title: For OpenAPI (swagger-php), how do I auto generate query parameters?
body: <p>I am writing an OpenAPI spec and trying to generate my possible query parameters automatically (using swagger-php) from the annotations for a request route/path. I know that I can just type out all possible parameter options for each route, but I really need to be able to generate the possible parameters from the properties of a class automatically using annotations like I can do for the request body. (We will have tons of classes/paths and keeping it up to date most likely won't happen unless they are generated like the request body/JsonContent can be. Is this possible with swagger-php or even OpenAPI in general?</p>
  
  <p>I got this to work with the put and the request body, but how do I do it for a get request that still uses the properties of the class?</p>
  
  <p>I can do this for the request body:</p>
  
  <pre class="lang-php prettyprint-override"><code>    /**
       * @return Response
       *
       * * @OA\Put(
       *     path="/persons",
       *     tags={"Person"},
       *     @OA\RequestBody(
       *          request="person",
       *          required=false,
       *          description="Optional Request Parameters for Querying",
       *          @OA\JsonContent(ref="#/components/schemas/Person")
       *      ),
       *     @OA\Response(
       *          response="200",
       *          description="Returns matching Person Object",
       *          @OA\JsonContent(
       *              type="array",
       *              @OA\Items(ref="#/components/schemas/Person")
       *          )
       *     )
       * )
       */
  </code></pre>
  
  <p>Writing out each parameter for 30+ classes will not be maintainable:</p>
  
  <pre class="lang-php prettyprint-override"><code>     /** @OA\Get(
       *     path="/events",
       *     tags={"Events"},
       *     @OA\Parameter(
       *          name="eventID",
       *          in="query",
       *          required=false,
       *          description="The event ID specific to this event",
       *          @OA\Schema(
       *              type="string"
       *          ),
       *     ),
      *
     * ....etc
  </code></pre>
