reason

This error is definitely not a configuration error. Later, I suddenly remembered /WEB-INF/viewsthat DeptI modified the directory name after creating a subdirectory dept, but because it has been run through IntelliJ Ideathe configuration in the tomcatprevious, it still exists in the project target/demo/WEB-INF/viewsdirectory Dept, and finally caused the above error. Finally delete that directory, recreate the deptdirectory and run the project .
