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。

We discuss persistence , and existence and global stability of nonnegative equilibria for the system.

This thesis is just base on these questions, taking an information communication platform system development as background, based on MVC architecture, discussed Struts frame, Hibernator's ORM mechanism, persistent management of persistent object and Spring IoC technique and combining frameworks using three popular open source frameworks: For the presentation layer we will use Struts; for our business layer we will use Spring; and for our persistence layer we will use Hibernate to developing this system.

本论文正是基于上述问题出发，以开发一个信息交流平台系统为背景，对基于MVC模式的Struts框架、Hibernate的ORM机制和对持久对象持久化的管理以及Spring IoC技术进行了探讨。并整合这三种框架：表现层使用Struts；业务层使用Spring；持久层使用Hibernate进行系统的开发。
