首先展示一下这个Error 描述， 大致意思是没有找到我所配置的template的位置，然而我找了N遍
ERROR 20044 --- [nio-8080-exec-7] 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 "demo", template might not exist or might not be accessible by any of the configured Template Resolvers] with root cause
后面重现创建一个工程项目对比发现，thtmeleaf的配置中有一个坑，这里记录下
spring:
thymeleaf: prefix: /templates/
suffix: .html
然而出现了
Fail
注释后
succeed
来一张图片压压惊
好了，祝各位晚安
