[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0029] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.
[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the present invention described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0031] In this embodiment, a method for dynamically configuring business rules based on a rule engine is provided. Figure 1 is a flow chart of a method for dynamically configuring business rules based on a rule engine according to an embodiment of the present invention. Figure 1 As shown, including: S100, receiving a business rule dynamic configuration request, where the business rule dynamic configuration request at least includes a business rule configuration target; In the embodiment of the present invention, the business rule dynamic configuration request at least includes a business rule configuration target, and dynamic parsing can be achieved based on the business rule configuration target.
[0032] S200, dynamically parse the request according to the business rule dynamic configuration to obtain a dynamic parsing result; In the embodiment of the present invention, the dynamic parsing can be specifically divided into two steps: first, converting the character string into a word sequence, and second, parsing the word sequence into a syntax tree. Based on the dynamic parsing, a dynamic parsing result can be obtained.
[0033] S300, configuring and updating current business rules according to the dynamic analysis result; The current business rules can be updated according to the above dynamic analysis results.
[0034] S400: Output the updated business rules.
[0035] In the embodiment of the present invention, the rule engine is specifically developed from the reasoning engine, which is a component embedded in the application program, which realizes the separation of business decisions from the application program code and uses predefined semantic modules to write business decisions. It accepts data input, interprets business rules, and makes business decisions based on business rules. From the perspective of business use, the rule engine can well help business personnel to make new business rules take effect directly by adjusting the configuration without recoding, compiling, and deploying the application.
[0036] like Figure 2 It explains the difference between traditional coding methods and rule engines. From this, we can clearly see that the application of rule engine technology can greatly improve related businesses.
[0037] From a technical point of view, the rule engine is responsible for obtaining outputs based on the input of the caller and the configured rules. For example, a very simple example is user registration service. When the user is under 18 years old, we return an error message, otherwise it indicates that the registration is successful. Here the input is user information, the rule is age judgment, and the output is various results of the registration service. The general process is as follows: Figure 3 shown.
[0038] In the above business, the main job of the rule engine is to provide a dynamically configurable way to modify the calculation logic of the application without recoding to achieve the purpose of business change. Or for the user registration business, if the entry age of our application is lowered in the future, and users over 16 years old can register, then we only need to modify the above Figure 3 The computing configuration part can make new business rules take effect in real time, greatly improve business efficiency and seize market opportunities.
[0039] Therefore, the business rule dynamic configuration method based on the rule engine provided by the present invention realizes dynamic parsing through the dynamic configuration request of the business rules, and then realizes the configuration update of the business rules, solves the technical problems of requiring professional programming capabilities and a lot of development time in the traditional software development model, thereby reducing the development cycle and maintenance costs and avoiding waste of resources.
[0040] Specifically, in the embodiment of the present invention, the dynamically configured computing logic part, namely the rule engine, is a syntax parsing technology based on technical personnel and with the goal of being efficient, flexible and fully functional.
[0041] In the embodiment of the present invention, the request is dynamically parsed according to the business rule dynamic configuration to obtain a dynamic parsing result, such as Figure 4 As shown, including: S210, extracting the business rule configuration target in the business rule dynamic configuration request; S220, converting the business rule configuration target into a business rule configuration character string; Dynamic parsing is responsible for calculating the grammatical meaning of a string of input characters, which may be any code, and executing these grammatical meanings, such as Figure 5 As shown in the figure, dynamic parsing is divided into two stages: converting a string into a word sequence and parsing the word sequence into a syntax tree. The words here are the words designed based on the basic Java syntax we just talked about. For example, integer words can be represented by regular expressions: "[-+]{0,1}[0-9]+".
[0042] S230, converting the business rule configuration string into a word sequence; According to the input string, it starts parsing from the first character one by one. After each parsing, a word is formed and put into the word sequence until the last word. During this parsing process, if a lexical error is found, an exception is thrown. For example, the function noun method requires that the function must start with a letter. If the function name entered by the user is like this: 123now(), an exception will be thrown directly: Illegal word: '123now()'. The process of converting a string into a word sequence is as follows: Figure 6shown.
