ssm 架構內建memcached 緩存伺服器

第一步：安裝Memcached 服務端

1、CentOs(6.4)伺服器安裝Memcached 服務端（可以檢視：cenos 6.4 安裝memcached 服務端）

2、下載下傳java版用戶端 java_memcached-release_2.6.1.zip

3、CentOs(6.4)伺服器啟動Memcached 服務端

memcached 關聯jar

java_memcached-release_2.6.6.jar

第二步：配置memcached.properties檔案

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配置檔案內建memcached

第四步:memcached 功能測試

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 加載是否成功："+target);
			String result =(String)memCachedClient.get("1");
			System.out.println("memcached 擷取的結果："+result);		
			
		}

}

執行的結果如下截圖所示：
