下面是我的物體類。

@Entity
@Table(name = "`ORDER`")
public class OrderVO implements Serializable{
    private static final long serialVersionUID = 1L;

@Id
@Column(name = "ORDER_ID")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer orderId;

@Column(name = "USER_ID")
private Integer userId;

@Column(name = "ORDER_STATUS", insertable = false)
private Integer orderStatus;

@Column(name = "NOTE")
private String note;

@Column(name = "USER_LOCATION")
private String userLocation;

@Column(name = "ORDER_CREATE", insertable = false)
private Timestamp orderCreate;

@Column(name = "ORDER_DONE", insertable = false)
private Timestamp orderDone;

@Column(name = "PRODUCT_KCAL_TOTAL")
private Integer productKcalTotal;

@Column(name = "TOTAL")
private Integer total;

@Column(name = "DEL_COST")
private Integer delCost;

@Column(name = "USE_CASH")
private Boolean useCash;

@Column(name = "CREDIT_ID")
private String creditId;

@Column(name = "DISCOUNT")
private Integer discount;

@Column(name = "RATING", insertable = false)
private Boolean rating;

@Column(name = "RES_RATE", nullable = true)
private Double resRate;

@Column(name = "DEL_RATE", nullable = true)
private Double delRate;

@Column(name = "RES_COMMENT", nullable = true)
private String resComment;

@Column(name = "DEL_COMMENT", nullable = true)
private String delComment;

@Column(name = "PROMOTE_ID", nullable = true)
private Integer promoteId;

@OneToMany(
        mappedBy = "orderVO",
        cascade = {CascadeType.REMOVE} 
)
private Set<OrderDetailVO> orderDetailVO;

@ManyToOne
@JoinColumn(
        name = "RES_ID",
        referencedColumnName = "RES_ID"
)
private ResVO resVO;

@ManyToOne
@JoinColumn(
        name = "DEL_ID",
        referencedColumnName = "DEL_ID"
)
private DelBean del;

服務：

@Service
@Transactional
public class OrderServiceImpl implements OrderService {
    
    @Autowired
    private OrderDAO dao;
    @Autowired
    private PromoteListDAO promoteListDAO;
    
        
    @Override
    public List<OrderVO> adminFindOrderAll(){
        List<OrderVO> list = dao.getAll();
        return list;
    }

存盤庫：

    @Repository
    public class OrderDAOimpl implements OrderDAO {

    @PersistenceContext
    private Session session;
    
    public Session getSession() {
        return session;
    }


    @Override
    public List<OrderVO> getAll() {
        return (List<OrderVO>) this.getSession().createQuery("FROM OrderVO ORDER BY orderId", 
        OrderVO.class).list();
    }

控制器：

    @RestController
@RequestMapping(path = {"/AdminOrderAllServlet"})
public class AdminOrderAllServlet{
    
    @Autowired
    private OrderService orderService;
    
    @PostMapping
    public Map<String, Object> handlerMethod() {
        Map<String, Object> respObj = new HashMap<String, Object>();
        List<OrderVO> list = orderService.adminFindOrderAll();
        respObj.put("Orders", list);
        return respObj;
    }
    
}

解決方案之一是在 application.properties 中關閉惰性，但它仍然不起作用。

jpa：properties.hibernate：enable_lazy_load_no_trans：真

如果有什么想法請告訴我，謝謝！

uj5u.com熱心網友回復：

你需要使用@JsonManagedReference并@JsonBackReference讓杰克遜更好地處理這種關系。

下面是例子

public class A
{
    ...
    ...
    @JsonManagedReference
    @OneToMany(...)
    public Set<B> b
    ...
    ...
}

public class B
{
    ...
    ...
    ...
    @JsonBackReference
    @ManyToOne(...)
    @JoinColumn(...)
    public A a
    ...
    ...
}
