创建项目

新建项目文件夹：
Spring Cloud学习笔记10——天气预报系统微服务（4）天气预报微服务
将micro-weather-report项目中的源码文件复制粘贴到新项目文件夹中：

修改源码

修改build.gradle配置，删除HttpClient、redis、quartz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')

    //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')
}

修改com.study.spring.cloud.weather.service包下的WeatherReportServiceImpl类：

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

import com.study.spring.cloud.weather.vo.Forecast;
import com.study.spring.cloud.weather.vo.Weather;
import org.springframework.stereotype.Service;

import java.util.ArrayList;
import java.util.List;

@Service
public class WeatherReportServiceImpl implements WeatherReportService {

	@Override
	public Weather getDataByCityId(String cityId) {
		//TODO 改为由天气数据API微服务来提供数据
		Weather data=new Weather();
		data.setAqi("81");
		data.setCity("上海");
		data.setGanmao("容易感冒！多穿衣");
		data.setWendu("16");

		List<Forecast> forecastList=new ArrayList<>();

		Forecast forecast=new Forecast();
		forecast.setDate("13日星期一");
		forecast.setFengli("<![CDATA[<3级]]>");
		forecast.setFengxiang("西南风");
		forecast.setHigh("18");
		forecast.setLow("12");
		forecast.setType("阴");

		forecastList.add(forecast);

		forecast=new Forecast();
		forecast.setDate("14日星期二");
		forecast.setFengli("<![CDATA[<3级]]>");
		forecast.setFengxiang("西南风");
		forecast.setHigh("18");
		forecast.setLow("12");
		forecast.setType("阴");

		forecastList.add(forecast);

		forecast=new Forecast();
		forecast.setDate("15日星期三");
		forecast.setFengli("<![CDATA[<3级]]>");
		forecast.setFengxiang("西南风");
		forecast.setHigh("18");
		forecast.setLow("12");
		forecast.setType("阴");

		forecastList.add(forecast);

		forecast=new Forecast();
		forecast.setDate("16日星期四");
		forecast.setFengli("<![CDATA[<3级]]>");
		forecast.setFengxiang("西南风");
		forecast.setHigh("18");
		forecast.setLow("12");
		forecast.setType("阴");

		forecastList.add(forecast);

		forecast=new Forecast();
		forecast.setDate("17日星期五");
		forecast.setFengli("<![CDATA[<3级]]>");
		forecast.setFengxiang("西南风");
		forecast.setHigh("18");
		forecast.setLow("12");
		forecast.setType("阴");

		forecastList.add(forecast);

		data.setForecast(forecastList);

		return data;
	}
}

修改com.study.spring.cloud.weather.controller包下的WeatherReportController类：

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

import com.study.spring.cloud.weather.service.WeatherReportService;
import com.study.spring.cloud.weather.vo.City;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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;

import java.util.ArrayList;
import java.util.List;

@RestController
@RequestMapping("/report")
public class WeatherReportController {

	//在应用中添加日志
	private final static Logger logger=LoggerFactory.getLogger(WeatherReportController.class);

	@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 {

		//获取城市列表
		//TODO 改为由城市数据API微服务来提供数据
		List<City> cityList=null;

		try {
			//TODO 改为由城市数据API微服务来提供数据
			cityList = new ArrayList<>();
			City city=new City();
			city.setCityId("101020100");
			city.setCityName("上海");
			cityList.add(city);

		} catch (Exception e) {
			logger.error("Exception!",e);
		}

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

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

修改com.study.spring.cloud.weather.vo包下的City类，去掉其中xml相关解析代码：

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

public class City {

	private String cityId;

	private String cityName;

	private String cityCode;

	private String province;

	public String getCityId() {
		return cityId;
	}

	public void setCityId(String cityId) {
		this.cityId = cityId;
	}

	public String getCityName() {
		return cityName;
	}

	public void setCityName(String cityName) {
		this.cityName = cityName;
	}

	public String getCityCode() {
		return cityCode;
	}

	public void setCityCode(String cityCode) {
		this.cityCode = cityCode;
	}

	public String getProvince() {
		return province;
	}

	public void setProvince(String province) {
		this.province = province;
	}
}
