服务器端
package socket_util;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.net.InetSocketAddress;import java.net.ServerSocket;import java.net.Socket;public class Server { public void run() throws IOException{ //服务端socket对象 ServerSocket serverSocket = new ServerSocket(); serverSocket.bind(new InetSocketAddress("127.0.0.1",1234)); while(true) { Socket socket = serverSocket.accept(); //接收客户端发来的数据 InputStream is = socket.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); String str = null; if( (str = br.readLine()) != null) { System.out.println(str); } socket.close(); } } public static void main(String[] args) { Server s = new Server(); System.out.println("服务器端开启"); try { s.run(); } catch (IOException e) { System.out.println("IO异常"); e.printStackTrace(); } }}客户端
package socket_util;import java.io.IOException;import java.net.Socket;public class Client { public void send(String data) throws IOException { //创建socket对象，指定ip、port Socket socket = new Socket("127.0.0.1", 1234); //将数据传到输出管道字节流发送到服务器端 socket.getOutputStream().write(data.getBytes()); //清空IO管道重的缓存数据 socket.getOutputStream().flush(); socket.close(); } public static void main(String[] args) { Client c = new Client(); try { c.send("123456789,nimabinijiehunlema"); System.out.println("发送成功"); } catch (IOException e) { System.out.println("IO异常"); e.printStackTrace(); } }}扫描服务器端是否开启
package socket_util;import java.io.IOException;import java.net.InetSocketAddress;import java.net.Socket;import java.net.SocketAddress;/* * 必须在服务器端开启的时候才能扫描成功 */public class ScanPorts { private int minPort, maxPort; public ScanPorts(int minPort, int maxPort) { this.minPort = minPort; this.maxPort = maxPort; } public void run() throws IOException { for(int i = minPort; i <= maxPort; i++) { Socket socket = new Socket(); SocketAddress socketAddress = new InetSocketAddress("127.0.0.1", i); socket.connect(socketAddress, 50); System.out.println(i + ":ok"); socket.close(); } } public static void main(String[] args) { ScanPorts sc = new ScanPorts(1234, 1234); try { sc.run(); } catch (IOException e) { e.printStackTrace(); } }}运行结果截图
运行服务器端Server.java
运行扫描端ScanPorts.java
运行服务器端Client.java
这是打开之前服务器端的控制台输出，会显示发送来的数据
