How to use @EqualsAndHashCode With Include - Lombok

Question

How to use @EqualsAndHashCode With Include, Lombok library for Java.

@EqualsAndHashCode.Include( )

How to make Equal

Answer 1

From Lombok, Just add the @EqualsAndHashCode.Include or @EqualsAndHashCode.Exclude on required fields

Any class definition may be annotated with @EqualsAndHashCode to let lombok generate implementations of the equals(Object other) and hashCode() methods. By default, it'll use all non-static, non-transient fields, but you can modify which fields are used (and even specify that the output of various methods is to be used) by marking type members with @EqualsAndHashCode.Include or @EqualsAndHashCode.Exclude. Alternatively, you can specify exactly which fields or methods you wish to be used by marking them with @EqualsAndHashCode.Include and using @EqualsAndHashCode(onlyExplicitlyIncluded = true).

@EqualsAndHashCode
@Table(name = "USER")
public class User
  {

  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  @Column(name = "IDENTITY_USER")
  @EqualsAndHashCode.Include
  private Long identity;
 }
