Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart illustrating a flow analysis method according to an embodiment of the present disclosure. As shown in fig. 1, the method includes:
in S11, the first flow node receives a first completion message sent by a message center, where the first completion message includes identification information of a second flow node whose operation is completed, and the message center is configured to send a completion message from a message publisher to a message subscriber corresponding to the completion message, where the completion message from the message publisher includes the identification information of the message publisher. The message center can store the completion message from the message publisher through the message queue, the second process node is used as the message publisher of the completion message, and the first process node is the message subscriber of the completion message. The identification information of the message publisher may be a process node ID of the message publisher, which is not limited by the present disclosure.
Optionally, after publishing the message in the message queue to the corresponding message subscriber, the message center may remove the completion message from the message queue, so as to improve the utilization rate of the storage space and prevent the message subscriber from repeatedly acquiring the completion message.
Illustratively, at the start of a flow, a flow instance of the flow may be initialized. Specifically, the initialization may be performed as follows:
initializing all process nodes in the process instance, namely setting the states of all process nodes as initial states; and determining a front node corresponding to each flow node according to the association relationship between the flow nodes, where the front node is a node that has a direct association relationship with the current flow node and runs before the current flow node, as shown in fig. 2, the front node of the flow node K is a flow node E, and the front node of the flow node E is a flow node A, B, C. At the same time, each flow node registers a subscription message with the message center to subscribe to "completion messages" from the message center. The message subscriber corresponding to the completion message is the flow node currently subscribing the completion message in the message center. As shown in fig. 2, initially, the message subscribers are all flow nodes in the flow instance.
In S12, if it is determined that the second flow node is the front-end node of the first flow node according to the identification information of the second flow node, it is determined whether the operations of all the front-end nodes of the first flow node have been completed.
Where the front-end node for each flow node has been determined at the initialization of the flow instance, as described above. Therefore, the first flow node may determine whether the identification information is the same as the identification information of the previous node of the first flow node according to the identification information of the second flow node included in the first completion message. If the first completion message is the same as the second completion message, the second flow node is the front-end node of the first flow node, and if the first completion message is not the same as the second completion message, the second flow node is not the front-end node of the first flow node.
In S13, if the operations of all the front nodes of the first flow node are completed and the execution condition of the first flow node is satisfied, the operation of the first flow node is executed.
When the number of the front nodes of the first flow node is multiple, the first flow node may be executed after the operations of the front nodes are determined to be completed.
Optionally, if the front node of the first flow node is one and the front node is the judgment node, the execution condition of the first flow node is as follows: the status of the front node of the first flow node is a finished status, and the first flow node satisfies the judgment result of the front node.
If the front node of the first flow node does not include the judgment node, the execution condition of the first flow node is as follows: at least one preposed node with the state of completion exists in the preposed nodes of the first flow node.
If the front nodes of the first flow node are multiple and include the judgment node, the execution condition of the first flow node is as follows: at least one preposed node with the state of completion exists in the preposed nodes of the first flow node, and when the preposed node with the state of completion is a judgment node, the first flow node meets the judgment result of the judgment node.
In the above technical solution, the message communication between each process node in the process is realized by completing the publishing and subscribing of the message, the current process node may determine whether the completion message is published by its front node according to the identification information included in the completion message, and when the operations of all the front nodes of the current process node are completed and the execution conditions of the current process node are satisfied, the operation of the current process node is executed. Therefore, on one hand, flow analysis can be dispersed to each flow node drive, the concentration and the complexity of the flow analysis are reduced, on the other hand, message communication among all flow nodes in the flow is realized by completing publishing and subscribing of messages, and the operation among the flow nodes can be realized by directly sending a trigger message to the rear node through the current node without needing to clarify the front node and the rear node of the current flow node as in the prior art, so that the efficiency and the data processing amount of the flow analysis are improved, and the accuracy of the flow analysis is further ensured.
Optionally, the method further comprises:
and if the operation of all the front nodes of the first flow node is finished, sending a subscription ending message to the message center, wherein the subscription ending message comprises the identification information of the first flow node, and the subscription ending message is used for canceling the identity of the message subscriber of the first flow node by the message center.
The operations of all the front nodes of the first flow node are completed, and no matter whether the first flow node is executable or not, the first flow node does not need to receive the completion messages of other flow nodes, so that the first flow node can send a subscription completion message to the message center. When the message center receives the subscription ending message, the message subscriber identity of the first process node is cancelled according to the identification information of the first process node, so that the first process node does not receive the completion message from the message center any more, the waste of data transmission resources caused by receiving excessive unnecessary completion messages can be avoided, the data distribution quantity of the message center can be effectively reduced, the data quantity of process data analysis is reduced, and the efficiency of process analysis is improved.
