Banking Movements REST API - Java/Spring/OAuth2

Java/Spring Boot REST API project focused on secure banking movement retrieval using OAuth2/token-based authentication.

This is an academic/backend practice project that demonstrates REST API design, Spring Boot configuration, persistence setup, and authentication-oriented API behavior.

What this demonstrates

• REST API design with Spring Boot
• OAuth2/resource-server-oriented security setup
• Backend service structure for banking movement retrieval
• Database-backed API behavior with JPA
• H2/MySQL-compatible persistence configuration
• Postman collection usage for manual/API validation

Tech stack

• Java 11
• Spring Boot 2.6.x
• Spring Web
• Spring Data JPA
• Spring Security OAuth2 client/resource server dependencies
• H2 / MySQL driver
• Maven
• Postman collection

Project context

This repo was created as a backend/API learning project. It is useful as a compact example of Spring Boot API structure, authentication-oriented configuration, and banking-domain endpoint modeling.

Naming note

The original repository name is OAuth2-Bancary-movements. The intended English wording is Banking Movements REST API.