[0043] Specifically, Figure 7 As shown, the business rule configuration string is converted into a word sequence, including: S231, parsing the business rule configuration strings one by one to obtain a word corresponding to each business rule configuration string; It should be understood that when parsing the business rule configuration character strings one by one, they can be parsed one by one in an order from the outside to the inside to obtain the corresponding words after parsing.
[0044] Specifically, the business rule configuration strings are parsed one by one to obtain words corresponding to each business rule configuration string, including: Parsing the business rule configuration string one by one in order from the outside to the inside, wherein the order from the outside to the inside includes: external variable declaration, external variable name, internal attribute information, internal variable name, operation rule and operand; The parsed words are formed into word sequences.
[0045] S232. Place the words corresponding to all business rule configuration strings in a parsing order to form a word sequence.
[0046] It should be noted that when the business rule configuration character strings are parsed one by one, lexical error detection is performed on the parsed words; when a lexical error is found, an abnormal signal is generated.
[0047] S240: Parse the word sequence into a syntax tree to obtain a dynamic parsing result.
[0048] Specifically, parsing the word sequence into a syntax tree includes: The word sequence is parsed in the order of the character string parsing configured by the business rule to form a syntax tree, wherein the levels of the syntax tree are, from high to low, functions, variables, and operands.
[0049] It should be understood that after the lexical analysis stage, a sequence of words is obtained, and now it is time to convert it into a syntax tree. When defining words at the beginning, you also need to define syntax such as calculation syntax: exp cal exp. The calculation expression represented by this syntax means two expressions with a calculator in between to form a calculation expression. Here, exp stands for expression. Expressions can be of many types. Variables are also expressions, numbers are also expressions, functions are also expressions, and calculation expressions are also a representation, that is, the value of any type of expression can be used for calculation. In order to reflect the hierarchy of the syntax tree, this string is used for demonstration: add(user.age, 1). The syntax tree that the string is finally parsed into is as follows: Figure 8 shown.
[0050] In an embodiment of the present invention, parsing the word sequence into a syntax tree further includes: Traversing each node of the syntax tree in descending order of the hierarchy of the syntax tree; When traversing to the current node, determine whether the corresponding calculation needs to be performed; If the corresponding calculation needs to be performed at the current node, the calculation corresponding to the node is performed according to the calculation rules; When the traversal of each node of the syntax tree is completed, each node completes the corresponding calculation at the same time.
[0051] It should be understood that from the syntax tree, we can see that the add function name is at a higher level, while the user variable, age variable, and 1 number are at a lower level. Usually, when calculating the syntax tree, each node is traversed from left to right and from top to bottom, and when traversing the node, it is determined whether the corresponding calculation needs to be performed. Finally, when all nodes are traversed, the calculation corresponding to the syntax has been completed. The specific traversal process is as follows Fig. 9 shown.
[0052] In summary, the dynamic configuration method of business rules based on the rule engine provided by the present invention enables business personnel to make new business logic effective by directly modifying the configuration without having to go through the traditional coding process again when encountering changes in business logic; business personnel can write any syntax that meets the specifications according to the pre-defined syntax specifications to make new business rules effective. The rule engine can automatically identify incorrect configurations and return corresponding prompts to the user to help the user modify their configuration. The rule engine can identify each atomic configuration and execute the corresponding calculation logic according to the configuration rules; the rule engine can identify nested configurations, and layer the nesting, execute the calculations corresponding to each configuration from the inside out, and cache the results of each calculation for subsequent configurations.
[0053] Therefore, based on the above functions, applications can be quickly built, and accumulation and precipitation can be achieved to achieve rapid delivery of industrialized software. The precipitation of application-level and business-level templates improves resource reuse and reduces development costs. The business rule dynamic configuration method based on the rule engine provided by the present invention makes application development more efficient and flexible, and provides important support for the development and delivery of industrialized software.
