Java中Socket的用法--Spring MVC

package com.test2;

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

public class Server {
    public static void main(String[] args) {

        try {
            //创建一个ServerSocket监听端口8082
            ServerSocket server = new ServerSocket(8082);
            //等待请求
            Socket socket = server.accept();
            //接收到请求后使用socket进行通信，创建BufferedReader用于读取数据
            BufferedReader is = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            String line = is.readLine();
            System.out.println("receivef from client: " + line);
            //创建PrintWriter，用于发送数据
            PrintWriter pw = new PrintWriter(socket.getOutputStream());
            pw.println("receivef data: " + line);
            pw.flush();
            //关闭资源
            pw.close();
            is.close();
            socket.close();
            server.close();
        } catch (Exception e) {
            // TODO: handle exception
        }
    }

}

package com.test2;

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

public class Client {
    public static void main(String[] args) {
        String msg="Client Data";

        try {
            //创建一个Socket监听端口8082
            Socket socket = new Socket("127.0.0.1", 8082);
            //使用Socket创建PrintWriter和BufferedReader进行读写数据
            PrintWriter pw = new PrintWriter(socket.getOutputStream());
            BufferedReader is = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            //发送数据
            pw.println(msg);
            pw.flush();
            //接收数据
            String line = is.readLine();
            System.out.println("received from server: " + line);
            //关闭资源
            pw.close();
            is.close();
            socket.close();
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();
        }
    }
