请求参数与thymeleaf

Question

在Spring Boot网络应用程序中，User想重置他的密码，因此他输入Reset password页面。现在我想让他键入他的电子邮件地址，按Reset，我想重定向到myapp/resetPassword?email=HIS_EMAIL以处理密码重置。

我的代码：

@RequestMapping(value = "/resetPassword", method = RequestMethod.GET) 
public String resetPasswordForm(Model model){ 
    model.addAttribute("email", new String()); 
    return "resetPassword"; 
} 

@RequestMapping(value = "/resetPassword", method = RequestMethod.POST) 
public String resetPassword(@RequestParam("email") String email) { 
    User user = userService.findUserByEmail(email); 
    //playing with logic 
    return "redirect:/"; 
} 

我怎样才能实现呢我thymeleaf网页上？我试过这样的：

<form th:action="@{/resetPassword(email=${email})}" method="post"> 
    <input type="email" th:field="${email}" th:placeholder="Email" /> 
     <div class="clearfix"> 
      <button type="submit">Reset</button> 
     </div> 
</form> 

不幸的是我的email总是空。有人可以帮忙吗？

“th：field”仅适用于Entity-Beans。这应该工作：

@GetMapping(value = "/resetPassword") 
public String resetPassword(@RequestParam(value="email",required=false) String email) { 
    if(email==null) 
     return "resetPassword"; 
    User user = userService.findUserByEmail(email); 
    //playing with logic 
    return "redirect:/";  
} 

<form th:action="@{/resetPassword}" method="get"> 
    <input type="email" th:name="email" th:placeholder="Email" /> 
    <div class="clearfix"> 
     <button type="submit">Reset</button> 
    </div> 
</form> 

并且不要忘记：Thymeleaf不是Javascript。它在服务器上呈现。认为像@{/resetPassword(email=${email})}会输出例如/resetPassword?email=anValueYouAddedToModelInController
