The invention relates to the technical field of servers, and discloses a
workflow instance starting method, device and equipment and a
service system. The method comprises the following steps: starting and sending an approval service request to a
message queue, wherein the approval process is at least the same as the approval process of a second service; monitoring a response message fed back by the
workflow service in real time in the
message queue according to a preset association relationship, the preset association relationship including a corresponding relationship between each
type of service and a theme; and when a
target response message corresponding to the approval service request is monitored, analyzing the
target response message, determining that the
workflow instance corresponding to the approval service request is successfully started according to the content in the
target response message, and executing the approval operation of each node in the workflow instance according to the workflow instance. According to the method, the starting of the approval process is more accurate and efficient. Moreover, the code change of one party does not affect the code of the other party, so that the code
processing time is shortened, and the workflow instance starting and approval efficiency is improved.
