天气预报服务的功能

按照不同的城市来进行查询
查询近几天的天气信息
界面简洁、优雅

天气预报服务的API

获取到该城市ID的天气预报信息：GET/report/cityId/{cityId}

新建项目

复制之前的micro-weather-quartz项目，将副本改名为micro-weather-report

修改源码

修改build.gradle配置，加入thymeleaf的依赖：

//依赖关系
dependencies {

    //该依赖用于编译阶段
	compile('org.springframework.boot:spring-boot-starter-web')
	
	//HttpClient
	compile('org.apache.httpcomponents:httpclient:4.5.6')

    //Redis
    compile('org.springframework.boot:spring-boot-starter-data-redis')

    //Quartz
    compile('org.springframework.boot:spring-boot-starter-quartz')

    //添加Spring Boot Thymeleaf Starter的依赖
    compile('org.springframework.boot:spring-boot-starter-thymeleaf')

    //该依赖用于测试阶段
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

在com.study.spring.cloud.weather.service包下新建接口WeatherReportService：

package com.study.spring.cloud.weather.service;

import com.study.spring.cloud.weather.vo.Weather;

public interface WeatherReportService {

	//根据城市id查询天气信息
	Weather getDataByCityId(String cityId);
}

在com.study.spring.cloud.weather.service包下新建类WeatherReportServiceImpl：

package com.study.spring.cloud.weather.service;

import com.study.spring.cloud.weather.vo.Weather;
import com.study.spring.cloud.weather.vo.WeatherResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class WeatherReportServiceImpl implements WeatherReportService {

	@Autowired
	private WeatherDataService weatherDataService;

	@Override
	public Weather getDataByCityId(String cityId) {
		WeatherResponse resp=weatherDataService.getDataByCityId(cityId);
		return resp.getData();
	}
}

在com.study.spring.cloud.weather.controller包下新建类WeatherReportController：

package com.study.spring.cloud.weather.controller;

import com.study.spring.cloud.weather.service.CityDataService;
import com.study.spring.cloud.weather.service.WeatherReportService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;

@RestController
@RequestMapping("/report")
public class WeatherReportController {
	
	@Autowired
	private CityDataService cityDataService;

	@Autowired
	private WeatherReportService weatherReportService;

	@GetMapping("/cityId/{cityId}")
	//@PathVariable：标识从路径中获取参数
	public ModelAndView getReportByCityId(@PathVariable("cityId") String cityId,Model model) throws Exception {

		model.addAttribute("title", "天气预报");
		model.addAttribute("cityId", cityId);
		model.addAttribute("cityList", cityDataService.listCity());
		model.addAttribute("report", weatherReportService.getDataByCityId(cityId));

		return new ModelAndView("weather/report","reportModel",model);
	}
	
}

修改application.properties配置：

#热部署静态文件
spring.thymeleaf.cache=false

在resources的templates目录下创建weather目录，在weather目录下新建前端页面report.html：

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>天气预报</title>
</head>
<body>
    <h3 th:text="${reportModel.title}">天气</h3>
    <select>
        <option th:each="city : ${reportModel.cityList}"
                th:value="${city.cityId}" th:text="${city.cityName}"
                th:selected="${city.cityId eq reportModel.cityId}"></option>
    </select>
    <h1 th:text="${reportModel.report.city}">城市名称</h1>
    <p>
        空气质量指数：<span th:text="${reportModel.report.aqi}"></span>
    </p>
    <p>
        当前温度：<span th:text="${reportModel.report.wendu}"></span>
    </p>
    <p>
        温馨提示：<span th:text="${reportModel.report.ganmao}"></span>
    </p>

    <div th:each="forecast : ${reportModel.report.forecast}">
        <div>
            <p th:text="${forecast.date}">日期</p>
            <p th:text="${forecast.type}">天气类型</p>
            <p th:text="${forecast.high}">最高温度</p>
            <p th:text="${forecast.low}">最低温度</p>
            <p th:text="${forecast.fengxiang}">风向</p>
        </div>
    </div>
</body>
</html>
