How to add JSON request and response examples in Swagger (OpenApi)?

For NelmioApiDocBundle v4 you can do like this

use OpenApi\Annotations as OA;/** * @OA\Parameter( *     name="body", *     in="path", *     required=true, *     @OA\JsonContent( *        type="object", *        @OA\Property(property="property1", type="number"), *        @OA\Property(property="property2", type="number"), *     ), * ) * * @OA\Response( *     response=200, *     description="", *     @OA\JsonContent( *        type="object", *        @OA\Property(property="property1", type="number"), *        @OA\Property(property="property2", type="number"), *     ) * ) */

For v3

use Swagger\Annotations as SWG;/** * @SWG\Parameter( *     name="body", *     in="body", *     required=true, *     @SWG\Schema( *         @SWG\Property(property="test1", type="string"), *         @SWG\Property(property="test2", type="string"), *     ), * ) * * @SWG\Response( *     description="", *     response=200, *     @SWG\Schema( *         @SWG\Property(property="test1", type="string"), *         @SWG\Property(property="test2", type="string"), *     ), * ) */

But better to do it via @Model annotation, as described in the doc if you have DTO or entity.
