Connection reset by peer: socket write error
小弟最近练习Java socket tcp这部分.出了点问题。客户端给服务器发送信息。第一次服务器可以收到，但是客户端第二次发送，就报异常了：Exception in thread "main" java.net.SocketException: Connection reset by peer: socket write error具体代码如下：
Server.java
import java.io.BufferedReader;
import java.io.DataInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;
public class Server {
private ServerSocket sskt=null;
public static final int port=9999;
public ServerSocket getSskt() {
return sskt;
}
public Server() {
try {
sskt=new ServerSocket(9999);
System.out.println("服务器启动成功..."+"端口号："+port);
} catch (IOException e) {
e.printStackTrace();
}
}
public Socket acceptSkt() throws IOException{
Socket skt=null;
skt=getSskt().accept();
System.out.println("一个客户端程序已连接."+"clientInfo:"+skt.getInetAddress().getHostAddress()+"-->"+skt.getPort());
return skt;
}
public String readMsg(Socket skt) throws IOException{
InputStream ins=skt.getInputStream();
DataInputStream dis=new DataInputStream(ins);
String msg= dis.readUTF();
System.out.println("客户端发来的信息:"+msg);
return msg;
}
public static void main(String[] args) throws IOException{
Server server=new Server();
Socket skt= server.acceptSkt();
String msg=server.readMsg(skt);
}
}
client.java
import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.Socket;
import java.net.UnknownHostException;
public class Client {
public static final String host = "127.0.0.1";
public static final int port = 9999;
private Socket skt = null;
private DataOutputStream dos = null;
public DataOutputStream getDos() {
return dos;
}
public Client() {
try {
skt = new Socket(host, port);
dos = new DataOutputStream(skt.getOutputStream());
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
public String getMsgFrmConsole() throws IOException {
System.out.print("请输入:");
BufferedReader bufReader = new BufferedReader(new InputStreamReader(
System.in));
String msg = null;
msg = bufReader.readLine();
return msg;
}
public void sendmsg(String msg) throws IOException {
getDos().writeUTF(msg);
getDos().flush();
}
public String reviceMsg() throws IOException {
return null;
}
public static void main(String[] args) throws UnknownHostException,
IOException {
Client client = new Client();
while (true) {
String msg = client.getMsgFrmConsole();
client.sendmsg(msg);
}
}
}
在此感谢大家的帮助了
java net socket 异常 --------------------编程问答-------------------- 异常出现在客户端.... --------------------编程问答-------------------- 这是个烦人的报错 是哪一行开始出错的呢 --------------------编程问答-------------------- 除 --------------------编程问答-------------------- getDos().writeUTF(msg);这一句。不过，我已经解决了这个异常。问题出在服务器上。客户端第二次给服务器发送信息的时候。服务器这边没有再次读取信息。所以，客户端在第二次发送信息的时候就出错了。解决方法是：在服务器端加入如下代码即可：
while(true){
String msg=server.readMsg(skt);
if(msg.equals("bye")){
System.out.println("客户端退出！");
break;
}
} --------------------编程问答-------------------- 客户端不停的发送信息，服务器端不停的的读取信息。两边都要一个循环。
