# 🌐📡 Spring Boot Rest-API

## 🌱 What is Spring Boot REST API?

A Spring Boot REST API is a web service built using Spring Boot, a Java-based framework that simplifies the development of stand-alone, production-grade Spring applications. REST (Representational State Transfer) is a popular architectural style for building web services that communicate over HTTP using standard methods like GET, POST, PUT, and DELETE.

# 🚀 Spring Boot REST API Example

This project demonstrates a complete **Spring Boot REST API** using:

- **Spring MVC**

- **Spring Boot 3**

- **Spring Data JPA**

- **Hibernate**

- **MySQL Database**

- **Maven**

- **Postman** for API testing

- **MVC architecture**

---

## 🧰 Technologies Used

| Technology | Purpose |

|------------|---------|

| **Spring Boot** | Framework to quickly build RESTful APIs |

| **Spring MVC** | Handles HTTP requests via controllers |

| **JPA (Java Persistence API)** | ORM specification to interact with databases |

| **Hibernate** | Implementation of JPA |

| **MySQL** | Relational database used for data storage |

| **Postman** | API client for testing endpoints |

| **REST API** | Architectural style for building web services |

---

## 🌐 What is a REST API?

A **REST API** (Representational State Transfer) allows applications to communicate via HTTP using standard methods:

- `GET` → Retrieve data  

- `POST` → Create new data  

- `PUT` → Update existing data  

- `DELETE` → Remove data

All data is exchanged in **JSON** format.

---

## 🏗️ Project Architecture (MVC Pattern)

The application follows the **Model-View-Controller (MVC)** architecture:

- **Model** – Represents application data (e.g., User, Product)

- **View** – Not used directly; API returns JSON responses

- **Controller** – Handles incoming HTTP requests and routes them to the correct service

- **Service** – Contains the business logic

- **Repository** – Communicates with the database using JPA

## ⚙️ MySQL Configuration (application.properties)

Update the following in your `application.properties`:

- Database URL

- Username & Password

- Hibernate dialect

- DDL auto mode (e.g., `update`, `create`, `validate`)

---

## 🧪 API Testing with Postman

| Method | Endpoint | Description | Body (JSON) |

|--------|----------|-------------|-------------|

| `GET` | `/api/users` | Fetch all users | – |

| `POST` | `/api/users` | Create a new user | `{ "name": "John", "email": "[email protected]" }` |

| `DELETE` | `/api/users/{id}` | Delete a user by ID | – |

Use **Postman** or **cURL** to interact with these endpoints after running the app.

---

## 📖 Key Concepts

| Term | Description |

|------|-------------|

| **JPA** | Java API for managing relational data via ORM |

| **Hibernate** | Popular implementation of JPA |

| **Spring Boot** | Framework for rapid application development |

| **MySQL** | Open-source relational database |

| **REST** | API style using HTTP methods for CRUD operations |

| **MVC** | Design pattern separating data, UI, and logic layers |

---

## ✅ How to Run

1. Clone the repository

2. Set up your MySQL database

3. Update the `application.properties` with DB credentials

4. Run the Spring Boot application

5. Test APIs via Postman

---

## 📦 Future Enhancements

- Add Swagger for API documentation

- Integrate Spring Security for authentication

- Dockerize the application
