人事管理系统

基于Spring+Springmvc+mybatis框架开发的管理系统

1.系统描述:

本系统分为6大模块:用户管理,部门管理,职位管理,员工管理,公告管理,文件下载,主要业务逻辑通过HrmService业务逻辑组件实现,可以使用这个逻辑组件封装DAO组件

2.开发工具及版本说明:

开发工具:
1.Eclipse
2.tomcat 8.5.11
3.使用maven管理项目
4.spring版本 4.1.6
5.mybatis版本 3.3.1
6.数据库:mysql

3.系统结构

  • 表现层:使用jsp作为表现层,并使用bootstrap前端框架美化传统html页面,使页面更加符合审美,结合EL表达式和JSTL标签库简化jsp开发做到无脚本jsp页面。
  • MVC层:使用springmvc作为MVC框架,对比struts2开发效率和性能更高且更符合面向对象的设计**
  • 业务逻辑层:由Spring IOC容器管理的业务逻辑组件组成
  • DAO层:由6个DAO组件组成
  • 领域对象层:由6个domain Object对象组成
  • 数据库服务层:使用MySQL数据库储存持久化数据,使用c3p0连接池,优化数据库连接
  • 使用junit整合spring进行单元测试,结合MockMvc进行服务端的单元测试
  • 利用页面标签实现分页功能
  • 添加统一异常管理

4.数据库设计

5.后序更新

下一步更新打算研究下sql语句的优化,优化系统查询效率
