二、IpVo

package com.java.vo;import lombok.Data;/*** ip*/
@Data
public class IpVo {private String ip;//IP地址private String pro;//省private String proCode;//省编码private String city;//城市private String cityCode;//城市编码private String region;//区private String regionCode;//区编码private String addr;//详细地址 + 运营商//主要用于接参，无实际意义private String regionNames;private String err;
