The documentation says User findFirstByOrderByLastnameAsc();.

My code:

@Repository
public interface UserRepo extends JpaRepository<Users, Integer>{
    // Users findByUsername(String username); // builds
    Users findFirstOrderByUsername(String username); // builds
    //Users findFirstByOrderByUsername(String username); // fails to build
    //Users findFirstByOrderByUsernameAsc(String username); // fails to build
...
}


@Service
public class UserDetailsServices implements UserDetailsService{

    @Autowired
    private UserRepo repo;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {

        Users userA = repo.findFirstOrderByUsername(username); // builds
        //Users userB = repo.findFirstByOrderByUsername(username); // fails to build
        //Users userC = repo.findFirstByOrderByUsernameAsc(username); // fails to build
    //...
}

The error for findFirstByOrderByUsername is:

...Could not create query for public abstract ....model.Users ....repo.UserRepo.findFirstByOrderByUsername(java.lang.String); Reason: Failed to create query for method public abstract ....model.Users ....repo.UserRepo.findFirstByOrderByUsername(java.lang.String); At least 1 parameter(s) provided but only 0 parameter(s) present in query...

The error for findFirstByOrderByUsernameAsc is:

...Could not create query for public abstract ....model.Users ....repo.UserRepo.findFirstByOrderByUsernameAsc(java.lang.String); Reason: Failed to create query for method public abstract ....model.Users ....repo.UserRepo.findFirstByOrderByUsernameAsc(java.lang.String); At least 1 parameter(s) provided but only 0 parameter(s) present in query...

Using findFirstByOrderByUsernameAsc causes the build failure. Can I consider this possibly a bug in Spring Boot or JPA or documentation? Can I consider this a bug in my code?

The documentation says User findFirstByOrderByLastnameAsc();.
