Question

我正在学习Java中的Socket编程。我得到了java.net.SocketException: Connection reset。

客户端代码

    package com.socket;

    import java.io.OutputStreamWriter;
    import java.io.PrintWriter;
    import java.net.Socket;

    public class ClientSock {

        public static void main(String[] args) throws Exception {

            Socket skt = new Socket("localhost", 8888);     
            String str = "Hello Server";
            OutputStreamWriter osw = new OutputStreamWriter(skt.getOutputStream()); 

            PrintWriter out = new PrintWriter(osw);
            osw.write(str);
            osw.flush();        
        }
    }

//Server Side Code:

    package com.socket;

    import java.io.BufferedReader;
    import java.io.InputStreamReader;
    import java.net.ServerSocket;
    import java.net.Socket;

    public class ServerSock {

        public static void main(String[] args) throws Exception {

            System.out.println("Server is Started");
            ServerSocket ss = new ServerSocket(8888);

            Socket s = ss.accept();

            BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));
            String str = br.readLine();

            System.out.println("Client Says : " + str);         
        }
    }

这是运行客户端代码后我的控制台，我正在重置异常连接，我做错了吗？

Answer 1

＆＃34;线程中的异常＆＃34; main＆＃34; java.net.SocketException：连接重置＆＃34;当对手被强行终止而没有调用close（）时会发生错误。

将此行添加到ClientSock

skt.close();

我也向ServerSock推荐这个。

ss.close();

java.io.Closeable实现对象必须调用close（）。

Answer 2

你忘了＆＃34; \ n＆＃34;在您的＆＃34; Hello Server＆＃34;。
读者无法获得整行并抛出此异常。

得到错误＆＃34; java.net.SocketException：连接重置＆＃34;
