Detailed ways

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. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

The following describes the business process control method provided by the embodiments of the present application. Referring to FIG. 1, the business process control method provided by the embodiment of the present application may include the following steps:

Step S101, it is judged whether there is a first business process that changes in the database. If yes, step S102 is executed.

Wherein, the database stores at least one business process. In addition, in addition to storing each business process through the database, each business process can also be stored through Redis (remote dictionary service).

Step S102, using the changed first business process to update the existing first business process before the change in the memory.

Wherein, each business process is loaded in the memory in advance from the database mentioned in step S101.

Step S103, when the second business process needs to be executed, the second business process in the memory is loaded into the process engine.

Specifically, according to the process number of the second business process, the corresponding second business process is determined from the memory, and then the second business process is loaded into the process engine, and then the process engine executes the business process.

Wherein, each business process consists of process nodes and connection relationships between process nodes, and these process nodes are precompiled process nodes. It can be understood that the change of the business process detected in step S101 includes one or more of changes in the configuration parameters of the business process, changes in the order of some process nodes on the business process, and deletion of some process nodes. operations, the business process with these changes can be executed by the process engine without recompilation.

It can be understood that step S103 is a step independent of step S101 and step S102, and its execution is triggered by a condition. Specifically, when it is detected that the second business process needs to be executed, step S103 is executed.

The present application first determines whether there is a changed first business process by monitoring the database. Wherein, the database stores at least one business process. When it is determined that there is a changed first business process, the first business process is updated to the memory. Wherein, each business process is preloaded from the database in the memory. By loading the changed business processes from the database into the memory in quasi-real time, each business process in the memory is kept the latest version. When the second business process needs to be executed, the corresponding target business process is determined from the memory according to the process number of the second business process, and the target business process is loaded into the process engine. Among them, each business process is composed of process nodes and the connection relationship between the process nodes, the process nodes are precompiled process nodes, and the business processes composed of the process nodes can be executed by the process engine without recompilation, simplifying the process. The development and deployment process of the business process is improved, and the maintainability of the business process is enhanced.

In some embodiments of the present application, the above-mentioned process nodes are instantiated objects of classes inherited from the Activiti framework. Specifically, the process of generating these process nodes may include:

Combined with business characteristics, general nodes are abstracted, and common logic is realized through these general nodes. Different business scenarios only need to inherit the template class of common nodes, and realize business requirements through the combination of different common nodes.

Specifically, these general nodes are the various execution classes of the abstracted Activity. For example, the entry node of the business process can be inherited from StartActivity, and the node that implements the splitting can be inherited from SplitActivity.

Among them, Activity is mainly responsible for the process and logic control before and after the node, and each Activity contains a Delegate abstraction of a specific execution process. The core of the Delegate is the execute method, which is responsible for the concrete implementation of the abstract class.

In some embodiments of the present application, the above-mentioned process nodes may include: a start node, an end node, a branch node, a data node, a parallel node, an aggregation node, and a policy node.

Among them, the start node represents the execution entry of the process and is the starting point for the process to start and execute. The start node may inherit from StartActivity, which accepts the Flow Execution of the session context and triggers the execution of the Activity node of OutgoingTransition.

The end node represents the completion of the entire process.

Branch nodes are used to handle logical branches. When the business process is executed to a certain node, a fork may appear (that is, different routes are taken under different conditions). At this time, a branch node is required. The branch node has one entry, but there can be multiple exits to point to different logics. branch.

Data nodes are used to provide related data loading during process execution. For example, if the user's mobile phone number is required during the operation of the business process, a data node can be placed in front of the node, and after the data is loaded, it can be used by subsequent nodes. Among them, the data node can be inherited from JavaActivity, which is a Java task node, and its properties include a Java delegate object and a corresponding temporary input variable. When the Java task node is executed, the Java delegate object will be called first to execute the task, and then the execution of the Activity node of the Outgoing Transition is triggered after the task execution ends.

The parallel node is similar to the branch node. The biggest difference between the parallel node and the branch node is that the branch node will only choose one logical branch to execute, while the parallel node executes all the logical branches in parallel through multi-threading. The results are aggregated later, so parallel nodes must be used in conjunction with aggregation nodes. Among them, the parallel node can inherit from ForkActivity, and the parallel node supports asynchronous parallel execution of activities on each Outgoing Transition.

