從屬對象上的彈簧窗體驗證

我在驗證我的表單時遇到了這個問題，對於單個實體，它工作正常。但是當我嘗試使用嵌套對象驗證對象時，出現此錯誤。從屬對象上的彈簧窗體驗證

HTTP Status 500 - Request processing failed; nested exception is javax.validation.ConstraintViolationException: Validation failed for classes [com.poultry.jp.model.PaymentRequest] during persist time for groups [javax.validation.groups.Default, ]

以下是我的控制器

@RequestMapping(value = {"user/addMedicineOrder","admin/addMedicineOrder"}, method = RequestMethod.GET) 
public String addMedicineOrderGET(@ModelAttribute("medicineOrder") MedicineOrder medicineOrder,Model model) { 

    List<SupplierReport> supplierReport = supplierService.getSupplierNames(); 
    List<MedicineOrderReport> medicineOrderReport = medicineOrderService.getMedicineOrderDetails(); 
    List<PaymentRequestReport> paymentRequestReport = paymentRequestSerivice.getPaymentRequestDates(); 
    List<MedicineReport> medicineReport = medicineService.getMedicineDetails(); 

    model.addAttribute("medicineOrderReport",medicineOrderReport); 
    model.addAttribute("supplierReport", supplierReport); 
    model.addAttribute("paymentRequestReport", paymentRequestReport); 
    model.addAttribute("medicineReport", medicineReport); 

    return "addMedicineOrder"; 
} 

@RequestMapping(value = {"user/addMedicineOrder","admin/addMedicineOrder"}, method = RequestMethod.POST) 
public String addMedicineOrderPOST(@Valid @ModelAttribute("medicineOrder") MedicineOrder medicineOrder,BindingResult result) { 


    if (result.hasErrors()) { 
     return "addMedicineOrder"; 
    } else { 

     medicineOrderService.save(medicineOrder); 


     return "redirect:addMedicineOrder.html"; 
    } 
}

以下是我的醫藥訂貨型號

public class MedicineOrder { 

@Id 
@GeneratedValue(strategy = GenerationType.AUTO) 
private Long medicineOrderId; 

@OneToMany(mappedBy = "medicineOrder", cascade = CascadeType.ALL,fetch = FetchType.EAGER,orphanRemoval=true) 
private List<MedicineOrderDetails> medicineOrderDetails = new ArrayList<MedicineOrderDetails>(); 

@ManyToOne 
private Supplier supplier; 

@DateTimeFormat(pattern = "yyyy-MM-dd") 
@Temporal(TemporalType.DATE) 
private Date date; 

private double total; 

private double discount; 
private boolean inStock; 

@OneToOne(cascade={CascadeType.MERGE , CascadeType.PERSIST}) 
@JoinColumn(name="paymentRequest_id") 
private PaymentRequest paymentRequest; 

private boolean isDeleted; 
private Date created; 
private Date updated; 
// Getters and Setters 
}

以下是依賴類付款申請公共類PaymentRequest {

public static final String FIND_PAYMENT_REQUEST_DATES = "findPaymentReequestDates"; 
public static final String FIND_PAYMENT_REQUEST_BY_ID = "findPaymentReequestById"; 
public static final String FIND_PAYMENT_REQUEST_REPORT = "findPaymentRequestReport"; 


@Id 
@GeneratedValue(strategy = GenerationType.AUTO) 
private Long paymentId; 
private double amount; 
@Type(type = "text") 
@NotEmpty 
private String description; 
private String chequeID; 
private String status; 

@DateTimeFormat(pattern = "yyyy-MM-dd") 
@Temporal(TemporalType.DATE) 
private Date date; 

private boolean isDeleted; 
private boolean isPaid; 

private Date created; 
private Date updated; 
//Getters and Setters 
}

和以下是我堅持醫藥秩序堅持支付請求與它。

@Repository("MedicineOrderRepository")

公共類MedicineOrderRepositoryImp實現MedicineOrderRepository {

@PersistenceContext 
private EntityManager entityManager; 

public MedicineOrder save(MedicineOrder medicineOrder){ 

    for(MedicineOrderDetails order : medicineOrder.getMedicineOrderDetails()) 
    { 
     order.setMedicineOrder(medicineOrder); 
    } 

    medicineOrder.getPaymentRequest().setStatus("Pending"); 
    entityManager.persist(medicineOrder); 
    entityManager.flush(); 

    return medicineOrder; 
} 
}

終於以下JSP代碼。

<div class=".col-md-6"> 
     <form:form commandName="medicineOrder" class="form-horizontal" 
      autocomplete="off"> 
      <form:errors path="*" Class="alert alert-danger" element="div" />

       </div> 
      </div> 

      <div class="form-group">

      </div> 

      <div class="form-group">

       <div class="col-sm-5">

          itemValue="supplierId" id="" /> 
        </form:select> 
       </div> 
      </div> 
      <div class="form-group">

       <div class="col-sm-5"> 
        <form:input path="total" type="text" class="form-control"

       </div> 
      </div> 
      <div class="form-group"> 
       <label for="inputDiscount" class="col-sm-2 control-label">Discount

         id="inputDiscount" /> 
       </div> 
      </div> 

      <input type="submit" value="Save Medicine Order" 
       class="btn btn-primary"> 

     </form:form> 
    </div>
