Design And Implementation Of Code Generation Tool Based On J2EE System Of Database

With the development of J2EE technology, people in the development process of web operation system gradually to summarize repetitive work more and more. Although these repetitive work is not difficult, but developers still need to spend a lot of time to do coding and debugging work repetitive. Different developers write code quality is uneven. For the future of the maintenance work has also increased the difficulty. Code generation tool based on J2EE business system developed of this thesis, can help developers to reduce the repetitive coding work in a certain extent. At the same time ensure code quality, and improve development efficiency.From the operation mode point of view, many kinds of code generation for the J2EE development through plug-in style based on development tools to complete the design, this way can combine with development tools very well, but with the limitation of development tools running on. From the technology point of view, many code generation tool through the way of template, analysis database model via the third-party modeling tools to obtain the basic attribute information. This way is very reasonable, but the disadvantage is cannot obtain the connection information of the real database, and cannot complete the work to build the data source configuration in the project. In order to solve the problem above, the realization way in this thesis is analysis of the physical database structure as the core technology to achieve, and combined with the current mainstream open-source framework, through basic information of database structure to finish code generation. At the same time, to abandon the defect of plug-in code generation tool, this thesis will use the C/S programming language to design and develop a non plug-in code generation tool, which can be run on any windows operating system, and the generated code file can be imported into development tools to do secondary development. In the generation of objects, in addition to the basic management and front page file, there are techniques to make cascading style sheets file for show the effects of front pages.To research and design the code generation tool based on development of J2EE code operation system, can help developers to improve the writing quality code, save development and testing time, can liberate developers from the more repetitive coding work, and better into the realization of complex business logic of the work. At the same time to proposes some solutions for defects and better promote the development of the code generation technology.
