IDEA直接编译运行没有报错，但是当打成jar包后运行报：
ERROR 6081 --- [nio-8187-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.thymeleaf.exceptions.TemplateInputException: Error resolving template [/html/home], template might not exist or might not be accessible by any of the configured Template Resolvers] with root cause
需要将return "/html/home";改为 return "html/home"; 将/去掉即可。
