title: RequestContextHolder.getRequestAttributes() return null the second time called
body: <p>I have a probleme using the <code>RequestionContextHolder</code>. I have a keycloak token stored in the attributes of the context holder. I get the attributes at that line:</p>
  
  <p><code>RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();</code></p>
  
  <p>I need this keycloak token multiple times.</p>
  
  <p>First, just after login, I get the requestAttributes and then the token (all is fine).</p>
  
  <p>Then I need it later when using the application (after some clicks), the <code>RequestContextHolder.getRequestAttributes()</code> returns null (not so good then). </p>
  
  <p>Id don't understand why the first time all works well and then it just returns null.</p>
  
  <p>I tried to put this in the web.xml but it does not change anything:</p>
  
  <pre><code>&lt;listener&gt;
      &lt;listener-class&gt;org.springframework.web.context.request.RequestContextListener&lt;/listener-class&gt;
  &lt;/listener&gt;
  </code></pre>
  
  <p>Can someone help?</p>
