Spring验证器从未调用过

Question

我试图验证一些信息,所以我添加了一个验证器并在post方法的参数中使用了@Valid:

@Controller
@RequestMapping("/user.htm")
public class UserController {

    @Autowired
    private IUserService userService;

    @RequestMapping(method = RequestMethod.GET)
    public String userInfo(Model model) {
       ....
        return "user";
    }

    @RequestMapping(method = RequestMethod.POST)
    public String userInfoResult(@Valid @ModelAttribute UserForm userForm, BindingResult result, Model model ) {

        UserInfo stat = userService.getStatitisque(userForm.getSearchCritera());
        userForm.setListeExpediteur(listeExpediteur);

        userForm.setUserInfo(stat);
        model.addAttribute("userForm", userForm);
    }    
}

public class UserFormValidator implements Validator {

    @Override
    public boolean supports(Class<?> type) {
        return UserForm.class.equals(type);
    }

    @Override
    public void validate(Object o, Errors errors) {
        UserForm userForm = (User) o;
        ...
    }
}

当我调试时,我从未进入UserFormValidator类.

我需要在这些文件中添加内容吗？

• web.xml
• applicationContext.xml
• dispatcher-servlet.xml

Answer 1

您需要在@InitBinder方法中添加验证器:

@InitBinder(value="YourFormObjectName")
protected void initBinder(WebDataBinder binder) {
    binder.setValidator(new FooValidator());
}

或通过XML全局:

<mvc:annotation-driven validator="globalValidator"/>
