照例附上项目github链接
本项目实现的是将一个简单的天气预报系统一步一步改造成一个SpringCloud微服务系统的过程，本节主要讲的是通过引入thymeleaf模块构建项目的UI界面。
添加依赖
在pom文件中添加thymeleaf的依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>天气预报服务
提供查询天气的接口
定义一个天气预报服务的接口，提供根据根据城市Id查询信息的功能。
@Service
public class WeatherReportServiceImpl implements WeatherReportService{
@Autowired
private WeatherDataService weatherDataService;
@Override
public Weather getDataByCityId(String cityId) {
WeatherResponse resp=weatherDataService.getDataByCityId(cityId);
return resp.getData();
}
}界面的完善
界面模板内容如下：

</html>js文件内容如下：
/**
* report页面下拉框事件

*/
$(function(){
$("#selectCityId").change(function(){
var cityId = $("#selectCityId").val();
var url = '/report/cityId?cityId='+ cityId;
window.location.href = url;
})
});在Controller层中使用SpringMVC里面的模型以及视图的概念。
需要将城市列表传入模型中，作为下拉框的选择信息提供给用户。
@RestController
@RequestMapping("/report")
public class WeatherReportController {
//返回天气列表使用的
@Autowired
private CityDataService cityDataService;
//返回天气信息使用的
@Autowired
private WeatherReportService weatherReportService;
@GetMapping("/cityId")
public ModelAndView getReportByCityId(String cityId,Model model)throws Exception{
model.addAttribute("title","猪猪天气预报");
model.addAttribute("cityId",cityId);
//返回listget前端，供用户选择
model.addAttribute("cityList",cityDataService.listCity());
model.addAttribute("report",weatherReportService.getDataByCityId(cityId));
return new ModelAndView("weather/report", "reportModel", model);
}
}增加配置：
