Web应用系统跨多级防火墙访问企业数据资源的解决方案

A Solution That Allows Web Applications to Transverse Multi-Level Firewalls to Access Enterprise Data Resources

分析了企业网的结构,针对防火墙在保障网络安全的同时严格限制外部访问的情况,提出了Web应用系统跨越多级防火墙访问企业数据资源的软件架构。以汽车站客运班次查询为例,基于轻量级JavaEE平台开发了采用该架构的应用系统,阐述了该解决方案的具体实现方法和步骤。并进一步分析了应用服务器,给出了提高应用服务器性能的若干方法。最后,对方案进行了评价,指出了该方案易于扩展、便于维护、灵活性高的特点。实践表明,该方案具有较好的推广应用价值。

This paper analyses the enterprise network structures.According to the situation that firewalls protect enterprise networks with strict restrictions on external accesses,this paper proposes a software framework that allows web applications to traverse multi-level firewall to access enterprise data resources.Taking the bus station passenger transport schedule query as the example,this paper describes the application system developed with this software framework based on the lightweight JavaEE platform,and presents the detailed implementation methods and procedures.This paper also analyses the application server and describes methods to improve the application server performance.The solution system is easy to extend and maintain with high flexibility.Practical applications prove that the solution has good popularization and application values.
