摘要
介绍了互联网的发展对网络服务器性能的需求。分析了J2EE体系结构的分层和组件的特性。进行了J2EE Web应用的分层软件架构风格的功能优化分配．以便使网络服务器在面对大规模并行访问时系统的响应速度和吞吐量能够满足高端应用的需求。借助于EJB独有的生命周期回调机制。论证了EJB承载企业逻辑的性能优势。分析了J2EE程序的编译特点对系统性能的影响。得出了用EJB组件基础设施可以构筑高效、健壮的高端J2EE Web应用的结论。
The paper introduces the intemet development situation and the requirement for performance provided by intemet application server.The layer and component characters of J2EE software architecture are explained.The function deployment for layer style software architecture of J2EE web application is optimized so that the internet application server can provides high response speed and throughput for top application.The paper discusses the system performance advantages when EJB holds business logic. The influence to system performance resulted from J2EE program＇ s compiling characteristic is also analyzed.In the end,the conclusion that effective and robust top J2EE web application can be built with EJB component infrastructure is drawn.
