class TextServer
{
public static void main(String[] args) throws Exception
{
ServerSocket ss = new ServerSocket(10006);
Socket s =ss.accept();
String ip = s.getInetAddress().getHostAddress();
System.out.println(ip+"客户端连接");
BufferedReader bufIn = new BufferedReader(new InputStreamReader(s.getInputStream()));
PrintWriter out = new PrintWriter(new FileWriter("C:\\whataup.txt"),true);
//接收时间戳标记
DataInputStream dis = new DataInputStream(s.getInputStream());
long l = dis.readLong();
System.out.println("服务端第一次"+l);
String line = null;
while((line = bufIn.readLine()) != null )
{
/*时间戳标记判断结束*/
out.println(line);
}
PrintWriter feedback = new PrintWriter(s.getOutputStream(),true);
feedback.println("上传成功");
dis.close();
out.close();
s.close();
}
}
对于用时间戳来结束服务器端的语句，那个判断语句我一直写不对，有人能帮忙不？
