客户端通过socket向服务器端的指定端口发送数据

客户端通过socket向服务器端的指定端口发送数据，最初一直报错：

每当客户端发送数据时，服务器端就报下面的错误：

E:\javacode>java MonitorPort

Exception in thread "main" java.net.SocketException: Connection reset

at java.net.SocketInputStream.read(Unknown Source)

at sun.nio.cs.StreamDecoder.readBytes(Unknown Source)

at sun.nio.cs.StreamDecoder.implRead(Unknown Source)

at sun.nio.cs.StreamDecoder.read(Unknown Source)

at java.io.InputStreamReader.read(Unknown Source)

at java.io.BufferedReader.fill(Unknown Source)

at java.io.BufferedReader.readLine(Unknown Source)

at MonitorPort.main(MonitorPort.

后来经过查找，发现把客户端加上flush和close就好了

MonitorPort .java

import java.io.BufferedReader;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.net.ServerSocket;

import java.net.Socket;

public class MonitorPort {

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

ServerSocket serverSocket = new ServerSocket(80); //监听8800端口

while(true){

Socket socket = serverSocket.accept();//等待客户连接

InputStream socketIn = socket.getInputStream();

BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(socketIn));

String msg = null;

while ((msg=bufferedReader.readLine())!=null) {

System.out.println("接收到信息：" + msg);

}

SendDataToServerPort.java

import java.io.BufferedWriter;

import java.io.IOException;

import java.io.OutputStream;

import java.io.OutputStreamWriter;

import java.net.Socket;

import java.net.UnknownHostException;

public class SendDataToServerPort {

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

Socket socket = new Socket("192.168.10.35",80);

//向服务器端程序发送数据

OutputStream outputStream = socket.getOutputStream();

OutputStreamWriter outputStreamWriter = new OutputStreamWriter(outputStream);

BufferedWriter bufferedWriter = new BufferedWriter(outputStreamWriter);

bufferedWriter.write("hello server, can you receiver my data?");

bufferedWriter.flush();

bufferedWriter.close();

socket.close();

System.out.println("finish send data!!");

}
