Spring 使用注解配置使用ehcache

使用ehcache-spring-annotations使得在工程中简单配置即可使用缓存
下载地址：http://code.google.com/p/ehcache-spring-annotations/

 

需要的jar包，首先需要的是我们之前做SpringMVC时的各个Spring的jar包
然后需要把ehcache-spring-annotations-1.2.0文件夹内lib内的，非spring的jar加进去，因为我们已经增加了我们版本的spring
然后还需要动态代理的cglib包

 

SpringMVC的搭建就不再说了，参考
Spring MVC 入门示例 http://cuisuqiang.iteye.com/blog/2042931
Spring MVC Controller配置方式 http://cuisuqiang.iteye.com/blog/2043697

 

在spring主配置文件中配置ehcache注解的使用：

<?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:mvc="http://www.springframework.org/schema/mvc"       xmlns:p="http://www.springframework.org/schema/p"       xmlns:context="http://www.springframework.org/schema/context"       xmlns:aop="http://www.springframework.org/schema/aop"       xmlns:tx="http://www.springframework.org/schema/tx"       xmlns:ehcache="http://ehcache-spring-annotations.googlecode.com/svn/schema/ehcache-spring"       xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsdhttp://ehcache-spring-annotations.googlecode.com/svn/schema/ehcache-spring     http://ehcache-spring-annotations.googlecode.com/svn/schema/ehcache-spring/ehcache-spring-1.1.xsd"><ehcache:annotation-driven cache-manager="ehCacheManager" /><bean id="ehCacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"><property name="configLocation" value="classpath:ehcache.xml"/></bean><bean id="sacheService" class="test.CacheService"></bean></beans>

 

配置缓存配置文件ehcache.xml，改文件放在SRC下：

<?xml version="1.0" encoding="UTF-8"?><ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"updateCheck="false"><diskStore path="java.io.tmpdir" /><defaultCache eternal="false" maxElementsInMemory="1000"overflowToDisk="false" diskPersistent="false" timeToIdleSeconds="0"timeToLiveSeconds="600" memoryStoreEvictionPolicy="LRU" /><cache name="testCache" eternal="false" maxElementsInMemory="100"overflowToDisk="false" diskPersistent="false" timeToIdleSeconds="0"timeToLiveSeconds="300" memoryStoreEvictionPolicy="LRU" /></ehcache>

 

CacheService是示例类，代码如下：

package test;import java.util.Date;import org.springframework.transaction.annotation.Propagation;import org.springframework.transaction.annotation.Transactional;import com.googlecode.ehcache.annotations.Cacheable;import com.googlecode.ehcache.annotations.TriggersRemove;public class CacheService{    @SuppressWarnings("deprecation")@Cacheable(cacheName = "testCache")    public String getName(String code){    System.out.println("查询编号：" + code);        return new Date().toLocaleString() + "-->" + code;    }    @SuppressWarnings("deprecation")    @Transactional(propagation = Propagation.REQUIRED)     public String update(String code){    System.out.println("更新编号：" + code);    return new Date().toLocaleString() + "-->" + code;    }    @TriggersRemove(cacheName="testCache",removeAll=true)    public void flush(){    System.out.println("情况缓存");        System.out.println("Processing testFlushing");    }}

 

改类包含根据参数获取缓存值，更新缓存，情况缓存，都是使用注解标签实现。

 

Action类需要改动一下，代码如下：

package test;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;// http://localhost:8080/spring/hello.do?key=1&code=[e-mail] class HelloController{private CacheService sacheService;@SuppressWarnings("deprecation")@RequestMapping("/hello.do")public String hello(HttpServletRequest request,HttpServletResponse response){String key = request.getParameter("key");if("1".equals(key)){request.setAttribute("message", sacheService.getName(request.getParameter("code")));}else if("2".equals(key)){request.setAttribute("message", sacheService.update(request.getParameter("code")));}else{sacheService.flush();request.setAttribute("message", sacheService.getName(request.getParameter("code")));}return "hello";}public CacheService getSacheService() {return sacheService;}@Autowiredpublic void setSacheService(CacheService sacheService) {this.sacheService = sacheService;}}

 

根据key做不同的操作，然后分别访问以下几个路径，为了方便看效果和学习，我把工程代码放到了附件：
第一次没有缓存
http://localhost:8080/spring/hello.do?key=1&code=java
读取缓存
http://localhost:8080/spring/hello.do?key=1&code=java
更新缓存
http://localhost:8080/spring/hello.do?key=2&code=java
读取最新缓存
http://localhost:8080/spring/hello.do?key=1&code=java
情况缓存
http://localhost:8080/spring/hello.do?key=3
