摘　　要：针对分布式实时动态数据库中间件实现的要求,提出并实现了基于拦截器模式的EJB容器中方法调用的设计,运用拦截器堆栈和组件化的设计提高了容器的模块化程度,降低了模块间的耦合程度,使用XML配置文件定制拦截器的调用,使得应用程序具有更大的可伸缩性和灵活性.An improved method of enterprise Java Beans (EJB) container design is introduced based on interceptors. This method is aimed at the demand of implementation of invocation for the EJB container in the distributed dynamic database middleware. Through the use of interceptor stack and components based design, the modularization of container is improved and the degree of coupling between different modules is decreased. The interceptor invocation is customized through XML configuration file, in this way the application modules gain more scalability and flexibility.
