spring - 保存功能上的 EntityNotFoundException

Question

我正在尝试使用一对多关系保存实体。EntityNotFoundException尝试保存实体时抛出

我做了一些研究，但找不到任何解决方案

订单实体：

@Data
@Component
@Entity
@Slf4j
@Table (name = ORDER_TABLE_NAME)
public class OrderEntity {

//== Order Details
    @Id
    @GeneratedValue(generator = "uuid")
    @GenericGenerator(name = "uuid", strategy = "uuid2")
    @Column(name = ORDER_ID_COLUMN)
    private String orderIdGuid;

    @Column (name = ORDER_BOOKED_DATETIME_COLUMN)
    private LocalDateTime orderBookedDate;

    @Column(name = ORDER_STATUS_COLUMN)
    private String orderStatus;

    @OneToMany( cascade={CascadeType.ALL}, orphanRemoval = true)
    @JoinColumn(name= ORDER_ID_COLUMN)
    @Autowired
    private List<ProductEntity> products;

    @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    @JoinColumn(name = ORDER_ID_COLUMN)
    private List<Followup> followups;

产品实体：

@Data
@Component
@Entity
@Table (name=ORDER_PRODUCT_TABLE)
public class ProductEntity {

    @Id
    @GeneratedValue(generator = "uuid")
    @GenericGenerator(name = "uuid", strategy = "uuid2")
    @Column (name = PRODUCT_PRIMARY_ID)
    private String product_primary_id;

    //=== defined by constants
    @Column(name = PRODUCT_NAME)
    private String productName;

DAO类：

@Component
@Data
@Slf4j
public class DAOOrderRepository {

    @Autowired
    OrderRepository orderRepository;

    public void saveOrderEntity(OrderEntity orderEntity) {
        orderEntity.setOrderUpdatedDate(LocalDate.now());
        orderRepository.save(orderEntity);
    }

    public OrderEntity findOrderByOrderId(String orderId) {
        return orderRepository.findOrderEntityByOrderIdGuid(orderId);
    }

    public List<OrderEntity> findAllOrdersByEmployeeId(String employeeId) {
        return orderRepository.findBySalesRepEmployeeId(employeeId);
    }
}

存储库：

@Repository
public interface OrderRepository extends JpaRepository<OrderEntity,String> {

    List<OrderEntity> findBySalesRepEmployeeId(String employeeId);

    OrderEntity findOrderEntityByOrderIdGuid(String orderIdGuid);
}

例外：

at com.sun.proxy.$Proxy111.save(Unknown Source)
at com.app.apicore.Apis.DAOOrderRepository.saveOrderEntity(DAOOrderRepository.java:24)

每个订单都是一个新的订单记录。因此，当我第一次尝试保存订单记录时，它会正确保存订单数据。它第二次正确保存订单数据。但是第三次​​抛出异常。
