In the process of business process flow, approval type nodes are relatively common. In the approval operation, a common operation is for the supervisor to agree or reject the to-do items. Therefore, the gateway processing node requires preparatory processing of these two approval results. The approval gateway (ApprovalOrSplit) is based on the or branch (OrSplit) and specifically processes the approval type (agree or reject). The difference between it and the or branch The method is: the condition parameters do not need to be configured every time, but the properties of the connection (Transition) can be quickly configured. The advantage of establishing an approval gateway is that it eliminates the need to pass conditional parameters and simplifies the maintenance of condition variables in the programming process. It is worth promoting and using in the process.
