Lombok @Builder and JPA Default constructor

Question

I\'m using project Lombok together with Spring Data JPA. Is there any way to connect Lombok @Builder with JPA default constructor?

Code:

Answer 1

To use the following combination

• lombok
• JPA
  • CRUD
  • proper @EqualsAndHashCode
• immutability - public final fields
• no getters
• no setters
• changes via @Builder and @With

I used:

//Lombok & JPA
//https://stackoverflow.com/questions/34241718/lombok-builder-and-jpa-default-constructor

//Mandatory in conjunction with JPA: an equal based on fields is not desired
@lombok.EqualsAndHashCode(onlyExplicitlyIncluded = true)
//Mandatory in conjunction with JPA: force is needed to generate default values for final fields, that will be overriden by JPA
@lombok.NoArgsConstructor(access = AccessLevel.PRIVATE, force = true)
//Hides the constructor to force usage of the Builder.
@lombok.AllArgsConstructor(access = AccessLevel.PRIVATE)
@lombok.ToString
//Good to just modify some values
@lombok.With
//Mandatory in conjunction with JPA: Some suggest that the Builder should be above Entity - https://stackoverflow.com/a/52048267/99248
//Good to be used to modify all values
@lombok.Builder(toBuilder = true)
//final fields needed for imutability, the default access to public - since are final is safe 
@lombok.experimental.FieldDefaults(makeFinal = true, level = AccessLevel.PUBLIC)
//no getters and setters
@lombok.Getter(value = AccessLevel.NONE)
@lombok.Setter(value = AccessLevel.NONE)

//JPA
@javax.persistence.Entity
@javax.persistence.Table(name = "PERSON_WITH_MOTTO")
//jpa should use field access 
@javax.persistence.Access(AccessType.FIELD)
public class Person {
  @javax.persistence.Id
  @javax.persistence.GeneratedValue
  //Used also automatically as JPA
  @lombok.EqualsAndHashCode.Include
  Long id;
  String name;
  String motto;
}
