帶彈簧和自由標記的驗證表

我已經開始使用spring（3.0.5）窗體，最近使用了hibernate驗證器（4.0.2.GA）。我的驗證工作正常，我可以顯示來自休眠驗證程序的錯誤消息。如何顯示其他消息，如：username and password mismatch和其他消息？這裏是我的表格：帶彈簧和自由標記的驗證表

<form action="loginprocess" method="post"> 
     <h1>Log in</h1> 
     <@spring.bind "loginForm" /> 
     <@spring.showErrors '*', 'errors' /> 
     <p> 
      <label class="uname" data-icon="u"> UserName :</label> 
      <@spring.formInput "loginForm.username","placeholder='eg. myusername'" /> 
      <@spring.showErrors "loginForm.username","error" /> 
     </p> 
     <p> 
      <label class="youpasswd" data-icon="p">Password :</label> 
      <@spring.formPasswordInput "loginForm.password","placeholder='eg. @dakdjlkdja'" /> 
      <@spring.showErrors "loginForm.password", "error" /> 
     </p> 

    <input type="submit" style="background:#000; border: solid 1px #000;" value="Login"/> 
     <p class="change_link"> 
      Not a member yet ? 
     <a href="/site/authentication/signup/form" class="to_register">Sign up</a> 
     </p> 
    </form>

我的控制器看起來是這樣的：

@RequestMapping(value = "/site/authentication/login") 
public ModelAndView nativeLogin(){ 
    LoginForm loginForm = new LoginForm(); 
    return new ModelAndView("login","loginForm",loginForm); 
} 

@RequestMapping(value = "/site/authentication/loginprocess") 
public ModelAndView processNativeLogin(@ModelAttribute @Valid LoginForm loginForm, BindingResult result, Model model){ 
    if(result.hasErrors()){ 

     return new ModelAndView("login","loginForm",loginForm); 
    } 

    try { 
     Subject currentUser = SecurityUtils.getSubject(); 

     if (!currentUser.isAuthenticated()) { 
      UsernamePasswordToken token = new UsernamePasswordToken(loginForm.getUsername(), loginForm.getPassword()); 
      SecurityUtils.getSubject().login(token); 
     } 

    } catch (UnknownAccountException uae) { 
    // how to set this message to show on the form ?"Login Failed! Please check your credentials and try again."); 
    } catch (IncorrectCredentialsException ice) { 
    //"Login Failed! Please check your credentials and try again."); 
    } 
}

任何人都可以闡明如何實現它的一些光？感謝您閱讀本文。

<#if Session.SPRING_SECURITY_LAST_EXCEPTION?? && Session.SPRING_SECURITY_LAST_EXCEPTION.message?has_content> 
      <@spring.message "label.loginerror"/>: ${Session.SPRING_SECURITY_LAST_EXCEPTION.message} 
</#if>

我希望這會有所幫助。
