Java_memcached 使用说明

1.加载commons-pool-1.5.6.jar、java_memcached-release_2.6.6.jar、slf4j-api-1.6.1.jar、slf4j-simple-1.6.1.jar



2.创建memcached工具类：

public class MemcachedUtil {

	/**
	 * memcached客户端单例
	 */
	private static MemCachedClient cachedClient = new MemCachedClient();
	
	/**
	 * 初始化连接池
	 */
	static {
		//获取连接池的实例
		SockIOPool pool = SockIOPool.getInstance();
		
		//服务器列表及其权重
		String[] servers = {"127.0.0.1:11211"};
		Integer[] weights = {3};
		
		//设置服务器信息
		pool.setServers(servers);
		pool.setWeights(weights);
		
		//设置初始连接数、最小连接数、最大连接数、最大处理时间
		pool.setInitConn(10);
		pool.setMinConn(10);
		pool.setMaxConn(1000);
		pool.setMaxIdle(1000*60*60);
		
		//设置连接池守护线程的睡眠时间
		pool.setMaintSleep(60);
		
		//设置TCP参数，连接超时
		pool.setNagle(false);
		pool.setSocketTO(60);
		pool.setSocketConnectTO(0);
		
		//初始化并启动连接池
		pool.initialize();
		
		//压缩设置，超过指定大小的都压缩
//		cachedClient.setCompressEnable(true);
//		cachedClient.setCompressThreshold(1024*1024);
	}
	
	private MemcachedUtil(){
	}
	
	public static boolean add(String key, Object value) {
		return cachedClient.add(key, value);
	}
	
	public static boolean add(String key, Object value, Integer expire) {
		return cachedClient.add(key, value, expire);
	}
	
	public static boolean put(String key, Object value) {
		return cachedClient.set(key, value);
	}
	
	public static boolean put(String key, Object value, Integer expire) {
		return cachedClient.set(key, value, expire);
	}
	
	public static boolean replace(String key, Object value) {
		return cachedClient.replace(key, value);
	}
	
	public static boolean replace(String key, Object value, Integer expire) {
		return cachedClient.replace(key, value, expire);
	}
	
	public static Object get(String key) {
		return cachedClient.get(key);
	}
	
}
