看起来是pom.xml里面存在mybatis和spring框架版本不兼容的问题？建议和课程版本保持一致

  框架版本就是和视频里的版本是一样的，我原本是用2019的idea做的项目，但是那个idea突然问题了，一启动就报could not find main class com/intellij/idea/main错误，启动不了，我百度了很久也解决不了，于是又装了一个2020的idea，重新导入项目，tomcat正常启动页也是有的，但一填入controller层转发地址就会报500错误，怎么办

  这个看起来还是版本不兼容的问题，同学直接复制粘贴最终源码里面的pom.xml试试？ 
  此外，也可以按照这个https://blog.csdn.net/khxu666/article/details/79851070
  搭建起来，先确保能访问到，然后再和视频一样编码也是可以的
