我试图用基于 Spring MVC 的 Javax 来创建简单的验证。 我启用了批注驱动程序 。 我想在表格中显示错误, 但有500页错误 :

< 加强> 500 错误页面

@RequestMapping(value="/register", method=RequestMethod.POST)
    public String register(
            @Valid Profile profile,
            @RequestParam("recaptcha_challenge_field") String challenge,
            @RequestParam("recaptcha_response_field") String response, 
            BindingResult result, Model model, HttpServletRequest request) {

        ReCaptchaResponse cResponse = captcha.checkAnswer(request.getRemoteAddr(), challenge, response);
        if(result.hasErrors() || !cResponse.isValid()) {
            String message = cResponse.getErrorMessage();
            String html = captcha.createRecaptchaHtml(message, null);
            model.addAttribute("profile", profile);
            model.addAttribute(CAPTCHA_HTML, html);
            return "login/register";
        }
        return "ok";
    }

<强 > 模型的一部分(只有此字段被验证)

@NotBlank
    @Size(min=4, max=20)
    @Pattern(regexp="^([\w]+)$")
    private String login;

    @NotBlank
    @Pattern(regexp=("^[_A-Za-z0-9-]+(\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\.[A-Za-z0-9]+)*(\.[A-Za-z]{2,})$"))
    private String email;

如何解决这个问题?
