
maxElementsOnDisk====磁盘缓存中最多可以存放的元素数量,0表示无穷大
maxElementsInMemory="1000" 内存缓存中最多可以存放的元素数量(必须设置)
timeToIdleSeconds="0"   导致元素过期的访问间隔(秒为单位). 0表示可以永远空闲,默认为0
timeToLiveSeconds="600" 元素在缓存里存在的时间(秒为单位). 0 表示永远存在不过期
overflowToDisk="false"  当缓存达到maxElementsInMemory值是,是否允许溢出到磁盘(必须设置)
diskPersistent="false"  磁盘缓存在VM重新启动时是否保持(默认为false)
diskExpiryThreadIntervalSeconds="100" 磁盘失效线程运行时间间隔,默认是120秒
memoryStoreEvictionPolicy="LFU" 内存存储与释放策略.当达到maxElementsInMemory时
共有三种策略,分别为LRU(最近最少使用,最久未使用算法，使用时间距离现在最久的那个被移除；)、LFU(最常用的,最近最少使用算法，一定时间段内使用次数（频率）最少的那个被移除)、FIFO(先进先出)默认使用"最近使用"策略
-->
<defaultCache
eternal="false"
maxElementsInMemory="3000"
timeToIdleSeconds="3600"
timeToLiveSeconds="0"
overflowToDisk="true"
diskPersistent="false"
diskExpiryThreadIntervalSeconds="100"
memoryStoreEvictionPolicy="LRU"/>

<cache name="propConfigCache"
eternal="false"
maxElementsInMemory="3000"
overflowToDisk="true"
timeToIdleSeconds="0"
timeToLiveSeconds="1440"
memoryStoreEvictionPolicy="LFU"/>

<cache name="workTimeCache"
eternal="false"
maxElementsInMemory="3000"
overflowToDisk="true"
timeToIdleSeconds="0"
timeToLiveSeconds="1440"
memoryStoreEvictionPolicy="LFU"/>

<cache name="threeInOneCache"
eternal="false"
maxElementsInMemory="3000"
overflowToDisk="true"
timeToIdleSeconds="0"
timeToLiveSeconds="1440"
memoryStoreEvictionPolicy="LFU"/>

<cache name="transferCache"
eternal="false"
maxElementsInMemory="1000"
overflowToDisk="true"
timeToIdleSeconds="0"
timeToLiveSeconds="1440"
memoryStoreEvictionPolicy="LFU"/>

<cache name="threeInOneFavCache"
eternal="false"
maxElementsInMemory="3000"
overflowToDisk="true"
timeToIdleSeconds="0"
timeToLiveSeconds="1440"
memoryStoreEvictionPolicy="LFU"/>

<cache name="reserveTimeCache"
eternal="false"
maxElementsInMemory="3000"
overflowToDisk="true"
timeToIdleSeconds="0"
timeToLiveSeconds="1440"
memoryStoreEvictionPolicy="LFU"/>

<cache name="mqServerNameCache"
eternal="false"
maxElementsInMemory="3000"
overflowToDisk="true"
timeToIdleSeconds="0"
timeToLiveSeconds="1440"
memoryStoreEvictionPolicy="LFU"/>

<cache name="schWorkTimeCache"
eternal="false"
maxElementsInMemory="3000"
overflowToDisk="true"
timeToIdleSeconds="0"
timeToLiveSeconds="1440"
memoryStoreEvictionPolicy="LFU"/>

</ehcache>

ehcache.xsd的配置文件如下所示：

第四步：在xxx-service.xml文件中加入如下配置：

<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"

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

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

第5步：在需要缓存的service或者biz的方法上加上对应的注：

@Cacheable(value = "propConfigCache",key = "#dateStr+'skynet'")
