【问题描述】:
我已经测试了 2 天来解决这个问题,但没有任何效果。 我在双向关系中暗示了这些实体。
@Entity
@Table( name = "T_user" )
public class T_user implements Serializable {
@Id
@GeneratedValue( strategy = GenerationType.IDENTITY )
private Long id_user;
@OneToOne( targetEntity = T_infosProfile.class, mappedBy = "user", fetch = FetchType.LAZY, orphanRemoval = true )
private T_infosProfile infosProfile;
public void setInfosProfile( T_infosProfile infosProfile ) {
this.infosProfile = infosProfile;
}
}
和
@Entity
@Table( name = "T_infosProfile" )
public class T_infosProfile {
@Id
@GeneratedValue( strategy = GenerationType.IDENTITY )
private Long id_infos;
@OneToOne( targetEntity = T_user.class, fetch = FetchType.LAZY )
@JoinColumn( name = "id_user", unique = true, nullable = false )
private T_user user;
@Column( name = "pourcentage_completion", length = 3, updatable = true, unique = false )
private Integer pourcentageCompletion;
@Column( name = "infos_identite", nullable = false, updatable = true, length = 1, columnDefinition = "TINYINT(1)" )
private Boolean infosIdentiteCompleted;
@Column( name = "infos_coordonnees", nullable = false, updatable = true, length = 1, columnDefinition = "TINYINT(1)" )
private Boolean infosCoordonneesCompleted;
@Column( name = "infos_bancaires", nullable = false, updatable = true, length = 1, columnDefinition = "TINYINT(1)" )
private Boolean infosBancaireCompleted;
@Column( name = "infos_chicowa", nullable = false, updatable = true, length = 1, columnDefinition = "TINYINT(1)" )
private Boolean infosCompleted;
//the setter method
public void setUser( T_user user) {
this.user = user;
this.infosIdentiteCompleted = true;
this.pourcentageCompletion = 0;
this.infosCoordonneesCompleted = this.user.getInfosCoordonnees() == null ? false : true;
this.infosBancaireCompleted = this.user.getInfosBancaire() == null ? false : true;
this.infosCompleted = this.user.getInfosCompleted() == null ? false : true;
if ( this.infosCoordonneesCompleted == true ) {
this.pourcentageCompletion = 50;
}
if ( this.infosBancaireCompleted == true && this.pourcentageCompletion == 50 ) {
this.pourcentageCompletion = 75;
}
if ( this.infosChicowaCompleted == true && this.pourcentageCompletion == 75 ) {
this.pourcentageCompletion = 100;
}
}
}
我也有这个方法用来更新用户的 infosProfile :
@Service
public class UIServiceImpl implements UIService {
@Autowired
private TinfosProfileRepository infosProfileRepository;
@Override
public T_infosProfile saveInfosPorfile( T_user connectedUser ){
T_infosProfile infosProfile = connectedUser.getInfosProfile();
infosProfile.setUser( connectedUser );
connectedUser.setInfosProfile( infosProfile );
try {
return infosProfileRepository.save( infosProfile );
} catch ( Exception e ) {
throw new ExceptionsDAO( e.getMessage() );
}
}
但是当我调用此方法时,它适用于一种情况,但对于另一种情况,我得到了这个异常:
10-04-2017 16:27:43 [http-nio-8080-exec-3] WARN o.h.e.jdbc.spi.SqlExceptionHelper - SQL Error: 1062, SQLState: 23000
10-04-2017 16:27:43 [http-nio-8080-exec-3] ERROR o.h.e.jdbc.spi.SqlExceptionHelper - Duplicate entry '8' for key 'UK_bkariaocmnn2rlh477hvoqkyf'
我只想更新当前用户的 infosProfile 属性。 它工作正常的情况是只更新了一个 infosProfile 的属性,但是当我同时更新 2 个属性并尝试 saveInfosProfile() 时,会引发异常。
请帮忙。
