SpringBoot结合Thymeleaf模板与Bootstrap快速搭建界面

前言

本系列文章将简单的学习SpringCloud微服务相关知识,其实也是因为时间的原因,一直拖到现在,遂打算趁着假期,决定记录下来。

从天气预报微服务系统的单体架构——>分布式架构的演变过程中,一步一步,由浅及深的学习SpringCloud微服务的思想与其实现的组件。

本系列文章分为以下几个章节:

项目源码已上传至Github.

开发环境

  • JDK 1.8
  • IDEA 2017.3
  • Gradle 4
  • HttpClient 4.5.3
  • SpringBoot 2.0.0.RELEASE
    //该依赖用于编译阶段
    compile('org.springframework.boot:spring-boot-starter-web')
    //热部署
    compile('org.springframework.boot:spring-boot-devtools')
    //HttpClient
    compile('org.apache.httpcomponents:httpclient:4.5.3')
    //Redis
    compile('org.springframework.boot:spring-boot-starter-data-redis')
    //Quartz
    compile('org.springframework.boot:spring-boot-starter-quartz')
    //Spring Boot Thymeleaf Starter
    compile('org.springframework.boot:spring-boot-starter-thymeleaf')

开发过程

为了给项目一个“面子”,我们选择与SpringBoot集成的标签模板Thymeleaf和前端框架Bootstrap。

Thymeleaf的使用呢,其实和以前我们学过的EL表达式十分相似。通过对后台的值进行解析并绑定到相对的标签上。

后台请求控制器

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

    @Autowired
    private CityDataService cityDataService;
    @Autowired
    private WeatherReportService weatherReportService;

    @GetMapping("/cityId/{cityId}")
    public ModelAndView getReportByCityId(@PathVariable("cityId") String cityId, Model model) throws Exception{
        model.addAttribute("title","飞翔的天气预报");
        model.addAttribute("cityId",cityId);
        model.addAttribute("cityList",cityDataService.listCity());
        model.addAttribute("report",weatherReportService.getDataByCityId(cityId));

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


}

通过天气预报API查询到的数据,存储到model视图中,返回给前端。前端如何解析呢?

report.js

实现下拉框的效果

//report页面下拉框事件
$(function () {
    $("#selectCityId").change(function () {
        var cityId = $("#selectCityId").val();
        var url = "/report/cityId/" + cityId;
        window.location.href = url;
    })
});

效果展示

浏览器访问http://localhost:8080/report/cityId/101280800
