Document how to specify Jackson JSON view serialization hints with @RestController and Webflux

[monstrfolk]

There is not documentation how to filter fields using JsonViews using specific security roles when using Webflux and non-functional endpoints, for example @RestController.

There is a tutorial that explains how to achieve this using MCV.

There is another issue that has been closed that explains similar functionality with RouterFunctions and Webflux.

@monstrfolk you have seen JSON Views section in the docs?

How can the JsonView be set within the controller method or dynamically at runtime?

Would like to set the view dynamically based off of some other property. The 2 examples in original post support dynamically setting the JsonView.

I see. Have you tried returning MappingJacksonValue from the controller? That should work.

@rstoyanchev, thanks for you help. Could you please provide an example?

@RestController
public class FooController {

	@GetMapping("/")
	MappingJacksonValue handle() {
		Foo foo = new Foo();
		return new MappingJacksonValue(foo);
	}
}
