为什么会出现“ java.net.SocketException：管道损坏”？（java管道破裂）

我写了一个简单的套接字程序，它工作正常，但是我的朋友使用端口扫描工具，当它扫描到我正在使用的端口时，它会收到“
java.net.SocketException：Broken pipe”错误，发生了什么？以及如何解决？

providerSocket = new ServerSocket(portNum);
connection = providerSocket.accept();
if (connection.getOutputStream() != null) {
    //this line crash!!!
    out = new ObjectOutputStream(connection.getOutputStream());
    out.flush();

}

控制台的详细信息错误：

java.net.SocketException: Broken pipe

    at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92)

ActiveMQ 错误 java.net.SocketException: Connection reset java.net.SocketException: Connection reset

最近在研究 ActiveMQ 控制台报错误 java.net.SocketException: Connection reset java.net.SocketException: Connection reset，客户端无法发送消息，客户端是使用Spring结合来做的，请问这个问题何解决？

Android java.net.SocketException：socket failed：EACCES(Permission denied)

嗨,我得到一个 Android应用程序,但是当我启动它,我的控制台中出现错误.我正在使用Datagram套接字创建一个连接,而我正在使用2类：MainActivity(它是应用程序的主要活动)和UdpClientServer来创建连接.

这里代码MainActivity：

public class MainActivity extends Activity {

private UdpClientServer cu;
private EditText textIpScheda;
private EditText textUdpPort;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    textIpScheda = (EditText) findViewById(R.id.textIpScheda);
    textUdpPort = (EditText) findViewById(R.id.textUdpPort);


    try {
        cu = new UdpClientServer(this);
    } catch (IOException e) {
        e.printstacktrace();
    }
}

public EditText getTextIpScheda(){
    return textIpScheda;
}

public void setTextIpScheda(EditText textIpScheda){
    this.textIpScheda = textIpScheda;
}

public EditText getTextUdpPort() {
    return textUdpPort;
}

public void setTextUdpPort(EditText textUdpPort) {
    this.textUdpPort = textUdpPort;
}

这里代码UdpClientServer：

public class UdpClientServer {

public static String sReceive;
private static DatagramSocket dSocket;
int receiveBufferSize = 1024;
int portUdp = 0;
final String PINGACMD = "AT*PINGA001";
InetAddress ipScheda;

byte[] receiveData = new byte[receiveBufferSize];
private MainActivity gui = null;

public UdpClientServer(MainActivity gui) throws SocketException,IOException {
    this.gui = gui;

    portUdp = Integer.parseInt(String.valueOf(gui.getTextUdpPort().getText()));
    dSocket = new DatagramSocket(portUdp);
}

public void run(){
    while (true) {
        // svuotamento buffer
        Arrays.fill(receiveData,(byte) 0);
        DatagramPacket receivePacket = new DatagramPacket(receiveData,receiveData.length);

        try {
            dSocket.receive(receivePacket);
        } catch (IOException e) {
            e.printstacktrace();
        }
        ipScheda = receivePacket.getAddress();
        int port = receivePacket.getPort();
        gui.getTextUdpPort().setText("" + port);
        gui.getTextIpScheda().setText(ipScheda.getHostAddress());

        sReceive = new String(receivePacket.getData());
        this.sendCommand(PINGACMD);
    }

}

public void sendCommand(String outSentence){

    byte[] sendData = outSentence.getBytes();

    DatagramPacket sendPacket = new DatagramPacket(sendData,sendData.length,ipScheda,portUdp);

    try {
        dSocket.send(sendPacket);
        Thread.sleep(100);
    } catch (IOException e) {
        e.printstacktrace();
    } catch (InterruptedException e) {
        e.printstacktrace();
    }
    finally {
    }
}

}

在我的AndroidManifest.xml中刚刚添加了字符串

<uses-permission android:name="android.permission.INTERNET"/>

但它不行

你可以帮我吗？
谢谢

解决方法

尝试添加以下内容：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

Android java.net.SocketException：权限被拒绝

如何解决Android java.net.SocketException：权限被拒绝？

我是一名Android初学者。我想创建一个ServerSocket，但是它总是在“ serverSocket = new ServerSocket（12345）;”行上调用“ java.net.socketException：权限被拒绝”。我想知道为什么，谢谢。

ServerThread.java

public class ServerThread extends Thread {
    ServerSocket serverSocket ;
    @Override
    public void run() {
        try {
            serverSocket = new ServerSocket(12345);
            while(true) {
                System.out.println("IN");
                Socket socket = serverSocket.accept(); // null
            }
        } catch (IOException e) {
            e.printstacktrace();
        }
    }
}

MainActivity.java

public class MainActivity extends AppCompatActivity {

   @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        new ServerThread().start();
    }
}

Android：套接字-java.net.SocketException：sendto失败：EPIPE（管道断开）

我正在尝试使用套接字与服务器建立连接。连接管道损坏，如下所示。

这是代码，在此行上outStreamRec.write(bData);引发异常。

    try {
        port = 86;
        byterecv = new byte[1040];
        clientRec = new Socket();
        clientRec.connect(new InetSocketAddress("192.168.1.36",port));
        System.out.println("Just connected to " + clientRec.getRemoteSocketAddress());
    } catch (IOException e2) {
        // TODO Auto-generated catch block
        e2.printStackTrace();
    }
    while (true) {
        try {
            System.out.println("Connecting to " + ServerUrl.url + " on port " + port);              
            OutputStream outToServerRec = clientRec.getOutputStream();
            DataOutputStream outStreamRec = new DataOutputStream(outToServerRec);

            outStreamRec.write(bData);

            InputStream inFromServerPlay = clientRec.getInputStream();
            DataInputStream inStreamPlay = new DataInputStream(inFromServerPlay);
            while ((lstream = inStreamPlay.read(byterecv)) != -1) {
                System.out.println("startrec bytearray -- " + byterecv.length);
                bos1.write(byterecv,lstream);
            }                
            if (stopcall == true) {
                clientRec.close();
                break;
            }

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

注意：如果我关闭套接字连接，立即可以正常工作。但是我想保持连接仍然活跃，所以我手动关闭套接字连接。停止按钮的onclick我正在关闭连接。

我在网上搜索，但没有找到解决此问题的方法。
