[0043] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. Example

[0044] The embodiment of the present invention provides a method for establishing a BPMN process engine adaptation, such as Figure 1 As shown, the following steps are included:

[0045] Step S1: Obtain the process engine file defined by JSON structured data in the engine file designer.

[0046] In the embodiment of the present invention, the engine file designer interprets the JSON structured process data through a preset template engine to generate a process engine file that meets the preset parsing requirements. This is only an example and is not limited to this. In actual applications, the corresponding template engine and parsing requirements are selected according to actual needs.

[0047] In the embodiment of the present invention, the JSON process engine file structure uses the JSON data structure to construct respective data element attributes and extended attributes to generate a process engine file of the JSON structure.

[0048] In an embodiment of the present invention, the JSON structured process engine file designer is essentially different from the traditional BPMN.js process designer. The engine file designer uses a template engine to interpret process data in a JSON structure, and can quickly generate engine files that meet parsing requirements. The JSON structured process engine file designer does not have any difficult-to-understand technical terms, and completely defines the various nodes and node attributes of the business process diagram based on its own business scenarios, such as financial approval business, personnel performance business, etc. At the same time, custom plug-ins for specific scenarios can be customized to meet different business scenarios, allowing business personnel to focus more on the business itself.

[0049] In a specific embodiment, the designer is mainly used to quickly build a process design tool in JSON format. It uses the H5 drawing board technology to drag and drop, does not rely on backend service support, and can be run independently or quickly integrated into an existing business system as a plug-in file. Based on the design ideas of componentization, plug-inization and templateization, built-in commonly used business components and plug-ins can quickly adapt to common business scenarios and achieve the goal of out-of-the-box use.

[0050] In a specific embodiment, the overall architecture of the JSON process designer is as follows: Figure 2 As shown, the business process is designed with the help of the JSON process designer, and finally displayed and used with specific JSON structured data.

[0051] Among them, the JSON data structure is divided into three parts: the root node data structure, such as Figure 3 As shown, as the starting node of the entire process, it contains the basic information of the process data: unique identification, name, description, grouping, and custom expansion tree. This is only an example and is not limited to this. In actual applications, the basic information of the response is selected according to actual needs.

[0052] Leaf node process data structure, such as Figure 4 As shown in the figure, the business logic of the entire process, form attributes, branch nodes, and the relationship between parent and child nodes are described. Each leaf node has its own node type, unique identifier, name, parent node identifier, and next node identifier.

[0053] Custom node data structure, such as Figure 5 As shown, it is used to enhance the scalability of the business process structure and adapt to various business scenarios.

[0054] Step S2: Through the JSON structured process engine file configurator, based on the preset mapping rules, the association between the process engine file defined by the JSON structured data and the general process engine file of the process engine processor is completed.

[0055] In the embodiment of the present invention, the JSON structured process engine file configurator is a bridge between the process engine file defined by the JSON structured data and the general process engine file of the process engine processor. The configurator parses the mapping rules of the metadata in the JSON structured process file and the specific elements such as the start element, service element, and sequence element in the process processor, and associates the JSON structured process engine file with the general process engine file that the process processor can parse.

[0056] In the embodiment of the present invention, the preset mapping rules include: parsing the metadata in the process engine file defined by the JSON structured data through the JSON structured process engine file configurator, and / or the mapping rules of specific elements in the process processor. The specific elements include: start elements, service elements, and sequence elements, which are only examples and are not limited to this. In actual applications, the corresponding specific elements are selected according to actual needs.

[0057] In an embodiment of the present invention, a JSON process file rule configurator solidifies process elements according to the BPMN2.0 protocol specification, and establishes a corresponding relationship between attributes of each node in a JSON engine file through a visual configuration interface.

[0058] In the embodiment of the present invention, Figure 6 As shown, the business process diagram is designed through the process designer, and specific structured data is generated in the form of JSON structure data. The JSON structured data is mapped to the process elements of the BPMN protocol standard through the visual configuration interface to achieve matching with the process engine processor.

[0059] Step S3: Generate a process object by using a JSON structured process engine file parser based on the process engine file defined by the associated JSON structured data and a parsing algorithm with preset rules.

[0060] In an embodiment of the present invention, the parsing algorithm of the preset rule corresponds to the preset mapping rule. For example, when the preset protocol standard is the BPMN2.0 protocol standard, the JSON structured data is mapped into the process elements of the BPMN2.0 protocol standard by the configurator, and the file parser gradually generates flow object data (FlowObjects), connection object data (Connecting Objects), gateway object data (Gateway Objects) and data objects (Data Objects) according to the configuration rules.

[0061] In an embodiment of the present invention, the rule parser dynamically parses the defined rules, creates a process engine processor that can recognize the parsed event objects, task objects and sequence flow objects, and generates BPMN model objects in accordance with the BPMN2.0 protocol specification, relying on ORM technology to directly persist the element objects involved in the business process diagram.

[0062] Step S4: Through the JSON structured process engine file validator, when the process object meets the preset protocol standard, the generated process object is stored in the respective database tables of the process engine processor according to the ORM technology.

[0063] In the embodiment of the present invention, each generated process object is verified according to the standard BPMN2.0 protocol elements, and error information and prompt information are given for objects and attributes that do not meet the protocol standards. The form of the error information and prompt information is not limited here, and they are obtained accordingly according to actual needs. After verification, the generated process object data is directly persisted to the database table of each process engine processor based on ORM technology.

[0064] In an embodiment of the present invention, a JSON structured process engine file validator is used. The main purpose of the validator is to check whether the process engine object generated by the JSON engine file meets the BPMN2.0 protocol standard, and to provide prompts and modification plans for object elements that do not meet the standard, so as to facilitate the adjustment of mapping rules.

[0065] The method for establishing the BPMN process engine adaptation provided in the embodiment of the present invention, wherein the present application reduces the complexity and entry threshold of process design through the JOSNized process designer, so that everyone can become a business process designer, allowing business personnel to focus more on their actual business processes. The complexity and high coupling of the business system docking with the BPMN system are reduced through the rule matcher, process parser and process object persistence, and the integration cost between the business system and the BPMN system is reduced. Example

[0066] The embodiment of the present invention provides a system for establishing a BPMN process engine adaptation, such as Figure 7 As shown, including:

[0067] The JSON process design module 1 is used to obtain the process engine file defined by the JSON structured data in the engine file designer; this module executes the method described in step S1 in Example 1, which will not be repeated here.

[0068] JSON process file configuration module 2 is used for JSON structured process engine file configurator, which completes the association between the process engine file defined by JSON structured data and the general process engine file of the process engine processor through preset mapping rules; this module executes the method described in step S2 in Example 1, which will not be repeated here.

[0069] The JSON process file parsing module 3 is used to generate a process object through a JSON structured process engine file parser based on the process engine file defined by the associated JSON structured data, using a parsing algorithm with preset rules; this module executes the method described in step S3 of Example 1, which will not be repeated here.

[0070] The JSON process file verification module 4 is used to use the JSON structured process engine file validator. When the process object meets the preset protocol standard, the generated process object is stored in the respective database tables of the process engine processor according to the ORM technology; this module executes the method described in step S4 in Example 1, which will not be repeated here.

Through the JOSNized process designer, the complexity and entry threshold of process design are reduced, so that everyone can become a business process designer, allowing business personnel to focus more on their actual business processes. Through the configurator, parser and validator, the process object is made persistent, which reduces the complexity and high coupling of the business system docking with the BPMN system.
