为什么客户端建立连接后此端口/套接字会关闭?

package app;

import java.io.*;
import java.net.*;

public class socketServer {

public static void main(String[] args) {
    int port = 3333;
    boolean socketBindedToPort = false;

    try {
        ServerSocket ServerSocketPort = new ServerSocket(port);
        System.out.println("SocketServer Set Up on Port: " + port);
        socketBindedToPort = true;

        if(socketBindedToPort == true) {
            Socket clientSocket = null;

            try {
                clientSocket = ServerSocketPort.accept();//This method blocks until a socket connection has been made to this port.
                System.out.println("Waiting for client connection on port:" + port);
                /** THE CLIENT HAS MADE A CONNECTION **/
                System.out.println("CLIENT IS CONENCTED");
            } 
            catch (IOException e) {
                System.out.println("Accept failed: " + port);
                System.exit(-1);
            }
        }
        else {
            System.out.println("Socket did not bind to the port:" + port);
        }
    }
    catch(IOException e) {
        System.out.println("Could not listen on port: " + port);
        System.exit(-1);
    }



}

未经测试,但我很确定这是因为您的计划中没有其他内容。一旦ServerSocketPort.accept();完成后,程序将结束主程并关闭。

您需要向其添加一个对客户端做出反应的流。

试试这个:

Socket accepted = serverSocketPort.accept();
InputStream inStr = accepted.getInputStream();

该程序运行得非常好。一旦客户端连接或 ServerSocket 超时,停止。你的目标是什么?

@Matthew。

恕我直言,乔尔最接近你的问题。

“连接已关闭,因为程序在接受连接后存在”

通常,accept在循环中运行,以便服务器继续监听端口上的连接请求
