  </code></pre>
  
  <p>Instead of the application throwing the exception I would like to handle the exception and send a custom error message to the user. I already have a ExceptionHandler class to handle any errors thrown within a controller</p>
  
  <pre><code>@ControllerAdvice
  public class RestExceptionHandler extends ResponseEntityExceptionHandler {
  
  //code
  
  }
  </code></pre>
  
  <p>However this exception is thrown outside controller method so it is not being handler by the RestExceptionHandler class. So how do I check if the user's token is expired and then send a custom error response to the user?</p>
