套接字關閉異常

我寫了一個簡單的服務器和客戶端的例子如下。套接字關閉異常

客戶：

打開一個連接
獲取的OutputStream，寫入流並關閉輸出流

獲取InputStream和從流中讀取。

public class DateClient { 

public static void main(String[] args) throws UnknownHostException, 
     IOException, InterruptedException { 
    Socket sock = new Socket("127.0.0.1", 6013); 
    OutputStream outputStream = sock.getOutputStream(); 
    InputStream inputStream = sock.getInputStream(); 

    System.out.println("" + outputStream + "-" + inputStream); 

    PrintWriter printWriter = new PrintWriter(outputStream, true); 
    printWriter.println("Hi Server"); 

    outputStream.close(); 

    System.out.println(sock.isConnected()); 

    BufferedReader bufferedReader = new BufferedReader(
      new InputStreamReader(inputStream)); 
    String line; 
    while ((line = bufferedReader.readLine()) != null) { // Exception 
     System.out.println(line); 
    } 

} 

}

獲得以下插座閉合異常的客戶：在這一點上

public class DateServer { 
public static void main(String[] args) throws InterruptedException { 
ServerSocket serverSocket = null; 
Socket client = null; 
try { 
    serverSocket = new ServerSocket(6013); 
    while (true) { 
     client = serverSocket.accept(); 
     OutputStream outputStream = client.getOutputStream(); 
     InputStream inputStream = client.getInputStream(); 

     System.out.println("" + outputStream + "-" + inputStream); 

     BufferedReader bufferedReader = new BufferedReader(
       new InputStreamReader(inputStream)); 

     String line = null; 
     while ((line = bufferedReader.readLine()) != null) { 
      System.out 
        .println("Message recieved from client ::" + line); 
     } 

     PrintWriter printWriter = new PrintWriter(outputStream, true); 

     printWriter.println(new java.util.Date().toString()); 

     client.close(); 
    } 
} catch (IOException exception) { 
    exception.printStackTrace(); 
    System.err.println(exception); 
} 
    } 

    }

客戶端獲取異常。請讓我知道是什麼原因。

java.net.SocketException異常關閉套接字此異常意味着你關閉套接字，然後繼續嘗試使用它。

os.close();

然後你在這裏關閉它。關閉Socket的輸入或輸出流會關閉另一個流和Socket。

但是'的System.out.println（sock.isConnected（））;'是印刷真實 – Abhilash

@Abhilash無關。 'isConnected（）'告訴你是否曾經連接過'Socket.' *** Not ***它是否已經連接。（'isConnected（）'和'isClosed（）'方法關於* socket的狀態，*不是連接的狀態。） – EJP

java.net.SocketException僅當您在從服務器讀取數據之前關閉OutputStream（或）Socket時纔會出現。

從您的代碼，刪除：

OutputStream.close();

，然後嘗試..
