Priority-based data message publishing method and system according to a data message chain

A priority-based data message publishing method according to a data message chain can be implemented by receiving a data message, wherein the data message has an original priority. Then, judge whether there is a corresponding data message chain corresponding to the data message. When there is a corresponding data message chain, add the data message to the back of the corresponding data message chain to obtain a revised data message chain. When there is no corresponding data message chain the data message, add a new data message chain, and add the data message to the back of the new data message chain to obtain a revised data message chain. Next, rule-operate the revised data message chain to obtain a dynamic priority of the data message. Replace the original priority with the dynamic priority to obtain a revised data message. Publish the revised data message according to the dynamic priority.
