Description
Technical field
The present invention relates to technical field of aerospace, particularly relate to a kind of rule engine adjustment method and system.
Background technology
Traditional IT technology aims to provide the ability of business processes information, along with the raising of IT application in enterprises degree, traditional IT architecture mode can not meet the demand of enterprise, the operation of enterprise produces many business rule, perform these rules by rule engine, meet the flexible commercial requirements fast of enterprise. For IT system, rule write and management becomes enterprise's issues that need special attention.
Manifestation and the ability to express of rule rely on specific rule engine system. Rule engine is developed by reasoning engine, is a kind of embedding assembly in the application, it is achieved that business decision-making separated from application code, and the semantic modules using predefine writes rule. The regular kind that different regular engines is supported is also different with mode, usually divides, it is possible to be divided into technical regulation, decision table rule, class natural language commercial affairs rule.
Technical regulation is the rule script using programming on bottom layer language, is mainly used in as decision table rule and class natural language commercial affairs rule provide data encasement and aftertreatment, is generally that the developer on backstage is used.
Decision table rule is a kind of figure instrument in form shape, and more for describing process judgement condition, each condition combines again, has the situation of multiple decision-making scheme mutually. Every provisional capital of decision table can be become a technical regulation by rule engine internal usually.
Class natural language commercial affairs rule is by mapping relation, and usability of program fragments is become natural language, and in program, variable is illustrated as input frame, is represented by the form of " if/so ". Class natural language rule can dynamic-configuration conditional content, it is believed that be more flexible than decision table, it is possible to a kind of technical regulation towards business people is out of shape.
In the dynamic packing platform of the many travelling products of civil aviaton, the regular engine selected be JBossDrools increase income rule engine, apply a large amount of technical regulations in actual use, these rules are organized with the document form of class Java language. But in the management of project procedure, technical regulation is compared with Java program and be there are some defects, can not support that enterprise-level application manages well, its defect is as follows: 1) technical regulation name space can not strictly be named according to bag name+rule name, preserves according to directories/files;2) technical regulation is write arbitrarily, can not carry out when writing compiling front grammer inspection, can only find mistake by running; 3) tradition Java development environment (such as Eclipse) does not support to be carried out by technical regulation grammer inspection and grammer is assisted, and development efficiency is low; 4) technical regulation code cannot find, by code optimization tool (such as Sonar), the code quality problem that rule is write; 5) part rule file cannot be debugged.
The technical problem to be solved in the present invention is the ripe Development System making full use of Java language, explain technology set up the definition of a set of Java-Rule specification by rule engine simulation execution, Java, performance history is directly write Java code, in test by rear, translation program is utilized to generate corresponding technical regulation.
