Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as presented in the figures, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In consideration of the practical application scenario, it is difficult for business personnel to independently adjust or edit the workflow, and the change of the process usually requires the participation of technical personnel, so that the working efficiency is low. Based on this, the embodiment of the application provides a method and an apparatus for generating a workflow, an electronic device and a readable storage medium, so as to improve convenience of business personnel in adjusting or editing the workflow, and further improve work efficiency. The following is a description by way of example.

The first embodiment is as follows:

for the convenience of understanding the present embodiment, a method for generating a workflow disclosed in the embodiments of the present application is first described in detail. Fig. 1 shows a flowchart of a method for generating a workflow provided in an embodiment of the present application, and as shown in fig. 1, the method includes the following steps S1 to S4:

step S1: acquiring an initial workflow; the initial workflow is drawn through a target workflow designer; the target workflow designer is a workflow designer that masks the gateway node.

The workflow is to organize a group of tasks to accomplish a certain business objective, wherein a triggering sequence and triggering conditions of the tasks are defined, documents and information are allowed to be transmitted between different departments and roles, and a unified interface is provided for functions of process approval, flow circulation, rollback and the like. When the workflow is applied to a business system, a flow chart needs to be designed firstly, wherein the design process is carried out in a visual mode, different types of flow nodes are dragged to the flow chart, and the branches and the trends of the flow are determined through connecting lines.

The existing workflow designer usually includes gateway nodes (e.g., parallel gateway nodes and exclusive gateway nodes) that are difficult for service personnel to understand and use, which causes a problem that it is difficult for service personnel to independently adjust or edit workflows. At this time, the node types in the target workflow designer include only: the system comprises a starting node, an ending node, a user approval node, an automatic task processing node, a condition judgment node, a countersigning node and a sub-process node. At this time, the business person can draw the initial workflow independently by using the target workflow designer only by dragging and pulling.

The automatic task processing node is used for automatically processing data or tasks which flow to the node according to a preset processing rule, and the automatic task processing node comprises the preset processing rule. The condition judgment node may set a judgment condition. The countersigning node adopts a voting mechanism, for example, one approval task is distributed to 5 persons, the 5 persons all process the approval task to obtain 5 approval results, the 5 approval results are counted, the approval results are the approved quantity, and whether the approval is passed or not is determined according to the quantity (for example, when the quantity is at least 3, the approval is passed). The sub-process node means that when the same section of process appears in different places in one process, the section of process is set as a sub-process, and the sub-process can be called repeatedly.

In this embodiment, the gateway node includes a parallel gateway node and an exclusive gateway node, and there are a plurality of next nodes connected to the gateway node in the normal flow direction of the workflow. The parallel gateway node is used for enabling each next node connected with the parallel gateway node to execute own task. The exclusive gateway node is used for enabling the next node meeting the judgment condition to execute the task of the exclusive gateway node in each next node connected with the parallel gateway node. Taking an approval process as an example, the next nodes connected with the gateway node are respectively a group leader approval node and a project manager approval node, when the gateway node is a parallel gateway node, both the group leader approval node and the project manager approval node need to execute an approval task, and when the gateway node is an exclusive gateway node, one of the group leader approval node and the project manager node can execute the approval task.

In a possible implementation manner, before the step S1 is executed to obtain the initial workflow, the following steps may be further executed:

s0: receiving an initial workflow sent by a first user end so as to store the initial workflow; the initial workflow is drawn by a first user through a target workflow designer installed in a first user side; a plurality of initial workflows are stored in the back-end server; each initial workflow corresponds to a respective flow type.

In this embodiment, the target workflow designer is installed in the first user side, and the first user may draw, according to a required flow type (i.e., a business target, such as a leave approval flow), an initial workflow corresponding to the flow type through the target workflow designer installed in the first user side.

After a first user uses first user terminals to draw initial workflows, the initial workflows are sent to a back-end server through the first user terminals, and the back-end server receives the initial workflows sent by the first user terminals so as to store the initial workflows.

