Technical Field
The invention relates to the technical field of computers, in particular to a data source definition method and device for rule management.
Background
In a rule management system, the system may define operation rules, use system-defined fields, or user-defined fields whose values are passed to the rules engine for operation with the rules at the time of rule execution. The field values come from two sources, one is that the API caller passes in through API parameters, and the other is that the API caller is hard coded in the code and is obtained from the outside at runtime. The rule management system provides custom rules, but the fields required by the custom rules are also limited to these two acquisition modes. In the mode that the caller passes in through the parameter, the field used by the rule is exposed to the outside, which is not beneficial to the security of the rule. In a hard coding mode, fields used by the rules are associated with code development deployment, so that the development period of the rules is long, and the rules are not beneficial to adjustment and rapid development.
In view of the above problems in the related art, no effective solution has been proposed at present.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
As shown in fig. 1, according to an embodiment of the present invention, a data-derived definition method for rule management is provided, which is applicable to a rule management system or other systems related to rule management. The data source definition method for rule management of the invention comprises the following steps:
s10, customizing parameter information accessed by the data source in a visual interface; and
s20, generating a return value for the configuration rule according to the parameter information.
Through the technical scheme, a user can customize a data source, obtain the return value of a data field and apply the return value to a rule; by using a whole-process visual interface, rule managers can quickly customize rules, code development is avoided in the middle, and the safety of the rules is enhanced.
In one embodiment, the parameter information for data source access includes: basic information of data access, input information of data access and metadata of data access output. Wherein the basic information includes: a data access type and parameters required for the type. Wherein, the metadata of the data access output comprises: a field, a resolution of the field, and a field type.
To support custom data source access, a variety of commonly used data access types may be provided, such as access MYSQL database, ORACLE database, restul API methods, and the like.
As shown in fig. 2, after the user selects the type of data access provided by the system, the necessary parameter information for selecting the mode is input on the visualized page. For example, in the RESTFUL API access type, a user needs to set a URI (Uniform Resource Identifier) of the access and select a format of the returned data. In the MYSQL access type, the user needs to input an SQL statement for query in addition to the SQL URI. Template parameters may be supported in the user's input, and these template parameters may be replaced at run-time by values of the context. When configuring data access, a user needs to define input and output, and the input and output are used as self-description data of the data access and are exposed to a system. The output field of the data access can become a self-defined field which can be selected by the rule, and the user directly selects the field when configuring the rule without paying attention to the data access of the generated field.
In one embodiment, step S10 includes: inputting basic information in a visual interface, and using a template when inputting the basic information; and querying according to the basic information to obtain a return value.
Wherein querying according to the base information to obtain the return value comprises: the template in the basic information is replaced with the input information.
In one embodiment, step S20 includes: generating a key-value pair from the metadata description and returning the key-value pair to the caller.
In one embodiment, the data derivation definition method of the present invention further comprises the steps of: s30, checking the parameter field of the rule before executing the rule, and initiating a call for data access when the parameter field is not present in the namespace of the context. Wherein, data is collected from the context according to the basic information of data access in the parameter information; initiating the call of data access by using the collected data; the returned values in the form of key-value pairs are populated into the namespace of the context.
For a better understanding of the present invention, the data derivation definition method of the present invention is described in detail below with reference to fig. 2. As shown in fig. 2, the data derivation definition method of the present invention includes the following steps in a specific implementation:
s201, the basic information of data access includes a data access type and parameters required by the data access type. The part of information is input by the user through the interactive mode of the interface. The template may be used by the user when entering the basic information. The code of data access will initiate external inquiry according to the part of information to obtain the calling return value.
And S202, inputting information of data access. This information is entered by the user on the interface, in the form of metadata, stored with the basic information of the data access, describing the conditions under which the data access is running. The data access code, when invoked, replaces the template in the basic information parameters with this portion of the input data.
S203, accessing the metadata of the output by the data, wherein the information is input by the user on the interface, and the metadata and the basic information of the data access are stored together to describe the output of the data access. The output definition contains the name of the field, the way the field is parsed from the data access outbound query result (JSONPATH, XMLPATH), and the field type. When saving the data access definition, the system generates custom fields from the output metadata, which are available to all rules. The data access call will generate a key-value pair according to the output description and return the key-value pair to the caller.
S204, the system executes the rule by using an open source DROOLS engine, checks parameter fields of the rule before executing, when the fields come from data access and the value of the fields does not exist in the context namespace, the system initiates the calling of the data access, firstly collects data from the execution context according to the data access input metadata, transmits the data to the data access code in the form of key-value pairs to initiate the calling of the data access, and then fills the key-value pairs of the data access back to the context namespace. The field-values in the namespace are then passed to the DROOLS engine along with the rules to execute the rules.
As shown in fig. 3, according to an embodiment of the present invention, there is also provided a data source definition apparatus for rule management, including:
the visual interface module 10 is used for customizing parameter information accessed by a data source;
and the output module 20 is connected to the rule executing device 30, and the output module 20 is used for generating a return value for configuring the rule according to the parameter information.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
