【问题描述】:
@Valid 注解在 post 请求到达控制器方法时不会触发验证。我该怎么办?
父控制器:
public class ApplicationController {
@Autowired
private I18NService i18NService;
public I18NService getI18NService() {
return i18NService;
}
public void setI18NService(I18NService i18NService) {
this.i18NService = i18NService;
}
}
布局控制器:
public class ClientLayoutController extends ApplicationController{
@Autowired
private UserService userService;
@Autowired
private ClienteService clienteService;
protected ModelAndView getModelAndView(String aActiveMenu, String aI18n, String aViewName){
ModelAndView mav = new ModelAndView();
User user = userService.getAuthenticatedUser();
Cliente cliente = clienteService.getAuthenticatedCliente();
mav.addObject("active_menu",aActiveMenu);
mav.addObject("titulo",this.getI18NService().getMessage(aI18n));
mav.addObject("user",user);
mav.addObject("cliente",cliente);
mav.setViewName(aViewName);
return mav;
}
// Getters ans Setters...
}
请求进来的Controller:
@Controller
public class ClienteController extends ClientLayoutController {
@GetMapping("/client/profile")
public ModelAndView clientProfile() {
ModelAndView mav = this.getModelAndView("profile","client.profile","store/account-profile");
return mav;
}
@PostMapping("/client/profile")
public ModelAndView clientProfileUpdate(@Valid Cliente cliente,BindingResult bindingResult,Model model) {
System.out.println("sdfsdf "+cliente.getNome());
System.out.println(bindingResult.getErrorCount());
if(bindingResult.hasErrors()){
ModelAndView mav = this.getModelAndView("profile","client.profile","store/account-profile");
mav.addObject("cliente",cliente);
return mav;
}
return this.getModelAndView("profile","client.profile","store/account-profile");
}
}
百里香形式:
<form th:method="post" th:action="@{'/client/profile'}" th:object="${cliente}">
<div class="form-group">
<label for="nomecli" th:text="#{client.profile.name}">First Name</label>
<input th:field="*{nome}" type="text" id="nomecli" class="form-control" th:placeholder="#{client.profile.name}"/>
<span th:if="${#fields.hasErrors('nome')}" th:errors="*{nome}" class="text-danger"></span>
</div>
<button type="submit" class="btn btn-default btn-theme" th:inline="text"><i class="fa fa-check"></i> [[#{crud.save}]]</button>
</form>
实体:
@Entity(name = "cliente")
public class Cliente {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Column(name = "nome")
@NotEmpty(message = "Informe o nome")
private String nome;
// Other fields...
}
bindingResult.getErrorCount() 始终为 0,即使我发布了空白表单。我尝试在 google 上添加 @NotNull 和许多其他内容,但没有成功。
