Select JsonView in the Spring MVC Controller

Question

I\'m currently writing a REST api using Jackson (2.4.0-rc3) and spring mvc (4.0.3), and I\'m trying to make it secure.

In this way, I try to use JsonView to select

I really like the solution presented here to dynamically select a json view inside your controller method.

Basically, you return a MappingJacksonValue which you construct with the value you want to return. After that you call setSerializationView(viewClass) with the proper view class. In my use case, I returned a different view depending on the current user, something like this:

@RequestMapping("/foos")
public MappingJacksonValue getFoo(@AuthenticationPrincipal UserDetails userDetails ) {
  MappingJacksonValue value = new MappingJacksonValue( fooService.getAll() );
  if( userDetails.isAdminUser() ) {
    value.setSerializationView( Views.AdminView.class );
  } else {
    value.setSerializationView( Views.UserView.class );
  }
  return value;
}

BTW: If you are using Spring Boot, you can control if properties that have no view associated are serialized or not by setting this in your application.properties:

spring.jackson.mapper.default_view_inclusion=true
