[Java语言] Java Socket多线程编程示例

客户端代码如下：

1. import java.io.*;
2. import java.net.*;
3. import java.util.Scanner;
5. public class SimpleChatClient {
6. BufferedReader reader;
7. PrintWriter writer;
8. Socket sock;
9. http://m.nvzi91.cn/fujianyan/29424.html
10. public void go(){
11. System.out.println("客户端启动！");
12. setUpNetworking();
13. //发送数据到服务器
14. Scanner scanner=new Scanner(System.in);
15. String sendString=scanner.nextLine();
16. while(sendString!=null&&!sendString.equals("byebye")){
17. writer.println(sendString);
18. writer.flush();
19. sendString=scanner.nextLine();
20. }
21. scanner.close();
22. System.out.println("客户端退出！");
23. }
25. public void setUpNetworking(){
26. try {
27. sock=new Socket("127.0.0.1",5000);
28. InputStreamReader streamReader=new InputStreamReader(sock.getInputStream());
29. reader=new BufferedReader(streamReader);
30. writer=new PrintWriter(sock.getOutputStream());
31. System.out.println("networking established");
32. } catch (IOException e) {
33. // TODO Auto-generated catch block
34. e.printStackTrace();
35. }http://m.nvzi91.cn/gongjingmilan/29425.html
36. }
39. public static void main(String[] args) {
40. // TODO Auto-generated method stub
41. SimpleChatClient client=new SimpleChatClient();
42. client.go();
43. }
45. }

服务器端代码如下：

1. import java.io.*;
2. import java.net.*;
3. public class SimpleChatServer {
4. //内部类
5. public class ClientHandler implements Runnable{
6. BufferedReader reader;
7. Socket sock;
8. http://m.nvzi91.cn/gongjingmilan/29426.html
9. public ClientHandler(Socket clientSocket){
10. sock=clientSocket;
11. InputStreamReader isReader;
12. try {
13. isReader = new InputStreamReader(sock.getInputStream());
14. reader=new BufferedReader(isReader);
15. } catch (IOException e) {
16. // TODO Auto-generated catch block
17. e.printStackTrace();
18. }
20. }
21. @Override
22. public void run() {
23. // TODO Auto-generated method stub
24. String messageString;
25. try {
26. while((messageString=reader.readLine())!=null){
27. System.out.println("read "+messageString);
28. }
29. } catch (IOException e) {
30. // TODO Auto-generated catch block
31. System.out.println("有一个连接断开");
32. }
33. }
34. /m.nvzi91.cn
35. }
36. public void go(){
37. System.out.println("服务器启动成功！");
38. ServerSocket serverSock;
39. try {
40. serverSock = new ServerSocket(5000);
41. while(true){
42. Socket clientSocket=serverSock.accept();
43. Thread thread=new Thread(new ClientHandler(clientSocket));
44. thread.start();
45. System.out.println("got a connection!");
46. }
47. } catch (IOException e) {
48. // TODO Auto-generated catch block
49. e.printStackTrace();
50. }
52. }
54. public static void main(String[] args) {
55. // TODO Auto-generated method stub
56. new SimpleChatServer().go();
57. }
59. }
