客户端/服务器应用程序连接重置Java

当我在运行服务器后运行客户端时，服务器会因错误连接重置而崩溃。。。这是我的密码：

启动客户端套接字并连接到服务器。等待输入。 客户：

启动服务器套接字并向客户端发送“2”并启动对话

服务器：

    public ServerTest() {
    try {
        serverSocket = new ServerSocket(25565);
        clientSocket = serverSocket.accept();

    } 
    catch (IOException e) {
        System.out.println("Could not listen on port: 4444");
        System.exit(-1);
    }
    start();
}

public void start() {

    try {
        PrintWriter out;
        out = new PrintWriter(clientSocket.getOutputStream(), true);
        BufferedReader in;
        in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
        String inputLine, outputLine;
        // initiate conversation with client
        out.println("2");
            while ((inputLine = in.readLine()) != null) {   
                System.out.println(inputLine);
                out.println("2");
            }
        System.out.println("Stopping");
        out.close();
        in.close();
        clientSocket.close();
        serverSocket.close();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

public static void main(String[] args) {
    new ServerTest();
}

当我运行服务器时，一切正常，但当我运行客户端之后，服务器崩溃，出现连接重置错误。

ClientTest（）不调用start（）方法。您的客户端在建立连接后立即退出。

Alex的回答是正确的

这个程序也进入无限循环。您需要在客户端和服务器的while循环中添加一个退出条件。

您可以添加堆栈跟踪吗？但它会立即崩溃，说连接重置我认为这与无限循环无关

    public ServerTest() {
    try {
        serverSocket = new ServerSocket(25565);
        clientSocket = serverSocket.accept();

    } 
    catch (IOException e) {
        System.out.println("Could not listen on port: 4444");
        System.exit(-1);
    }
    start();
}

public void start() {

    try {
        PrintWriter out;
        out = new PrintWriter(clientSocket.getOutputStream(), true);
        BufferedReader in;
        in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
        String inputLine, outputLine;
        // initiate conversation with client
        out.println("2");
            while ((inputLine = in.readLine()) != null) {   
                System.out.println(inputLine);
                out.println("2");
            }
        System.out.println("Stopping");
        out.close();
        in.close();
        clientSocket.close();
        serverSocket.close();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

public static void main(String[] args) {
    new ServerTest();
