Research on SOA-based Applications Based on AOP and Web Services

Web services are the best way to solve cross-platform, cross-language, loosely coupled distributed systems in web environment at present. But because of some non-functional attributes such as authorization, security, transaction, logging, etc. in web services, the adaptation and reuse of web services are decreased. It is difficult to maintain and extend SOA-based applications which are composed of them. In order to solve the above problems, Aspect-Oriented Programming is introduced to web services in this paper, the non-junctional attributes are separated and realized as aspectual services and the web services and aspectual services are weaved at SOAP level to construct the final system when the application runs.
