Description

Hibernate is the most popular Java ORM framework.  Almost every Real World Project today uses JPA and Hibernate in combination with Spring Boot and Spring Data JPA.

Do you want to Learn JPA & Hibernate and use them in combination with Spring Boot and Spring Data JPA?  Do you want to Learn about Entities, Relationships, Entity Manager, JPQL, Native Queries, Inheritance Hierarchies, Criteria API, Transaction Management, Caching and Performance Tuning with JPA & Hibernate in combination with Spring Data JPA and Spring Data REST? 

WHAT OUR LEARNERS ARE SAYING:

5 STARS - I really loved this course. The instructor explains features of JPA and Hibernate clearly and also very deeply. Especially I liked explanation of the transaction management what I didn't seen in other courses.By the way this course helped me to develop the persistence layer of a commercial application for my customer.

5 STARS - Absolute brilliant course, I was struggling using books but this course helped me understand using code to demonstrate how Hibernate and JPA work. Each video builds on the next and is at a pace that does not overwhelm you. I thoroughly recommend this course if you need to improve your Hibernate and JPA knowledge.

5 STARS - It is really state of the art and how spring boot and hibernate are used nowadays! This course was very helpful in my new job, since in the project we use spring boot and hibernate. Thank you!

5 STARS - This course exceeded my expectations, I thought I knew about hibernate but I discovered I didn't, I really recommend this course.

5 STARS - Thanks Ranga for the wonderful course on Hibernate and JPA with Spring Boot! It's a long course and well worth it. Keep up the great work!

COURSE OVERVIEW

Hibernate is the most popular implementation of JPA. It was the most popular ORM framework option before JPA emerged and it provides additional features on top of JPA. We will use Hibernate as the JPA implementation in this course.

The Java Persistence API provides Java developers with an api for mapping java objects to relational data. In this course, you will learn about the Hibernate, JPA API, JPQL (Java Persistence query language), Java Persistence Criteria API and how you can perform ORM (Object Relational Mapping) with JPA and Hibernate.
