网站建设的费用和预算互联网广告投放

1、注册百度地图账号

https://lbsyun.baidu.com/apiconsole/key

获取AK(COPY出来，以后要用)

查看百度地图逆地理解析接口文档：

PI服务地址
https://api.map.baidu.com/reverse_geocoding/v3/?ak=您的ak&extensions_poi=1&entire_poi=1&sort_strategy=distance&output=json&coordtype=bd09ll&location=39.951335108535, 116.51484487905
//GET请求

请求地址:

get: https://api.map.baidu.com/reverse_geocoding/v3/

请求参数如下：

key	value
ak:	“PRyu1SQEdG4rihx0RDxxxxxxx”,
output:	“json”,
extensionsPoi:	“1”,
location:	“31.225696563611,121.49884033194”

参数说明：

ak：百度地图 API Key（需要自己申请）

output：输出格式（json/xml）

extensions_poi 是一个 扩展参数，用于返回周边的 POI（兴趣点，Points of Interest） 信息，例如餐馆、商店、学校等。

location：经纬度（格式 lat,lng）

2、编写代码

2.1、添加openfeign依赖

        <dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-openfeign</artifactId></dependency>

2.2、主启动类加注解@EnableFeignClients

@EnableFeignClients
//@EnableDiscoveryClient //核心注解
@SpringBootApplication
public class OrderMainApplication {public static void main(String[] args) {SpringApplication.run(OrderMainApplication.class, args);}
}

2.3、写远程调用的OpenFeign接口

package com.tigerhhzz.order.openfeign;import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;/*** @Author tigerhhzz* @Date 2025 03 25 13 00**/
@FeignClient(value = "baidumap-client",url = "http://api.map.baidu.com")
public interface BaiduMapOpenfeign {@GetMapping("/reverse_geocoding/v3")String getLocationByLonLat(@RequestParam String ak, @RequestParam String output, @RequestParam String extensionsPoi, @RequestParam String location);}

3、测试&响应结果

package com.tigerhhzz.order;import com.tigerhhzz.order.openfeign.BaiduMapOpenfeign;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;/*** @Author tigerhhzz* @Date 2025 03 25 13 07**/
@SpringBootTest
public class BaidumapTest {@AutowiredBaiduMapOpenfeign baiduMapOpenfeign;@Testvoid test01(){String location = baiduMapOpenfeign.getLocationByLonLat("PRyu1SQEdG4rihxxxxxxS8NIcsc", "json", "1", "31.225696563611,121.49884033194");System.out.println(location);}
}

响应结果（包含 POI 信息）：

{"status": 0,"result": {"location": {"lng": 121.49884033193993,"lat": 31.225696429417988},"formatted_address": "上海市黄浦区净土街31弄-4号","edz": {"name": "陆家嘴金融贸易区"},"business": "老西门,城隍庙,西藏南路","business_info": [{"name": "老西门","location": {"lng": 121.49270784559798,"lat": 31.22284211295233},"adcode": 310101,"distance": 0,"direction": "内"},{"name": "城隍庙","location": {"lng": 121.49754405297205,"lat": 31.231853482990294},"adcode": 310101,"distance": 394,"direction": "南"},{"name": "西藏南路","location": {"lng": 121.49155262471214,"lat": 31.219955867050826},"adcode": 310101,"distance": 629,"direction": "东北"}],"addressComponent": {"country": "中国","country_code": 0,"country_code_iso": "CHN","country_code_iso2": "CN","province": "上海市","city": "上海市","city_level": 2,"district": "黄浦区","town": "老西门街道","town_code": "310101019","distance": "58","direction": "北","adcode": "310101","street": "净土街","street_number": "31弄-4号"},"pois": [],"roads": [],"poiRegions": [],"sematic_description": "","formatted_address_poi": "","cityCode": 289}
}

formatted_address：地址信息

pois：POI 兴趣点列表

name：兴趣点名称

addr：兴趣点地址

point：兴趣点坐标

distance：距离查询点的距离（单位：米）

tag：类别（如景点、商场、餐厅等）

4、添加feign日志&注意事项

4.1、添加日志

在配置文件application.yml中添加：

logging:level:com.tigerhhzz.order.openfeign: debug

然后新建如下配置类：

package com.tigerhhzz.order.config;import feign.Logger;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;@Configuration
public class OrderServiceConfig {@Beanpublic RestTemplate restTemplate(){return new RestTemplate();}@BeanLogger.Level feignLoggerLevel(){return Logger.Level.FULL;}
}

日志输出：

4.2、注意事项

在百度地图控制台，相应的api接口中加上发送请求主机的ip白名单；否则会提示如下检验失败的信息：

真正的强大不是忘记，而是接受
