The error relates to your view resolver configuration that is causing a loop in dispatching requests. Without seeing the complete configuration of your Spring Boot application and the context in which this controller is being used, it's a bit challenging to find the exact cause of the issue.

a Few things you can check -
1) Make sure that your view resolver configuration is correctly set up. You should have a 'ViewResolver' bean configured to resolve views to their respective templates. Make sure that your 'ViewResolver' is not causing a loop in resolving the view for the 'dmno' endpoint.
2) Your '@GetMapping(value = "dmno")' annotation specifies that requests to the 'dmno' URL should be handled by the homepage method. It is not clear what you intend to achieve with this method. If you are trying to return a view named 'dmno', you should make sure that the view resolver can properly resolve this view.
3) If you are trying to return a view named 'dmno', ensure that you have a corresponding view template (example 'dmno.html' for Thymeleaf) in your appropriate folder of your project's resources.
