套接字关闭异常

我写了一个简单的服务器和客户端的例子如下。套接字关闭异常

客户：

打开一个连接
获取的OutputStream，写入流并关闭输出流

获取InputStream和从流中读取。

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); 
    } 

} 

}

获得以下插座闭合异常的客户：在这一点上

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); 
} 
    } 

    }

客户端获取异常。请让我知道是什么原因。

java.net.SocketException异常关闭套接字此异常意味着你关闭套接字，然后继续尝试使用它。

os.close();

然后你在这里关闭它。关闭Socket的输入或输出流会关闭另一个流和Socket。

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

@Abhilash无关。 'isConnected（）'告诉你是否曾经连接过'Socket.' *** Not ***它是否已经连接。（'isConnected（）'和'isClosed（）'方法关于* socket的状态，*不是连接的状态。） – EJP

java.net.SocketException仅当您在从服务器读取数据之前关闭OutputStream（或）Socket时才会出现。

从您的代码，删除：

OutputStream.close();

，然后尝试..
