Welcome to the Spring Boot with Spring Data JPA tutorial! In this tutorial, we are going to see how Spring Data JPA provides complete abstraction over the DAO layer. We don’t need to write the implementation for the DAO layer anymore; Spring Data auto-generates the implementation DAO implementations.
We already had an introduction to Spring Boot, and for this tutorial, we will use Spring Boot along with Spring Data. You will also see how Spring Boot auto-configuration helps to get data source configurations done, hassle-free.
