基于SSH2的OA项目1.0_20161206_需求分析与框架搭建

1. SSH项目

OA项目,办公自动化,将公司的数据,文档,流程实现在系统中的管理。

降低人员交流过程中的成本。提高办公的效率。

2 .系统管理

主要实现系统权限的管理,不同的用户登陆后看到菜单项不一样(菜单级的权限控制)。

2.1 RBAC权限模型

基于角色的访问控制(Role-Based Access Control)

总结:系统的权限管理中,是将相应资源的访问权限赋予角色,再将某个用户添加到某个角色

实体:用户表,角色表,资源表,资源_角色表,用户_角色表。

2.2RBAC的数据库模型

3 .搭建项目环境

3.1建立项目目录结构

3.2加入项目jar包

3.3导入js和css

3.4建立项目的配置文件