In a possible embodiment, when the step S1 is executed to obtain the initial workflow, the following steps S101 to S102 may be specifically executed:

s101: and receiving an inquiry request sent by the second user end to return a plurality of initial workflows stored in advance and the number corresponding to each initial workflow to the second user end, so that the second user end responds to the selection operation of the second user on the initial workflows, and sends the number corresponding to the selected initial workflows as a target number to the back-end server.

In this embodiment, the second ue may be the first ue or another ue except the first ue. And when the workflow deployment operation is required, the second user sends a query request to the back-end server through the second user side. And after receiving the query request, the back-end server returns a plurality of pre-stored initial workflows and the number corresponding to each initial workflow to the second user end. The second user selects an initial workflow corresponding to the process type from the initial workflows displayed on the second user according to the process type of the workflow required to be deployed (for example, the process type required to be deployed is a leave-on approval process), and the second user sends the number of the initial workflow corresponding to the process type as a target number to the back-end server.

S102: and receiving a target number sent by the second user end so as to obtain an initial workflow corresponding to the target number from a plurality of initial workflows stored in advance.

After receiving the target number sent by the second user, the back-end server obtains an initial workflow corresponding to the target number (i.e., the process type) from a plurality of pre-stored initial workflows.

Step S2: inquiring a node with a null front node in the initial workflow to determine the node as an initial node and take the initial node as a first node; the front node is used for representing a node which is before the current node in the flow direction relation of the initial workflow.

In a possible embodiment, before the step S2 is executed to query a node in the initial workflow, where a front node is empty, so as to determine the node as a start node, the following step S201 may be further specifically executed:

s201: analyzing the node relation in the initial visual workflow, determining the prepositive nodes of all the nodes in the initial visual workflow, and storing the node relation between all the nodes and the prepositive nodes of all the nodes in a database. The node relationship refers to which node the front node of each node is.

When step S2 is executed to query a node in the initial workflow, where a front node is empty, so as to determine the node as a start node, the following step S202 may be specifically executed:

s202: and querying a node with a null front node in the initial workflow from the node relation stored in the database so as to determine the node as an initial node.

Fig. 2 shows a schematic diagram of an initial workflow provided by an embodiment of the present application, and as shown in fig. 2, a front node of a node a is an initial node, a front node of a node B is a node a, a front node of a node C is a node B, and front nodes of a node G are a node E, a node F, and a node D.

In this embodiment, the start node has no front node, that is, the front node of the start node is empty, so that the start node can be determined by querying the node in the initial workflow, where the front node is empty.

And step S3: a node adjacent to and subsequent to the first node in the initial workflow is determined to be a second node.

In this embodiment, the first node determined in the previous step is the start node, and the node adjacent to and after the start node in the initial workflow is node a, and at this time, node a is determined as the second node.

And step S4: determining a processing mode corresponding to the second node according to the connection relationship between the first node and other nodes in the initial workflow and the connection relationship between the second node and other nodes, and processing the second node through the processing mode; and repeatedly executing the step S3 to the step S4, and in the repeated execution process of the step S, determining the second node in the step S3 as a new first node, and stopping circulation until a target workflow meeting the preset specification is generated.

In this embodiment, the preset specification is specifically a BPMN2.0 (Business Process Modeling and labeling) specification.

In a possible implementation manner, when the step S4 is executed to determine a processing manner corresponding to the second node according to the connection relationship between the first node and the other nodes in the initial workflow and the connection relationship between the second node and the other nodes, so as to process the second node through the processing manner, the following step S401 may be specifically executed:

s401: and when the first node only belongs to the front node of one node, establishing a connection line between the first node and the second node.

For example, as shown in fig. 2, when the first node is a start node and the second node is a node a, since the start node only belongs to a front node of the node a, fig. 3 illustrates a schematic diagram of a target workflow provided in the embodiment of the present application, and as shown in fig. 3, a connection line between the first node (start node) and the second node (node a) is established.

In this embodiment, if the node type of the first node is any one of the following: and the connection line between the first node and the second node is directly established by the starting node, the user approval node and the condition node. If the node type of the first node is any one of the following: and then, establishing a connection between the first node and the second node (namely, establishing a connection between the first node and the user approval node (node H) and establishing a connection between the user approval node (node H) and the second node).

