Overview of this book

Hibernate has been so successful since its inception that it even influenced the Java Enterprise Edition specification in that the Java Persistence API was dramatically changed to do it the Hibernate way. Hibernate is the tool that solves the complex problem of Object Relational Mapping. It can be used in both Java Enterprise applications as well as .Net applications. Additionally, it can be used for both SQL and NoSQL data stores. Some developers learn the basics of Hibernate and hit the ground quickly. But when demands go beyond the basics, they take a reactive approach instead of learning the fundamentals and core concepts. However, the secret to success for any good developer is knowing and understanding the tools at your disposal. It’s time to learn about your tool to use it better This book first explores the internals of Hibernate by discussing what occurs inside a Hibernate session and how Entities are managed. Then, we cover core topics such as mapping, querying, caching, and we demonstrate how to use a wide range of very useful annotations. Additionally, you will learn how to create event listeners or interceptors utilizing the improved architecture in the latest version of Hibernate.

Summary


We demonstrated many annotations and why and how they are used. The previous chapter covered mapping concepts; we continued that discussion in this chapter by looking at annotations that help us create better object/relational mapping. We also looked at annotations that impact the behavior of an entity. Finally, we looked at annotations that modify the SQL statement that is composed by Hibernate.

As mentioned earlier, we will use mostly annotations in this book, whenever possible. In the next chapter, we will explore various ways of fetching the data from the database and discuss different strategies.
