Hi,

Thank you for sharing.
The consumer can run properly with json format input. However, if I publish a non-json message, it will have problem, the exception stack goes like following.

org.springframework.amqp.rabbit.listener.exception.ListenerExecutionFailedException
org.springframework.amqp.support.converter.MessageConversionException
org.springframework.messaging.converter.MessageConversionException
com.fasterxml.jackson.core.JsonParseException

It's fine for me to see exceptions. I want to catch them and handle by myself. Do you have any idea how to do it? The conversion errors happen inside the jackson2Converter, which is out of control of user code. So I don't know how can I catch these exceptions.

Thanks and Regards,
Ruijie
