1.导入hutool的maven依赖

   <dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>5.8.16</version></dependency>

2.直接复制一下代码

import cn.hutool.core.lang.Validator;
public class Test {public static void main(String[] args) throws Exception{String ip = "192.168.0.1";if (Validator.isIpv4(ip) || Validator.isIpv6(ip)) {System.out.println("ip地址正确");}else {System.out.println("ip地址有误");}}
}
