前言
这是学习过MySQL和JavaFX所做的一个阶段作品，不过内容有点混乱只用了三个类，这是第一次能够比较清晰的写出作品，虽然还有很多不足，但是依然收获满满。
可以直接看最下面的全码，你一定能看懂。
一、ER图
二、系统结构图
三、学生登录和注册界面
//初始界面，学生登录界面
public static void begin() {
stage.setTitle("学校管理系统");
GridPane gp = new GridPane();
// 调整空隙
gp.setHgap(10);
gp.setVgap(10);
// 新建文本标签
Label l1 = new Label("学生名称");
// 新建输入框
TextField name = new TextField();
// 新建文本标签：用户密码
Label l2 = new Label("登录密码");
// 新建密码框
PasswordField pwd = new PasswordField();
gp.add(l1, 0, 0);
gp.add(name, 1, 0);
gp.add(l2, 0, 1);
gp.add(pwd, 1, 1);
Scene sc = new Scene(gp, 500, 400);
stage.setScene(sc);
gp.setAlignment(Pos.CENTER);
// 按钮的创建
Button b1 = new Button("学生登录");
Button b2 = new Button("学生注册");
Button b3 = new Button("教师登录");
Button b4 = new Button("管理员");
//字体类型和大小
gp.setStyle("-fx-font-family: 'FangSong';-fx-font-size: 18;");
gp.add(b1, 0, 2);
gp.add(b2, 1, 2);
gp.add(b3, 0, 3);
gp.add(b4, 1, 3);
b1.setOnAction(a -> {
try {
if (link.pupil(name.getText(), pwd.getText(),stage)) {
score(name.getText(), pwd.getText());
}
} catch (Exception e) {
e.printStackTrace();
}
});
b2.setOnAction(a -> {
longht();
System.out.println("前往注册");
});
b3.setOnAction(a -> {
try {
right();
} catch (Exception e) {
throw new RuntimeException(e);
}
});
b4.setOnAction(a ->{
try {
tuble();
} catch (Exception e) {
throw new RuntimeException(e);
}
});
}// 学生注册界面
public static void longht() {
GridPane gp = new GridPane();
stage.setTitle("学校管理系统");
// 设置居中方式
gp.setAlignment(Pos.CENTER);
// 调整空隙
gp.setHgap(10);
gp.setVgap(10);
// 新建文本标签
Label l1 = new Label("名称");
// 新建输入框
TextField f1 = new TextField();
// 新建文本标签：用户密码
Label l2 = new Label("密码");
// 新建密码框
PasswordField f2 = new PasswordField();
Label l3 = new Label("性别");
//性别单选框
ToggleGroup group = new ToggleGroup();
RadioButton men = new RadioButton("男");
RadioButton miss = new RadioButton("女");
HBox h1 = new HBox();
// 按钮的创建
Button b1 = new Button("注册");
// 注册按钮的创建
Button b2 = new Button("取消");
//字体类型和大小
gp.setStyle("-fx-font-family: 'FangSong';-fx-font-size: 18;");
b1.setOnAction(a -> {
String name = f1.getText();
String pwd = f2.getText();
String sex = "男";
if (miss.isSelected()) {
sex = "女";
}
if (f1.getText()!=null&&!f1.getText().trim().equals("")&&f2.getText()!=null&&!f2.getText().trim().equals("")){
try {
// 储存在数据库
link.rigister(f1.getText(), f2.getText(), sex);
tips("注册成功,请返回登录",stage);
} catch (Exception e) {
throw new RuntimeException(e);
}
}else {
tips("请输入完整",stage);
}
System.out.println("姓名:" + f1.getText());
System.out.println("性别:" + sex);
System.out.println("密码:" + f2.getText());
});
b2.setOnAction(a -> {
begin();
});
h1.getChildren().addAll(l1, l2, b1);
men.setToggleGroup(group);
miss.setToggleGroup(group);
men.setSelected(true);
h1.getChildren().addAll(men, miss);
//用户名
gp.add(l1, 0, 0);
gp.add(f1, 1, 0);
//密码
gp.add(l2, 0, 1);
gp.add(f2, 1, 1);
//用户性别
gp.add(l3, 0, 2);
gp.add(h1, 1, 2);
//按钮
gp.add(b1, 0, 3);
gp.add(b2, 1, 3);
//生成场景并完成布局绑定，同时设置场景大小
Scene sc = new Scene(gp, 500, 400);
stage.setTitle("用户注册");
stage.setScene(sc);
stage.show();
}
四、教师登录界面
管理员登录界面和教师登录界面相通，只是SQL语句不同，所以进入不同的界面，大部分的代码是相同的，教师不能自己注册，只能由管理员给其添加。
//教师登录界面
public static void right() {
// 窗口名称
stage.setTitle("教师登录");
GridPane gp = new GridPane();
// 调整空隙
gp.setHgap(10);
gp.setVgap(10);
// 新建文本标签
Label l1 = new Label("教师名称");
// 新建输入框
TextField name = new TextField();
// 新建文本标签：用户密码
Label l2 = new Label("教师密码");
// 新建密码框
PasswordField pwd = new PasswordField();
Label l3=new Label("教师登录界面");
gp.add(l1, 0, 1);
gp.add(name, 1, 1);
gp.add(l2, 0, 2);
