JPA Repository findAll returns empty list

Question

I am trying to fetch a list from database and findAll() returns empty list. I have multiple jpa repositories but only one does not work. This is the code:

@Repository
public interface ProductCategoryRepository extends JpaRepository<ProductCategory,Integer> {
}

and this is the entity:

@Entity
@Data
@NoArgsConstructor
@AllArgsConstructor
public class ProductCategory {
    @Id
    private Integer id;
    private String name;
    private String description;

    @OneToMany(fetch = FetchType.EAGER,mappedBy = "productCategory", cascade = CascadeType.ALL)
    @JsonIgnore
    private List<Product> products = new ArrayList<>();
}

When I call productCategoryRepository.findAll() it returns empty list thus I have many entries in the database. Thanks for your help!

Answer 1

我遇到了同样的问题，我解决了生成 getter 和 setter 的问题，因为我没有配置我的 lombok

Answer 2

Can you please add @Column annotation to fields (except id) and try ? HOpe it will work.Do let me know if you still do not result.
