Question

我使用Spring 3.2和Hibernate 3.6.7。

我有一个显示实体的表单，表单被提交并保存实体。使用saveOrUpdate方法。

直到我创建了我的实体类implements FieldHandled。现在saveOrUpdate（）什么都不做。

我阅读了Hibernate源代码，它说（快捷方式）如果实体实现了FieldHandled，并且FieldHandler没有脏，那么什么都不做。

这是我的代码：

@Controller
@Transactional
public class CustomerContactController {

    ....

    @ModelAttribute
    public CustomerContactAddressDTO getCustomerContactAddress(final HttpServletRequest request) {
        CustomerContactAddressDTO customerContactAddressDTO = new CustomerContactAddressDTO();
        customerAddress = customerAddressDao.findById(customerAddressUid);
        customerContactAddressDTO.setCustomerContact(customerAddress.getCustomerContact());
        return customerContactAddressDTO;       
    }

    @Secured(UserService.ROLE_PREFIX + "right.customer.contact.update")
    @RequestMapping(value = "/customer/contact/formedit/{customerContactAddressDTOUid}", method = RequestMethod.POST)
    public @ResponseBody
    ReturnFormResult formEditSubmit(@ModelAttribute CustomerContactAddressDTO customerContactAddressDTO,
            @PathVariable final String customerContactAddressDTOUid) {

        final CustomerAddress customerAddress = customerContactAddressDTO.getCustomerAddress();

        ReturnFormResult rfr = new ReturnFormResult();
        rfr.setMode("update");
        rfr.setStatus(Boolean.TRUE);

        customerAddressDao.saveOrUpdate(customerAddress);

        return rfr;
    }
}

实体：

@Entity
@Table(name = "t_customer_contact_address")
public class CustomerAddress implements FieldHandled{

    @Id
    @GeneratedValue(generator = "uuid")
    @GenericGenerator(name = "uuid", strategy = "uuid2")
    @Column(name = "customer_contact_address_uid", updatable = false)
    private String id;

    ....

    @Basic(fetch=FetchType.LAZY)
    @Formula("(some native sql query)")
    private String groupTransactionCodes;


    private FieldHandler fieldHandler;

    @Override
    public void setFieldHandler(FieldHandler handler) {
        this.fieldHandler = handler;

    }

    @Override
    public FieldHandler getFieldHandler() {     
        return fieldHandler;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {  
        this.id = id;       
    }

    public String getGroupTransactionCodes() {
        if(fieldHandler!=null){
            return (String)fieldHandler.readObject(this, "groupTransactionCodes", groupTransactionCodes);
        }       
        return groupTransactionCodes;
    }

    public void setGroupTransactionCodes(String groupTransactionCodes) {
        this.groupTransactionCodes = groupTransactionCodes;
    }   
}

这是hibernate代码源

!FieldInterceptionHelper.isInstrumented( entity ) = false，因为我的实体已被修改

FieldInterceptionHelper.extractFieldInterceptor( entity)返回我的实体的fieldHandler，这是脏的== false

true＆amp;＆amp; （false || false || false）= false

hibernate源代码：

as mightBeDirty == false对他来说更新不是必要的，也没有安排更新。

我的问题：当我在已经检测的分离实体上使用它时，我怎么能让saveOrUpdate（）在数据库中真正更新？

由于

数据库配置：

我在保存前就这样做了： customerAddress.getFieldHandler().writeObject(customerAddress, "name", customerAddress.getName(), customerAddress.getName());

它会迫使脏到真。我觉得当Entity实现FieldHandled时，它会阻止任何类型的自动运行时检测。我想我应该像这样手工实现所有的setter：

    public void setXXX(String xxx) {
            getFieldHandler().writeObject(this, "xxx", this.xxx, xxx);
            this.xxx = xxx;
    }

在每个setter中手动调用writeObject。

Hibernate SaveOrUpdate什么都不做
