Description

Technical Field

[0001] The embodiments of the present invention relate to automatic programming technology, and more particularly to a rule engine configuration method, apparatus, device and storage medium. Background Art

[0002] A rule engine, also known as a business rule management system (BRMS), is an application component that separates business decision-making statements from application code and embeds them into the program.

[0003] Rule engines use predefined semantic modules to write business decisions, known as business rules, which are then configured and managed by users or developers as needed. Large enterprises, especially those in the banking and financial sectors, have a wide variety of complex business rules, making configuration cumbersome. Existing rule engines typically use Java-based rule engines, such as Drools. Drools is a heavyweight rule engine component with low execution efficiency and lacks support for dynamic configuration.

[0004] In real-world applications, projects often change, so the rule engine needs to be configured based on business needs. However, due to the tight coupling between business rules and the application system's Java code in existing technologies, pre-configured business rules are difficult to view and maintain in real time, resulting in difficult project maintenance and slow response times. Summary of the Invention

[0005] Embodiments of the present invention provide a rule engine configuration method, apparatus, device, and storage medium to facilitate configuration and management of business rules in a rule engine.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0026] Example 1

[0027] Figure 1 This is a flowchart of a rule engine configuration method provided in the first embodiment of the present invention. This embodiment is applicable to situations where an enterprise configures a rule engine based on business needs, such as establishing a rule engine for a banking or financial enterprise. The method can be performed by a rule engine configuration device, which can be implemented by hardware and / or software and can generally be integrated into a rule engine configuration device, such as a server. The method specifically includes:

[0028] Step 110: Publish the preset rule engine public file package to the preset project repository;

[0029] The preset rule engine public file package can be a jar package, which can include a preset database rule table for recording user-configured business rules. The rule engine management platform can publish the preset rule engine public file package to a preset project repository, such as a Maven repository. The Maven repository helps us manage artifacts and is where all jar files are stored.

[0030] Optionally, before publishing the preset rule engine public file package to the preset project warehouse, the method further includes: compiling and generating the preset rule engine public file package; wherein the preset rule engine public file package is a jar package.

[0031] Step 120: In response to the rule engine file package pulling operation, pull the corresponding preset rule engine public file package from the preset project warehouse;

[0032] Among them, users who need to configure the rule engine can request the rule engine management platform to pull the preset rule engine public file package from the preset project warehouse.

[0033] Step 130: In response to the rule configuration operation, the user-configured rules are written into the preset database rule table in the preset rule engine public file package to generate a user-configured rule engine.

[0034] Users generate different rules based on the business needs of their enterprise systems and their business-related data. After obtaining the preset rule engine public file package, they write their own business rules into the preset database rule table within the preset rule engine public file package, thereby generating a rule engine configured by the user based on their business needs. The user-configured rule engine can include at least two rules, which can be modified and deleted, and of course, new rules can also be added to the preset database rule table.

[0035] The technical solution of this embodiment distributes the preset rule engine public file package to the preset project warehouse, writes business rules according to the user's configuration operations, and generates a rule engine, thereby solving the problems of difficult project maintenance and slow response speed caused by the inconvenience of real-time viewing and maintenance of business rules, and achieving the effect of convenient configuration and management of business rules in the rule engine and rapid response to project changes.

[0036] Example 2

[0037] Figure 2 This is a flowchart of a rule engine configuration method provided in Example 2 of the present invention. This embodiment further refines the above technical solution. Specifically, the user-configured rules may include rule conditions, rule actions, and priorities. The method specifically includes:

[0038] Step 210: Publish the preset rule engine public file package to the preset project repository;

[0039] Step 220: In response to the rule engine file package pulling operation, pull the corresponding preset rule engine public file package from the preset project warehouse;

[0040] Step 230: In response to the rule configuration operation, the user-configured rules are written into the preset database rule table in the preset rule engine public file package to generate a user-configured rule engine.

[0041] Step 240: In response to the rule adding operation, add at least one rule to the rule engine;

[0042] Step 250: In response to the rule modification operation, modify at least one of the rule condition, rule action, and priority of the rule engine accordingly;

[0043] Step 260: In response to the rule deletion operation, delete the current rules in the rule engine.

