基于Spring MVC + Spring + MyBatis的【人事管理系统】

资源下载：https://download.csdn.net/download/weixin_44893902/33163160

一、语言和环境

1. 实现语言：JAVA语言
2. 环境要求：IDEA/Eclipse + Tomcat + MySql
3. 使用技术：Spring Boot 或 SSM

二、实现功能

随着公司业务的发展，需要一款在线人事管理系统，主要功能如下：

1. 首页默认显示所有员工信息,如图1所示。
   
2. 鼠标悬停某行数据时，以线性过渡动画显示光棒效果，如图2所示。
   
3. 用户可以单独通过选择职位进行查询，也可以单独输入名字进行模糊查询，也可以两个条件一起查询，如图3所示。
   
4. 点击添加人员，跳转到添加页面。输入数据后，点击确定添加，跳转主页面并刷新数据。
   
5. 用户点击删除，弹出提示框，用户点击确定后，删除选中数据并显示最新数据，如图5所示
   

三、数据库设计

1. 创建数据库（cqsw）。

2. 创建数据表（tb_emp），结构如下。

字段名	说明	字段类型	长度	备注
emp_id	员工编号	int		主键，自增，增量为1
emp_name	员工名称	varchar	50	不能为空
emp_position	员工职位	varchar		不能为空
emp_in_date	员工入职时间	Date		不能为空
emp_salary	员工薪资	float		不能为空
dept_id	部门id	int		不能为空

1. 创建数据表（tb_dept），结构如下。

字段名	说明	字段类型	长度	备注
dept_id	部门编号	int		主键，自增，增量为1
dept_name	部门名称	varchar	50	不能为空
dept_address	部门地址	varchar		不能为空

四、实现步骤

SSM版本的实现步骤如下：

1. 创建数据库和数据表，添加测试数据（至少添加4条测试数据）。
2. 创建Web工程并创建各个包，导入工程所需的jar文件。
3. 添加相关SSM框架支持。
4. 配置项目所需要的各种配置文件（mybatis配置文件、spring配置文件、springMVC配置文件）。
5. 创建实体类。
6. 创建MyBatis操作数据库所需的Mapper接口及其Xml映射数据库操作语句文件。
7. 创建业务逻辑相应的接口及其实现类，实现相应的业务，并在类中加入对DAO/Mapper的引用和注入。
8. 创建Controller控制器类，在Controller中添加对业务逻辑类的引用和注入，并配置springMVC配置文件。
9. 创建相关的操作页面，并使用CSS对页面进行美化。
10. 实现页面的各项操作功能，并在相关地方进行验证，操作要人性化。
11. 调试运行成功后导出相关的数据库文件并提交。

五、实现代码

1、MySQL数据库
