I am trying to do something similar like below.
@Entity
@Table(name="Sample")
public record Sample(Integer id, String name) {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name="user_id")
private Integer id;
@Column(name="username")
private String name;
}
However, it gives me error "User declared non-static fields id are not permitted in a record" and same for name field as well.
Is there a way to use new java feature "record" with JPA annotation?
CodePudding user response:
See the article, Using Records as Projections in JPA by Billy Korando. The following is a brief summary.
Records cannot be Entities
JPA implementations such as Hibernate depend on features either forbidden or not recommended by the JEP 395: Records spec: no-arg constructors, non-final fields, setters, etc.
Other uses of records
You can use records with:
CriteriaBuilderTypedQueryNativeQuery- Mapping definition
Spring data has some support as well.
See that article linked above for details, and for links to two other articles.
