なぜ私の休止状態の関係は機能しませんか？

関係で私のクラスを参照してください：なぜ私の休止状態の関係は機能しませんか？

@Entity 
@Table(name = "t_aquarium") 
public class UserPoissonDO { 
    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    @Column(name = "id") 
    private Integer id; 
    @ManyToOne(cascade = { CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH }) 
    private User user; 
    @ManyToOne(cascade = { CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH }) 
    private PoissonDO poissonDO; 

    public Integer getId() { 
     return id; 
    } 

    public void setId(Integer id) { 
     this.id = id; 
    } 

    public User getUser() { 
     return user; 
    } 

    public void setUser(User user) { 
     this.user = user; 
    } 

    public PoissonDO getPoissonDO() { 
     return poissonDO; 
    } 

    public void setPoissonDO(PoissonDO poissonDO) { 
     this.poissonDO = poissonDO; 
    } 
}

私はJPAと私のBDDでそれを保存すると、私は次のエラーました：、私はUserPoissonDOオブジェクトを保存するために私のデータベースで

detached entity passed to persist: com.javaquarium.beans.data.PoissonDO; 
nested exception is org.hibernate.PersistentObjectException: detached entity 
passed to persist: com.javaquarium.beans.data.PoissonDO

が好き利用者と魚の種別に関連して

UserPoissonは1人のユーザーに関連付けられ、1人のユーザーは複数のFishを持つことができます。

私の関係は悪いと思っています。私はこれを例にしています。

EDIT： UserPoissonDO

@Service 
public class PoissonUserService implements IPoissonUserService { 
private final Logger logger = LoggerFactory.getLogger(this.getClass()); 
private UserRepository userRepository; 
private PoissonUserRepository poissonUserRepository; 

public PoissonUserService(PoissonUserRepository poissonUserRepository,UserRepository userRepository) { 
    this.poissonUserRepository = poissonUserRepository; 
    this.userRepository = userRepository; 
} 

@Override 
public List<UserPoissonDO> getUserPoissons(String username) { 
    logger.warn("Pram USER : " + userRepository.getClass().getSimpleName()); 
    User user = userRepository.findByusername(username); 
    logger.warn("USER : " + user.getUsername()); 
    List<UserPoissonDO> lstUserPoissons = new ArrayList<>(); 
    lstUserPoissons = poissonUserRepository.findByUser(user); 
    return lstUserPoissons; 
} 

@Override 
public void save(UserPoissonDO userPoissonDO) { 
    poissonUserRepository.save(userPoissonDO); 
} 

@Override 
public void save(List<UserPoissonDO> userPoissonDOList) { 
    poissonUserRepository.save(userPoissonDOList); 
} 

@Override 
public void deleteUserPoisson(List<UserPoissonDO> userPoissonDOList) { 
    poissonUserRepository.delete(userPoissonDOList); 
} 

@Override 
public void deleteUserPoisson(UserPoissonDO userPoissonDO) { 
    poissonUserRepository.delete(userPoissonDO); 
} 
} 

Controller for save UserPoissonDO : 
@Controller 
public class SaveAquariumAction { 

@Autowired 
private PoissonUserRepository poissonUserRepository; 
@Autowired private UserRepository userRepository; 
private IPoissonService poissonService; 
private IPoissonUserService poissonUserService; 
private final Logger logger = LoggerFactory.getLogger(this.getClass()); 
private List<UserPoissonDO> userPoissonDOS; 
private UserDetails userDetails; 

@RequestMapping("/SaveAquarium") 
public String listerEspeces(Model model, HttpSession session) { 
    userPoissonDOS = (ArrayList)session.getAttribute("userPoissonDOS"); 
    poissonUserService = new PoissonUserService(poissonUserRepository,userRepository); 
    logger.warn("SAVE : " + userPoissonDOS.get(0).getPoissonDO().getId() + " USER ID " + userPoissonDOS.get(0).getUser().getId()); 
    poissonUserService.save(userPoissonDOS); 
    return "redirect:/listerEspeces"; 
} 
}

あなたはUserPoissonDOまたは私のPoissonDOとUserオブジェクトのIDについて話しますか？私のIDはObject UserとPoissonDOで正しく設定されていますが、私のUserPoissonDOにはIDはありません。 – QuentinV

リレーションシップマッピングが正常に表示されます。 UserPoissonDOエンティティを永続化する方法の小さな例を提供してください。私はそこに問題があると思う。 –

私は解決策がここで提供信じる：Spring data jpa detached entityを、また、このような状況のために働くだろう。

UserPoissonDOは新しいオブジェクトですが、そのPoissonDOは切り離されています。 Springは新しいオブジェクトであるためUserPoissonDOを永続化しようとしますが、PoissonDOを既存の永続コンテキストにマージして管理する必要があるかどうかはわかりません。あなたはCascadeType.PERSISTが動作する取り外し、PoissonDOが個別に保存または既に存在するであろうことを保証することができる場合
