This repository contains a single Spring Boot Maven application in the demo/ folder. The project already has the standard package layout for a product-based CRUD app, with domain, repository, and service layers in place.

Overview

The application currently includes:

• a Spring Boot entry point
• a Product JPA entity
• a ProductRepository based on Spring Data JPA
• a ProductService interface and service implementation
• a test class for basic Spring context loading

The controller file exists, but it is currently empty, so the REST API surface is not implemented yet.

Tech Stack

• Java 17 JDK
• Spring Boot 4.0.3
• Spring Web
• Spring Data JPA
• Maven Wrapper

Loading

Source Layout

• demo/src/main/java/com/example/demo contains the application source code.
• demo/src/main/resources contains runtime configuration.
• demo/src/test/java/com/example/demo contains tests.
• demo/target contains generated Maven build output.

Current Status

The repository is structured like a layered Spring Boot application, but it is not yet a complete end-to-end CRUD app.

• ProductController.java exists but does not currently define endpoints.
• application.properties only sets the application name.
• pom.xml includes JPA support, but the project does not currently declare a database driver.

Working With The Project

From the demo/ directory you can use the Maven wrapper:

.\mvnw.cmd test

This requires a Java 17 JDK. A plain JRE is not enough because Maven needs the Java compiler.

If you want to run the application as a real database-backed API, the next missing pieces are:

1. add a database driver dependency
2. configure a datasource in application.properties
3. implement REST endpoints in ProductController.java
