刚开始毫无头绪，找了很多解决方案，这个错误还是解决不了，后来知道了在pom.xml文件里的的错误了，版本配错了，我Thymeleaf用的是3.0.9.RELEASE的版本 支持程序用的是2.2.2的版本。但是也报错。
<thymeleaf.version>3.0.9.RELEASE</thymeleaf.version>
<thymeleaf-layout-dialect.version>2.2.2</thymeleaf-layout-dialect.version>
解决方案：
<thymeleaf.version>3.0.11.RELEASE</thymeleaf.version>
直接运行成功
附我的idea版本是2019版本的
