本文介绍了一个基于MyBatis的学生信息管理系统的设计与实现过程。系统包括学生、教师、课程及成绩管理模块，采用Maven进行项目管理，并实现了登录、注册、选课、成绩录入等功能。文章详细展示了数据库设计、项目结构、界面设计及代码实现。

目录
一、建库建表
Table student
用于记录学生的基本信息
Table stu_classes
用于记录学生的选课信息
Table stuscore
用于记录学生的成绩
Table teacher_course
用于记录老师的信息
下面是该库的sql文件：
SET FOREIGN_KEY_CHECKS=0;
DROP TABLE IF EXISTS `student`;
CREATE TABLE `student` (

INSERT INTO `teacher_course` VALUES ('170', 'yang', '杨**', 'filmapp', '00187');
二、项目结构
Package dao
存放对数据库操作的接口以及mapper映射文件
Package model
存放实体类以及模型类
Package utils
存放自定义工具类——用于返回Sqlsession类型
Package viewAndcontroller
存放所有的fxml类型界面文件、css样式文件、图片以及控制器类
Class Main
主类
Package java.resources
存放数据库属性配置文件、所有的界面FXML文件、css样式文件以及图片，便于Maven在compile时将这些文件编译到target的classes目录下。
需要手动将image目录拷贝到target目录下
pom.xml
在该文件中加入mybatis、mysql驱动等依赖jar包
Directory META-INF
JavaFx Application 构件的属性
用于将本项目打包成exe可运行文件。
三、项目测试
登录界面
注册界面
登录功能
登录学生界面
登录老师界面
注册功能测试
当输入不合理或者输入已注册过的学号或用户名时，给出错误提示窗口
学生选课功能测试
学生的成绩面板课程发生变化
选课必须为两门
老师修改成绩功能测试
学生的成绩面板已成功改变
当输入小于0或者大于100时给出提示窗口
四、项目的打包
打包可执行jar包
由于本项目采用Maven管理，因此很容易进行打包。
在idea的右侧打开Maven菜单点击Package操作即可打包可执行jar包到target目录下。
但是此情况打包的jar包是不包含项目所依赖包的，于是需要导入以下插件，将依赖包一同打包。
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>com.allen.capturewebdata.Main</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
点击右侧Maven菜单中插件中的: assembly:assembly，即可在target目录下生成一个"**-jar-with-dependencies.jar"的jar包
转化成可执行的exe文件
–>文件打开项目结构–>点击构件
添加一个JavaFx Application构件
点击Create Manifest… 生成META-INF目录
接下来添加主类
然后右击右侧依赖包选择置于 Output Root
点击应用、确定
最后选择构建->编译 Artifacts…->Rebuild
成功在项目的out目录下生成了构件目录
以下为可执行的exe文件（图标可以根据需要更改）
五、附上具体代码
