Spring Data JPA + EclipseLink: Configuring Spring-Boot to use EclipseLink as the JPA provider

Source code for tutorial published on https://blog.marcnuri.com/spring-data-jpa-eclipselink-configuring-spring-boot-to-use-eclipselink-as-the-jpa-provider/

Simple Spring Boot application that uses EclipseLink as the JPA provider (see CustomJpaConfiguraton).

To run the application:

$ ./gradlew bootRun

Once the application is running you can test the provided endpoints:

$ curl -s localhost:8080/mounts | jq
