创建基于Thymeleaf模板引擎的Spring Boot Web应用

1．创建基于Thymeleaf模板引擎的Spring Boot Web应用ch5_2
2．设置Web应用ch5_2的上下文路径
3．创建实体类Book
4．创建控制器类ThymeleafController
5．整理脚本样式静态文件
6．View视图页面
7．运行
整理脚本样式静态文件

JS脚本、CSS样式、图片等静态文件默认放置在src/main/resources/static目录下，ch5_2应用引入了BootStrap和jQuery
View视图页面

Tymeleaf模板默认将视图页面放在src/main/resources/templates目录下。因此，我们在src/main/resources/templates目录下新建html页面文件index.html。在该页面中，使用Tymeleaf模板显示控制器类TestThymeleafController中的model对象数据。
