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.

Deployment


When deploying an application that uses Hibernate, you will most likely have to perform configuration steps to complete the deployment. This is because, in various contexts, the application server or the container manages the resources that are needed for runtime. In this section, we will discuss some of those topics, and later we will see how to complete these steps in the EJB and Spring contexts, as they are different.

Note

Throughout this book, and particularly in this chapter, the terms context and container are mostly used interchangeably. These terms are used to refer to EJB, Servlet, and Spring containers. The term application server refers to the runtime platform for your Java enterprise application, for example, JBoss or WebLogic.

Configuration

In both the EJB and Spring context, it is best, and sometimes mandatory, to give the container/context manage the necessary resources. For this reason, you would need to use the context configuration files to set up resources for Hibernate...
