Lombok project

JUG LvivJUG Lviv

If you tired of writing get/set or equals/hashcode methods you can try Lombok. It’s a cute project which provides several useful annotations  like

@Getter / @Setter

Never write public int getFoo() {return foo;} again.
@Getter(lazy=true)
Laziness is a virtue!
@ToString
No need to start a debugger to see your fields: Just let lombok generate a toString for you!
@EqualsAndHashCode
Generates hashCode and equals implementations from the fields of your object.

and many others.

With Lombok your class will look like
01 import lombok.ToString;
02 
03 @ToString(exclude=“id”)
04 public class ToStringExample {
05   private static final int STATIC_VAR = 10;
06   @Getter @Setter(AccessLevel.PROTECTED) private String name;
07   @Getter @Setter  private int id;
08   
09 }

    Not so obvious.
    In new version it is impossible to set @Getter or @Setter on fields which also needs other annotations on field's getter or setter methods. So, you'll get perfect spagetti where some fields would have annotated getters and other strictly defined…

    Have a nice coding!

  • It's good choice for some routine classes like dto but obviously it can provoke issue on jpa entity. So sometime it is useful sometime not.
