需要依赖

<dependency>
    <groupId>com.baidubce</groupId>
    <artifactId>api-explorer-sdk</artifactId>
    <version>1.0.0</version>
</dependency>

代码如下：

工具类：

import com.baidubce.http.ApiExplorerClient;
import com.baidubce.http.AppSigner;
import com.baidubce.http.HttpMethodName;
import com.baidubce.model.ApiExplorerRequest;
import com.baidubce.model.ApiExplorerResponse;
import com.baidubce.model.ApiExplorerResponseMetadata;

public class Iputils {
    public static String getCityInformation(String ip, String AccessKey, String AppSecret) {
        String path = "http://ipapi.api.bdymkt.com/ip2location/retrieve";
        ApiExplorerRequest request = new ApiExplorerRequest(HttpMethodName.POST, path);
        request.setCredentials(AccessKey, AppSecret);
        request.addHeaderParameter("Content-Type", "application/json;charset=UTF-8");
        String requestExample = "{\n  \"ip\": \"" + ip + "\"\n}";
        request.setJsonBody(requestExample);
        ApiExplorerClient client = new ApiExplorerClient(new AppSigner());
        try {
            ApiExplorerResponse response = client.sendRequest(request);
            // 返回结果格式为Json字符串
            String result = response.getResult();
            return result;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return "获取失败!!!!!!!";
    }

}

测试：

import com.alibaba.fastjson.JSON;
import com.financial.sys.domain.ipDto;
import com.financial.sys.utils.Iputils;

public class getip {
    public static void main(String[] args) {
        String city = Iputils.getCityInformation("请输入ip地址", "你的AccessKey", "你的AppSecret");
        ipDto ipDto = JSON.parseObject(city, ipDto.class);
        System.out.println("城市是："+ipDto.getCountry());
        System.out.println("省是："+ipDto.getProvince());
        System.out.println("城市是："+ipDto.getCity());
        System.out.println("县是："+ipDto.getCounty());
        System.out.println("提供商是："+ipDto.getIsp());
    }
}

自己封装实体类！
