关于socket的简单的客户服务端编程

public class Server { private ServerSocket ss; private Socket socket;// 用来接收客户端的socket private BufferedReader in;// 读取客户端发来的信息 public Server() { try { ss = new ServerSocket(10000); while (true) { System.out.println("等待接收："); socket = ss.accept();// 连接客户端 System.out.println("从" + socket.getRemoteSocketAddress() + "连接成功"); in = new BufferedReader(new InputStreamReader( socket.getInputStream()));// 得到客户端的输入流 String socketText = in.readLine();// 获取客户端的内容 System.out.println(" 客户端说:" + socketText); in.close(); socket.close(); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } /** * @param args */ public static void main(String[] args) { new Server(); }

}

运行结果

先运行服务器显示

等待接收：

然后运行客户端：请输入信息：我爱java

服务器显示：从/127.0.0.1:60139连接成功  客户端说:我爱java
