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.

One-to-many mapping or many-to-one mapping


Here, we will create a different scenario for a better understanding of the relationship. We will take a look at the use of both one-to-many and many-to-one relationships in a single example.

Now, we will create a relationship between actor and movie tables, where one actor is associated with one movie, but one movie can be associated with multiple actors.

Getting ready

We will create the classes and tables for Movie and Actor.

Creating the tables

Use the following script to create the tables if you are not using hbm2dll=create|update:

Use the following script to create the movie table:

CREATE TABLE `movie` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
)

Use the following script to create the actor table:

CREATE TABLE `actor` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `actorname` varchar(255) DEFAULT NULL,
  `movie_id` bigint(20) DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `FK_MOVIE_ID` (`movie_id...
