springMVC实例化ThymeleafView失败

Question

这是一个springMVC程序在tomcat上使用Thymeleaf,idea,maven, tomcat可以正常运行，程序能够进入控制器，但是tomcat会返回一个500 web一旦控制器返回Thymeleaf的html文件，似乎springMVC未能实例化ThymeleafView，我不知道为什么会发生，这里是我的springMVC.xml web.xml和错误报告

根据错误报告

，我试图在maven中添加以下依赖项

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>4.0.1</version>
<scope>provided</scope>
</dependency>

和ServletDispather似乎无法部署，因为tomcat错误报告更改为404

Answer 1

感谢m.d inum的评论，这正是问题的原因，我的tomcat版本是10，我的springMVC版本是6，但我使用的是thymleaf -spring5，问题解决后，我把它改成了thymleaf -spring6，我没有考虑之前的版本。
