I need help to understand consumers without autowire in spring

[dry solstice]

It's in kotlin. I am beginner in kafka

I can read my kafka message very well with Autowired annotation but on trying to manually create I am getting 0 message .

Code description :
I call val prop=new Properties()
prop.put()
bootstrap server , key-value deserialiser ,schema url
create
consumer = new consumer(props)

then subscribe to topic and poll gives 0 count

but on autowire it gives count

Values are sent during test itself so,that can't be issue

I want to know if manual needs consumwr factory something
