来源：互联网发布：新郑办公软件培训班编辑：程序博客网时间：2024/06/05 09:00

1.下载依赖的JAR包

java_memcached-release_2.6.2.jar

commons-pool-1.5.6.jar

slf4j-api-1.6.1.jar

slf4j-simple-1.6.1.jar

2.JAVA程序

package com.memecached;import java.util.Date;import com.danga.MemCached.MemCachedClient;import com.danga.MemCached.SockIOPool;public class MemcachedExample {private  static MemCachedClient memCachedClient = new MemCachedClient();// 设置与缓存服务器的连接池static {// 服务器列表和其权重String[] servers = { "192.168.74.129:11211" };Integer[] weights = { 3 };// 获取socke连接池的实例对象SockIOPool pool = SockIOPool.getInstance();// 设置服务器信息pool.setServers(servers);pool.setWeights(weights);// 设置初始连接数、最小和最大连接数以及最大处理时间pool.setInitConn(5);pool.setMinConn(5);pool.setMaxConn(250);pool.setMaxIdle(1000 * 60 * 60 * 6);// 设置主线程的睡眠时间pool.setMaintSleep(30);// 设置TCP的参数，连接超时等pool.setNagle(false);pool.setSocketTO(3000);pool.setSocketConnectTO(0);// 初始化连接池pool.initialize();}public static void main(String[] args) {//key或value不能为空,否则不能存入memCachedClient.set("username", "张三");//添加键值对key=username,value=张三memCachedClient.set("username2", "张三", new Date(new Date().getTime() + 60*1000));//添加键值对key=username2,value=张三,并且指定有效期60秒System.out.println("username="+memCachedClient.get("username"));System.out.println("username2="+memCachedClient.get("username2"));memCachedClient.replace("username", "李四");//替换键username的值为李四memCachedClient.replace("username2", "李四", new Date(new Date().getTime() + 60*1000));//替换键username的值为李四,并且指定有效期60秒memCachedClient.add("username3", "张三");//添加键值对key=username,value=张三,只有当username3不存在时,才会添加System.out.println("username3="+memCachedClient.get("username3"));memCachedClient.delete("username3");//删除键值班对System.out.println("username3="+memCachedClient.get("username3"));System.out.println("statsItems:"+memCachedClient.statsItems());System.out.println("statsSlabs:"+memCachedClient.statsSlabs());}}

3.JAVA程序运行结果

username=张三username2=张三username3=张三username3=nullstatsItems:{192.168.74.129:11211={items:5:evicted_unfetched=3265507, items:1:evicted_unfetched=0, items:1:evicted_time=0, items:1:expired_unfetched=1, items:5:expired_unfetched=0, items:1:number=2, items:5:evicted_time=202, items:5:evicted=3265507, items:1:reclaimed=3, items:1:evicted_nonzero=0, items:5:tailrepairs=0, items:1:evicted=0, items:5:number=1734493, items:1:tailrepairs=0, items:1:age=0, items:5:age=7372, items:5:reclaimed=0, items:1:outofmemory=0, items:5:evicted_nonzero=0, items:5:outofmemory=0}}statsSlabs:{192.168.74.129:11211={5:chunk_size=240, 2:incr_hits=0, 2:cas_badval=0, 5:delete_hits=0, 1:cas_hits=0, 5:total_chunks=1734493, 2:used_chunks=0, 1:used_chunks=2, 5:chunks_per_page=4369, 5:decr_hits=0, 5:cas_badval=0, 5:free_chunks_end=0, 1:free_chunks=10920, 2:touch_hits=0, 5:get_hits=1734493, 2:total_pages=115, 2:delete_hits=0, 2:get_hits=1000000, 2:free_chunks=1004870, 2:total_chunks=1004870, 2:free_chunks_end=0, 1:chunks_per_page=10922, 5:incr_hits=0, 1:delete_hits=5, 1:incr_hits=0, 2:chunk_size=120, 5:mem_requested=364243530, 5:cas_hits=0, active_slabs=3, 1:touch_hits=0, 1:get_hits=25, 2:cmd_set=1000000, 1:total_chunks=10922, 2:decr_hits=0, 2:chunks_per_page=8738, 1:decr_hits=0, 5:total_pages=397, 2:cas_hits=0, total_malloced=537911232, 1:cmd_set=42, 5:cmd_set=6000000, 1:chunk_size=96, 1:cas_badval=0, 1:total_pages=1, 2:mem_requested=0, 1:free_chunks_end=0, 5:used_chunks=1734493, 1:mem_requested=161, 5:free_chunks=0, 5:touch_hits=0}}
