Spring MVC view & update

Question

Я пытаюсь обновить данные из представления Spring MVC. Я мог обновлять данные, используя объект тестера, но не смог выполнить попытку обновления из представления Spring MVC. Запрос POST из представления не имеет проблемных ключей/значений, отправляемых на сервер. Он обновил мои данные таблицы, но с нулевым значением (если только для поля id).

Просьба помочь и поблагодарить вас.

Моя таблица (tx_surveyrequest)

CREATE TABLE tx_surveyrequest 
(
id uuid NOT NULL, 
id_person uuid, 
id_surveyrequeststatus uuid, 
id_validationstatus uuid, 
id_employee_assistantgis uuid, 
formcode character varying(64), 
b_north character varying(32), 
b_east character varying(32), 
b_south character varying(32), 
b_west character varying(32), 
hectarage numeric(10,2), 
is_priority boolean DEFAULT false, 
requestdate date, 
surveyplandate date, 
surveyplantime time without time zone, 
requestedby character varying(32), 
requestedprice numeric(14,2), 
CONSTRAINT pk_tx_surveyrequest PRIMARY KEY (id) 
) 

Мой домен объект (SurveyRequest)

@Entity

private String borderWest; 
private Double hectarage; 
private Boolean priority; 
private DateTime requestDate; 
private DateTime surveyPlanDate; 
private LocalTime surveyPlanTime; 
private String requestedBy; 
private Double requestedPrice; 

@Id 
@GeneratedValue(strategy = IDENTITY) 
@Column(name = "id") 
@Type(type="pg-uuid") 
public UUID getId() { 
    return id;

public void setId(UUID id) { 
    this.id = id;

public void setFormCode(String formCode) { 
    this.formCode = formCode; 
} 

@Column(name="is_priority") 
public Boolean getPriority() { 
    return priority; 
} 

public void setPriority(Boolean priority) { 
    this.priority = priority; 
} 

@Column(name="b_north")

успех Обновление с помощью SurveyRequestUpdate

public class SurveyRequestUpdate { 

public static void main(String[] args) { 
    GenericXmlApplicationContext ctx = new GenericXmlApplicationContext(); 
    ctx.load("classpath:spring-data-app-context.xml"); 
    ctx.load("classpath:datasource.xml"); 
    ctx.refresh(); 

    SurveyRequestService surveyRequestService = ctx.getBean(
      "springJpaSurveyRequestService",SurveyRequestService.class); 

    UUID uid = UUID.fromString("0cd02976-1864-447b-b540-39d6e7ee3703");  
    SurveyRequest request = surveyRequestService.findById(uid); 
    System.out.println("Find by ID"); 
    System.out.println(request);   
    request.setSurveyPlanDate (new DateTime(2014,7,1,0,0)); 
    request.setSurveyPlanTime (new LocalTime(22,0)); 
    surveyRequestService.save(request); 
    System.out.println(request); 
}

Мой контроллер

@RequestMapping("/surveyrequest") 
@Controller 
public class SurveyRequestController { 
private static final int PAGE_SIZE = 10; 

private static final Logger logger = LoggerFactory 
     .getLogger(SurveyRequestController.class); 

@Autowired 
MessageSource messageSource; 

@Autowired 
private SurveyRequestService surveyRequestService; 

// Others code omitted 

@RequestMapping(value="/{id}", method = RequestMethod.GET) 
public String show(@PathVariable("id") UUID id, Model model) { 
    SurveyRequest request = surveyRequestService.findById(id); 
    model.addAttribute("surveyRequest", request); 
    return "surveyrequest/show"; 
} 

/* 
* Edit a survey request 
*/ 
@RequestMapping(value="/{id}", params="form", method = RequestMethod.GET) 
public String updateForm(@PathVariable("id") UUID id, Model model) { 
    SurveyRequest request = surveyRequestService.findById(id); 
    model.addAttribute("surveyRequest", request); 
    return "surveyrequest/edit"; 
} 
/* 
* Update a survey request 
*/ 
@RequestMapping(value = "/{id}", params = "form", method = RequestMethod.POST) 
public String update(SurveyRequest surveyRequest, BindingResult bindingResult, Model uiModel, 
     HttpServletRequest httpServletRequest, RedirectAttributes redirectAttributes, Locale locale) { 

    if (bindingResult.hasErrors()) { 
     uiModel.addAttribute("message", new Message("error", messageSource.getMessage("surveyrequest_save_fail", new Object[]{}, locale)));   
     uiModel.addAttribute("surveyRequest", surveyRequest); 
     return "surveyrequest/update"; 
    } 
    uiModel.asMap().clear(); 
    redirectAttributes.addFlashAttribute("message", new Message("success", messageSource.getMessage("surveyrequest_save_success", new Object[]{}, locale)));   
    logger.info("Before paste: " + surveyRequest); 
    surveyRequestService.save(surveyRequest); 

    return "redirect:/surveyrequest/" + UrlUtil.encodeUrlPathSegment(surveyRequest.getId().toString(), httpServletRequest); 
} 

Обновлено: Я мог бы решить проблему с удалением ENCTYPE = "многослойную/форм-данных" в edit.jspx. Но это подняло еще одну проблему, как, если я собираюсь загрузить файл?

Answer 1

Добавить @ModelAttribute аннотацию к параметру объекта модели в методе контроллера, который вы вызываете, так что Spring знает, что это объект, к которому вы хотите привязать данные формы.

/* 
* Update a survey request 
*/ 
@RequestMapping(value = "/{id}", params = "form", method = RequestMethod.POST) 
public String update(@ModelAttribute("surveyRequest") SurveyRequest surveyRequest, 
        BindingResult bindingResult, Model uiModel, 
        HttpServletRequest httpServletRequest, 
        RedirectAttributes redirectAttributes, Locale locale) { 
    [...] 
}
