Hibernate SaveOrUpdate doing nothing

Question

I work with Spring 3.2 and Hibernate 3.6.7.

I have a form that display an entity, the form is submited and the entity is saved. Using the saveOrUpdate method.

It worked until I made my entity class implements FieldHandled. Now saveOrUpdate() does nothing.

I read the Hibernate source code and it says (shortcut) that if the Entity implements FieldHandled and if the FieldHandler is not dirty then does nothing.

here is my code :

@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;
    }
}

Entity :

@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;
    }   
}

this is hibernate code source

!FieldInterceptionHelper.isInstrumented( entity ) = false because my entity is intrumented

FieldInterceptionHelper.extractFieldInterceptor( entity) return the fieldHandler of my Entity which is dirty == false

true && ( false || false || false) = false

hibernate source code :

as mightBeDirty == false for him update is notNecessary and doesn't schedule update.

My question : How could I have make the saveOrUpdate() really update in database when I use it on detached entity wich are instrumented ?

Thanks

Answer 1

I hacked by just doing this before saving : customerAddress.getFieldHandler().writeObject(customerAddress, "name", customerAddress.getName(), customerAddress.getName());

it will force dirty to becode true. I feel like when a Entity implements FieldHandled, It prevent any kind of automatic runtime instrumentation.I think I should implement all the setter by hand like this :

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

calling writeObject by hand in each setter.
