Library-API Project 📚

This project is a simple Spring Boot application that provides a RESTful API for managing books. It allows users to perform CRUD (Create, Read, Update, Delete) operations on books using the API. It adding new books, updating existing ones, searching for books, and deleting books.

Project Structure 📂

The project consists of several components, each serving a specific purpose:

1. Controller: Defines the RESTful endpoints for handling book-related requests. It interacts with the Service to perform various operations.

2. Service: Contains the business logic for book-related operations. It interacts with the DAO to access the database.

3. DAO: Provides access to the database using Spring Data JPA. It extends the JpaRepository interface to enable CRUD operations.

4. Entities: Represents the entity (model) for a book. It is annotated with @Entity to indicate it's a JPA entity and corresponds to a database table.
