I want to resolve the error in Request method 'GET' not supported

I would like to resolve the following errors:

There was an unexpected error (type=Method Not Allowed, status=405).
Request method 'GET' not supported
org.springframework.web.HttpRequestMethodNotSupportedException—Request method 'GET' not supported

When you log in on the login screen and click on the text box on the search screen, the browser hardens and the error above appears.

The environment is Mac, Eclipse 2020, MySQL

Thank you for your cooperation.

Isn't it because the DOCTYPE on the search screen is far away?
I can't find anything strange about the other processing.
