摘要
把面向方面编程的思想引入到Web服务中,将其横切关注点(日志、事务、权限认证等)实现为方面服务,在系统执行时用编织器在SOAP消息层编织Web服务和方面服务来构建最终系统,并结合面向服务软件体系结构和J2EE的多层架构提出一个基于方面服务和Web服务的软件架构。给出一个应用该软件架构的实例。
Aspect-Oriented Programming（AOP} is introduced to Web services, whose crosscutting concerns such as logging, transaction, authorization, etc. They are separated and realized individually as aspectual services. When the system runs, a weaver weaves them at SOAP message level to construct the final system. Combining Service-Oriented Architeeture（SOA） and J2EE multi-tier architecture, a multi-tier system architecture based on aspectual services and Web services is proposed. And a case is designed according to the system architecture.
