BIO模型

基本模型

代码：

客户端

 package bhz.bio;

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

 public class Client {

     final static String ADDRESS = "127.0.0.1";
     final static int PORT = 8765;

     public static void main(String[] args) {

         Socket socket = null;
         BufferedReader in = null;
         PrintWriter out = null;

         try {
             socket = new Socket(ADDRESS, PORT);
             in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
             out = new PrintWriter(socket.getOutputStream(), true);

             //向服务器端发送数据
             out.println("接收到客户端的请求数据...");
             out.println("接收到客户端的请求数据1111...");
             String response = in.readLine();
             System.out.println("Client: " + response);

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

服务端

 package bhz.bio;

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

 public class Server {

     final static int PROT = 8765;

     public static void main(String[] args) {

         ServerSocket server = null;
         try {
             server = new ServerSocket(PROT);
             System.out.println(" server start .. ");
             //进行阻塞
             Socket socket = server.accept();
             //新建一个线程执行客户端的任务
             new Thread(new ServerHandler(socket)).start();

         } catch (Exception e) {
             e.printStackTrace();
         } finally {
             if(server != null){
                 try {
                     server.close();
                 } catch (IOException e) {
                     e.printStackTrace();
                 }
             }
             server = null;
         }

     }

 }

处理类

package bhz.bio;

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

public class ServerHandler implements Runnable{

    private Socket socket ;

    public ServerHandler(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(true){
                body = in.readLine();
                if(body == null) break;
                System.out.println("Server :" + body);
                out.println("服务器端回送响的应数据.");
            }

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

    }
