Thymeleaf doesn't print list of objects (Spring JPA)

Question

I have 5 different object of class Tour with some fields.I want that my main page shows this object with their fields. I wrote conrtoller:

        @Controller
        public class MainController {
            @Autowired
            private TourRepository tourRepository;
        
            @GetMapping("/")
            public String mainPage(Model model) {    
               
            List<Tour> tourList=tourRepository.findAll();    
            model.addAttribute("tours",tourList);
        
            return "home/main";
            }    

            @RequestMapping("/main")
            public String main() {
       
            return "redirect:/";}
    }

And Repository

public interface TourRepository extends JpaRepository<Tour,Integer> {  
}

application.properties:

# hibernate configurations
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update


# thumeleaf configurations
spring.thymeleaf.mode= HTML
spring.thymeleaf.cache=false

Now I'm trying to pass variable values to the page with Thymeleaf,

<div>

    <table>
        <thead>
            <tr>
                <th>Title</th>
                <th>Price</th>
            </tr>
        </thead>
        <tbody>
            <tr th:each ="tour : ${tours}">
                <td th:utext="${tour.title}">...</td>
                <td th:utext="${tour.price}">...</td>
            </tr>
        </tbody>
    </table>
</div>

but I get five identical duplicates of first record in db. How can I change controller\view?

Answer 1

My primary key named "code" in entity tout in db. Annotation @Id didn't a column with a different name as a primary key. I explicitly added:

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "code")
private int id;
