title: Is RequestMapping not multithreaded?
body: <p>I have a RequestMapping listening web request in my controller, and whenever someone visits my webpage, it will delay the response 5000 milliseconds.</p>
  
  <p>Everything works fine, but when I visit again with a new tab in Chrome at the same time, the second request ends up being delayed 10000 milliseconds. This confuses me, is Spring MVC not multithreaded? Can someone tell me what happened here?</p>
  
  <pre><code>@RequestMapping("/view")
  @ResponseBody
  
  public String View() throws InterruptedException {
      Thread.sleep(5000);
      return "done";
  }
  </code></pre>
