Third-Party Logistic of Warehouse Management System Framework provides a series of reusable groupware, such as persistence layer which introduces Dynamic Value Object, Value List Hander and Command pattern. It encapsulates the details of accessing database and affords the interface of different persistence layer framework. Based on Asynchronous JavaScript and XML, we develops the client validity check engine, dynamic cascading menu and common, dynamic tree structure groupware, as well as a set of tag library which include query, pagination, cache and so on. It reduces the code redundancy and predigests the development of interface layer enormously.

第三方物流管理系统框架提供了一系列可复用组件，例如采用动态VO、值列表处理器以及命令模式的持久层组件，封装了数据库访问细节，并为不同的持久层框架提供调用接口；基于Ajax(Asynchronous JavaScript and XML)技术的客户端校验引擎、动态级联菜单以及通用动态树型结构组件，一系列查询、分页、缓存等标签库则减少了表示层的代码冗余，简化了表示层开发；基于SSL登录以及基于角色的访问控制的安全子系统则初步实现了数据安全传输和权限控制；此外基于Web服务的企业应用集成模型为今后系统集成、数据共享提供了有益探索。

This thesis deeply researches the J2EE security strategy on the application tier of enterprise system. The security strategy predigests the information security model and meets the security requirements expediently. But there are some disadvantages when the security requirements become more complex. The expositive security on the Web-Tier can not offer more information for authentication; there is no authentication for EJB-Tier to use, make the EJB-Tier depend on the Web-Tier; J2EE uses database or application server to manage the role information. Use database to manage the role information will increase the complex of enterprise application, and the way of application server will reduce the ability of migrate other J2EE platform. To solve these problems, the thesis designs an improved security strategy model.

本文从企业级系统应用层安全的角度出发，深入研究J2EE多层体系结构的安全策略模型。J2EE提供的安全策略简化了系统的信息安全模型，能够很方便地满足基于J2EE的分布式应用系统的安全需求，但是在面对更加复杂的安全需求时，J2EE安全策略在验证授权和角色管理中还存在不足之处：其在Web层的声明式验证机制无法为用户提供更多验证信息，可扩展性较差；在EJB层缺少业务逻辑层可供采用的验证机制，而是借助于Web层的验证机制，其耦合程度较高有悖于业务逻辑分离于表现逻辑的原则；在角色管理方面，J2EE采用数据库或者应用服务器来管理角色信息，其中，数据库管理角色的方式增加了应用开发的复杂度，应用服务器管理角色降低了系统的可移植性，两者都具有片面性。
