Java连接并使用Memcached

jar包准备：spymemcached-2.10.3.jar

本代码实现了如何新增，删除，替换，加减，追加字符串，保存对象
基本操作如下：

public static void main(String[] args) throws Exception {
        InetSocketAddress ia=new InetSocketAddress("127.0.0.1", 11211) ;
        MemcachedClient memcachedClient=new MemcachedClient(ia);
        System.out.println("Connection to server sucessful.");
        System.out.println("-------------------------------set保存-------------------------------------------");
        Future operationFuture=memcachedClient.set("name", 900, "张三");
        System.out.println("set保存name："+operationFuture.get()); //查询保存状态
        System.out.println("set保存后获取name的值："+memcachedClient.get("name"));
        System.out.println("-------------------------------set保存对象-------------------------------------------");
        User user=new User("王五","wangwu");
        operationFuture=memcachedClient.set("user", 900, user);
        System.out.println("set保存user："+operationFuture.get()); //查询保存状态
        user=(User) memcachedClient.get("user");
        System.out.println("set保存后获取user name的值："+user.getName() );
        System.out.println("set保存后获取user pwd的值："+user.getPwd());
        System.out.println("-------------------------------add保存-------------------------------------------");
        operationFuture=memcachedClient.add("addname", 900, "add张三");
        System.out.println("add保存addname："+operationFuture.get()); //查询保存状态
        System.out.println("add保存后获取name的值："+memcachedClient.get("addname"));
        System.out.println("-------------------------------replace替换-------------------------------------------");
        operationFuture=memcachedClient.replace("name", 900, "李四");
        System.out.println("replace替换状态："+operationFuture.get()); //查询保存状态
        System.out.println("替换后name的值："+memcachedClient.get("name"));

        System.out.println("-------------------------------append-------------------------------------------");
        operationFuture=memcachedClient.append("name", "append");
        System.out.println("append状态："+operationFuture.get()); //查询保存状态
        System.out.println("append后name的值："+memcachedClient.get("name"));

        System.out.println("-------------------------------prepend-------------------------------------------");
        operationFuture=memcachedClient.prepend("name", "prepend");
        System.out.println("prepend状态："+operationFuture.get()); //查询保存状态
        System.out.println("prepend后name的值："+memcachedClient.get("name"));

        System.out.println("-------------------------------delete删除-------------------------------------------");
        operationFuture=memcachedClient.delete("name");
        System.out.println("delete删除name："+operationFuture.get()); //查询保存状态
        System.out.println("删除后name的值："+memcachedClient.get("name"));
        operationFuture=memcachedClient.delete("addname");
        System.out.println("delete删除addname："+operationFuture.get()); //查询保存状态
        System.out.println("删除后addname的值："+memcachedClient.get("addname"));

        System.out.println("-------------------------------加减-------------------------------------------");
        operationFuture=memcachedClient.set("num", 900, 10);
        System.out.println("set保存num："+operationFuture.get()); //查询保存状态
        System.out.println("num计算前的值："+memcachedClient.get("num"));
        System.out.println("num+5："+ memcachedClient.incr("num", 5));
        System.out.println("num-1："+memcachedClient.decr("num", 1));
        operationFuture=memcachedClient.delete("num");
        System.out.println("delete删除num："+operationFuture.get()); //查询保存状态
        System.out.println("删除后num的值："+memcachedClient.get("num"));
        // 关闭连接
        memcachedClient.shutdown();
    }

输出结果值：
