配置Memcached Java
朋友公司开发的项目要用到缓存,于是叫我推荐一个,我说我们公司在用Memcached,然后就问了我一堆关于Memcached的问题,直接把我问的无言了,因为虽然项目用到了,但是我自己却没搞过这个,只是知道有这么个东西存在,唉…
准备工作:
1.从http://splinedancer.com/memcached-win32/下载Memcached for Windows。解压至任意目录(如C:\memcached),然后执行如下DOS命令进行安装:
C:\memcached>memcached.exe -d install C:\memcached>memcached.exe -d start
2.从https://github.com/gwhalin/Memcached-Java-Client下载Memcached相关的jar包。
测试程序:
package webshell.cc; import com.danga.MemCached.MemCachedClient; import com.danga.MemCached.SockIOPool; public class MemCachedTest { private static MemCachedClient mcc = new MemCachedClient(); static { String[] servers = {"192.168.0.107:11211"}; //创建一个连接池 SockIOPool pool = SockIOPool.getInstance(); //设置缓存服务器 pool.setServers(servers); //设置初始化连接数,最小连接数,最大连接数以及最大处理时间 pool.setInitConn(50); pool.setMinConn(50); pool.setMaxConn(500); pool.setMaxIdle(1000 * 60 * 60); //设置主线程睡眠时间,每30秒苏醒一次,维持连接池大小 pool.setMaintSleep(30); //关闭套接字缓存 pool.setNagle(false); //连接建立后的超时时间 pool.setSocketTO(3000); //连接建立时的超时时间 pool.setSocketConnectTO(0); //初始化连接池 pool.initialize(); } protected MemCachedTest(){ } public static MemCachedClient getInstance(){ return mcc; } public static void main(String[] args) { MemCachedClient cache = MemCachedTest.getInstance(); User u1 = new User(); u1.setName("Neeke"); u1.setBlog("http://www.ineeke.com"); cache.add("neeke", u1); User u2 = (User) cache.get("neeke"); System.out.println("name=" + u2.getName()); u2.setName("other"); cache.replace("neeke", u2); u2 = (User) cache.get("neeke"); System.out.println("name=" + u2.getName()); } }
