Java获取本地MAC地址、IP、主机名

这里引用了hutool的NetUtil工具类
废话不多说，直接贴代码

package com.rh.rhproducer.controller;

import cn.hutool.core.net.NetUtil;

import java.net.InetAddress;
import java.net.UnknownHostException;

public class HostTest {

public static void main(String[] args) throws UnknownHostException{//获取本地mac地址String macAddress = NetUtil.getMacAddress(InetAddress.getLocalHost());System.out.println(macAddress);//获取本地ip和主机名InetAddress addr = InetAddress.getLocalHost();System.out.println("IP地址：" + addr.getHostAddress() + "，主机名：" + addr.getHostName());}

}
控制台打印出：

5c-3a-45-02-8a-11
IP地址：192.168.2.24，主机名：WIN-PUHUHRP6UU9

进程已结束，退出代码 0
