java - 对象输入流 : StreamCorruptedException

Question

大家好，我必须编写一个通过套接字连接进行通信的服务器。 客户端将对象发送到服务器，服务器将其打印到控制台。

public class ConnectionListener {

ServerSocket providerSocket;
Socket connection = null;
ObjectOutputStream out;
ObjectInputStream in;
Object message;

void runListener()
{
    try{
        providerSocket = new ServerSocket(2004, 10);
        System.out.println("Waiting for connection");
        connection = providerSocket.accept();
        System.out.println("Connection received from " + connection.getInetAddress().getHostName());
        in = new ObjectInputStream(connection.getInputStream());
        out = new ObjectOutputStream(connection.getOutputStream());
        do{
            message = in.readObject();
            System.out.println("client>" + message);
        }while(!message.equals("bye"));
    }
    catch(IOException ioException){
        ioException.printStackTrace();
    } catch (ClassNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    finally{
        try{
            in.close();
            out.close();
            providerSocket.close();
        }
        catch(IOException ioException){
            ioException.printStackTrace();
        }
    }
}

}

但我总是在这一行变成 StreamCorruptedException:

in = new ObjectInputStream(connection.getInputStream());

有人可以帮我吗？

谢谢

Answer 1

I´m connecting to the server via telnet and sending normal text input.

所以另一端根本没有使用ObjectOutputStream，所以使用ObjectInputStream只是废话。

如果您只想读取文本，请使用BufferedReader.readLine()。
