简单BioDemo示例（socket通信）

思路：服务端接到请求，分发给多线程任务，返回时间给客户端

 

Bioserver服务端

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

public class BioServer {

    /**
     * 端口号
     */
    private static final int PORT = 8080;

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

        ServerSocket server = null;
        try {
            server = new ServerSocket(PORT);
            System.out.println("the time server is start in port : " + PORT);

            Socket socket = null;

            while (true){
                socket = server.accept();
                new Thread(new TimeServerHandler(socket)).start();
            }


        }catch (Exception e){
            e.printStackTrace();
        }finally {
            if(server!=null){
                System.out.println("the time server close");
                server.close();
            }
        }
    }
}

 

多线程时间任务

import java.io.*;
import java.net.Socket;
import java.util.Date;

public class TimeServerHandler implements Runnable {

    private Socket socket;

    public TimeServerHandler(Socket socket){
        this.socket = socket;
    }


    @Override
    public void run() {
        BufferedReader in = null;
        PrintWriter out = null;

        try {

            in = new BufferedReader(new InputStreamReader(this.socket.getInputStream())) ;
            out = new PrintWriter(this.socket.getOutputStream(), true);

            String body = null;

            while ((body = in.readLine())!=null && body.length()!=0){
                System.out.println("the time server receive msg :" + body);
                out.println(new Date().toString());
            }

        }catch (Exception e){
            e.printStackTrace();
        }finally {

            if(in!=null){
                try {
                    in.close();
                }catch (Exception e){
                    e.printStackTrace();
                }
            }
            if(out!=null){
                try {
                    out.close();
                }catch (Exception e){
                    e.printStackTrace();
                }
            }
            if(this.socket != null){
                try{
                    this.socket.close();

                }catch (Exception e){
                    e.printStackTrace();
                }
            }

        }
    }
}

 

BioCenlit客户端

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

public class BioClient {

    private static final int PORT = 8080;
    private static final String HOST = "127.0.0.1";

    public static void main(String[] args){
        Socket socket = null;
        BufferedReader in = null;
        PrintWriter out = null;

        try {
            socket = new Socket(HOST, PORT);
            in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            out = new PrintWriter(socket.getOutputStream(), true);
            out.println("I am Client");
            String resp = in.readLine();
            System.out.println("当前服务器时间是:"+resp);

        }catch (Exception e){
            e.printStackTrace();
        }finally {
            if(in != null){
                try {
                    in.close();
                }catch (Exception e){
                    e.printStackTrace();
                }
            }
            if(out != null){
                try {
                    out.close();
                }catch (Exception e){
                    e.printStackTrace();
                }
            }
            if (socket != null) {
                try {
                    socket.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
    }
