具有继承和 JPA 的 Lombok @Builder

Question

我有这个class:

@Entity
@Table(name = "PERSONNE")
@Inheritance(strategy = InheritanceType.JOINED)
@NoArgsConstructor
@AllArgsConstructor
@Data
@SuperBuilder
@ToString
@EqualsAndHashCode(of = { "personneId" })
public class Personne implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @Column(name = "PERSONNE_ID")
    protected Long personneId;

}

和另一个

@Entity
    @Table(name = "DISSIDENT")
    @PrimaryKeyJoinColumn(name = "PERSONNE_ID")
    @Data
    @SuperBuilder
    @NoArgsConstructor
    @AllArgsConstructor
    @ToString(callSuper = true)
    @EqualsAndHashCode(callSuper = true)
    public class Dissident extends Personne {
    
        private static final long serialVersionUID = 1L;
    
    }

但是当我运行测试时我得到了这个错误：

java: constructor Dissident() is already defined in class com.bar.peris.model.Dissident

Answer 1

尝试更改@NoArgsConstructor 的顺序 @AllArgsConstructor。 Class 默认情况下没有参数构造函数，除非定义了构造函数。