Optionally, the method further comprises:
after the operation of the first flow node is executed, the state of the first flow node is updated to a completion state, and a second completion message is sent to the message center, so that the message center can distribute the second completion message to a corresponding message subscriber when receiving the second completion message, and other flow nodes can timely know that the operation of the first flow node is completed; or
If the operation execution of the first flow node is abnormal, updating the state of the first flow node into an abnormal termination state, and sending a second completion message to the message center, wherein the operation execution abnormality can be an abnormality that the operation cannot be continuously executed due to insufficient memory, program interruption and the like; or
And if the first flow node is not executable, updating the state of the first flow node to an execution prohibition state, and sending a second completion message to the message center, wherein the second completion message comprises the identification information of the first flow node.
If the first flow node is the flow node I, the number of the front-end nodes of the flow node I is one, and the front-end node is the determination node K, and if the determination result of the determination node K is tune, since the flow node I is the flow node corresponding to the determination result FALSE, the determination result of the front-end node is not satisfied, and the state of the flow node I is updated to the execution prohibition state.
For another example, if the first flow node is the flow node H, and there is no front node with a finished state in the front nodes corresponding to the flow node H (the front node is the flow node I, and the state of the flow node I is the execution-prohibited state), the flow node H is not executable, and the state is updated to the execution-prohibited state.
In the above technical solution, the state of the first flow node is updated according to different execution results of the operation of the first flow node, on one hand, data support can be provided for the analysis of the subsequent flow node, and on the other hand, the state of the first flow node can be updated in time, which is convenient for the backtracking of the subsequent flow and the exception handling and checking of the flow node.
Optionally, the determining whether the operations of all front nodes of the first flow node are completed includes:
traversing the states of all front nodes of the first flow node;
as shown in fig. 2, when the first flow node is flow node E, the front node of flow node E determined during initialization is A, B, C.
Wherein the states of all the front nodes traversing the first flow node can be traversed in the following manner:
and selecting any front node as the front node of the current traversal, and determining the state of the front node of the current traversal. Illustratively, the front node currently traversed is flow node a.
If the current traversed front node is in the complete state or the execution prohibition state, one of the non-traversed front nodes is selected as the current traversed front node, and the steps are executed again. For example, if the state of flow node a is in the complete state, a node is selected from flow node B, C as the previous node of the current traversal, and if the state of flow node C is determined to be in the complete state, flow node B is taken as the previous node of the current traversal.
And if the state of the current traversed front node is not a completion state or a forbidden execution state, ending the traversal.
For example, if the state of the flow node B is the running state, it indicates that the operation corresponding to the flow node B is being executed, and the traversal is ended.
After the traversal is finished, whether the operations of all the front nodes of the first flow node are finished or not can be determined through the traversed state, and the following steps are carried out:
and in all the front nodes of the first flow node, if all the front nodes are in a completion state, or are in an execution-prohibited state, or a part of the front nodes are in the completion state and another part of the front nodes are in the execution-prohibited state, determining that the operations of all the front nodes of the first flow node are completed.
Optionally, if there is a pre-node that is not traversed after the states of all the pre-nodes that traverse the first flow node are finished, or the states of the traversed pre-nodes are neither a complete state nor a prohibited state, it may be directly determined that the operations of all the pre-nodes of the first flow node are not completely finished.
As in the above example, at the end of the traversal, flow node A, B, C has been traversed, and if the states of flow nodes a and C are determined to be complete, and the state of flow node B is determined to be running, then it may be determined that all operations of all predecessor nodes of first flow node E have not been completed.
If the state of the flow node B in the above example is the completion state, all the front nodes of the flow node E are the completion state, and at this time, it may be determined that the operations of all the front nodes of the first flow node E are completed.
By the technical scheme, whether the operation of all the front nodes of the first process node is finished or not is determined by traversing the states of the front nodes of the first process node, so that whether the first process node can be triggered or not is determined, accurate circulation among the process nodes in the process is ensured, and the efficiency and accuracy of process analysis are ensured.
Optionally, the message subscriber further includes a process instance, so that the process instance determines that the process parsing is ended after receiving a completion message of the end node or the abnormally terminated process node.
The flow node which is abnormally terminated is a node which is abnormal in the process of flow execution, and whether the flow node is the node which is abnormally terminated can be determined by accessing the state of the flow node.
For example, when receiving the completion message, the process instance may determine, through identification information included in the completion message, whether a node that issues the completion message is an end node, and if so, may determine that the process analysis is ended. If the node is not the end node, the state of the node issuing the completion message may be further determined, if the state is the completion state or the execution prohibition state, it indicates that the current flow is normally circulated and has not been ended, at this time, the completion message may be directly ignored, if the state is the abnormal end state, it indicates that the current flow has not been executed, but a node which is abnormally executed occurs in the intermediate process, at this time, the flow execution is abnormal, and it is also necessary to determine that the flow analysis is ended. Therefore, the flow analysis state can be determined in time, the fault tolerance of the flow analysis method is improved, the flexibility of the flow topology is improved, and the use experience of a user is further improved.
Furthermore, after the process instance determines that the process analysis is finished according to the completion message of the abnormally terminated process node, a prompt message can be output to prompt a user that the process execution is abnormal, so that the follow-up abnormal investigation is facilitated.
The present disclosure also provides a process analysis apparatus, as shown in fig. 3, the apparatus 10 includes:
