Research direction
Start with com.github.paicoding.forum.service.notify.service.impl.RabbitmqServiceImpl and inspect the consumerMsg method's RabbitMQ initialization. Reproduce the startup with a local RabbitMQ instance that does not already contain direct.exchange, then verify that initialization no longer fails with the reported missing-exchange error.
