Demo Spring Boot Restful API 💻

Description

This is my first project using Java and Spring Boot, where I explore building a simple RESTful API. The project demonstrates foundational concepts such as database integration, entity management, and REST endpoints.

Project Features

• CRUD operations for managing data in a MySQL database.
• RESTful API endpoints built using Spring Web.
• Integration with JPA for database interaction.
• Hot reload support with Spring DevTools.

---

Technologies and Tools

• Java Version: 17
• Spring Boot Version: 3.3.6
• Build Tool: Maven
• Database: MySQL(via XAMPP)

---

Dependencies

The project uses the following Spring Boot dependencies:

• MySQL Driver: For connecting the application to a MySQL database.
• Spring Data JPA: To simplify database operations and ORM integration.
• Spring Web: For creating RESTful APIs.
• Spring DevTools: To support live reload and faster development.

Setup Instructions

1. Clone the Repository

   git clone https://github.com/PunMung-66/demorestapi.git
   cd demorestapi

2. Configure Database
   Update the application.properties file located in src/main/resources with your MySQL database credentials:

    spring.application.name=demorestapi
    spring.datasource.url=jdbc:mysql://localhost:3306/userdb
    spring.datasource.username=root
    spring.datasource.password=
    spring.jpa.hibernate.ddl-auto=update
    spring.jpa.show-sql: true

3. Run the Application
   Run the application using the following Maven command:

   mvn spring-boot:run

4. Access the API
   The application will start on http://localhost:8080. Use tools like Postman or a browser to interact with the endpoints.