Next, the second node (node a) is determined as a new first node. And continuing to execute the following steps: nodes in the initial workflow that are adjacent to and behind the new first node (node a) are determined to be new second nodes. As shown in fig. 2, the new second node is determined to be node B.

Since the node a (first node) belongs only to the front node of the node B (second node), a connection between the first node (node a) and the second node (node B) is established as shown in fig. 3. The second node (node B) is then considered as the new first node. And continuing to execute the following steps: nodes adjacent to and subsequent to the new first node (node B) in the initial workflow (i.e., nodes C and D) are determined as new second nodes.

In a possible embodiment, when the step S4 is executed to determine a processing manner corresponding to the second node according to the connection relationship between the first node and the other nodes in the initial workflow and the connection relationship between the second node and the other nodes, and process the second node by the processing manner, the following steps S402 to S404 may be specifically executed:

s402: when the first node belongs to a front node of at least two nodes, judging whether the node type of the first node is a condition judgment node;

s403: when the node type of the first node is not the condition judgment node, establishing a first gateway node with the node type being a parallel gateway node, and establishing a connection line between the first node and the first gateway node; respectively establishing a connection line between the first gateway node and each second node aiming at each second node, and pressing the first gateway node into the current stack according to a first-in-first-out principle; the first gateway node is used for sending task starting information to each second node connected with the first gateway node when receiving the task completion information sent by the first node, so that each second node starts to execute the corresponding task to be executed;

s404: when the node type of the first node is a condition judgment node, establishing a second gateway node of which the node type is an exclusive gateway node, and establishing a connection line between the first node and the second gateway node; establishing a connection line between a second gateway node and each second node aiming at each second node, and pressing the second gateway node into the current stack according to a first-in-first-out principle; the second gateway node is used for selecting a target second node corresponding to the condition judgment result from a plurality of second nodes connected with the second gateway node according to the condition judgment result sent by the first node, and sending task starting information to the target second node so as to enable the target second node to start to execute the task to be executed corresponding to the target second node.

In this embodiment, the node B (first node) belongs to the front nodes of the node C and the node D, and at this time, it is determined whether the node type of the first node (node B) is a conditional determination node. As shown in fig. 2, the node type of the node B in this embodiment is not a conditional judgment node. At this time, as shown in fig. 3, a first gateway node (e.g., B1) whose node type is a parallel gateway node is created, and a connection between the node B (first node) and the first gateway node B1 is established, and a connection between the first gateway node B1 and a node C (second node) is established, and a connection between the first gateway node B1 and a node D (second node) is established. And pushing the first gateway node B1 into the current stack according to a first-in-first-out principle.

The stack exists as a space, and the arrangement of each node in the stack is arranged according to the principle of first-in and last-out. In this embodiment, the first gateway node B1 is placed in the current stack according to a first-in-first-out principle, and at this time, the first gateway node B1 is a current stack top node in the current stack.

Then, taking the second node (node C) as a new first node, the following steps are carried out: and determining the nodes (namely the conditional judging nodes) adjacent to and behind the new first node (the node C) in the initial workflow as new second nodes. As shown in fig. 2, since the node C (first node) only belongs to the front node of the condition judging node (second node), as shown in fig. 3, a connection line between the first node (node C) and the second node (condition judging node) is established. And taking the condition judgment node as a new first node.

Nodes (node E and node F) adjacent to and subsequent to the new first node (conditional judging node) in the initial workflow are determined as second nodes. At this time, the first node (conditional judgment node) belongs to the front node of the two nodes, and thus it is judged whether the node type of the first node is a conditional judgment node.

In this embodiment, the node type of the first node (conditional judgment node) is a conditional judgment node, and at this time, the second gateway node C1 whose node type is an exclusive gateway node is created, as shown in fig. 3, a connection line between the conditional judgment node and the exclusive gateway node C1 is established.

