Java:网络中的EOFEException

我是网络新手，当我试图运行MyClient.java时，我遇到了一个EOFEException

MyServer.java

public class MyServer {
    public static void main(String[] args) {
        ServerSocket serverSocket = null;
        try {
            serverSocket = new ServerSocket(4321);
        } catch (IOException e) {
            e.printStackTrace();
        }
        while(true) {
            try {
                Socket socket = serverSocket.accept();
                OutputStream os =socket.getOutputStream();
                OutputStreamWriter osw = new OutputStreamWriter(os);
                BufferedWriter bw = new BufferedWriter(osw);
                bw.write("Hello networking");

                bw.close();
                socket.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

public class MyClient {
    public static void main(String[] args) {
        Socket socket = null;
        try {
            socket = new Socket("127.0.0.1", 4321);
            InputStream is = socket.getInputStream();
            DataInputStream dis = new DataInputStream(is);
            System.out.println(dis.readUTF());

            dis.close();
            socket.close();
        } catch (UnknownHostException e) {
            e.printStackTrace();
        } catch (ConnectException e) {
            System.err.println("Could not connect");
        } catch (UTFDataFormatException e) {
            System.err.println("if the bytes do not represent a valid modified UTF-8 encoding of a string");
        } catch (EOFException e) {
            System.err.println("if this input stream reaches the end before reading all the bytes");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

MyClient.java

public class MyServer {
    public static void main(String[] args) {
        ServerSocket serverSocket = null;
        try {
            serverSocket = new ServerSocket(4321);
        } catch (IOException e) {
            e.printStackTrace();
        }
        while(true) {
            try {
                Socket socket = serverSocket.accept();
                OutputStream os =socket.getOutputStream();
                OutputStreamWriter osw = new OutputStreamWriter(os);
                BufferedWriter bw = new BufferedWriter(osw);
                bw.write("Hello networking");

                bw.close();
                socket.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

public class MyClient {
    public static void main(String[] args) {
        Socket socket = null;
        try {
            socket = new Socket("127.0.0.1", 4321);
            InputStream is = socket.getInputStream();
            DataInputStream dis = new DataInputStream(is);
            System.out.println(dis.readUTF());

            dis.close();
            socket.close();
        } catch (UnknownHostException e) {
            e.printStackTrace();
        } catch (ConnectException e) {
            System.err.println("Could not connect");
        } catch (UTFDataFormatException e) {
            System.err.println("if the bytes do not represent a valid modified UTF-8 encoding of a string");
        } catch (EOFException e) {
            System.err.println("if this input stream reaches the end before reading all the bytes");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

如果此输入流在读取错误的所有字节之前到达末尾，并且错误似乎是由dis.readUTF（）调用引起的，则我得到

有人能帮我理解我错过了什么吗？我正在尝试读取服务器连接到客户端时写入的内容，即Hello networking

谢谢。

问题在于您的服务器代码

如果要使用DataInputStream读取套接字，则应使用DataOutputStream.writeUTF（字符串str）写入套接字。
