理论

后端通过@GetMapping获取数据，把数据存储在Model中，前端使用模板引擎机进行获取即可。

在@GetMapping中填写请求信息；

Model再通过addAttribute与前端进行交互！

程序运行截图如下：

项目结构如下：

源码如下：

            @Override
            public void addViewControllers(ViewControllerRegistry registry) {

                registry.addViewController("/").setViewName("index");
                registry.addViewController("/index.html").setViewName("index");
