Java 套接字客户端未检测到服务器消息
Java socket client doesn't detect server messages
我正在尝试 运行 远程主机上的 Java 服务器套接字,它将定期向所有连接的客户端广播消息(由外部进程确定)。
服务器套接字定义为:
ServerSocket serverSocket = (ServerSocket) ((ServerSocketFactory)ServerSocketFactory.getDefault()).createServerSocket(3050);
while (true) {
Socket socket = serverSocket.accept();
remoteService.addSocket(socket);
}
它将跟踪数组列表中的套接字连接。每当需要发送广播时,将调用以下方法:
public void broadcastMessage(String message){
for (Socket socket : remoteService.getSockets()) {
System.out.println("Sending message: " + message);
PrintWriter printWriter = new PrintWriter(socket.getOutputStream(), true);
printWriter.write(message);
}
}
在客户端,设置如下:
Socket socket = (Socket) ((SocketFactory) SocketFactory.getDefault()).createSocket(serverHost,portNum);
BufferedReader socketBufferedReader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
while (true) {
String message = socketBufferedReader.readLine();
if (message != null && message != "") {
System.out.println("Message received: " + message);
};
}
服务器正确打印 "Sending message" 字符串的次数与连接的客户端一样多,但是 none 的客户端进程打印任何内容。知道如何让客户端正确收听套接字输入流吗?
PrintWrite.println() 方法将打印给定的字符串并终止该行。在服务器端使用以下内容有效:
public void broadcastMessage(String message){
for (Socket socket : remoteService.getSockets()) {
System.out.println("Sending message: " + message);
PrintWriter printWriter = new PrintWriter(socket.getOutputStream(), true);
printWriter.println(message);
}
}
