Spring Security - Third Edition

PreAuthenticatedGrantedAuthoritiesUserDetailsService

The PreAuthenticatedGrantedAuthoritiesUserDetailsService interface removed createuserDetails in favor of createUserDetails.

The new method has a correction in the case (U instead of u).

This means that if you have a subclass of the PreAuthenticatedGrantedAuthoritiesUserDetailsService class that overrides the createuserDetails,  SubclassPreAuthenticatedGrantedAuthoritiesUserDetailsService extends PreAuthenticatedGrantedAuthoritiesUserDetailsService.

{      @Override      protected UserDetails createuserDetails(Authentication token,                  Collection<? extends GrantedAuthority> authorities) {            // customize      }}

It should be changed to override createUserDetails:

public class SubclassPreAuthenticatedGrantedAuthoritiesUserDetailsService ...
