一：详细配置步骤

     1，添加ehcache.xml文件

      将ehcache.xml文件添加到src路径下面。ehcache.xml文件内容如下



[html] ​​view plain​​ ​​copy​​

​​print​​​​?​​

  2. <ehcache>  
  3.     <diskStore path="java.io.tempdir" />  
  4.     <defaultCache maxElementsInMemory="1000" eternal="false"  
  5.         timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true" />  
  6.     <cache name="ehcacheName" maxElementsInMemory="10000"  
  7.         eternal="false" timeToIdleSeconds="300000" timeToLiveSeconds="600000"  
  8.         overflowToDisk="true" />  
  9. </ehcache>  
<ehcache>
  <diskStore path="java.io.tempdir" />
  <defaultCache maxElementsInMemory="1000" eternal="false"
    timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true" />
  <cache name="ehcacheName" maxElementsInMemory="10000"
    eternal="false" timeToIdleSeconds="300000" timeToLiveSeconds="600000"
    overflowToDisk="true" />
</ehcache>


     2，添加spring配置文件

     在applicContext.xml文件中添加



[html] ​​view plain​​ ​​copy​​

​​print​​​​?​​

  2.    <bean id="cacheManagerFactory"  
  3.     class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"  
  4.     p:configLocation="classpath:ehcache.xml"></bean>  
  5.   
  6. <!-- 声明cacheManager -->  
  7. <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager"   
  8.     p:cacheManager-ref="cacheManagerFactory" ></bean>  
<bean id="cacheManagerFactory"
    class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
    p:configLocation="classpath:ehcache.xml"></bean>
<!-- 声明cacheManager -->
<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager" 
  p:cacheManager-ref="cacheManagerFactory" ></bean></pre><br>
二：使用
     1，定义EHCache工具方法




[java] view plain copy
 print?

1. 

2. public class EHCache {  
3.     private static final CacheManager cacheManager = new CacheManager();  
4.     private Cache cache;  
5.     public EHCacheService(){  
6.         this.cache=cacheManager.getCache("ehcacheName")  
7.     }  
8.   
9.     public Cache getCache() {  
10.         return cache;  
11.     }  
12.   
13.     public void setCache(Cache cache) {  
14.         this.cache = cache;  
15.     }  
16.   
17.   
18.   
19.         /* 
20.      * 通过名称从缓存中获取数据 
21.      */  
22.     public Object getCacheElement(String cacheKey) throws Exception {  
23.             net.sf.ehcache.Element e = cache.get(cacheKey);  
24.         if (e == null) {  
25.             return null;  
26.         }  
27.         return e.getValue();  
28.     }  
29.     /* 
30.      * 将对象添加到缓存中 
31.      */  
32.     public void addToCache(String cacheKey, Object result) throws Exception {  
33.         Element element = new Element(cacheKey, result);  
34.         cache.put(element);  
35.     }  
36.   
37.   
38. }  
39. 



public class EHCache {
    private static final CacheManager cacheManager = new CacheManager();
    private Cache cache;
    public EHCacheService(){
        this.cache=cacheManager.getCache("ehcacheName")
    }
public Cache getCache() {
    return cache;
}

public void setCache(Cache cache) {
    this.cache = cache;
}



    /*
 * 通过名称从缓存中获取数据
 */
public Object getCacheElement(String cacheKey) throws Exception {
        net.sf.ehcache.Element e = cache.get(cacheKey);
    if (e == null) {
        return null;
    }
    return e.getValue();
}
/*
 * 将对象添加到缓存中
 */
public void addToCache(String cacheKey, Object result) throws Exception {
    Element element = new Element(cacheKey, result);
    cache.put(element);
}

}
          2，测试




[java] view plain copy
 print?

1. 

2. public class Test{  
3.     EHCache ehCache = new EHCache();  
4.     public void Test(){  
5.         //测试将json对象存入缓存中  
6.         JSONObject obj = new JSONObject();  
7.         obj.put("name","lsz");  
8.         ehCache.addToCache("cache_json",obj);  
9.   
10.         //从缓存中获取  
11.         JSONObject getobj = (JSONObject)ehCache.getCacheElement("cache_json");  
12.         System.out.println(getobj.toString());  
13.     }  
14. }  
15. 



public class Test{
    EHCache ehCache = new EHCache();
    public void Test(){
        //测试将json对象存入缓存中
        JSONObject obj = new JSONObject();
        obj.put("name","lsz");
        ehCache.addToCache("cache_json",obj);
    //从缓存中获取
    JSONObject getobj = (JSONObject)ehCache.getCacheElement("cache_json");
    System.out.println(getobj.toString());
}

}
三：问题解决
      1，框架环境是自己搭建的，添加ehcache后运行出错：
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/cache]

Offending resource: class path resource [applicationContext.xml]

      出现这种问题，原因是因为在applicationContext.xml文件中 多加了 
    <cache:annotation-driven cache-manager="cacheManager" /> 将其去掉即可

     2，框架需要添加jar包
     spring-context-support-3.2.0.RELEASE.jar
     spring-context-3.2.0.RELEASE.jar
