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 Array


Working with Array is similar to that with List, but in List, it is not compulsory to add @IndexColumn. However, Array requires an indexed column to maintain the column order.

Getting ready

Create the required class using the following code to persist Array:

Source file: Employee.java

@Entity
@Table(name = "employee")
public class Employee {

  @Id
  @GeneratedValue
  @Column (name = "id")
  private long id;

  @Column (name = "name")
  private String name;

  @ElementCollection
  @IndexColumn(name="email_index")
  @CollectionTable(name = "email")
  private String[] emails;

  public long getId() {
    return id;
  }

  public void setId(long id) {
    this.id = id;
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public String[] getEmails() {
    return emails;
  }

  public void setEmails(String[] emails) {
    this.emails = emails;
  }

  @Override
  public String toString() {
    return "Employee" ...
