Lombok 0.10.1 @Data breaks all JPA @Entity objects?

[Jacek Furmankiewicz]

I just upgrade our project from 0.9 to 0.10.1 and all our JPA/Hibernate code is failing.

it seems @Data does not generate a no-args constructor any more and thus breaks all @Entity objects.

We'd have to go through hundreds of JPA entities and add @NoArgsConstructor to all of them!

Is this a bug? Design? Can it be changed so that on @Entity objects @Data is smart enough to leave the no-args constructor?

Hi Jacek,

as far as I can tell @Data works perfectly fine.
Please note that @Data is not a shorthand for @NoArgsConstructor,
@Getter, @Setter, @EqualsAndHashCode and @ToString, but rather
@RequiredArgsConstructor, ..... and @ToString.
It would be nice, if you could add a small code example.

Here is the whole class.

 

import lombok.Data;

public @Data class Mountain {

private final String name;

private final double latitude, longitude;

private String country;

}

I am going to try it again at the house later.  I will email you in the morn and let you know if i have any luck.  thanks for the emails.

@Jacek: That is not an entity class. Entity classes must not have
final fields. As per the J2EE tutorial: "The class must not be
declared final. No methods or persistent instance variables must be
declared final."

Remove the "final" from your instance variables and it will work.

It works perfect now.  Thanks.  How come in the video on the website, they dont have to use non final variables?  Anyway, I will definitely start using lombok.

Hi,

I have the same problem, but in my case is a little diferent. I didn't
use final in my attributes I use the annotation @NotNull.
There's

There's something that I can do? Or the unique solution is stop use
the @Data and use just @Getter and @Setter?

Follow my code.

package br.com.ligdiagnosticos.scl.model.exame;

import java.util.Date;

import javax.persistence.Entity;
import javax.persistence.Inheritance;
import javax.persistence.InheritanceType;
import javax.persistence.ManyToOne;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
import javax.validation.constraints.NotNull;

import lombok.Data;
import br.com.ligdiagnosticos.scl.model.apoio.Convenio;
import br.com.ligdiagnosticos.scl.model.apoio.Medico;
import br.com.ligdiagnosticos.scl.model.apoio.Procedencia;
import br.com.ligdiagnosticos.scl.model.apoio.Usuario;
import br.com.ligdiagnosticos.scl.model.common.GenericEntity;

@Entity
@Inheritance(strategy = InheritanceType.JOINED)
public abstract @Data class Exame extends GenericEntity {

private static final long serialVersionUID = -7215894532261917873L;

@NotNull
@ManyToOne
private Amostra amostra;

@Temporal(TemporalType.DATE)
private Date dataLiberacao;

@ManyToOne
private Medico medico;

@ManyToOne
private Convenio convenio;

@ManyToOne
private Procedencia procedencia;

@ManyToOne

}
