   在一个Java Project中添加Coherence.jar,在jar文件中config目录中存在默认的coherence的配置信息。

package com.etrip.app;

import com.tangosol.net.CacheFactory; 
import com.tangosol.net.NamedCache;
/**
 * 一个简单的Coherence的使用采用默认的coherence cache config配置文件
 * 
 * @Title: TODO
 * @Description: 实现TODO
 * @Copyright:Copyright (c) 2011
 * @Company:
 * @Date:2013-1-4
 * @author 
 * @version 1.0
 */
public class CoherenceCache {
    NamedCache cache;
    public CoherenceCache() {
    }
   
   /**
    * 从 CacheFactory 类中创建了一个缓存实例。使用 CacheFactory 类的 getCache() 
    * 方法创建一个 NamedCache。使用一个映射到分布式缓存模式的缓存名称 VirtualCache。
	* Named cache = CacheFactory.getCache ( "VirtualCache");
	* NamedCache 是一个保存整个集群中的节点所共享的资源的 java.util.Map。
	* 使用 put() 方法添加缓存项。cache.put (key, "Hello Cache");
	* 可以使用 get() 方法检索缓存项。
	* System.out.println((String)cache.get("hello"));
    */
   public void putCache(){
        cache = CacheFactory.getCache("VirtualCache"); 
       String key = "hello"; 
       cache.put (key, "Hello Cache"); 
   
   }
   
   
   public void retrieveCache(){
       System.out.println((String)cache.get("hello"));
   }
   
    public static void main (String [] args) {
	    CoherenceCache cache = new CoherenceCache(); 
	    cache.putCache();
	    cache.retrieveCache();
    }
    
}

 

执行结果如下：
