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,

MappingJacksonValue value = new MappingJacksonValue(user);
value.setSerializationView(User.WithoutPasswordView.class);
return value;
}
}

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