The aggregation node is used in conjunction with the parallel nodes mentioned above, and the results of multiple logical branches of the parallel nodes are finally aggregated to the aggregation node. Among them, the aggregation node can inherit from JoinActivity. When all the Incoming Transitions of the aggregation node are executed, the Activity of Outgoing Transition starts to be executed.

The strategy node is a relatively general rule execution strategy node defined by developers, which is equivalent to providing an execution template, which already contains basic logic operations, and developers only need to configure a few custom parameters.

In addition, process nodes can also include custom nodes, which are used for non-generic logic for special scenarios, and developers can customize as needed.

There are not many types of process nodes involved in this application, but the combination of different process nodes can facilitate the realization of complex logic, and these process nodes are all precompiled, which simplifies the development process of business processes and improves the efficiency of business process development. Development and deployment efficiency.

In some embodiments of the present application, the process of constructing the business process mentioned above may include:

S1, based on the selected node template and configuration information corresponding to the node template, generate at least one process node.

S2, a business process is generated based on the connection relationship of each process node.

Generally, a business process will contain multiple process nodes. When building a business process, you need to build process nodes first, then assign logical relationships to each process node, and finally generate a business process.

In some embodiments of the present application, the process of generating at least one process node in S1 based on the selected node template and the configuration information corresponding to the node template may include:

For each selected node template:

According to the configuration information of the node template, instantiate the node template to obtain a process node;

Wherein, the node template is a class inherited from the Activiti framework; the configuration information of the node template includes the basic attributes and field attributes of the process node to be generated, and the basic attributes include node description, class name and synchronization attribute. Field properties include the properties of the fields involved.

In some embodiments of the present application, the process of generating a business process in S2 based on the connection relationship of each process node may include:

S21: Determine the logical relationship of each process node according to the connection information of each process node input by the user.

S22: Generate a business process according to each process node and the logical relationship of each process node.

Among them, process nodes can be added by dragging through the visual operation interface. After editing the attributes of the process nodes, the logical relationship between the process nodes can be described by adding corresponding connections with flow directions for each process node.

In some embodiments of the present application, the process of determining whether there is a first business process that has changed in the database in the above step S101 may include:

Monitor Zookeeper nodes.

The Zookeeper node stores state information of each process node. When an operation of adding a business process or modifying a business process occurs in the database, the state of the newly added or modified business process will be synchronized to the Zookeeper node. By monitoring Zookeeper nodes, you can learn about changes in business processes.

The business process control system provided by the embodiments of the present application is described below. Referring to FIG. 2, the business process control system provided by the embodiment of the present application may include:

The process editor 10 is used to create, delete or edit a business process through a visual operation interface, and store the newly created or edited business process in a database;

A business process control device 20, configured to implement various steps of the business process control methods in the above embodiments;

The process engine 40 is used for executing the business process.

Wherein, through the process editor 10, the user can construct the business process by dragging and dropping the mouse through the visual operation interface. 3 and 4 illustrate a visual operation interface in the process editor 10 according to an embodiment of the present application, wherein FIG. 3 illustrates an interface for selecting a process node, and FIG. 4 illustrates an interface for editing attributes of a process node. As shown in Figure 4, the process node represents a general java processing class, and the user only needs to adjust individual parameters according to a specific scenario to realize the personalized configuration of the process node. The visual and drag-and-drop operation mode in the process editor 10 makes the creation of business processes more user-friendly and efficient, which is very convenient for rapid iteration.

The process editor 10 is used to construct the logical relationship and execution sequence between each process node, and the connection between the process nodes not only makes the operation more intuitive, but also plays a crucial role in the distribution of nodes. The connections that follow the shunt node can not only configure the shunt decision in the form of EL (Expression Language) expressions, but also adjust the order of different flow directions to customize the priority.

Each complete flowchart has a version number. If there is a major adjustment to the flowchart, you only need to copy a new version based on the original flowchart. After the adjustment, the new version can be launched at any time as needed.

Each process node involved in the business process control device 20 is universal, and only needs to modify individual node parameters. The modified flowchart is persisted to the database, and the service memory is updated synchronously to take effect in real time. It can bring great convenience to developers and significantly enhance system maintainability.

When the business process is adjusted, it will be persisted to the database first, and then updated to the memory in real time through event push and monitoring. Each time the business process control device 20 acquires the process code to be executed, it loads the latest online version process configuration from the system memory, and then the process engine 40 executes the entire process in sequence according to the sequence of each process node.
