我收到错误 -
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
org/eclipse/jdt/internal/compiler/env/INameEnvironment
In my case it worked by adding this dependency in pom.xml file.
It is needed to compile jsp don't know why tomcat-embed-jasper version is not working
