摘要： 针对目前软件开发人员在手工开发Web Service程序过程中出现效率低下、容易出错等问题,本文基于低代码开发范式,结合需求原型化技术RM2PT,提出一种Web Service自动生成方法。首先,根据操作契约中的OCL表达式与数据基本操作的语义关系,建立两者之间的转换规则;其次,根据Web Service功能模块的代码特征构建转换模板;然后建立解析和处理需求模型的转换算法;最后,使用转换规则、转换模板和转换算法直接将需求模型自动转换为目标应用程序。通过使用4个软件开发案例对提出的方法进行验证,结果表明,约93.3%的系统操作可以实现自动生成。相比传统的软件开发模式,本文方法可以由需求模型自动生成标准化Web Service程序,提高了软件开发效率与质量。此外,本文方法支持快速原型开发和迭代开发,用户可以通过GUI验证、编辑与修改需求,重新生成应用程序。

Abstract: In order to design and implement reliable Web Service applications, developers still need to hand-code complex business logic, which is a tedious, time-consuming, and error-prone task. In order to solve the problem, a Web Service generation method based on the low-code development paradigm is proposed by combining requirements prototyping technology RM2PT. The proposed method establishes transformation rules for OCL expressions, extracts the code features of such applications, constructs transformation templates, and creates transformation algorithms for processed and parsing the requirements model. The method is demonstrated through four case studies. The result of the experiment shows that about 93.3% of the system operations can be generated automatically. Compared with traditional software development methodologies, the new approach can automatically generate standardized Web Service directly from requirements models, which can improve the efficiency and quality of software development. Furthermore, this approach can fully support iterative development in rapid prototyping in which requirements may keep changing, because the approach provides a GUI for users to validate, edit and change their requirements, and the approach can regenerate the Web Service accordingly.

Key words: requirements model, Web Service, low-code, UML, OCL
