Description

Extensible scheme configuration system and method based on expression workflow

Technical Field

The invention relates to the technical field of computers, in particular to an extensible scheme configuration system and method based on expression workflow.

Background

Workflow (Workflow) is an abstract and general description of the Workflow and its business rules between its various operational steps. Workflow modeling, i.e., the logic and rules that organize how the work in a workflow is together, is expressed in a computer in an appropriate model and computed. The main problems to be solved by the workflow are: to achieve a business goal, a computer is used to automatically transfer documents, information, or tasks between multiple participants according to some predetermined rule. The workflow comprises elements such as a flow, nodes and steering rules, the traditional workflow is combined with a form engine, corresponding nodes are generated through the form engine, and form data are stored in json objects, so that the development amount is reduced. However, the requirement on the professional skills of users is high correspondingly, the dragging and generating steps of each process node are complicated, and the learning cost is high.

Disclosure of Invention

In order to solve the technical problems, the invention provides an extensible scheme configuration system based on an expression workflow, which solves the problem that each node cannot dynamically configure conventional variables when the workflow function is realized.

The technical scheme of the invention is as follows:

the present invention provides an extensible scheme configuration system based on expression workflows,

Wherein the content of the first and second substances,

1) each scheme corresponds to a json object, configurable variables corresponding to workflow id and each node in the workflow and corresponding to the workflow are stored in the json in the form of key and value;

2) the method comprises the steps that when a json object corresponding to a scheme is analyzed in a background, data filling is carried out through keys in json according to dictionary configuration, and a form data format is formed and returned to a front end;

3) and the front end generates a scheme configuration page according to the form data transmitted back by the background.

Further, in the above-mentioned case,

any node sets its key to key1, and its corresponding value is a new json object, storing configurable variables.

In a still further aspect of the present invention,

the dictionary configuration is to fill keys in json objects.

Setting any key in the scheme table as period, and configuring corresponding data in the dictionary table as period (key) -node-time limit review (title) -text (type); review (key) -variable-review (title) -input (type).

The invention also provides an extensible scheme configuration method based on the expression workflow, which comprises the steps of establishing a scheme table on the basis of the function of the workflow, configuring a scheme corresponding to each flow, and recording personalized variables in the scheme; if the personalized requirements do not exist, reading default settings;

and setting a dictionary table, performing extended analysis on the key of the scheme in the scheme table, and finally generating the data of the form for display.

Further, in the above-mentioned case,

and separating the scheme configuration of the node from the workflow based on the expression workflow.

Each node in the workflow is preset, and the turning rule among the nodes is realized through a custom formula.

Further, in the above-mentioned case,

the storage content in the scheme table is stored in the form of key and value;

the time limit review node can set the key to be period, the corresponding value of the time limit review node is a new json object, and configurable variables are stored.

In a still further aspect of the present invention,

the dictionary configuration is to fill keys in json objects.

Setting key in the scheme table as period, and configuring the inside of the dictionary table as period (key) -node-time limit review (title) -text (type); review (key) -variable-review (title) -input (type).

The invention decouples the workflow engine and the form engine in the traditional development. The personalized configuration of the nodes and the turning rules of the node circulation of the whole process are not interfered with each other. Personalized configuration of the nodes is not performed, i.e. default configuration is taken.

The scheme table is associated with the processes, and realizes the personalized requirements of each process.

The dictionary table is associated with keys inside the scheme table and is generic.

The invention has the advantages that

An extensible configuration scheme is provided for a workflow engine which is realized by a simplified workflow representation and calculation method based on expressions.

The workload caused by the increase of new nodes or new variables is reduced, and the configuration is only needed in the dictionary table, so that the node can be provided for operators to use.

The nodes in the workflow can be additionally arranged in a matched mode, the universality of the nodes is achieved, if the nodes are not configured, default configuration is carried out, and the usability of the system is improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.

The present invention provides an expression-based workflow implementation, but is decoupled therefrom. On the basis of the function of the workflow, a scheme table is created, a scheme corresponding to each process is configured for each process, and personalized variables are recorded in the scheme. If the personalized requirements do not exist, the default setting is read, and the process dragging and generating operation is simplified. In order to better perform the operations of adding, deleting, modifying and checking the scheme table on the page, a dictionary table is set, the keys of the schemes in the scheme table are subjected to expansion analysis, and finally data similar to the form is generated to be displayed at the front end.

1. Scheme table

And formulating a scheme table, wherein each scheme corresponds to a json object, and configurable variables corresponding to workflow id and each node in the workflow and corresponding to the schemes are stored in the json in the form of key and value. Such as: the project period review node can set its key as period, its corresponding value is a new json object, and stores configurable variables, such as review number (review), review role limit (role), and the like.

2. Dictionary table

And when the json object corresponding to the scheme is analyzed in the background, data filling is carried out through keys in json according to dictionary configuration, and a form-like data format is formed and returned to the front end.

The dictionary configuration is mainly to fill keys in json objects. For example, period exemplified in the technical solution "a, a solution table", a dictionary table may be configured as period (key) -node (node) -time limit review (title) -text (type); review (key) -variable (variable) -input (type)

3. Front end

And the front end generates a scheme configuration page according to the form data transmitted back by the background.

The invention relates to a method for performing extensible configuration on nodes in a workflow. The user only needs to know the implementation function of each node, and only needs to care about the steering rule to realize the process conversion between the nodes, and the additional configuration can be realized in a scheme configuration system matched with the nodes.

The above description is only a preferred embodiment of the present invention, and is only used to illustrate the technical solutions of the present invention, and not to limit the protection scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
