memcache與spring集成 實例

一、前期準備

1)  下載memcached服務端memcached-1.2.6-win32-bin.zip，地址：http://code.jellycan.com/memcached/

2)  下載java版客戶端 java_memcached-release_2.6.1.zip

3)  解壓縮memcached-1.2.6-win32-bin.zip到指定目錄，例如：D:\memcached-1.2.6-win32 ，在終端（即cmd命令行界面）

 

 

D:\memcached-1.2.6-win32\memcached.exe -d install
D:\memcached\memcached.exe -d start

這樣memcache就會作爲windows系統服務在每次開機時啓動memcache服務。

-p 監聽的端口 
-l 連接的IP地址, 默認是本機 
-d start 啓動memcached服務 
-d restart 重起memcached服務 
-d stop|shutdown 關閉正在運行的memcached服務 
-d install 安裝memcached服務 
-d uninstall 卸載memcached服務 
-u 以的身份運行 (僅在以root運行的時候有效) 
-m 最大內存使用，單位MB。默認64MB 
-M 內存耗盡時返回錯誤，而不是刪除項 
-c 最大同時連接數，默認是1024 
-f 塊大小增長因子，默認是1.25 
-n 最小分配空間，key+value+flags默認是48 
-h 顯示幫助 

二、實例代碼

spring-memcache.xml  配置pool和memcache客戶端

memcache.properties memcache的連接屬性 這是本機做服務器的，如果是其它機器，換ip 端口即可

memcache.server=127.0.0.1:11211
memcache.initConn=20
memcache.minConn=10
memcache.maxConn=50
memcache.maintSleep=3000
memcache.nagle=false
memcache.socketTO=3000 

TestMemcache.java測試類   用的是junit4

package com.pis.memcache;

import org.junit.Before;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.danga.MemCached.MemCachedClient;

public class TestMemcache {
    MemCachedClient memCachedClient;
    @Before
    public void beforeTest(){
        
        ApplicationContext atx = new ClassPathXmlApplicationContext("/spring/spring-memcache.xml");
        memCachedClient = (MemCachedClient)atx.getBean("memCachedClient");
    }
    
    
    @Test
    public void TestMem(){
        memCachedClient.set("name", "han");
        
        System.out.println(memCachedClient.get("name"));
    }
    
    
    
}
