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" ...
