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"       xmlns:cache="http://www.springframework.org/schema/cache"       xmlns:util="http://www.springframework.org/schema/util" xmlns:aop="http://www.springframework.org/schema/aop"       xsi:schemaLocation="    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd        http://www.springframework.org/schema/cache        http://www.springframework.org/schema/cache/spring-cache-3.1.xsd        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.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"/>    <!-- 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'")