For the second node (node E), a connection line between the second gateway node C1 and the second node (node E) is established, and the second gateway node C1 is pushed into the current stack according to a first-in-first-out principle. At this time, in this embodiment, in the current stack, the second gateway node C1 is above the first gateway node B1, and the second gateway node C1 is a current stack top node in the current stack.

Taking the second node (node E) as a new first node, continuously executing the following steps: a node (node G) in the initial workflow that is adjacent to and behind the new first node (node E) is determined as the second node.

In a possible implementation manner, when the step S4 is executed to determine a processing manner corresponding to the second node according to the connection relationship between the first node and the other nodes in the initial workflow and the connection relationship between the second node and the other nodes, so as to process the second node through the processing manner, the following steps S405 to S407 may be specifically executed:

s405: when the first node and other nodes are jointly used as the front node of the second node, judging whether a current stack top node exists in a current stack;

s406: if the current stack top node exists, acquiring the current stack top node, continuously judging whether the current stack top node exists in the current stack or not and subsequent steps, stopping until the current stack top node does not exist in the current stack, and acquiring the stack popping sequence of each current stack top node and each current stack top node;

s407: judging whether a third node with the same type as the current stack top node exists at present or not aiming at each current stack top node; if the third node with the same node type as the current stack top node does not exist, the third node with the same node type as the current stack top node is created to obtain a third node corresponding to each current stack top node; according to the pop sequence of each current stack top node, sequentially passing through a third node corresponding to each current stack top node, and establishing a connection line between the first node and the second node; and if the third node exists, establishing a connection line between the first node and the second node sequentially through the third node corresponding to each current stack top node according to the pop-up sequence of each current stack top node.

In this embodiment, since the first node (node E) and the other nodes (node F and node D) together serve as the front node of the second node (node G), it is determined whether the current stack top node exists in the current stack. In this embodiment, if a current stack top node, specifically, a second gateway node C1, exists in the current stack, the second gateway node C1 is obtained. And continuing to judge whether the current stack has the current stack top node, in this embodiment, if the current stack has the current stack top node, specifically, the current stack top node is the first gateway node B1, then the first gateway node B1 is acquired. And continuing to judge whether the current stack top node exists in the current stack, wherein in the embodiment, the current stack top node does not exist in the current stack, and stopping continuing to judge. In this embodiment, the pop sequence of the first gateway node B1 and the second gateway node C1 is the first pop of the second gateway node C1 and the second pop of the first gateway node B1.

For the second gateway node C1, in the process of converting the initial workflow into the target workflow, it is determined whether a third node (note that the third node is not the second gateway node) of the same type as the node of the second gateway node C1 exists in the target workflow currently in the conversion process. As shown in fig. 3, when there is no third node of the same node type as the second gateway node C1, a third node of the same node type as the second gateway node C1 is created (i.e., a third node C2 of which the node type is an exclusive gateway node is created).

And aiming at the first gateway node B1, judging whether a target workflow currently in the conversion process has a third node with the same node type as that of the first gateway node B1. When there is no third node of the same node type as the first gateway node B1, a third node of the same node type as the first gateway node B1 is created (i.e., a third node C2 of parallel gateway node type is created). At this time, the third nodes (B2 and C2) corresponding to each current top-of-stack node (the first gateway node B1 and the second gateway node C1) are obtained.

As shown in fig. 3, according to the pop sequence of the second gateway node C1 (first pop) and the first gateway node B1 (second pop), the connection between the first node E and the second node G is established sequentially through the third node C2 and the third node B2.

The second node (node G) is taken as the new first node. And continuing to execute the following steps: a node (end node) adjacent to and behind the new first node (node G) in the initial workflow is determined as a second node, as shown in fig. 2, and since the second node (node G) only belongs to the front node of the end node, as shown in fig. 3, a connection line between the node G and the end node is established.

After the connection between the conditional judgment node and the second gateway node C1 is established, for the second node (node F), the connection between the second gateway node C1 and the second node (node F) is established, and the second gateway node C1 is pushed into the current stack according to the first-in-last-out principle. At this time, the current stack includes the second gateway node C1. Taking the second node (node F) as a new first node, continuously executing the following steps: a node (node G) in the initial workflow that is adjacent to and behind the new first node (node F) is determined as the second node.

