Use JpaRepository or CrudRepository as repository interface:

@Repository
public interface CustomerRepository extends JpaRepository {

    @Query("SELECT t from Customer t where LOWER(t.name) LIKE %:name%")
    public List findByName(@Param("name") String name);

}


@Service(value="customerService")
public class CustomerServiceImpl implements CustomerService {

    private CustomerRepository customerRepository;
    
    //...

    @Override
    public List pattern(String text) throws Exception {
        return customerRepository.findByName(text.toLowerCase());
    }
}
