Simple Spring Boot CRUD Application

I'll create a basic Spring Boot application that performs CRUD operations for a "Task Manager" with a simple HTML, CSS, and JavaScript frontend.

How to Run the Application

1. Make sure you have Java 17 and Maven installed on your system
2. Clone or download the project
3. Navigate to the project directory in your terminal

4. Run the application using Maven:

   mvn spring-boot:run
5. Open your browser and go to http://localhost:8080

Project Structure

• Backend (Spring Boot):

  • TaskManagerApplication.java: Main application class
  • Task.java: Model class for tasks
  • TaskService.java: Service for task operations (using in-memory storage)
  • TaskController.java: REST controller for CRUD operations
  • WebConfig.java: Configuration for CORS

• Frontend (HTML/CSS/JavaScript):

  • index.html: Main page with form and task list
  • style.css: Styling for the application
  • script.js: JavaScript for interacting with the backend API

Features

• Create new tasks with title, description, and completion status
• View all tasks in a list
• Update existing tasks
• Delete tasks
• Simple and responsive UI

This is a very basic implementation that demonstrates CRUD operations with Spring Boot and a simple frontend. The application uses in-memory storage (a HashMap) instead of a database for simplicity.
