title: Use or not leading slash in value for @RequestMapping. Need official docs or point to Spring source?
body: <p>I involved in project where I found a mix of:</p>
  <pre>
  @RequestMapping(value = "events/...");
  @RequestMapping(value = "/events/...");
  </pre>
  <p>(with and without slash before method level annotation).</p>
  <p>I perform search:</p>
  <pre>
  site:http://static.springsource.org/spring/docs/3.1.x  slash
  </pre>
  <p>and read these links:</p>
  <ul>
  <li><a href="http://forum.springsource.org/showthread.php?130753-Various-Spring-MVC-RequestMapping-configuration-questions" rel="nofollow noreferrer">http://forum.springsource.org/showthread.php?130753-Various-Spring-MVC-RequestMapping-configuration-questions</a></li>

  <li><a href="https://www.rfc-editor.org/rfc/rfc6570" rel="nofollow noreferrer">https://www.rfc-editor.org/rfc/rfc6570</a></li>
  </ul>
  <p>But none of these sources answer why skipping slash allowed. Official Spring docs always shown examples with slashes...</p>
  <p>Need point to official docs or to Spring sources.</p>
