前言
用ServerSocket和Socket做了个Server、Client通信的demo，以及学习下在这个demo过程中用到java.net、java.io包下几个常用的类。
Server
import java.net.*;import java.io.*;public class HttpServer{
public static void main(String[] args){ new HttpServer().start();
}
private ServerSocket serversocket=null;
public HttpServer(){ try{
serversocket=new ServerSocket(5000);//监听客户端端口5000的socket请求
System.out.println("服务器启动");
}catch(IOException e){
e.printStackTrace();
}
} public void start(){
Socket socket=null; while(true){ try{
socket=serversocket.accept(); //接受客户端请求socket
System.out.println("address:"+socket.getInetAddress()+":"+socket.getLocalPort());
OutputStream os =socket.getOutputStream();
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(os)); //向客户端发送一条消息
bw.write("测试服务器通信\n");
bw.flush();
}catch(IOException e){
e.printStackTrace();
System.out.println("连接断开");
}finally{ try{ if(socket !=null){
socket.close();
}
}catch(IOException e){
}
}
}
}
}
Client
import java.net.*;import java.io.*;public class Client{
public static void main(String[] args){
Socket socket=null; try{
socket =new Socket("127.0.0.1",5000);
InputStream is =socket.getInputStream();
InputStreamReader isr=new InputStreamReader(is);
BufferedReader br =new BufferedReader (isr);
String mess=br.readLine();
System.out.println("mess:"+mess);
}catch(IOException e){
e.printStackTrace();
}finally{ try{ if(socket !=null){
socket.close();
}
}catch(IOException e){
}
}
}
}
总结
java.net包内几个常用的类:
ServerSocket、
Socket、
OutputStream、InputStream、
InputStreamReader、OutputStreamWriter、
BufferedReader、BufferedWriter、
InetAddress、
