Hi,

I just played around with the graceful shutdown option server.shutdown.grace-period=1s while being on Tomcat 9.0.31 and got this error.

2020-04-08 20:40:46.278  INFO 42505 --- [extShutdownHook] o.s.b.w.e.tomcat.TomcatGracefulShutdown  : Commencing graceful shutdown, allowing up to 1s for active requests to complete

Should we consider add example to each topics?
How to use it and best practice to use it!

I.e: for helloworld demo the example would be http://localhost:8080/demo/hello?who=ibrahim

有很多开发者朋友问我有没有类似的前台项目、后台管理项目的种子项目，其实都是类似的，区别在于这些项目需要模版引擎(不建议使用JSP)和静态资源(css、js、img)的支持，稍微调整下即可适用，按照MVC的分层来说的话差异的只是视图层，下面是基于Thymleaf模板引擎的改造步骤，供参考。

1. 加入Thymleaf模板引擎依赖

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-thyme

提交 Issues 请提供

1. 提供发生错误的步骤，最好有 GIf 动图
2. 异常日志（尽量详细，异常日志可以使用MD语法）

对于没有提供详细日志的 Issues 将直接关闭。谢谢
