body: <p>How to get all exception handlers annotated by @ExceptionHanlder and I can call them manually?</p>
  
  <p><strong>Background</strong><br>
  I need to handle some exceptions by my own exception handlers but in some situation my handled exceptions are not thrown directly by spring, and they are wrapped in the cause by. So I need to handle these caused by exceptions in one place using my own exception handling strategy in the existing <code>@ExceptionHandler</code>s. How can I do that?</p>
