title: URL change encoding + instead of %20
body: <p>URL encoding normally replaces a space with a plus (+) sign or with %20.
  In spring MVC it replaces with %20. My controller as:</p>
  
  <pre><code>@GetMapping(path = "/post/{id}/{title}")
  public String postView(@PathVariable("id") Long id, @PathVariable("title") String title, Model model){
  
  
      Post post = postService.findById(id);
      model.addAttribute("post", post);
      return "singlePost";
  }
  </code></pre>
  
  <p>I need to replace the %20 with (+) or (-)
  Thanks </p>
