The invention discloses a message passing method and device and a readable storage medium, and relates to the field of electronic information.A message sender is controlled to send an original message to an intermediate component, then the intermediate component forwards the original message to message middleware and stores the original message in a database, and whether a message receiver receives the original message or not is judged, so that the original message is transmitted to the intermediate component. If the original message is not received, the original message is sent to the message receiver through the database, and compared with the previous mode that the message is transmitted directly through the message middleware, the original message can be sent to the message receiver through the database even if abnormal conditions such as message middleware faults and network fluctuation occur, so that the message is prevented from being lost or failed to flow, and the service life of the message is prolonged. And the storage capacity of the database is far greater than the data storage capacity of the message-oriented middleware, and when the service flow is large, the original message can be sent to the message receiver through the database, so that the accumulation of the original message in the message-oriented middleware is relieved, and the timely consumption of the message and the reliability of message transmission are ensured.
