| Simple, fast and effective software development has been valued by the enterprise information management systems researchers and developers. However, the efficiency of system development will be declined as with enterprise business of horizontal extended and enterprise of information system development scale get larger and larger.Developers began to complain about work pressure overwhelmed, and non-technical problems often lead to serious mistakes in the development process. If we can put the repetitive code to a code generation tool by rules completed, it will be good to improve the efficiency of system development. At the same time the system developers will devote more energy and time to focus on implementing complex business which will greatly relieve their pressure.In view of the problems existing in the traditional software development model is proposed in this paper adapt to the frequent change of business enterprise information system development of code generation and hand written code combined with the development modeof work.This paper can be applied to code generation technology in an enterprise information management system development process, first of all to its feasibility were corresponding analysis, and through the contrast of existing code generation technology and code generation tool is proposed using metadata and template engine driven method to realize the system function module code generation.Then, this paper analysis of an enterprise information management system based on the architecture and technology implementation framework, extracted from the system design scheme of the information management system for, and the use of code generation needs of the system are analyzed and summarized.Secondly, according to the results of the requirements analysis, this paper implements a code generation method and the improved scheme.Finally, the specific process of generating enterprise information management system code is introduced in detail.In this paper after the study of related code generation technology with existing enterprise good infrastructure system, determined by FreeMark template engine combined with system database table metadata to realize the automatic generation of easy maintenance, easy expansion, easy transition characteristics of enterprise information management system code.This will keep height consistency in system of development mode and system of interface style.This has strong of affinity for enterprise information management system of the user; fordevelopment personnel as long as be familiar with it again on company current of development schema, and other in-service developers can be soon started doing system project that the separated employee in do of when a certain developer left. This realizes the enterprise information management system software for agile development in the real sense.The experimental results show that the code generation method can greatly improve the efficiency of enterprise information system development in the process of enterprise information system development. |
