Technical Field
The present invention relates to the field of computers, and in particular, to a method and an apparatus for processing a process engine object.
Background
The flow engine is used as a core module for state flow in flow development. The coordination work of related components is controlled by the process engine, so that the information in the business process is circulated according to a certain rule, and the automation of the business process is realized.
Conventional flow engines implement batch processing of transactions through multiple instances, such as providing countersigning and singleton signing. The countersigning means that in the transaction flow, if a node initiates an event to be handled to a plurality of people, the next node is processed only after the processing of all people is completed. The single sign means that in the transaction flow, if a to-do event is initiated for multiple people at one node, the next node is processed as long as one person finishes processing.
The traditional flow engine is controlled based on a single transaction, in an application scene, when a flow engine is needed to deploy a local area network to 10 network devices, 10 network devices are objects of the flow engine, if multiple instances of the traditional flow engine are used, due to the fact that multiple processing objects are arranged, 10 objects execute tasks at a certain node at the same time, as long as the task of any one network device is finished, the node task is finished, and other 9 network devices lose the node task in the flow engine, and subsequent node task operation cannot be carried out. Therefore, the conventional flow engine cannot implement batch processing of a plurality of objects in one node task.

and the execution module is used for acquiring the searched attribute of each object from the object attribute list of each node task information, and executing the preset operation corresponding to the current node task of the node task information on each searched object according to the searched attribute of each object.
According to the process engine object processing method, when at least one node task information sent by a process engine is received, an object corresponding to the name of the current node task of the node task information and in a state to be executed is searched in the object state list of each node task information, then the attribute of each searched object is respectively obtained, and preset operation corresponding to the current node task of the node task information is executed on each object according to the attribute of each searched object. Since the implementation objects of the preset operation of one current node task are all the objects which are searched from the object state list of the corresponding node task information, correspond to the name of the current node task and have the states to be executed, the objects searched by the current node task can be subjected to batch processing.

In a specific embodiment, after the preset operation is performed, if the object attribute of the task information of each node changes, the object attribute list needs to be updated, and the end command further includes the updated object attribute list. For example, in the node task of the lan switch, after the preset operation is performed, the lan address of the object changes, and the object attribute list needs to be updated.
S312: when a node acquisition instruction sent by the process engine according to the ending command is received, determining a next node task corresponding to each node task information; the node acquires an object state list carrying an update instruction; and updating the object state list in the flow engine by the flow engine according to each modified object state list to obtain the updated object state list.
And after receiving the ending command, the process engine ends the current node task corresponding to the node task information and judges whether the current node task exists in the next node task according to the flow chart. And when the next node task does not exist, ending the process. And when the next node task exists, the sending node acquires an instruction. The node acquisition instruction carries an object state list updated by the flow engine according to each modified object state list, namely a latest object state list.

The flow engine object processing device is connected with the flow engine through an interface for calling the flow engine. The interface of the flow engine is the encapsulated class or function. The node acquisition instruction comprises a service name of the node task information, wherein the service name comprises an interface corresponding to the current node task and a path starting from the current node task and guided by a flow line of the flow chart, so that the next node task from the current node task is determined.

