构造了层次化的SOA模型,并提出了将服务使用层与服务实现层分层处理的策略.建立了基于服务的构件模型来实现SOA中的服务,使用接口来描述服务的语法,契约来描述服务的语义,并用卫式设计来模服务的行为.将接口作为结合构件技术与面向服务架构的关键.用实例说明了如何使用这种方法来实现面向服务的设计.此工作为利用构件技术解决面向服务架构中的服务实现问题奠定了基础.
A hierarchical SOA model is constructed and a strategy of layering the service usage layer and the service implementation layer is proposed.The service-based component model is established to implement the service in SOA, and the interface is used to describe the service syntax and contract to describe Service semantics, and the use of holistic design to model service behavior.The interface as a key component of the combination of component technology and service-oriented architecture.With examples of how to use this method to achieve service-oriented design.This work is to use component technology to solve The foundation for service implementation in service-oriented architecture is laid.
