The invention relates to a message sending method and device based on RabbitMQ, a computer device and a storage medium. The method comprises the following steps of receiving a message and a queue identifier sent by a production end, determining a message queue corresponding to the queue identifier from a plurality of message queues declared in advance; then, delivering the messages needing to be sent by the production end to the message queue; and sending the message to a consumer side bound with the message queue through the message queue, so that the consumer end can process the message sentby the production end, the production end can set the corresponding queue identifier according to the actual demand to send the message to the specific consumption end for processing; all operationsof the production end can hit the specified consumption end, thereby preventing the message of the production end from being polled and sent to a plurality of consumption ends for processing, improving the flexibility of message sending, being able to avoid the concurrency problem only by locking the message on one consumption end, and improving the concurrency performance.