In this embodiment, since the first node (node F) and the other nodes (node E and node D) together serve as the front node of the first node (node G), it is determined whether the current stack top node exists in the current stack. In this embodiment, if a current stack top node, specifically, a second gateway node C1, exists in the current stack, the second gateway node C1 is obtained, and whether the current stack top node exists in the current stack is continuously determined. In this embodiment, only one current top node of the stack, that is, the second gateway node C1, is present, that is, the pop sequence is the first pop of the second gateway node C1.

And judging whether a third node with the same node type as the second gateway node C1 exists in the current target workflow. At this time, when a third node (i.e., the third node C2) of the same node type as the second gateway node C1 exists in the current target workflow, a connection line between the first node (node F) and the second node (node G) is established through the third node C2.

After the connection between the node B and the first gateway node B1 is established, for the second node (node D), the connection between the first gateway node B1 and the second node (node D) is established, and the first gateway node B1 is pushed into the current stack according to the first-in-last-out principle. At this point, only the first gateway node B1 is contained in the current stack.

Taking the second node (node D) as the new first node, as shown in fig. 2, the following steps are carried out: a node adjacent to and subsequent to the first node (node D) in the initial workflow (i.e., node G) is determined as the second node.

In this embodiment, since the first node (node D) and the other nodes (node E and node F) together serve as the front node of the second node (node G), it is determined whether the current stack top node exists in the current stack. In this embodiment, if a current stack top node, specifically, a first gateway node B1, exists in the current stack, the first gateway node B1 is obtained, and whether the current stack top node exists in the current stack is continuously determined. In this embodiment, only one current top node, that is, the first gateway node B1, exists, that is, the pop sequence is the first pop of the first gateway node B1.

And judging whether a third node of the same node type as the first gateway node B1 exists currently. In this embodiment, when there is a third node (i.e., a third node B2) of the same node type as the first gateway node B1, a connection between the first node (node D) and the second node (node G) is established through the third node B2 corresponding to the first gateway node B1.

Through the above method, as shown in fig. 3, a target workflow conforming to a preset specification is generated. And deploying and releasing the target workflow, and then online applying.

In this embodiment, the target workflow may be deployed to a backend server, or the target workflow may be sent to other clients (specifically, the first client or the second client, or clients other than the first client and the second client) through the backend server to be deployed to other clients.

As shown in fig. 3, after the target workflow is deployed online, the target workflow may be executed in the following manner:

when the starting node is triggered, the starting node sends task starting information to the node A, and the node A executes the task after receiving the task starting information. Illustratively, when a task of a node a is a user approval task, the node a sends the approval task to a user side of a corresponding approver, after the approver executes the approval task, a task execution result is returned to the node a through the user side, and when the task execution result is approved, the node a sends task completion information to a node B, so that the node B executes its own task. When the node B finishes the task of the node B, task completion information is sent to the node B1, and when the node B1 receives the task completion information sent by the node B, task start information is sent to the node C and the node D respectively, so that the node C and the node D start to execute the tasks to be executed corresponding to the node C and the node D.

After the node C finishes the task, task completion information is sent to the condition judgment node, the condition judgment node starts to execute the judgment task of the node C, and the condition judgment result is sent to the node C1. And the node C1 selects a target node (assumed as the node E) corresponding to the condition judgment result from the node E and the node F according to the condition judgment result, and sends task starting information to the node E so that the node E starts to execute the task to be executed corresponding to the node E. After the node E executes the task of the node E, task completion information is sent to the node C2. After receiving the task completion information sent by any one of the node E or the node F, the node C2 sends the task completion information to the node B2.

After the node D executes its own task, it sends task completion information to the node B2. After receiving the task completion information sent by the node C2 and the node D, the node B2 sends the task completion information to the node G, so that the node G starts to execute its own task. And after the node G finishes the task of the node G, sending task finishing information to the finishing node, and after the finishing node receives the task finishing information, finishing the process execution.