gp.add(pwd, 1, 2);
// gp.add(l3,0,0);
Scene sc = new Scene(gp, 500, 400);
// 设置居中方式
gp.setAlignment(Pos.CENTER);
// 按钮的创建
Button b1 = new Button("登录");
// 注册按钮的创建
Button b2 = new Button("取消");
//字体类型和大小
gp.setStyle("-fx-font-family: 'FangSong';-fx-font-size: 18;");
b1.setOnAction(a -> {
try {
link.login(name.getText(), pwd.getText(),stage);
} catch (Exception e) {
throw new RuntimeException(e);
}
});
b2.setOnAction(a -> {
try {
begin();
} catch (Exception e) {
throw new RuntimeException(e);
}
});
gp.add(b1, 0, 3);
gp.add(b2, 1, 3);
stage.setScene(sc);
}
五、学生登录后界面
学生只能查询到自己的基本信息，不能做任何的修改。
//学生查询界面
public static void score(String name, String code) throws Exception {
Student student = new Student();
link.score(student, name, code);
int id = Integer.parseInt(student.getC0());
link.scor(student, id);
Label l0 = new Label("学号 : " + student.getC0());
Label l1 = new Label("姓名 : " + student.getC1());
Label l2 = new Label("密码 : " + student.getC2());
Label l3 = new Label("性别 : " + student.getC3());
Label l4 = new Label("语文 : " + student.getC4());
Label l5 = new Label("数学 : " + student.getC5());
Label l6 = new Label("英语 : " + student.getC6());
Label l7 = new Label("化学 : " + student.getC7());
Label l8 = new Label("历史 : " + student.getC8());
Label l9 = new Label("班级 : " + student.getC9());
Label l10 = new Label("总分 : " + (student.getC4() + student.getC5() + student.getC6() + student.getC7() + student.getC8()));
Button b2 = new Button("返回");
GridPane gp = new GridPane();
gp.add(l0, 2, 0);
gp.add(l1, 2, 2);
gp.add(l2, 2, 3);
gp.add(l3, 2, 4);
gp.add(l4, 2, 5);
gp.add(l5, 2, 6);
gp.add(l6, 2, 7);
gp.add(l7, 2, 8);
gp.add(l8, 2, 9);
gp.add(l9, 2, 1);
gp.add(l10, 2, 10);
gp.add(b2, 2, 12);
// 调整空隙
gp.setHgap(10);
gp.setVgap(10);
b2.setOnAction(a -> {
begin();
});
gp.setAlignment(Pos.CENTER);
//字体类型和大小
gp.setStyle("-fx-font-family: 'FangSong';-fx-font-size: 18;");
Scene sc = new Scene(gp, 300, 450);
stage.setScene(sc);
stage.show();
}六、教师登录后界面
教师能够对学生情况进行增删改查。
一、 查询
- 模糊查询
- 姓名查询
- 班级查询
// 名字模糊<<<<查询>>>>>表格--------------教师---查询学生----班级或姓名
static void refer(String name,int squad) {
BorderPane bp = new BorderPane();
stage.setTitle("学校管理系统");
Scene sc = new Scene(bp, 870, 450);
stage.setScene(sc);
stage.show();
FlowPane fp1 = new FlowPane();
Label l1 = new Label("名称");
TextField f1 = new TextField();
Label l2 =new Label("班级");
TextField f2 =new TextField();
Button b1 = new Button("查询");
Button b2 = new Button("返回");
ArrayList students = new ArrayList<>();
//学生成绩表格 //id查询后表格
magin1(bp, students, name,squad);
b1.setOnAction(a -> {
if (!f1.getText().trim().equals("") && f2.getText().trim().equals("")) { //姓名
refer( f1.getText(), 1);
} else if (f1.getText().trim().equals("") && !f2.getText().trim().equals("")) { //班级
refer(f2.getText(), 2);
} else if (!f1.getText().trim().equals("") && !f2.getText().trim().equals("")) { //姓名+班级
refer1(f1.getText(), f2.getText());
}
});
b2.setOnAction(a -> {
deng();
});
fp1.getChildren().addAll(l1, f1,l2,f2, b1, b2);
fp1.setHgap(15);
fp1.setPadding(new Insets(20));
bp.setTop(fp1);
} 二、增加
这里是重新调用了注册方法，不过加入了一个性别判断。
//判断性别
if(f4.getText().equals("男") || f4.getText().equals("女")){
System.out.println("性别合规")
} else {
System.out.println("性别不合规")
}三、删除
输入ID，就能直接运用SQL语句把信息从数据库删除，
四、修改
这里进行了ID不能修改的命令，并且判断了性别是否合规。
//学号不可更改
f1.setEditable(false);
//<<>>是ID那个输入框 七、管理员登录
管理员能够同时修改学生和教师的信息，其中对学生信息的修改和教师对学生信息的修改功能相同。对教师信息的修改添加了电话号码长度的判断
一、教师管理
二、学生管理
和教师对学生的管理相同

九、数据库
我的数据库是用的Navicat软件，可以运用触发器，更好的实现功能，当一个表改变的时候使另一个表也改变，不仅是删除，注册的时候也需要使用到。
