void	destroyObject(ServerNode key, T client) 销毁对象
T	makeObject(ServerNode key) 生成对象
boolean	validateObject(ServerNode key, T client) 验证链接有效性 注意：在服务端口异常关闭的情况下，tp.isOpen() 仍然返回true,所以，正常情况下应该进行socket验证，考虑到服务异常时使用了deadmark算法切换服务，故这里就不需要下面的验证代码了。

验证链接有效性
注意：在服务端口异常关闭的情况下，tp.isOpen() 仍然返回true,所以，正常情况下应该进行socket验证，考虑到服务异常时使用了deadmark算法切换服务，故这里就不需要下面的验证代码了。

 
    Socket socket = null;
         try {
             InetSocketAddress socketAddress = new InetSocketAddress(key.getIp(), key.getPort());
             socket = new Socket();
             socket.connect(socketAddress, 1000);
         } catch (IOException e) {
             LOGGER.warn(e.getMessage(), e);
             return false;
         } finally {
             if (socket != null) {
                 try {
                     socket.close();
                 } catch (IOException e) {
                     LOGGER.warn(e.getMessage(), e);
                 }
             }
         }
