Banking Service Spring Boot Rest API with MySQL, JPA & Postman | Spring Boot CRUD Operations in Java
💳 Build a Complete Spring Boot 3 Banking Service API with MySQL, JPA & Postman | Full CRUD Operations
In this video, we’ll build a real-world Banking Service REST API using Spring Boot 3, Java 17, Spring Data JPA, and MySQL. You’ll learn how to set up the project, design a layered architecture, and implement full CRUD operations along with transaction-based features like deposit, withdrawal, and fund transfer.
By the end, you’ll have a production-ready backend project you can showcase in interviews or use as a base for more complex applications.
