Java对接高德api搜索POI 2.0 关键字搜索

一、注册账号

二、搜索小demo

1.首先要引入依赖

2. 然后查看打印结果即可

三、搜索接口代码

1.引入依赖

2.yml配置

2.Controller

3.静态工具类

四、运行测试

一、注册账号

高德开放平台 | 高德地图API

注册高德开发者；
去控制台创建应用；
获取Key；

具体教程可以看官方文档创建应用和 Key-Web服务 API | 高德地图API，api文档也在链接里

二、搜索小demo

我这里用到的是关键字搜索，先写个小demo测试一下

1.首先要引入依赖

引入这个依赖主要是因为我们是通过HttpClient类来发送HTTP请求并获取响应的

<dependencies><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.13</version></dependency>
</dependencies>

2. 然后查看打印结果即可

package cn.homed.aio.device.web;import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;public class gaode {public static void main(String[] args) throws UnsupportedEncodingException {HttpClient client = HttpClients.createDefault();String apiUrl = "https://restapi.amap.com/v5/place/text";String apiKey = "这里填你申请的key";String searchTest = "天安门广场";HttpGet request = new HttpGet(apiUrl + "?key=" + apiKey + "&keywords=" + URLEncoder.encode(searchTest,"UTF-8"));try {HttpResponse response = client.execute(request);String responseBody = EntityUtils.toString(response.getEntity());System.out.println(responseBody);} catch (IOException e) {e.printStackTrace();}}
}

三、搜索接口代码

1.引入依赖

使用Fastjson的JSONObject类来解析HTTP响应的JSON格式数据。这样做的好处是可以方便地将HTTP响应中的JSON数据转换为Java对象

<dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.78</version>
</dependency>

2.yml配置

2.Controller

这里的入参keywords是关键字，region是搜索区划

package cn.homed.common.webchat;import cn.homed.common.constant.CommonKey;
import cn.homed.common.entity.MsgBean;
import cn.homed.common.utils.StringUtil;
import com.alibaba.fastjson.JSONObject;
import io.swagger.v3.oas.annotations.Operation;
import io.swagger.v3.oas.annotations.tags.Tag;
import lombok.extern.slf4j.Slf4j;
import org.apache.http.HttpEntity;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;/*** @author hulongtao*/
@Slf4j
@RestController
@Tag(name ="高德搜索", description = "高德搜索接口")
@RequestMapping("/api/amap/getAddressList")
public class AutonaviSearchController {@Value("${AMAP.apiKey}")private String apiKey;@Value("${AMAP.apiUrl}")private String apiUrl;@Operation(summary = "地址搜索", description = "通用搜索")@PostMapping(value = "")public MsgBean getAddressList(@RequestParam(value = "keywords") String keywords , @RequestParam(value = "region",required = false) String region) {if (StringUtil.isNotNullOrEmpty(keywords)) {try {JSONObject addressListByKeywords = AMAPSearchUtils.getAddressListByKeywords(keywords, region,apiKey,apiUrl);if (CommonKey.CONSTANT_1.equals(addressListByKeywords.getString("status"))) {return MsgBean.success(addressListByKeywords.getJSONArray("pois"),"搜索成功");}return MsgBean.failMsg("搜索异常");}catch (Exception e){log.error("搜索地址失败:{}",e.getMessage());return MsgBean.fail(CommonKey.FAIL);}}return MsgBean.success();}
}

3.静态工具类

这里的city_limit返回限制

package cn.homed.common.webchat;import cn.homed.common.constant.CommonKey;
import cn.homed.common.entity.MsgBean;
import cn.homed.common.utils.StringUtil;
import com.alibaba.fastjson.JSONObject;
import io.swagger.v3.oas.annotations.Operation;
import io.swagger.v3.oas.annotations.tags.Tag;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;/*** @author hulongtao*/
@Slf4j
@RestController
@Tag(name ="高德搜索", description = "高德搜索接口")
@RequestMapping("/api/amap/getAddressList")
public class AutonaviSearchController {@Value("${AMAP.apiKey}")private String apiKey;@Value("${AMAP.apiUrl}")private String apiUrl;@Operation(summary = "地址搜索", description = "通用搜索")@PostMapping(value = "")public MsgBean getAddressList(@RequestParam(value = "keywords") String keywords , @RequestParam(value = "region",required = false) String region) {if (StringUtil.isNotNullOrEmpty(keywords)) {try {JSONObject addressListByKeywords = AMAPSearchUtils.getAddressListByKeywords(keywords, region,apiKey,apiUrl);if (CommonKey.CONSTANT_1.equals(addressListByKeywords.getString("status"))) {return MsgBean.success(addressListByKeywords.getJSONArray("pois"),"搜索成功");}return MsgBean.failMsg("搜索异常");}catch (Exception e){log.error("搜索地址失败:{}",e.getMessage());return MsgBean.fail(CommonKey.FAIL);}}return MsgBean.success();}
}
