第一步：安装Memcached 服务端

1、CentOs(6.4)服务器安装Memcached 服务端（可以查看：[cenos 6.4 安装memcached 服务端][cenos 6.4 _memcached]）

2、下载java版客户端 java\_memcached-release\_2.6.1.zip

3、CentOs(6.4)服务器启动Memcached 服务端

memcached 关联jar

java_memcached-release_2.6.6.jar

第二步：配置memcached.properties文件

memcache.server=120.25.56.93:11211
    memcache.initConn=20
    memcache.minConn=10
    memcache.maxConn=50
    memcache.maintSleep=3000
    memcache.nagle=false
    memcache.socketTO=3000

第三步：spring配置文件集成memcached

第四步:memcached 功能测试

package com.wlsq.oauth.controller;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import com.danga.MemCached.MemCachedClient;
    
    @Controller 
    public class MemcachedController {
    		@Autowired
    		private MemCachedClient memCachedClient;
    	
    		@RequestMapping("/memcached")
    		public void setMemcachedServer(){
    			Boolean target=memCachedClient.set("1", "123456");
    			System.out.println("memcached 加载是否成功："+target);
    			String result =(String)memCachedClient.get("1");
    			System.out.println("memcached 获取的结果："+result);		
    			
    		}
    
    }

执行的结果如下截图所示：
