目录

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

1. 注册高德开发者；
2. 去控制台创建应用；
3. 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.ResultCode;
import cn.homed.common.exception.BizException;
import com.alibaba.fastjson.JSONObject;
import lombok.extern.slf4j.Slf4j;
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;

@Slf4j
public class AMAPSearchUtils {

    public static JSONObject getAddressListByKeywords(String keywords, String region,String apiKey,String apiUrl) {
        try {
            HttpClient client = HttpClients.createDefault();
            HttpGet request = new HttpGet(apiUrl + "?key=" + apiKey + "&keywords=" + URLEncoder.encode(keywords,"UTF-8") + "&city_limit=true&region=" + region);
            HttpResponse response = client.execute(request);
            String responseBody = EntityUtils.toString(response.getEntity());
            return JSONObject.parseObject(responseBody);
        } catch (UnsupportedEncodingException uee) {
            log.error("UnsupportedEncodingException 地址搜索失败：{}", uee.getMessage());
            throw new BizException(ResultCode.FAIL, uee.getMessage());
        }catch (IOException io) {
            log.error("IOException 地址搜索失败：{}", io.getMessage());
            throw new BizException(ResultCode.FAIL, io.getMessage());
        }
    }

}

四、运行测试

可以看到，数据也是正常的
