Java Hibernate Cookbook

Overview of this book

This book will provide a useful hands-on guide to Hibernate to accomplish the development of a real-time Hibernate application. We will start with the basics of Hibernate, which include setting up Hibernate – the pre-requisites and multiple ways of configuring Hibernate using Java. We will then dive deep into the fundamentals of Hibernate such as SessionFactory, session, criteria, working with objects and criteria. This will help a developer have a better understanding of how Hibernate works and what needs to be done to run a Hibernate application. Moving on, we will learn how to work with annotations, associations and collections. In the final chapters, we will see explore querying, advanced Hibernate concepts and integration with other frameworks.

Introduction

Hibernate supports some advanced features, such as caching, inheritance, versioning, maintaining a history of objects, interceptor, batch processing, and many more.

Here, you will learn the first-level, second-level, and query caches, in detail and with an example, to see how to cache particular objects and how caching works. Apart from this, you will also learn a useful feature of hibernate called inheritance, which hibernate provides as a facility to be applied on the database side. You will learn three major inheritance types in this chapter. We will also will look into versioning, maintaining a history of data or of an object for a sensitive application, and at last, how to intercept hibernate's processing and how to perform batch processing using hibernate.
