Channel channel = (Channel)message.getHeaders().get(AmqpHeaders.CHANNEL);

This way I am creating the channel, I have a application.yml file where I set all the binding properties. Can any tell me the reason about this ?

1.7.1 disables auto recovery by default (unless you inject a preconfigured Rabbit ConnectionFactory into the CachingConnectionFactory ).

It was incorrectly enabled by default in 1.7.0.

Spring AMQP doesn't need autorecovery, it has had its own connection recovery mechanisms since 1.0.

The current 1.7.x version is 1.7.6; the current (preferred) version is 2.0.2.

This doesn't explain the EOFException (auto recovery still, normally, works - it's just not needed).
