E-Commerce Web Application

This project is a backend implementation of an e-commerce web application built using the Java Spring Boot framework. The application allows users to retrieve product information from a database and enables sellers to update product details.

Features

• Retrieve a list of products available in the database.
• Sellers can update the details of a specific product.
• Backend services that handle CRUD operations for product management.

Technologies Used

• Java Spring Boot: Framework for building the backend REST API.
• PostgreSQL: Database system used to store product details.
• Hibernate: Object-Relational Mapping (ORM) framework to map Java objects to database tables.
• Apache Tomcat: Server for hosting and running the application.
• Lombok: Used to reduce boilerplate code.
• Maven: Dependency management tool for managing external libraries.

Setup Instructions

Prerequisites

• Java 11 or higher
• PostgreSQL (with a running instance)
• Maven 3.6.x or higher
• Apache Tomcat (optional, if not using embedded server)

Database Setup

1. Install PostgreSQL and create a new database for the project.

2. Update the application.properties file to configure the database connection.

   spring.datasource.url=jdbc:postgresql://localhost:5432/<your-database-name>
   spring.datasource.username=<your-username>
   spring.datasource.password=<your-password>
   spring.jpa.hibernate.ddl-auto=update

Build and Run

1. Clone the repository to your local machine:

   git clone <repository-url>
   cd E-commerce-web-Application-main

2. Build the project using Maven:

   mvn clean install

3. Run the Spring Boot application:

   mvn spring-boot:run

   The application should now be running at http://localhost:8080.

API Endpoints

The application exposes the following REST API endpoints:

• GET /products: Retrieve a list of products.
• GET /products/{id}: Retrieve product details by product ID.
• POST /products: Add a new product (Seller only).
• PUT /products/{id}: Update an existing product (Seller only).
• DELETE /products/{id}: Delete a product by ID (Seller only).

Lombok Configuration

This project uses Lombok annotations to reduce boilerplate code. Make sure to install Lombok in your IDE:

• For Eclipse, install the Lombok plugin from the Eclipse Marketplace.
• For IntelliJ IDEA, enable annotation processing under Preferences > Build, Execution, Deployment > Compiler > Annotation Processors.

Running Tests

To run the unit tests, use the following command:

mvn test
