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 BootSSM

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
