модель:

@Entity
@Table(name = "usr") // PostgreSQL not work with table "user"
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;
    @NotNull
    private String username;
    @NotNull
    private String password;
    @NotNull
    private boolean active;
    @NotNull
    @ElementCollection(targetClass = Role.class, fetch = FetchType.EAGER)
    @Column(name = "role", nullable = false)
    @CollectionTable(name = "user_roles", joinColumns = @JoinColumn(name = "user_id"))
    @Enumerated(EnumType.STRING)
    private Set<Role> roles;
    @NotNull
    @DateTimeFormat(pattern = "dd.MM.yyyy HH:mm:ss")
    private Date created;
    @DateTimeFormat(pattern = "dd.MM.yyyy HH:mm:ss")
    private Date updated;
    @OneToMany(mappedBy = "user", fetch = FetchType.EAGER,
            cascade = CascadeType.ALL)
    private Set<Orders> orders;

@Entity
public class Category {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;
    @NotNull
    private String name;
    private String description;
    @NotNull
    @DateTimeFormat(pattern = "dd.MM.yyyy HH:mm:ss")
    private Date created;
    @DateTimeFormat(pattern = "dd.MM.yyyy HH:mm:ss")
    private Date updated;
    @OneToOne(fetch = FetchType.EAGER,
            cascade = CascadeType.ALL,
            mappedBy = "category")
    private Orders orders;

@Entity
public class Orders {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;
    @NotNull
    private String name;
    private String description;
    @NotNull
    @DateTimeFormat(pattern = "dd.MM.yyyy HH:mm:ss")
    private Date created;
    @DateTimeFormat(pattern = "dd.MM.yyyy HH:mm:ss")
    private Date updated;
    @OneToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "category_id")
    private Category category;
    @ManyToOne(fetch = FetchType.EAGER, optional = false)
    @JoinColumn(name = "user_id", nullable = false)
    private User user;

здесь мой заказ репо:

public interface OrderRepository extends CrudRepository<Orders, Integer> {

    // Spring Data - use JPQL -> generate SQL query on runtime
    public List<Orders> findByName(String name);

    public List<Orders> findByNameOrderById(String name);

    public List<Orders> findByUser(User user);

}

здесь контроллер:

@org.springframework.stereotype.Controller
public class OrdersController {
    @Value("${spring.application.name}")
    private String appName;
    @Autowired
    private UserRepository userRepository;
    @Autowired
    private OrderRepository orderRepository;
    @Autowired
    private CategoryRepository categoryRepository;
    private User currentUser;

    private static Logger logger = LogManager.getLogger(OrdersController.class);

    @GetMapping("/orders")
    public String getAllOrders(Model model) {
        currentUser = userRepository.findByUsername(UserService.getCurrentUserName());
        List<Orders> orders = orderRepository.findByUser(currentUser);
        model.addAttribute("ordersList", orders);
        model.addAttribute("appName", appName);
        return "orders";
    }

    @RequestMapping("order/add")
    public String addOrder(Model model) {
        logger.info("addOrder,categoriesList = " + categoryRepository.findAll());
        model.addAttribute("isAdd", true);
        model.addAttribute("order", new Orders());
        model.addAttribute("title", "Add Order");
        model.addAttribute("viewMode", ViewMode.ADD);
        model.addAttribute("categoriesList", categoryRepository.findAll());
        return "order";
    }  

    @RequestMapping("order/delete/{id}")
    public String deleteOrder(@PathVariable("id") int orderId) {
        orderRepository.deleteById(orderId);
        logger.info("success_delete_orderId = " + orderId);
        //notifyByEmail(NotifyActionEnum.ORDER_DELETE, orderId);
        return "redirect:/orders";
    }

Я могу Успешное добавление и редактирование заказа. По удалению не работает. Метод успешного вызова deleteOrder, успешный вывод:

success_delete_orderId

, но порядок не удаляется из базы данных db

здесь: db log:

Answer 1

Удаляется, если id существует.

DEBUG 11348 --- [main] org.hibernate.SQL: delete from orders where id=?

Если id не существует EmptyResultDataAccessException выбрасывается:

org.springframework.dao.EmptyResultDataAccessException: No class com.package.Orders entity with id XX exists!