[0044] When users configure rules, they must also configure their priority. Since a user-configured rule engine can include at least two rules, a corresponding priority is set for each rule. After generating the rule engine, the rule management system provides online maintenance services, including performing at least one of the following operations on the rules in the rule engine: adding, modifying, and deleting. In other words, steps 240, 250, and 260 are executed based on the user's requested operation. For adding new rules, the rule conditions, rule actions, and priority levels must be set. For deleting rules, either a single rule or a group of rules can be deleted. Optionally, at least one rule set is configured in the pre-set database rule table, and a rule set can contain at least one rule. If a rule set contains multiple rules, the rule set identification number can be searched and the searched rule set can be deleted. For modifying rules, the rules within the rule set can be modified in batches based on the rule set identification number. Individual rules within a rule set can also be modified based on the rule identification number.

[0045] The technical solution of this embodiment can manage the rules in the preset database rule table, facilitate the review of the rules recorded therein, and also facilitate the addition, modification and deletion of rules in the rule engine, so as to conveniently adjust the rule engine to adapt to changes in the project.

[0046] Example 3

[0047] Figure 3 This is a flowchart of a rule engine configuration method provided in the third embodiment of the present invention. This embodiment further refines the above technical solution. Specifically, in response to the rule configuration operation, the user-configured rules are written into the preset database rule table in the preset rule engine public file package to generate a user-configured rule engine. The method specifically includes:

[0048] Step 310: Publish the preset rule engine public file package to the preset project repository;

[0049] Step 320: In response to the rule engine file package pulling operation, pull the corresponding preset rule engine public file package from the preset project warehouse;

[0050] Step 330: In response to the rule configuration operation, configure at least one rule set in the preset database rule table, and configure at least one rule in the rule set;

[0051] The preset database rule table can use the rule set identification number, i.e. ruleset_id, as the primary key. Multiple rules can be set under a rule set. Each rule corresponds to a rule identification number, i.e. rule_id. Each rule has its own rule condition, rule action, and priority.

[0052] Step 340: Set a set priority for the rule set and set a rule priority for the rule;

[0053] Once configured in the database, the rule engine reads the rule conditions configured in the preset database rule table, parses the rule execution conditions using MVEL (MVFLEX Expression Language), and executes the corresponding rule actions. Priorities are divided into rule set priority (rulesetPriority) and rule priority (rulePriority). The rule engine first executes the rule set actions based on the rule set priority. Within the same rule set, the actions of each rule are executed based on the rule priority.

[0054] Step 350: Configure the rule condition and the rule action for each rule, and set the working status of each rule.

[0055] Among them, the rule status rule_status of the rule can also be set in the preset database rule table, that is, whether the rule is enabled in the rule engine. In this way, rules that are not needed temporarily can be set to disabled, and the rules will not be directly deleted from the rule engine, which is convenient for flexible adjustment of the rules enabled in the rule engine according to business needs.

[0056] Optionally, after configuring at least one rule in the rule set, the method further includes:

[0057] A rule description is set for each rule. In the preset database rule table, a rule description rule_dsc is also set. With the rule description, the function of the rule can be intuitively understood, which is convenient for subsequent development and management.

[0058] Optionally, the preset database rule table includes an Oracle database rule table and an HBase database rule table. That is, when the user configures the rule engine, it supports writing rules into the Oracle rule table or supports writing rules into the HBase rule table.

[0059] Optionally, the rule engine may support multiple rules and multiple rule actions, including: ElasticsearchAction, HBaseAction, and InvokeAction.

[0060] Among them, for ElasticsearchAction, Elasticsearch is a real-time distributed search and analysis engine. The rule engine can provide Elasticsearch retrieval, providing rule engine users with more action execution methods. For HBaseAction, HBase is a distributed, column-oriented open source NoSQL database. This rule engine execution action provides query, add, modify, and delete functions based on HBase. For InvokeAction, InvokeAction is an execution action class called based on the Java reflection mechanism. The rule engine user enters the class name, method name, and parameters required by the method to be reflected and invoked. Through InvokeAction, the method under the class can be executed to implement the action execution.

[0061] The technical solution provided by this embodiment can set up multiple rule sets in a preset database rule table for systems with multiple and complex rules. Each rule set contains multiple rules, and actions are executed according to different conditions and priorities. Moreover, it can adapt to the caller's needs for multiple invocation methods. The rule engine supports multiple reading and writing requirements such as HBase and Elasticsearch, and also supports reflective invocation of Invoke. The rules configured in this embodiment support more complex and diverse rule logic, are more flexible and efficient, and meet the complex and changing business needs of the caller.
