Why am I not granted permissions when using ".requestMatchers("/").hasAnyAuthority("admin", "staff").anyRequest().authenticated()"?

edit

There could be several reasons why you are not granted permissions when using ".requestMatchers("/").hasAnyAuthority("admin", "staff").anyRequest().authenticated()":

1. You may not have the "admin" or "staff" authority. Make sure that your user account has been assigned one of these authorities.

2. Your authentication provider may not be correctly configured to provide the necessary authorities. Check your authentication configuration to make sure that your provider is configured to authenticate users and provide authorities.

3. Your request may not be mapped correctly to the URL pattern ("/"). Make sure that your request is correctly mapped to this URL pattern.

4. There may be a problem with your authorization configuration. Check your authorization configuration to make sure that your rules are correctly configured and applied in the correct order.

It is also possible that there are other issues that are causing the problem. If you cannot resolve the issue on your own, you may need to seek additional help from a developer or technical support.
