如何在Java中获取客户登录的IP地址并获取物理地址

1. 流程图

stateDiagram
    [*] --> 获取IP地址
    获取IP地址 --> 获取物理地址
    获取物理地址 --> 结束

2. 步骤

步骤	操作	代码示例
1	获取IP地址	`InetAddress IP = InetAddress.getLocalHost();`
2	获取物理地址	`NetworkInterface network = NetworkInterface.getByInetAddress(IP);`

3. 代码实现

import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;

public class IPAddressExample {

    public static void main(String[] args) {
        try {
            // 获取IP地址
            InetAddress IP = InetAddress.getLocalHost();
            System.out.println("IP地址: " + IP.getHostAddress());

            // 获取物理地址
            NetworkInterface network = NetworkInterface.getByInetAddress(IP);
            byte[] physicalAddress = network.getHardwareAddress();
            StringBuilder sb = new StringBuilder();
            for (int i = 0; i < physicalAddress.length; i++) {
                sb.append(String.format("%02X%s", physicalAddress[i], (i < physicalAddress.length - 1) ? "-" : ""));
            }
            System.out.println("物理地址: " + sb.toString());
        } catch (UnknownHostException e) {
            e.printStackTrace();
        } catch (SocketException e) {
            e.printStackTrace();
        }
    }
}
