面向复杂民航业务的中间件架构设计与实现

摘要

针对民航业务实时并发请求多、业务功能复杂多变、数据量大、可靠性要求高等业务特点,分析当前流行服务器架构的优缺点,将服务划分阶段,在民航旅客服务信息系统中引入分阶段的事件驱动架构(staged event-driven architec-ture,SEDA),叙述系统工作机制,给出具体实现。实例结果表明,基于 SEDA的服务器软件架构比传统的服务器软件架构拥有更好的处理高并发请求的能力,在易用性和可维护性方面相比传统架构有很大提高。%For the features of civil aviation business request such as complication,large data amount,high concurrency and relia-bility,merits and drawbacks of several prevalent server architectures were analyzed.Service was divided into stages and staged event-driven architecture (SEDA)was introduced into passenger service system.The working mechanism of the system was stated in detail and a kind of implementation was given.An Example verify that servers applied with SEDA has better perfor-mance than those based on traditional model when dealing with high concurrency requests,and they also have better maintain-ability and usability.
