The Study And Design Of Code Generation Of Frontend And Backend Based On The User’s Guidance In The Development Of Workflow

Code generation in the development of work flow means the system used to generate the source code of workflow application. By parsing the source code of static web form used for human-computer interaction, according to a certain logic, the system generates the web frontend dynamic form code used for human-computer interaction and the backend server source code used for processing data in the workflow application system.Currently, manual programming is still the software development approach adopted by most programmers. The drawback of such development mode is the slow development speed, high development cost and that the programmers inevitably do much repetitive work. Therefore, some large software projects prolong the development cycles, the development cost of software is beyond the expectation and the software performance is below the level expected. Some software projects even are forced to terminated because so. Therefore, the software developers constantly explore the higher software development method. In such background demand, code generation technology is proposed.The technique of code generation is quite new, it is on the stage of rapid development. The technique of code generation has been used in many system developments. Although code generation technique is flawed in some respects, undoubtedly, it greatly shortens the software development cycle and promotes the development of software industry.This paper analyzes the the current development condition of code generation at home and abroad, and the feasibility of the code generation’s application to the work flow system development, and analyzes the current implementations of code generation from several aspects and then the comparison of a variety of code generation modes is made. The generation mode of this paper is proposed then, the generation mode of this paper is based on the static web form used for human-computer interaction, template engine files and Eclipse plug-in technique.According to the business need, the workflow system developers design the static web form used for human-computer interaction by the web form designer. The designation of the static web form parsing engine is the core of code generation system. The code generation system is added to the Eclipse plug-in which facilitates the workflow developers.Finally, through the practical application of the system, the executing procedure of the workflow code generation system is illustrated. Through the analysis of running result and the system speed, the code generation system is confirm to the expectation and the feasibility of the code generation in workflow system development is verified.
