2. Frontend: JavaFX Application
Step 1: Create the JavaFX Project Structure
Use an IDE like IntelliJ IDEA or Eclipse with JavaFX support.
Step 2: Design UI using FXML
Create a basic UI for the JavaFX application using FXML files. For simplicity, we'll focus on the main screens.
Main.fxml
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<AnchorPane xmlns:fx="http://javafx.com/fxml" fx:controller="com.campus.eventmanagement.controller.MainController">
<children>
<VBox spacing="10">
<Label text="Campus Event Management System" style="-fx-font-size: 20px;"/>
<Button text="Register for Event" onAction="#handleRegisterForEvent"/>
<Button text="View Events" onAction="#handleViewEvents"/>
<Button text="Create Event" onAction="#handleCreateEvent"/>
</VBox>
</children>
</AnchorPane>
MainController.java
package com.campus.eventmanagement.controller;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.Alert;
public class MainController {
@FXML
private void handleRegisterForEvent(ActionEvent event) {
// Implementation of registering for an event
showInfoAlert("Feature Coming Soon!");
}
@FXML
private void handleViewEvents(ActionEvent event) {
// Implementation of viewing events
showInfoAlert("Feature Coming Soon!");
}
@FXML
private void handleCreateEvent(ActionEvent event) {
// Implementation of creating an event
showInfoAlert("Feature Coming Soon!");
}
private void showInfoAlert(String message) {
Alert alert = new Alert(Alert.AlertType.INFORMATION);
alert.setTitle("Information");
alert.setHeaderText(null);
alert.setContentText(message);
alert.showAndWait();
}
}
MainApp.java
package com.campus.eventmanagement;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class MainApp extends Application {
@Override
public void start(Stage primaryStage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("/Main.fxml"));
primaryStage.setTitle("Campus Event Management System");
primaryStage.setScene(new Scene(root));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Step 5: Build and Run
- Make sure your JavaFX libraries are properly set up in your IDE.
- Run the Spring Boot backend by executing
MainApp.java to start the JavaFX UI.
Summary
This code provides a comprehensive backend using Spring Boot and a basic frontend using JavaFX. The backend includes CRUD operations for users and events, while the frontend includes basic JavaFX layout and event handlers.
