title: sign up form using spring security
body: <p>I am new to spring, and I have to create a web app using it.
  I started with creating a sign in page using spring MVC/security and hibernate, it works great (I followed a tutorial)
  Now, I want to create sign up page. I tried to do it using the few skills I've learned, but, still, this doesn't work, error 404.</p>
  
  <p>Can anyone please, suggest a tutorial that can help ? or at least a project directory structure ?</p>
  
  <p>Thank you.</p>
