Getting error "java.net.SocketException: Connection reset"
提问by Swapnil P.
I am learning Socket Programming in Java. I am getting java.net.SocketException: Connection reset.
我正在学习 Java 套接字编程。我得到java.net.SocketException: Connection reset.
Client Side Code
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);
}
}
Here is my console after run client code, I am getting Exception Connection reset, where I am doing wrong?
这是运行客户端代码后的控制台，我正在重置异常连接，我做错了什么？

"Exception in thread "main" java.net.SocketException: Connection reset" error occurs when the opponent is forcibly terminated without calling close().
“线程“main”中的异常java.net.SocketException: Connection reset”是在没有调用close()的情况下强行终止对方时出现的错误。
Add this line to ClientSock
将此行添加到 ClientSock
skt.close();
and I recommend this too to ServerSock.
我也向 ServerSock 推荐这个。
ss.close();
java.io.Closeable implementing object must call close ().
java.io.Closeable 实现对象必须调用close()。

You forgot "\n" in your "Hello Server".
Reader can't get the full line and throws this exception.
您在“Hello Server”中忘记了“\n”。
Reader 无法获取完整行并抛出此异常。
