[英]Java TCP socket listener
I have very simple TCP socket listener. 我有一个非常简单的TCP套接字侦听器。 I want to stop receiving data when the character is
null
or #
. 我想在字符为
null
或#
时停止接收数据。
while ((line = in.readLine()) != null && !line.equals("#")){
tcpData = tcpData + line;
}
server.close();
is not closing the socket as code flows. 代码流时未关闭套接字。 The socket closed only when I am closing from Hyperterminal.
仅当我从超级终端关闭时,套接字才关闭。 What I missed ?
我错过了什么?
Because readLine()
only returns null at end of stream, which only occurs in TCP sockets when the peer has closed the connection. 因为
readLine()
仅在流的末尾返回null,这仅在对等方关闭连接时在TCP套接字中发生。
... and clearly you are never sending a line consisting of #
plus a line terminator. ……显然,您永远不会发送由
#
加行终止符组成的行。
