Clone the backend project to your local machine:

git clone <your-repository-url>
cd <your-repository-directory>

Step 2: Configure the Application

Make sure to configure your application.properties or application.yml file with your database credentials.

spring.datasource.url=jdbc:mysql://localhost:3306/your_database_name
spring.datasource.username=your_username
spring.datasource.password=your_password
spring.jpa.hibernate.ddl-auto=update

The command line of launching MySQL:

& "C:\Program Files\MySQL\MySQL Server 8.0\bin\mysql" -u root -p

Step 3: Get your ebay API token

Please follow the official instruction: https://developer.ebay.com/develop/get-started

Step 4: launch the server

To start the backend server, run the following command in your terminal:

./mvnw spring-boot:run

Testing the APIs with Postman

All API endpoints can be found in the OnlineStore\src\main\java\OnlineStore\controller folder and can be tested via Postman directly.
Please note that the backend, configured with Spring Boot, runs on port 8080 by default.
