基于Spring MVC + Spring + MyBatis的【学生管理管理系统】

资源下载：https://download.csdn.net/download/weixin_44893902/45602690

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+JavaBean或SpringMVC + Spring + Mybatis。

二、实现功能

随着“朝阳会计培训学院”人数的增多,现需要制作学生管理系统，主要功能如下：

1.首页默认显示所有学员信息，如图所示。

2.鼠标悬停某行数据时，该数据显示橙色，如图所示。

3.用户输入学生姓名时，点击搜索，则完成模糊查询，显示查询结果，如图 3 所示。

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“录入”链接,则打开新增页面,填写完相关信息后，如果不想录入点击“取消”回到主页，录入则点击录入按钮，增加学员信息数据到数据库,且页面跳转到列表页面展示最新数据，.

三、 数据库设计

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

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 5 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。

2.JSP 版本的实现步骤如下：
（1）按以上数据库要求建库、建表，并添加测试数据。
（2）创建 Web 工程并创建各个包，导入工程所需的 jar 文件。
（3）创建实体类。
（4）创建 Servlet 获取用户不同的请求，并将这些请求转发至业务处理层相应的业务方法。
（5）创建业务处理层，在其中定义业务方法实现系统需求，在这些业务方法中需要执行 DAO 方法。
（6）创建 BaseDAO 工具类，使用 JDBC 完成数据表数据的查询、删除和添加。
（7）编写 JSP 页面，展示数据的查询结果。

五、实现代码

1、MySQL数据库
