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:
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
.Java
----
@RestController
public class UserController {
@GetMapping("/user")
public MappingJacksonValue getUser() {
User user = new User("eric", "7!jd#h23");
MappingJacksonValue value = new MappingJacksonValue(user);
value.setSerializationView(User.WithoutPasswordView.class);
return value;
}
}

.Kotlin
----
@RestController
class UserController {
@GetMapping("/user")
fun getUser(): MappingJacksonValue {
val value = MappingJacksonValue(User("eric", "7!jd#h23"))
value.serializationView = User.WithoutPasswordView::class.java
return value
}
}
----
For controllers that rely on view resolution, you can add the serialization view class
to the model, as the following example shows:
