1. 添加ehcache的jar依赖
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<properties>

<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>2.8.2</version>
</dependency>
</dependencies>
</project>
2.添加ehcache配置文件ehcache-setting.xml
<?xml version="1.0" encoding="UTF-8"?>
<ehcache>
<!-- 指定一个文件目录,当EhCache把数据写到硬盘上时,将把数据写到这个文件目录下 -->
<diskStore path="java.io.tmpdir"/>
<!-- 设定缓存的默认数据过期策略 -->
<defaultCache
maxElementsInMemory="10000"
eternal="false"
overflowToDisk="true"
timeToIdleSeconds="10"
timeToLiveSeconds="20"
diskPersistent="false"
diskExpiryThreadIntervalSeconds="120"/>
<cache name="cacheTest"
maxElementsInMemory="1000"
eternal="false"
overflowToDisk="true"
timeToIdleSeconds="10"
timeToLiveSeconds="20"/>
</ehcache>
3、spring配置文件application.xml
<?xml version="1.0" encoding="UTF-8"?>
<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:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/cache
http://www.springframework.org/schema/cache/spring-cache-3.1.xsd">
<!-- 自动扫描注解的bean -->
<context:component-scan base-package="com.xu.service" />
<cache:annotation-driven cache-manager="cacheManager" />
<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
<property name="cacheManager" ref="ehcache"></property>
</bean>
<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
<property name="configLocation" value="classpath:ehcache-setting.xml"></property>
</bean>
</beans>
4、EhCacheTestService接口
package com.xu.service;
public interface EhCacheTestService {
public String getTimestamp(String param);
}
5、EhCacheTestService接口实现
package com.xu.service.impl;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.stereotype.Service;
import com.luo.service.EhCacheTestService;
@Service
public class EhCacheTestServiceImpl implements EhCacheTestService {
@Cacheable(value="cacheTest",key="#param")
public String getTimestamp(String param) {
Long timestamp = System.currentTimeMillis();
return timestamp.toString();
}
}
这里注解中value=”cacheTest”与ehcache-setting.xml中的cache名称属性值一致。
6、单元测试类
package com.xu.test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
//指定bean注入的配置文件
@ContextConfiguration(locations = { "classpath:application.xml" })
//使用标准的JUnit @RunWith注释来告诉JUnit使用Spring TestRunner
@RunWith(SpringJUnit4ClassRunner.class)
public class SpringTestCase extends AbstractJUnit4SpringContextTests {
}
package com.xu.test;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import com.luo.baseTest.SpringTestCase;
public class EhCacheTestServiceTest extends SpringTestCase {
@Autowired
private EhCacheTestService ehCacheTestService;
@Test
public void getTimestampTest() throws InterruptedException{
System.out.println("第一次调用:" + ehCacheTestService.getTimestamp("param"));
Thread.sleep(2000);
System.out.println("2秒之后调用:" + ehCacheTestService.getTimestamp("param"));
Thread.sleep(11000);
System.out.println("再过11秒之后调用:" + ehCacheTestService.getTimestamp("param"));
}
}
