最近有個需求，需要輸入上車點，下車點，然后輸入上車點的時候還要在下方顯示地圖附近的車輛。百度了一波之后，完全莫得頭緒，很多代碼也都用不了，即便改了之后也不怎么生效。我用的是jeecg-boot.最后靜下心，還是老老實實的調用api接口請求數據，完成了這個需求。效果如下：
1.剛點開彈框時：
2.當輸入上車地點的時候，提示對應的地址，以及詳細地址
3.當選中了地址后，顯示地圖，並定位到選擇的位置，同時顯示附近車輛
4.選擇下車點，同理，不過下車點不會彈地圖，沒有地圖操作，單純的一個關鍵字搜索操作
下面說說具體的實現過程。前提說明，涉及到前后端代碼聯動。
前端方面：
我就直接丟代碼了：首先是我這個彈窗的代碼：

import Vue from 'vue'

對，沒錯，只有這兩行。
剩下的就是后台java的操作了，相關代碼如下：
controller：
在對應的controller添加這么一個接口
/**
* 根據關鍵字查詢地理信息
*
* @param keyword
* @return
*/
@AutoLog(value = "訂單管理-根據關鍵字查詢地理信息")
@ApiOperation(value="訂單管理-根據關鍵字查詢地理信息", notes="訂單管理-根據關鍵字查詢地理信息")
@GetMapping(value = "/getAddressItem")
public Result<?> getAddressItem(@RequestParam(name="keyword",required=true) String keyword) {
List<AddressVo> addressVoList = orderService.getAddressItem(keyword);
return Result.ok(addressVoList);
}
新建AddressVo類
import lombok.Data;
@Data
public class AddressVo {
private String name;
private String pname;
private String cityname;
private String adname;
private String address;
private String location;
}
然后是對應的service實現，我寫的比較糟糕，你們用的時候可以適當改進一下：
@Override
public List<AddressVo> getAddressItem(String keyword) {
String parameter = "key="+key+"&"+"keywords="+keyword+"&offset=15&city=廣州";
String result = HttpRequest.sendGet("https://restapi.amap.com/v3/place/text", parameter);
Map<String, Object> map = new HashMap<String, Object>();
Gson gson = new Gson();
map = gson.fromJson(result, map.getClass());
Object pois = map.get("pois");
List<AddressVo> list = JSON.parseArray(JSON.toJSONString(pois), AddressVo.class);
return list;
}
沒有的依賴可以引入對應的pom依賴。
另外涉及到一個請求發送的工具包
HttpRequest.java
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
