简单的socket通讯学习,1对1聊天
?
1:简单介绍Socket和ServerSocket的通信，如下，注意客户端和服务是怎么交换数据的
?

1:客户端代码
import java.io.DataInputStream;import java.io.DataOutputStream;import java.io.IOException;import java.net.Socket;import java.util.Scanner;public class Client {private static int port = 12315; // 端口private static String address = "localhost";public void chat() throws IOException {try {Socket socket = new Socket(address, port); // 连接到服务器.try {// 获得从服务端发送过来的信息DataInputStream din = new DataInputStream(socket.getInputStream());// 声明想发送到服务器的输出流DataOutputStream dout = new DataOutputStream(socket.getOutputStream());Scanner scan = new Scanner(System.in); // 获得客户端输入的信息while (true) {String sendMsg = scan.nextLine();if (!"".equals(sendMsg)) {System.out.println("****客户端: " + sendMsg+ " ");dout.writeUTF(sendMsg);String recvMsg = din.readUTF();if (null != recvMsg) {System.out.println("***服务端: " + recvMsg+ " ");}}}} finally {socket.close();}} finally {}}public static void main(String[] aregs) throws IOException{new Client().chat();}}?

2: 服务端代码
?
import java.io.DataInputStream;import java.io.DataOutputStream;import java.net.ServerSocket;import java.net.Socket;import java.util.Scanner;public class HostServer {private static int port = 12315;public void service(){try{ServerSocket server = new ServerSocket(port); //建立服务器连接Socket socket = server.accept(); //等待客户端连接try{DataInputStream din = new DataInputStream(socket.getInputStream()); //获得客户端输入流DataOutputStream dout = new DataOutputStream(socket.getOutputStream()); //取得输出流Scanner scan = new Scanner(System.in);while(true){String recvMsg = din.readUTF(); //获得客户端发送的信息System.out.println("------客户端:" + recvMsg);String sendMsg = scan.nextLine();System.out.println("------服务端:" + sendMsg);dout.writeUTF(sendMsg); //将从控制台读取的数据发送给客户端}}finally{socket.close();}}catch (Exception e) {}}public static void main(String[] args){new HostServer().service();}}?

先运行HostServer,在运行Client,
这个程序满足1对1的信息交互，
