如何忽略Spring JPA findBy仓库中的重音？

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.stereotype.Repository;

@Repository
public interface UserRepository extends JpaRepository<User, Long> {

    @Query("select u from User u where lower(translate(u.name, 'áàäâãåā', 'aaaaaa')) = lower(translate(?1, 'áàäâãåā', 'aaaaaa'))")
    User findByUsernameIgnoringDiacritic(String username);
}
