基于Spring MVC + Spring + MyBatis的【学生信息管理系统】

资源下载:https://download.csdn.net/download/weixin_44893902/45603211

练习点设计: 模糊查询、删除、新增

一、语言和环境

  1. 实现语言:JAVA语言。
  2. 环境要求:MyEclipse/Eclipse + Tomcat + MySql。
  3. 使用技术:Jsp+Servlet+JavaBeanSpringMVC + Spring + Mybatis

二、实现功能

随着数字化信息的发展,现需要制作学生信息管理系统,主要功能如下:
1.首页默认显示所有学生信息,如图1所示。
基于Spring MVC + Spring + MyBatis的【学生信息管理系统】
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.用户输入学生名称,点击查询,则完成模糊查询,显示查询结果,如图3所示。
基于Spring MVC + Spring + MyBatis的【学生信息管理系统】
4.用户点击删除,则弹出提示框,用户点击确定后,删除选中数据并显示最新数据,如图4和图5所示。

5.用户点击“新增”按钮,则打开新增页面,填写完相关信息后点击新增按钮,增加学生信息数据到数据库,且页面跳转到列表页面展示最新数据,如图6和图7所示。

三、 数据库设计

1.创建数据库(stu_db)。
2.创建数据表(student),结构如下。

字段名 说明 字段类型 长度 备注
id 编号 int 主键,自增
name 学生姓名 varchar 50 不能为空
age 年龄 int 不能为空
classes 班级名称 varchar 50 不能为空
birth 出生日期 date 不能为空

四、推荐实现步骤

1.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
