   <div class="layout-container">
      <nav class="navbar navbar-default">
        <div id="navbar">
          <ul class="nav navbar-nav">
            <li class="active"><a href="#">Home</a></li>
            <li><a href="#" data-toggle="modal" data-target="#loginModal">Join us</a></li>
            <li><a href="#">Downloads</a></li>
            <li><a href="#">Rankings</a></li>
            <li><a href="#">Vote</a></li>
            <li><a href="#">Community</a></li>
          </ul>
        </div><!--/.container-fluid -->
      </nav>

      <div class="container">
        <div class="layout-sidebar">
          <div class="side-control">
            <header><h2>Sidebar</h2></header>

            <div class="side-content">
              Content here
            </div><!--/.side-content -->
          </div><!--/.side-control -->
        </div><!--/.layout-sidebar -->

        <div class="col-md-9">
          Content here
        </div><!--/.col-md-9 -->
      </div><!--/.container -->
    </div><!--/.layout-container -->

and on the clien side i send a request:

@RequestMapping(value = "/event", method = RequestMethod.POST , produces = MediaType.APPLICATION_JSON_VALUE)
    public void bookOpened(
            @RequestParam(value="id", required = true) int id,
            @RequestParam(value="type", required = true) String type,
            HttpServletRequest request, HttpServletResponse response, HttpSession httpSession) {

    }

requests end with error 400(bad request) and i dont know why

You need to use @RequestBody annotation in method parameters. For more info see, for example, here: Parsing json into java objects in spring-mvc
