【中文标题】***Error 然后 SocketException:软件导致连接中止:套接字写入错误 [重复]【英文标题】:***Error then SocketException: Software caused connection abort: socket write error [duplicate] 【发布时间】:2014-10-12 04:32:22 【问题描述】:

我正在尝试制作一个程序,它将向服务器发送文件和消息,还检测服务器何时断开连接(可能是因为关闭应用程序等)所以我所做的就是让客户端读取,当我第一次单击按钮btnItem 时,它可以正常工作,但是当我再次单击它时,它在healthChecker 上给了我这个错误***Error

问题:如何修复 ***Error

这是我的代码:

服务器

public class Server extends JFrame

    JPanel server=new JPanel();
    JPanel main=new JPanel();
    JPanel top=new JPanel();
    JPanel bot=new JPanel();
    JTextArea console=new JTextArea();

    public Server()
    
        super("Server");
        server.setLayout(new BorderLayout());
        main.setLayout(new BorderLayout());
        top.setLayout(new BorderLayout());
        bot.setLayout(new BorderLayout());
        console.setEditable(false);
        console.setFont(new Font("Courier New",Font.PLAIN,14));
        console.setBackground(Color.BLACK);
        console.setForeground(Color.WHITE);
        bot.add(console);
        main.add(top,BorderLayout.NORTH);
        main.add(bot,BorderLayout.CENTER);
        add(main);
    

    public static void main(String[] args) 
    
        Server f=new Server();
        f.setVisible(true);
        f.setExtendedState(JFrame.MAXIMIZED_BOTH);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Thread s1=new Thread(new Socket1(f.console));
        s1.start();
        Thread s2=new Thread(new Socket2());
        s2.start();

    

Socket1

public class Socket1 implements Runnable

    JTextArea console;

    public Socket1(JTextArea console)
    
        this.console=console;
    

    public void run()
    
        try
        
            int port=4000;
            ServerSocket checker=new ServerSocket(port);
            console.append("Server is up and listening to port:"+port+"\r\n");
            while(true)
            
                Socket socket=checker.accept();
                InputStreamReader streamReader=new InputStreamReader(socket.getInputStream());
                BufferedReader reader=new BufferedReader(streamReader);
                String[] received=reader.readLine().split("~");
                console.append(received[1]+": requesting for "+received[0]+"\r\n");
                Thread createfile=new Thread(new Creator(received[0],received[1],console));
                createfile.start();
            
        catch(Exception ex)
        
            ex.printStackTrace();
        
    

客户

public class Branch extends JFrame

    private InetAddress address;
    private String IP="localhost";
    private int port=4000;

            String send="";
            try
            
                //myIP=InetAddress.getLocalHost().getHostAddress();
                send="item~"+myIP;
                request(send);
            catch(Exception ex)
            
                JOptionPane.showMessageDialog(null,ex.getMessage());
            
        
    ;

    private void request(String send)
    
        try
        
            OutputStream os = socket.getOutputStream();

            ex.printStackTrace();
        
    

    public Branch()
    
        super("Branch");
        scrollv.setAutoscrolls(true);
        caret.setUpdatePolicy(DefaultCaret.ALWAYS_UPDATE);
        main.setLayout(new BorderLayout());
        console.setFont(new Font("Courier New",Font.PLAIN,14));
        top.setLayout(new FlowLayout());
        top.add(btnItem);
        top.add(btnGlstock);
        btnItem.addActionListener(item);
        btnGlstock.addActionListener(glstock);
        bot.setLayout(new BorderLayout());
        console.setEditable(false);
        console.setForeground(Color.white);
        console.setBackground(Color.black);
        bot.add(scrollv,BorderLayout.CENTER);
        main.add(top,BorderLayout.NORTH);
        main.add(bot,BorderLayout.CENTER);
        add(main);
    

    private void healthChecker()
    
        try
        
            socket.setSoTimeout(5000);
            InputStreamReader isr=new InputStreamReader(socket.getInputStream());
            isr.read();

        catch(SocketException ex)
        
            ex.printStackTrace();
            try
            
                connect2Server();
            catch(Exception exc)
            

            
        
        catch(SocketTimeoutException ex)
        

        
        catch(IOException ex)
        

        
        healthChecker();
    

    private void connect2Server() throws IOException
    
        try
        
            socket = new Socket(IP,port);
            console.append("You are now Connected to the Server\r\n");
            healthChecker();

            connect2Server();
        
    

    public static void main(String args[])
    
        Branch frame=new Branch();
        frame.setVisible(true);
        frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        try
        
            frame.connect2Server();
        catch(IOException ex)
        

        
    

更新

我试图编辑healthChecker() 现在它给了我SocketException: Software caused connection abort: socket write error

private void healthChecker()

    try
    
           socket.setSoTimeout(5000);
           InputStreamReader isr=new InputStreamReader(socket.getInputStream());
           isr.read();

    
    catch(SocketException ex)
    
         ex.printStackTrace();
         try
         
             connect2Server();
         catch(Exception exc)
         
             ex.printStackTrace();
         
    
    catch(SocketTimeoutException ex)
    
         ex.printStackTrace();  
    
    catch(IOException ex)
    
         ex.printStackTrace();       
    
 

【问题讨论】:

你有无限递归。 @EJP 抱歉,我的理解很差...您能向我解释一下我的问题的解决方案是什么或如何解决吗? @askManiac 这一切都在这个重复的问题的答案中得到了解释。 【参考方案1】:

在您的方法healthchecker() 中,您再次调用healthChecker()。这导致非终止递归。每个递归级别都会在堆栈上放一些东西,最后堆栈是满的。以下方法调用导致溢出。

【讨论】:

+1 解释。 还是connect2Server()的非终止递归 查看更新 :D 我将如何持续检查服务器是否在线?【参考方案2】:

如错误消息所示,问题出在客户端代码中的 healthChecker 中。

private void healthChecker()
    try
    
        socket.setSoTimeout(5000);
        InputStreamReader isr=new InputStreamReader(socket.getInputStream());
        isr.read();

    catch(SocketException ex)
    
        ex.printStackTrace();
        try
        
            connect2Server();
        catch(Exception exc)
        

        
    
    catch(SocketTimeoutException ex)
    

    
    catch(IOException ex)
    

    
  healthChecker();

倒数第二行的调用是这里的问题。 无论如何,healthChecker 总是递归调用自己,没有退出条件会阻止它这样做。 因此,在运行时,它会在调用堆栈上堆积越来越多的指针,最终导致 ***。

进行递归调用时,请确保始终有退出条件。 否则,递归调用将永远持续下去,这将产生 *** 错误。
