Я пытаюсь записать данные выборки из моей базы данных mysql в форме. Для этого я создал интерфейс, который расширяет репозиторий Jpa. Интерфейс:

 package org.springboot.dao;

import java.util.List;

import org.springboot.entities.Contact;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;

public interface ContactRepo extends JpaRepository<Contact, Integer>{
    
    @Query("from Contact as c where c.user.id=: userId")
    public List<Contact> findContactsByUser(@Param("userId")int userId);

}
 

Мой Метод Контроллера:

     @GetMapping("/show-contacts")
    public String viewContacts(Model model, Principal principal) {
        model.addAttribute("title", "View Contacts");

        
          String userName=principal.getName(); 
          User user=this.repo.getUserByUsername(userName);
          
          List<Contact> contacts=this.crepo.findContactsByUser(user.getId());
          
          model.addAttribute("contacts", contacts);
         
        return "user-view-contacts";
    }

Я пытаюсь показать эти контакты на своей странице просмотра. Когда я запускаю свое приложение, если я комментирую код своего метода контроллера, он показывает представление. Но если я не прокомментирую это, это даст мне эту ошибку. Пожалуйста, попробуйте решить эту ошибку.
Заранее спасибо!
