hello good people i’m developping an application where all the pojos are exposed as interface but we map the real implementation class.we are using spring and JPA annotation.i’m about to test the one-to-one relationship and i’m having a light problem with the interface.<\/p>\n

@OneToOne or @ManyToOne on com.mycompany.project.subproject.model.UserAccountImpl.profile references an unknown entity: com.mycompany.project.<\/p>\n<\/blockquote>\n

so before this class all the other mapped class are working as expected so i’ll only post part of the applicationContext<\/code> file that i named model-config.xml<\/code><\/p>\n

here are the two involved class UserProfileImpl.java<\/code> and UserAccountImpl.java<\/code><\/p>\n
\/\/UserAccountImpl Class\n@Entity\n@Table(name =\"USER_ACCOUNT\")\npublic class UserAccountImpl implements UserAccount {\n\n  @Id @GeneratedValue\n  @Column(name=\"USER_ACCOUNT_ID\")\n  private Long ID;\n\n  ...\n\n  @OneToOne\n  @JoinColumn(name=\"USER_PROFILE_ID\")\n  private UserProfile profile;\n\n  ...\n }\n\n\/\/UserProfileImpl class\n@Entity\n@Table(name=\"USER_PROFILE\")\npublic class UserProfileImpl implements UserProfile {\n\n @Id @GeneratedValue\n @Column(name=\"USER_PROFILE_ID\")\n private Long ID;\n ....\n\n @OneToOne(mappedBy=\"profile\")\n private UserAccount userAccount;\n ....\n<\/code><\/pre>\n
}<\/p>\n
i’m still not very confortable with hibernate yet so i’m wondering if i should Change the UserProfile<\/code> reference in UserAccountImpl<\/code> to UserProfileImpl<\/code>.Then again the same can happen in the UserProfileImpl<\/code> for userAccount<\/code> reference since it’s a bidirectional navigation stuff. What’s the best option that will no break the consistency of the structure? Thanks for reading this<\/p>\n","protected":false},"excerpt":{"rendered":"
