Java 实例- ServerSocket 和 Socket 通信实例

import java.io.BufferedReader; import java.io.BufferedWriter; import java.io.IOException; import java.io.InputStreamReader; import java.io.OutputStreamWriter; import java.net.ServerSocket; import java.net.Socket; public class Server { public static void main(String[] args) { try { ServerSocket ss = new ServerSocket(8888); System.out.println("启动服务器...."); Socket s = ss.accept(); System.out.println("客户端:"+s.getInetAddress().getLocalHost()+"已连接到服务器"); BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream())); //读取客户端发送来的消息 String mess = br.readLine(); System.out.println("客户端："+mess); BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(s.getOutputStream())); bw.write(mess+"\n"); bw.flush(); } catch (IOException e) { e.printStackTrace(); } } }

以上代码运行输出结果为：

启动服务器....

2、建立客户端

创建Socket通信，设置通信服务器的IP和Port
建立IO输出流向服务器发送数据消息
建立IO输入流读取服务器发送来的数据消息

客户端代码:

Client.java 文件

import java.io.BufferedReader; import java.io.BufferedWriter; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.io.OutputStream; import java.io.OutputStreamWriter; import java.net.Socket; import java.net.UnknownHostException; public class Client { public static void main(String[] args) { try { Socket s = new Socket("127.0.0.1",8888); //构建IO InputStream is = s.getInputStream(); OutputStream os = s.getOutputStream(); BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(os)); //向服务器端发送一条消息 bw.write("测试客户端和服务器通信，服务器接收到消息返回到客户端\n"); bw.flush(); //读取服务器返回的消息 BufferedReader br = new BufferedReader(new InputStreamReader(is)); String mess = br.readLine(); System.out.println("服务器："+mess); } catch (UnknownHostException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } }

以上代码运行输出结果为：

服务器：测试客户端和服务器通信，服务器接收到消息返回到客户端
