How to inject Producer to Interceptor in a custom extension

[mariuszbozek]

Hi,

I have a problem with the right implementation of Interceptor in my custom extension.
In my interceptor, I would like to inject my custom producer (with Kafka producer) but when I use this extension in my application on startup this custom producer is always null and nothing happens when the @AroundInvoke method in the interceptor is invoked.

How I should build my extension to be sure that on run time in the interceptor, a producer is already initialized
