EJB容器的可扩展服务框架的设计和实现

Design and Implementation of an Extensible Service Framework of EJB Container

为满足各种各样的应用程序的需求容器的服务框架必须能支持各种服务的集成。该 EJB文给出了一个容器, EJBEJB的可扩展服务框架的设计和实现。该容器允许服务以的方式加入容器。当容器发生函数调用等事件时EJBInterceptorEJB, 容器自动触发这些相应的服务从而能实现透明地在容器中添加额外的服务。

To satisfy a wide-range of application demands, the service architecture of an EJB container must support the integration of all kinds of extended services. This paper presents the design and implementation of an extensible service frameworkof EJB container. Services can be integrated into the EJB container by implementing the Interceptor interface, and EJB container will trigger these services when certain event such as method invocation occurs. The extensible service framework allows services to be added transparently to the EJB container.
