如何将不是实体的类的值提供给Spring数据中的存储库

Question

I have a doubt about Spring Data and Spring Repositories. I need to provide some values to a CrudRepository from another class which is not an Entity. For example: I Have a class

@Entity
class Profile {
   private String id;
   private String name;
   private long birthDate;
   private String aboutMe;
   ...
}

and

class MyProfile {
   private String profileId;
   private String accountId;
   private String name;
   private String aboutMe;
}

and a Repository

@Transactional
@EnableTransactionManagement
@Repository
public interface ProfileRepository extends CrudRepository<Profile, String>{

    @Transactional
    Profile findByAccountId(String id);

    void updateMyProfile(MyProfile myProfile);
}

and I would like to update only some fields from Profile using data provided in MyProfile. There is a way to do this?

Thanks!!

You will have to write the update query manually:

@Query("UPDATE Profile p" +
        " SET " +
        " p.name = ?#{#myprofile.name}, " +
        " p.aboutMe = ?#{#myprofile.aboutMe}" +
        " p.account.id = ?#{#myprofile.accountId}" + // I assume that account is another entity
        " WHERE p.id = ?#{#myprofile.profileId}")
@Transactional
@Modifying
void updateMyProfile(@Param("myprofile") MyProfile myprofile);
