[0080] REFERENCE Figure 1 It is a system architecture diagram applicable to the embodiments of the present application, and the system at least includes a flow engine device 101 and a terminal device 102.
[0081] The process engine device 101 and the terminal device 102 can be a server cluster composed of multiple physical servers or a distributed system, and can also be a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms. The process engine device 101 and the terminal device 102 can be directly or indirectly connected through wired or wireless communication, which is not limited in the present application. The process engine device 101 and the terminal device 102 interact to implement the process of the signal processing method. It should be noted that the acquisition, storage, use, processing, etc. of data by the process engine device in the technical solution of the present application comply with the relevant provisions of national laws and regulations.
[0082] Based on Figure 1 The system architecture diagram shown in the present application embodiment provides a process of a signal processing method, as shown in Figure 2A The process of the method is executed by a computer device, which can be Figure 1 The process engine device 101 shown in the present application embodiment includes the following steps:
[0083] Step 201, receiving the to-be-processed signal sent by the terminal device, and analyzing the to-be-processed signal to obtain process information.
[0084] Specifically, in the stage of signal preparation and signal sending in the terminal device, the terminal device can configure the signal according to the demand. The terminal device first receives the signal request to be sent, then acquires the required process information according to the information in the signal request to prepare for sending the signal, generates a new signal object, and then sends the signal.
[0085] The process information includes one or more of the following: process instance, target signal node, signal task, and process template.
[0086] In some embodiments, the to-be-processed signal sent by the receiving terminal device is in a synchronous mode or an asynchronous mode.
[0087] The signal node in the present application supports two working modes: synchronous mode and asynchronous mode. The synchronous mode is to call the signal service application program interface (API) of the process engine device, and the asynchronous mode is the signal asynchronous thread mode.
[0088] The synchronous mode is that the terminal device and the process engine device are in the same thread and follow the same thing principle. It is shown that the terminal device sends a signal by directly calling the API of the signal service of the process engine device and waits for the return result of the signal processing of the process engine device. The process engine device returns a notification result when it runs to a subsequent manual node or signal node, i.e., stops at a node of a non-automatic type. In the synchronous mode, when an exception occurs in the signal receiving or signal processing process, the application and the process engine device both perform data rollback, which is equivalent to not sending and receiving the signal this time.
[0089] The asynchronous mode is that the terminal device and the process engine device are in different threads and follow the different thing principle. The terminal device also calls the API of the signal service of the process engine device, but the terminal device does not need to wait and can continue other operations. The process engine device uses a new thread in the signal asynchronous thread service to receive the signal and perform subsequent processing operations, which is the same as in the synchronous mode. In the asynchronous mode, if an exception occurs in the process engine device, the process engine device only performs rollback according to the current transaction, and the terminal device is in another transaction and does not perform rollback.
[0090] Whether the terminal device sends the to-be-processed signal in the synchronous mode or the asynchronous mode depends on whether the asynchronous notification keyword "asyn_notify" is contained in the context information in the signal. If the asynchronous notification keyword "asyn_notify" is contained and its value is true, it is the asynchronous mode, otherwise it is the synchronous mode.
[0091] In step 202, if the process information corresponding to the process instance, the target signal node and the signal task exist in the database, the signal task is submitted.
[0092] Specifically, when the process engine device receives the to-be-processed signal sent by the terminal device, it first searches the database to find whether the process information corresponding to the to-be-processed signal exists, and if so, the task of the to-be-processed signal is submitted.
[0093] The signal receiving and signal processing stage is located in the process engine device, as shown in FIG. 2, the process engine device receives a signal, parses the signal, obtains the process information in the signal, and queries whether there is a process instance, a target signal node and a signal task that meet the conditions in the database according to the process information, so as to determine whether the signal is valid. If so, the signal task is submitted, so that the process engine device continues to flow down, at the same time, the signal information is recorded, and the signal state is modified to be used; if not, the signal state is modified to be invalid, and the task submission operation is not performed. Figure 2B
[0094] Step 203, according to the process instance, the process is transferred between multiple process nodes until the process is transferred to the target signal node, the signal task is processed, and the processing result is obtained.
[0095] In some embodiments, the plurality of process nodes of the process instance includes a plurality of signal nodes, and the plurality of signal nodes are located on a plurality of parallel process branches.
[0096] Specifically, multiple signal nodes are allowed to be configured in one process instance, that is, there are multiple signal nodes. In this case, the diversity and complexity of the use of terminal devices are increased. The use of multiple signal nodes has certain prerequisites and requirements. Generally, only multiple signal nodes are allowed to be configured in the case of multiple process branches, and the use order of the signal nodes is required to be aggregated or artificially controlled to ensure the uniqueness of the overall process running.
[0097] Before the signal task is processed and the processing result is obtained, as shown in Figure 3 , the following steps are further included:
[0098] Step 301, when the task state of the preceding node of the target signal node is detected to be a completed state, the task state of the target signal node is set to a new state.
