Master Microservices with Spring Boot and Spring Cloud - Step 17 – Create a JPA Repository

The video tutorial explains how to use data from an in-memory database to create a currency exchange service. It covers creating a repository interface using JPA, implementing query methods to search data by currency, and integrating these methods into a controller. The tutorial concludes with testing the service and preparing for the next steps in developing a currency conversion service.

What is the role of Spring Data JPA in the context of query methods?

• It handles data encryption

• It provides a user interface

• It automatically implements query methods

• It manages database connections
