1. memcached client for java客户端API:memcached client for java
引入jar包:java-memcached-2.6.2.jar
package com.pcitc.memcached; import com.danga.MemCached.*; public class TestMemcached { public static void main(String[] args) { /* 初始化SockIOPool,管理memcached的连接池 */ String[] servers = { "192.168.1.111:11211" }; SockIOPool pool = SockIOPool.getInstance(); pool.setServers(servers); pool.setFailover(true); pool.setInitConn(10); pool.setMinConn(5); pool.setMaxConn(250); pool.setMaintSleep(30); pool.setNagle(false); pool.setSocketTO(3000); pool.setAliveCheck(true); pool.initialize(); /* 建立MemcachedClient实例 */ MemCachedClient memCachedClient = new MemCachedClient(); for (int i = 0; i < 10; i++) { /* 将对象加入到memcached缓存 */ boolean success = memCachedClient.set("" + i, "Hello!"); /* 从memcached缓存中按key值取对象 */ String result = (String) memCachedClient.get("" + i); System.out.println(String.format("set( %d ): %s", i, success)); System.out.println(String.format("get( %d ): %s", i, result)); } } }
2. spymemcached客户端API:spymemcached client
引入jar包:spymemcached-2.10.3.jar
package com.pcitc.memcached; import java.net.InetSocketAddress; import java.util.concurrent.Future; import net.spy.memcached.MemcachedClient; public class MClient { public static void main(String[] args) { setValue(); getValue(); } // 用spymemcached将对象存入缓存 public static void setValue() { try { /* 建立MemcachedClient 实例,并指定memcached服务的IP地址和端口号 */ MemcachedClient mc = new MemcachedClient(new InetSocketAddress( "192.168.1.111", 11211)); Future<Boolean> b = null; /* 将key值,过期时间(秒)和要缓存的对象set到memcached中 */ b = mc.set("neead", 900, "someObject"); if (b.get().booleanValue() == true) { mc.shutdown(); } } catch (Exception ex) { ex.printStackTrace(); } } // 用spymemcached从缓存中取得对象 public static void getValue() { try { /* 建立MemcachedClient 实例,并指定memcached服务的IP地址和端口号 */ MemcachedClient mc = new MemcachedClient(new InetSocketAddress( "192.168.1.111", 11211)); /* 按照key值从memcached中查找缓存,不存在则返回null */ Object b = mc.get("neead"); mc.shutdown(); } catch (Exception ex) { ex.printStackTrace(); } } }
3.两种API比较
memcached client for java:较早推出的memcached JAVA客户端API,应用广泛,运行比较稳定。
spymemcached:A simple, asynchronous, single-threaded memcached client written in java. 支持异步,单线程的memcached客户端,用到了java1.5版本的concurrent和nio,存取速度会高于前者,但是稳定性不好,测试中常报timeOut等相关异常。
由于memcached client for java发布了新版本,性能上有所提高,并且运行稳定,所以建议使用memcached client for java。
