解决方案
解决方案二：
卡死?哈哈.其实一点不卡的.正如你端口查询结果一样,一直监听那些来连接这个serverSocket.你这里仅仅生成了一个ServerSocket,这相当于服务器,他们的任务是等待Socket.所以你要另外生成一个socket=newSocket("127.0.0.1",51706);
解决方案三：
还需要一个客户端socket比如客户端socket应该这样写ClientSocket{Socketsocket=newSocket("127.0.0.1",51706);}服务端socket应该这样写ServerSocket{ServerSocketserverSocket=newServerSocket(51706);Socketsocket=serverSocket.accept();}
解决方案四：
Socketsocket=serverSocket.accept();serveraccept后，一定要新起线程去处理数据交流..否则程序不继续，后面的client连接就不能处理了。
