title: Get information from AOP @Before in Controller
body: <p>I have a controller that I have written an AOP on. My controller would read something like -</p>
  <pre><code>@Operation(operation=&quot;foo&quot;)
  @GetMapping(&quot;/abc/def&quot;)
  public void getFoo() {
      ...
  }
  </code></pre>
  <p>The corresponding <code>@interface</code> for <code>Operation</code> has been created.</p>
  <p>My aspect looks something like -</p>
  <pre><code>@Before(&quot;@annotation(operation)&quot;)
  public void beforeOperation(ProceedingJoinPoint pjp, Operation operation) {
      Data data = restService.getData();
  }
  </code></pre>
  <p>I make a HTTP call in the aspect to get <code>data</code>. Is there a way I can let this <code>data</code> be accessible to the controller without having to make that HTTP call again?</p>
