Gallerist API: Secure Vehicle Purchase RESTful Service Development with Spring Boot

Brief Description

In this project, I developed a simple REST API focused on the vehicle purchase flow using Spring Boot. The repository description and README define the project as a vehicle purchase service operating with a local database. :contentReference[oaicite:0]{index=0}

Problem

Simply providing plain endpoints for vehicle purchase transactions is insufficient. I addressed the need to consolidate backend requirements such as authentication, data persistence, input validation, and testable documentation into a single structure. :contentReference[oaicite:1]{index=1}

Solution

I built the project on Spring Boot 3.3.5 and Java 17. For the data layer, I used PostgreSQL and Spring Data JPA; for security, Spring Security and JWT; for request validation, Spring Validation; and for API inspection and testing, the Swagger interface. The README specifies database and API key definitions via environment variables, and the endpoint testing flow is provided locally via http://localhost:8080/swagger-ui/index.html#" title="Swagger UI">Swagger UI. :contentReference[oaicite:2]{index=2}

Result

The outcome is a well-structured Spring Boot API example that integrates security, database, and documentation layers. Although it's a small repository, it consolidates the essential components required for a real backend setup within a single project. :contentReference[oaicite:3]{index=3}
