Spring Data's mission is to provide a familiar and consistent, Spring-based programming model for data access. Spring Data JPA makes it very easy to implement JPA-based repositories. What are dirty read, non-repeatable read and phantom read? We will create a simple repository extending JPARepository and explore different methods it exposes. Spring Data JPA is a framework that extends JPA by adding an extra layer of abstraction on the top of the JPA provider. The software programs and technologies used in this tutorial are: Java 8, Apache Tomcat 9, MySQL Server 5.7, Eclipse IDE 4.7 (Oxygen), Spring framework 5.1, Hibernate framework 5.4, Spring Data JPA 2.1.5 and Servlet 3.1.