[0099] Specifically, in the running process of the process engine device, many nodes will be passed through. Only after the newly created task is submitted and completed, the task can reach the subsequent node and create a new task accordingly. As shown in Figure 4 , the solid line represents the execution, and the dashed line represents the non-execution. When the task state of the preceding node is in the completed state, the process engine device creates a new task for the target signal node. At this time, the task state of the target signal node is in the new state, that is, the target signal node is in the state of waiting for receiving the signal, and the state of the subsequent node is not arrived.
[0100] In some embodiments, if an exception occurs when the task state of the target signal node is set to the new state, the process is rolled back to the preceding node.
[0101] Specifically, when an exception occurs when the task state of the target signal node is set to the new state, the process engine device automatically rolls back forward until a manual node or a signal node is found. If neither of the nodes is found, the entire process instance is rolled back.
[0102] Step 302, when the process is transferred to the target signal node, the task state of the target signal node is set to a submitted state.
[0103] Specifically, after the target signal node receives the to-be-processed signal and judges that the to-be-processed signal is valid, the process engine device processes the signal task, as shown inFigure 5 At this time, the task state of the front node is completed, the task state of the target signal node is submitted, and the task state of the subsequent node is still in the not arrived state.
[0104] In some embodiments, if an exception occurs when the task state of the target signal node is set to the submitted state, the step of setting the task state of the target signal node to the new state is rolled back.
[0105] Specifically, when an exception occurs when the task state of the target signal node is set to the submitted state, the process engine device also performs data rollback, the operations and data in the task submission process are invalid, and the task returns to the state of the previous signal task new.
[0106] In step 303, the signal task is processed, and after obtaining the processing result, the task state of the target signal node is set to the completed state.
[0107] Specifically, when the task state of the target signal node is completed, the post node receives the target signal, and the process engine device sets the task state of the post node to the new state, as shown in Figure 6 .
[0108] In some embodiments, if an exception occurs when the task state of the target signal node is set to the completed state, and the node task of the post node of the target signal node has been newly created, the rollback operation is not performed.
[0109] Specifically, the process has flowed to the post human node or signal node, at this time, the abnormal process will not be rolled back to the current signal node, but will be rolled back to the post human node or signal node.
[0110] If an exception occurs when the task state of the target signal node is set to the completed state, and the node task of the post node of the target signal node has not been newly created, the step of setting the task state of the target signal node to the new state is rolled back.
[0111] In the embodiments of the present application, by setting the task state of the signal node to different states, the state of the current signal node can be clearly observed, and different measures can be taken according to different states, thereby improving the accuracy of processing.
[0112] In some embodiments, if the process instance corresponding to the process information does not exist in the database, it is determined that the signal to be processed is an invalid signal.
[0113] Specifically, according to the flow information in the to-be-processed signal, only the corresponding flow definition information and target signal node information can be found, and no flow instance and signal task exist. In this case, although the to-be-processed signal exists, no effective flow instance information exists, and the to-be-processed signal is referred to as an invalid signal. For this case, the to-be-processed signal will not be stored in the database.
[0114] Of course, if the flow instance corresponding to the flow information, the target signal node and the signal task do not exist in the database, the to-be-processed signal is also an invalid signal. For this case, the to-be-processed signal will not be stored in the database.
[0115] In some embodiments, if the flow instance corresponding to the flow information and the target signal node exist in the database, the flow is transferred between the plurality of flow nodes according to the flow instance until the flow is transferred to the target signal node. Then, the signal task is newly created and submitted. The signal task is processed to obtain a processing result.
[0116] Specifically, the flow instance corresponding to the to-be-processed signal exists in the database, but the to-be-processed signal has not arrived at the target signal node. In this case, the corresponding target signal node and flow instance information can be found according to the flow information in the to-be-processed signal, but no signal task exists. In this case, the to-be-processed signal is an effective signal, the state of the to-be-processed signal is recorded as "unused" and stored in the database. When the flow runs to the target signal node, the target signal node of the flow instance is searched in the database. When it is found that the corresponding to-be-processed signal exists and the state is "unused", the flow engine device directly submits the corresponding signal task for processing, and modifies the state of the to-be-processed signal to "used". Before the flow instance is started and runs to the target signal node, the user application end can repeatedly send signals. These signals will be used only once after the signal task is created, and the state thereof will be modified to "used".
[0117] In some embodiments, if the flow instance corresponding to the flow information, the target signal node and the signal task exist in the database, and the task state of the signal task is completed, it is determined that the to-be-processed signal is an invalid signal.
[0118] Specifically, the flow instance corresponding to the to-be-processed signal, the target signal node and the signal task can be found according to the flow information in the to-be-processed signal in the database, but the state of the signal task is completed. This signal is also an invalid signal, and for this case, the signal will not be stored in the database.
