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.

Persisting List

List is an interface provided by Java and accessed from java.util.List that has the capability to store a sequence of elements, allow duplicate elements, and contain elements of the same type. Some classes that implement the List interface are java.util.ArrayList, java.util.LinkedList, and so on. Now, let's look at how to use List while using hibernate.

Getting ready

Here, we consider a new table structure for employee, and each employee has multiple e-mail addresses. So, we create an Employee class that has the List<String> field e-mails called list of e-mail addresses. Here, we use the List class for this recipe. To achieve this, we need to create classes and tables; so, first of all, let's meet the basic prerequisites.

Creating tables

Use the following script to create the tables, unless you are using hbm2dll=create|update to dynamically create the table using hibernate.

Use the following code to create the employee table:

CREATE TABLE `employee` (
  `id` BIGINT(20) NOT...
