'How to save without using autogenerated in JPA?

I am using oracle database with JPA, I have an id column this is not auto generated type. While performing saveAll() operation we are getting - ids for this class must be manually assigned before calling save(): This is Id i am getting form some other table

@Entity
@Table(name = "area_usr")
public class AreaUsr {

    @Id
    private Integer usrId;
    private String area;
    //getter setter
}

List<AreaUsr> au = xyzRepo.getAreaInfo();
areaUsrRepo.saveAll(au); // here i am getting the error
javaspring-bootspring-data-jpa


Solution 1:[1]

Because ids can't be null ,and since it's not auto generated ,it must be specified before getting persisted.