The process engine receives the next node task and the object state list of the next node task to update and obtain the latest object state list. And when receiving a next node task and an object of the next node task, sending corresponding node task information to the process engine object processing device, searching an object which corresponds to the current node task name of the node task information and is in a state of waiting for execution by the process engine object processing device according to the node task information, acquiring the attribute of the searched object from the object attribute list of the node task information, and executing preset operation corresponding to the current node task of the node task information on the searched object according to the attribute, thereby realizing automatic processing of the process.
An implementation process of the process engine object processing method is described below with reference to a specific application scenario, as shown in fig. 5, which is a flowchart generated by the process engine in a specific embodiment and used for implementing local area network configuration on 100 network devices for performing switching processing on a local area network of a network device. The flow chart comprises three node tasks, which are respectively as follows: node task 1: initializing network equipment; and (3) node task 2: powering on the network equipment; and (3) node task 3: the network device switches the local area network. The state of each node task includes: pending execution, completed execution, in-execution, and failed execution. And the node task 1 is divided into two branches, if the network equipment is powered on after initial enabling, the node task 3 is executed, if the network equipment is not powered on, the node task 2 is executed to power on the network equipment, and after the network equipment is powered on, the node task 3 is executed.
Assuming that 20 network devices are powered on and the remaining 80 network devices are not powered on after the node task 1 is executed, the 20 powered-on network devices execute the node task 3 first, and the states of the node tasks of the 20 powered-on network devices are as follows: initializing the network equipment: is finished; powering on the network equipment: is finished; the network equipment switches the local area network: to be executed. In addition, if 80 network devices that are not powered on execute node task 2, the states of the node tasks of the 80 network devices are: initializing the network equipment: is finished; powering on the network equipment: waiting to be executed; the network equipment switches the local area network: to be executed.
In this embodiment, a current node task is taken as a node task 2 as an example for explanation. As shown in fig. 6, the flow engine sends node task information to the flow engine object processing apparatus, where the node task information includes a name of a current node task, an object status list, and an object attribute list. The current node task is named as: the network device is powered on. The object state list includes states of all node tasks of the network devices, and the object attribute list includes attributes of all the network devices. The attribute is specifically a network device name, an IP address of the network device, and local area network information of the network device.
After receiving the node information, the process engine object processing apparatus searches for an object whose node task name is "network device powered on" and whose state is to be executed from the object state list, that is, finds out 80 network devices that are not powered on. After finding the 80 network devices which are not powered on, the flow engine object processing device modifies the node tasks of the 80 network devices which are not powered on into the execution state of 'network device power on', and feeds back the modified object state list to the flow engine, so as to lock the 80 network settings in the 'network device power on' node tasks.
After finding 80 network devices which are not powered on, the process engine object processing device obtains the numbers (i.e. object identifiers) of the 80 network devices which are not powered on, obtains the attributes of the 80 network devices which are not powered on in the object attribute list according to the numbers, and executes the power-on operation on the 80 devices. Specifically, the attribute of the network device includes an IP address of the network device, in this embodiment, the 80 devices are controlled to be powered on by calling a third-party control program, and the third-party control program performs a power-on operation on the 80 devices according to the IP address of the device.
After the power-on operation is executed, if all the 80 network devices are powered on successfully, the state that the node task of the 80 network devices which are not powered on is 'network device power-on' is modified to be completed. And the process engine object processing device sends an end command to the process engine, wherein the end command carries the modified object state list. And the flow engine updates the object state list stored in the local according to the modified object state list. And the flow engine determines whether a next node task exists according to the flow chart, and if the next node task exists, a node acquisition instruction is sent to the flow engine object processing device, wherein the node acquisition instruction comprises a service name.
And the process engine object processing device calls the classes corresponding to the service names respectively and determines the next node task of each current node task. Specifically, the process engine records the start and end of each node task and the start and end of the next node task, and controls the flow direction through process variables and a process line. The flow engine object processing device is connected with the flow engine through an interface for calling the flow engine. The interface of the flow engine is the encapsulated class or function. The node acquisition instruction comprises a service name of the node task information, wherein the service name comprises an interface corresponding to the current node task and a path starting from the current node task and guided by a flow line of the flow chart, so that the next node task from the current node task is determined. The next node task of the network equipment which is powered on is a network equipment switching local area network, meanwhile, the state of the node task of the network equipment switching local area network, which is executed by the network equipment which is powered on and the state of the node task of the network equipment which is powered on is finished, is modified to be executed, an object state list of the next node task is obtained, and the object state list of the next node task are sent to the process engine, so that the object state list in the process engine is in the latest state. After receiving the next node task and the object state list of the next node task, the process engine sends the corresponding node task information to the process engine object processing device, and the process engine object processing device executes the node task of the network equipment switching local area network on the 80 network equipment. That is, in one node task, after all objects are executed, the next node task is executed, so that batch processing of a plurality of objects in one node task is realized.
It should be understood that, while/before/after the process engine object processing apparatus executes the node task of network device power-on 80 network devices without power-on, the process engine may further send the node task of network device switching lan to 20 network devices with power-on to the process engine object processing apparatus, and the process engine object processing apparatus respectively executes the local network switching operation on 20 network devices with power-on, thereby implementing batch processing and process automation on a plurality of node tasks, and improving processing efficiency.
