项目摘要

We have investigated a new refactoring technique for web applications aiming at the better reliability and maintainability. Web applications am different from the conventional software system in that (1) they are executed by events over web pages., and (2) they are built as the combination of componets deserted by various languages, which are not necessarily object-oriented As scaled up the web applications or enhanced their functionalities, the reliability and maintainability generally become worm. Web applications are basically captured by the object orient manner as the reactive systems. Thus, we tried to investigate new enhanced refactering techniques for web applications.To start with, we proposed a refactoring technique for Apache Struts framework with an abstract operational model. However, it is restricted to a certain class of Struts framwork in a small scale. We then needed to investigate appropriate testing methods and devise a semantic model for refactoring, where software is restructured or rewritten to have better properties. By testing behavior, it is ensured that the original properties are preserved. We proposed a testing method for web applications and how to automate the method. And we investigated some semantic models suitable for round-trip refactoring of web applications. During the research period, we have not yet completed the development of refactoring, but through the refactoring of Apache Struts, and the testing method and semantic models, we believe that we now substantially have the results for refactoring web applications.

我们已经研究了一种新的重构技术的Web应用程序，旨在更好的可靠性和可维护性。Web应用程序与传统软件系统的不同之处在于：（1）它们通过网页上的事件来执行，（2）它们是由各种语言抛弃的组件组合而成的，这些组件不一定是面向对象的。随着Web应用程序的规模扩大或功能增强，可靠性和可维护性通常变得越来越差。Web应用程序基本上是以面向对象的方式捕获的，是反应式系统。因此，我们试图研究新的增强重构技术的Web应用程序。首先，我们提出了一种重构技术的Apache Struts框架与抽象的操作模型。但是，它仅限于某一类小规模的Struts框架。然后，我们需要研究适当的测试方法，并设计一个重构的语义模型，其中软件被重构或重写以具有更好的属性。通过测试行为，可以确保原始属性得到保留。我们提出了一种Web应用程序的测试方法，以及如何自动化的方法。并研究了适用于Web应用程序双向重构的语义模型。在研究期间，我们还没有完成重构的开发，但是通过对Apache Struts的重构，以及测试方法和语义模型的研究，我们相信我们现在已经基本上有了重构Web应用的成果。
