 NOTE: `@JsonView` allows an array of view classes, but you can specify only one per
 controller method. If you need to activate multiple views, you can use a composite interface.
 
+If you want to do the above programmatically, instead of declaring an `@JsonView` annotation,
+wrap the return value with `MappingJacksonValue` and use it to supply the serialization view:

 For controllers that rely on view resolution, you can add the serialization view class
 to the model, as the following example shows:
