Servlet doesn't access to POST method after submit in Spring

This might help you If GET request working with same code, then POST should also work.
You might need to look at below line of code, which may causing for failure
code :
request.getRequestDispatcher("../Views/resultado.jsp").forward(request, response);

html form submit method post and limiting access to the post file

around this issue What you can do is to redirect back to the index.html page when the form is not being posted.
You can do that checking the REQUEST_METHOD variable.
code :
if($_SERVER['REQUEST_METHOD'] !== 'POST')
{
  Header('Location: http://www.mysite.com/index.html');
  exit;
}

around this issue This is my JSP code , you should modify method processForm():
code :
@RequestMapping(value="/multiplebuttons", method = RequestMethod.POST)
public String processForm(  @Validated  ButtonForm buttonForm, BindingResult result,
        Map model) {
    System.out.println("Processing..........");             

    if (result.hasErrors()) {
        System.out.println("Has errors");
        return "multiplebuttons";
    }
    return "redirect:views";
}

Unable to access Spring Security information during a servlet multipart post

Unable to access Spring Security information during a servlet multipart post

I hope this helps you . I can confirm that Spring 3.0.x and Spring Security 3.0.x together work with multipart posts as well as they work with other types of requests. I've run into similar behavior, and in our case, the security filter wasn't getting applied to the request due to our mistake in the filter mappings.
Can you post the parts of your web.xml that define the security filter, and map it to the desired paths?

this one helps. When you POST a form to an HTTP server, the form's contents aren't sent as query parameters; instead, the form is (usually) uploaded as an entity of type application/x-www-form-urlencoded. Instead of using @RequestParam in your method, define a Java class that has fields corresponding to the form fields, and use @ModelAttribute FormClass form.
