UserRepository
@Repository
public interface UserRepository extends JpaRepository<User, Long> {
Optional<User> findByUsername(String userName);
}
UserDtailsServiceImpl
@Service public class UserDetailsServiceImpl implements UserDetailsService {
private UserRepository userRepository;
public UserDetailsServiceImpl(UserRepository userRepository) {
this.userRepository = userRepository;
}
@Override
public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
// todo throw if not exist
return userRepository.findByUsername(s).get();
}
}
pvpkiran :
The method name should be findByUserName in the repository and not findByUsername
@Repository
public interface UserRepository extends JpaRepository<User, Long> {
Optional<User> findByUserName(String userName);
}
