title: what is the dif between requestMapping on controller and method
body: <p>If I have:</p>
  
  <pre><code>@RequestMapping("/user")
  public class RegistrationController {
  
     @RequestMapping(value = "/register", method = RequestMethod.GET)
     public String getRegisterPage(Model model) {
  </code></pre>
  
  <p>What is the difference? I mean what will happen if I remove the <code>/user</code> mapping, will my <code>/register</code> mapping still work?</p>
