使用Springboot实现获取某个城市当天的天气预报
作者:星空下夜猫子
这篇文章主要为大家详细介绍了使用Springboot实现获取某个城市当天的天气预报的相关知识,感兴趣的小伙伴可以跟随小编一起学习一下
获取天气信息作者是通过高德开放平台来实现的。
1、在该平台注册个账号
如已经注册,直接登录即可。
2、创建应用
创建成功后获取到key值。(注意该值会经常用到,且可以共用保存好)
3、进入开发文档选择天气查询
下面按照说明使用即可。
接下来上代码。(注意功能接受的是JSON格式的)
4、pom.xml文件的引用
<dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.80</version> </dependency>
5、配置文件
无
6、实体类
package com.zjh.weixin.Model; import lombok.Data; import java.util.List; /** * @Author: zjh * @Date: 2022/9/19 11:03 * @Description: 天气总实体 * @Version: v1.0 */ @Data public class WeatherModel { private String status; private String count; private String nfo; private String infocode; private List<LivesModel> lives; }
该实体为总实体(后续添加功能时,在总实体添加引用,在创建子实体)
package com.zjh.weixin.Model; import lombok.Data; /** * @Author zjh * @Date 2022/9/19 1053 * @Description 天气实体类 * @Version v1.0 */ @Data public class LivesModel { private String province; private String city; private String adcode; private String weather ; private String temperature ; private String winddirection; private String windpower; private String humidity; private String reporttime ; }
该类为子实体
7、根据路径获取信息
package com.zjh.weixin.Util; import org.springframework.http.HttpEntity; import org.springframework.http.HttpHeaders; import org.springframework.http.MediaType; import org.springframework.web.client.RestTemplate; import com.alibaba.fastjson.JSON; import java.util.Map; /** * @Author: zjh * @Date: 2022/9/19 10:29 * @Description: 后端根据路径发起请求 * @Version: v1.0 */ public class HttpsUtil { /** * get请求 */ public static String get(String url){ HttpHeaders headers = new HttpHeaders(); MediaType mediaType = MediaType.parseMediaType("application/json; charset=UTF-8"); headers.setContentType(mediaType); RestTemplate restTemplate = new RestTemplate(); String result = restTemplate.getForObject(url, String.class); return result; } }
8、调用方法
public static void main(String[] args) { String url = "https://restapi.amap.com/v3/weather/weatherInfo?city=411400&key=b2f301************077d21"; String s = HttpsUtil.get(url); System.out.println(s); JSONObject object = JSONObject.parseObject(s); WeatherModel jb = (WeatherModel)JSONObject.toJavaObject(object, WeatherModel.class); System.out.println(jb); LivesModel livesModel = jb.getLives().get(0); System.out.println(livesModel); int c =Integer.valueOf(livesModel.getTemperature()); SimpleDateFormat dateFm = new SimpleDateFormat("EEEE"); String currSun = dateFm.format(new Date()); String r = null; if (c<=26 && c>=18){ r="今天温度适宜"; }else if (c>26){ r="今天温度较高,注意防晒"; }else if(c<18){ r="今天温度较低,注意保暖"; } String zong = "日期: "+livesModel.getReporttime()+" "+currSun+"\n"+ "所在城市: "+livesModel.getCity()+"\n"+ "天气: " + livesModel.getWeather()+"\n"+ "温度: "+ livesModel.getTemperature()+" "+r+"\n"+ "风向: "+ livesModel.getWinddirection()+"风"+"\n"+ "风级: "+livesModel.getWindpower(); System.out.println(zong); }
成功返回数据
9、项目优化
public static String getWeather(String adcode,String key){ String url = "https://restapi.amap.com/v3/weather/weatherInfo?city="+adcode+"&key="+key; String s = HttpsUtil.get(url); JSONObject object = JSONObject.parseObject(s); WeatherModel jb = (WeatherModel)JSONObject.toJavaObject(object, WeatherModel.class); LivesModel livesModel = jb.getLives().get(0); int c =Integer.valueOf(livesModel.getTemperature()); SimpleDateFormat dateFm = new SimpleDateFormat("EEEE"); String currSun = dateFm.format(new Date()); String r = null; if (c<=26 && c>=18){ r="今天温度适宜"; }else if (c>26){ r="今天温度较高,注意防晒"; }else if(c<18){ r="今天温度较低,注意保暖"; } String zong = "日期: "+livesModel.getReporttime()+" "+currSun+"\n"+ "所在城市: "+livesModel.getCity()+"\n"+ "天气: " + livesModel.getWeather()+"\n"+ "温度: "+ livesModel.getTemperature()+" "+r+"\n"+ "风向: "+ livesModel.getWinddirection()+"风"+"\n"+ "风级: "+livesModel.getWindpower(); return zong; } private static String getCityCode(String adress,String key){ String url = "https://restapi.amap.com/v3/geocode/geo?address="+adress+"&key="+key; String s = HttpsUtil.get(url); JSONObject object = JSONObject.parseObject(s); System.out.println(object); JSONArray array = (JSONArray) object.get("geocodes"); JSONObject arrayObject = (JSONObject) array.get(0); String adcode = arrayObject.get("adcode").toString(); return adcode; } public static void main(String[] args) { System.out.println(getCityCode("河南省郑州市","b2f301c36******77d21")); System.out.println(getWeather(getCityCode("河南省郑州市","b2f3*****7d21"),"b2f3*******7d21")); }
注:该功能虽说是springboot项目,但是缺失许多东西,不太完善(其主要原因是因为作者发现通过java编程实现通过用户账号发送给该用户的好友信息,只能通过Robot的自动测试功能实现微信发送消息。该方法缺点太大,不太方便,暂时未找到其他更好的方法
