Calling Camel route from service via Java interface

[Sobkowiak, Krzysztof]

Hi

I'd like to call a Camel route from a Spring bean. One method is using 
the ProducerTemplate like in this demo [1]

In Camel 2.x it was possibly to define a Java interface and use it to 
call the route (CamelProxy). I can't find it in actual documentation. 
Was this functionality removed from in Camel 3?

Best regards

Krzysztof
