1.登录界面
其中的图片存储路径可以替换成自己的，当然我这里的账号密码是先设置好的，其实可以做一个注册的功能，把账号密码存进文件中
package SchoolWork.ManagementSystem;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.*;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.Pane;
import javafx.scene.text.Font;
import javafx.stage.Stage;
public class Login extends Application {
@Override
public void start(Stage primaryStage) throws Exception {
Pane pane = new Pane();
Image image = new Image("SchoolWork/ManagementSystem/Login.jpg");
ImageView imageView = new ImageView(image);
imageView.setFitHeight(500);
imageView.setFitWidth(900);
pane.getChildren().add(imageView);
Label label1 = new Label("账号:");
Label label2 = new Label("密码:");
Font font = new Font(16);
label1.setFont(font);
label1.setLayoutX(40);
label1.setLayoutY(100);
label2.setFont(font);
label2.setLayoutX(40);
label2.setLayoutY(160);
TextField t1 = new TextField();
PasswordField t2 = new PasswordField();
t1.setLayoutX(85);
t1.setLayoutY(100);
t2.setLayoutX(85);
t2.setLayoutY(160);
Button b1 = new Button("登入");
b1.setLayoutX(80);
b1.setLayoutY(290);
b1.setOnAction(event -> {
if(t1.getText().equals("1515477256") && t2.getText().equals("1515477256zyh")){
primaryStage.hide();
Main main = new Main();
try {
main.start(new Stage());
} catch (Exception e) {
throw new RuntimeException(e);
}
} else{
LoginError loginError = new LoginError();
try {
loginError.start(new Stage());
} catch (Exception e) {
throw new RuntimeException(e);
}
}
});
Button b2 = new Button("登出");
b2.setLayoutX(180);
b2.setLayoutY(290);
b2.setOnAction(event -> {
primaryStage.hide();
});
pane.getChildren().addAll(label1,label2,b1,t1,t2,b2);
Scene scene = new Scene(pane, 300, 350);
primaryStage.setScene(scene);
primaryStage.setTitle("登入");
primaryStage.setResizable(false);
primaryStage.getIcons().add(new Image("SchoolWork/ManagementSystem/Ego_KaKa.jpg"));
primaryStage.show();
}
}2.当然要考虑到账号密码错误的情况
package SchoolWork.ManagementSystem;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.image.Image;
import javafx.scene.layout.Pane;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class LoginError extends Application {
@Override
public void start(Stage primaryStage) throws Exception {
Pane pane = new Pane();
Label label = new Label("账号或密码错误");
label.setTextFill(Color.RED);
label.setLayoutY(40);
label.setLayoutX(90);
pane.getChildren().add(label);
Button button = new Button("重新输入");
button.setLayoutY(90);
button.setLayoutX(100);
button.setOnAction(event -> {
primaryStage.hide();
});
pane.getChildren().add(button);
Scene scene = new Scene(pane, 250, 150);
primaryStage.setTitle("登入失败");
primaryStage.show();
primaryStage.setScene(scene);
primaryStage.getIcons().add(new Image("SchoolWork/ManagementSystem/Ego_KaKa.jpg"));
primaryStage.centerOnScreen();
}
}3.主界面
同样的，图片路径都可以换成自己的，需要注意的是因为这个主界面按钮个数比较多，所以我单独建了一个类
package SchoolWork.ManagementSystem;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.Pane;
import javafx.scene.text.Font;
import javafx.stage.Stage;
public class Main extends Application {
public static void main(String[] args) {
Application.launch();
}
public void start(Stage primaryStage) throws Exception {
Pane pane = new Pane();
BT bt = new BT();
bt.button(primaryStage);
Label label1 = new Label("学生成绩管理系统");
Font font = new Font(25);
label1.setLayoutX(350);
label1.setLayoutY(50);
label1.setFont(font);
Image image2 = new Image("SchoolWork/ManagementSystem/欢迎使用.png");
ImageView imageView2 = new ImageView(image2);
imageView2.setFitHeight(500);
imageView2.setFitWidth(900);
pane.getChildren().add(imageView2);
pane.getChildren().addAll(label1,bt);
Scene scene = new Scene(pane, 900, 500);
primaryStage.setTitle("学生信息管理系统");
primaryStage.setScene(scene);
primaryStage.setResizable(false);
primaryStage.getIcons().add(new Image("SchoolWork/ManagementSystem/Ego_KaKa.jpg"));
primaryStage.show();
}
}package SchoolWork.ManagementSystem;
import javafx.scene.control.Button;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;
public class BT extends Pane {
public void button(Stage pri){
Button button1 = new Button("输入信息");
button1.setLayoutX(400);
button1.setLayoutY(100);
button1.setMinWidth(100);
button1.setMinHeight(30);
Button button2 = new Button("查找信息");
button2.setLayoutX(400);
button2.setLayoutY(150);
button2.setMinWidth(100);

Button button5 = new Button("查看全部");
button5.setLayoutX(400);
button5.setLayoutY(330);
button5.setMinWidth(100);
button5.setMinHeight(30);
Button button6 = new Button("退出");
button6.setLayoutX(400);
button6.setLayoutY(380);
button6.setMinWidth(100);
button6.setMinHeight(30);
getChildren().addAll(button1,button2,button5,button6);
button1.setOnAction(event -> {
Input input = new Input();
try {
input.start(new Stage());
pri.hide();
} catch (Exception e) {
throw new RuntimeException(e);
}
});
button2.setOnAction(event -> {
Seek seek = new Seek();
try {
seek.start(new Stage());
pri.hide();
} catch (Exception e) {
throw new RuntimeException(e);
}
});
button6.setOnAction(event -> {
pri.hide();
Login login = new Login();
try {
login.start(new Stage());
} catch (Exception e) {
throw new RuntimeException(e);
}
});
button5.setOnAction(event -> {
allStudent allStudent = new allStudent();
try {
allStudent.start(new Stage());
} catch (Exception e) {
throw new RuntimeException(e);
}
});
}
}4.展示所有学生的界面
tableview控件可以方便的实现排序并且展示效果也更好
package SchoolWork.ManagementSystem;

}
