相关实体将被保持为空
我是jpa和hibernate的新手，我试图坚持一个与两个实体有2个关系的bean，因为我这样做了我试图保存的实体被保存但相关实体不存在，他们留下来空第一课
@Entity
@Table(name = "MODIFICATION")
public class ModificationBE extends AbstractBE implements Serializable {
/**
*
*/
private static final long serialVersionUID = 5862456626257704084L;
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "modification_seq")
@SequenceGenerator(name = "modification_seq", sequenceName = "modification_sequence", allocationSize = 1)
@Column(name = "ID", unique = true, nullable = false)
private Long idModification;
@Relation(RelationType.ENTITY)
@OneToMany(cascade = CascadeType.MERGE, fetch = FetchType.EAGER, orphanRemoval = false)
@JoinColumn(name = "ID_Profils")
private List profils;
@Relation(RelationType.ENTITY)
@OneToOne(cascade = CascadeType.PERSIST, fetch = FetchType.EAGER)
@JoinColumn(name = "ID_Utiisateur")
private UtilisateurBE user;
第二课
@Entity
@Table(name = "Utilisateur")
public class UtilisateurBE extends AbstractBE implements Serializable {
/**
*
*/
private static final long serialVersionUID = 5192421474902029299L;
@Id
@Column(name = "ID", unique = true, nullable = false)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "user_seq")
@SequenceGenerator(name = "user_seq", sequenceName = "user_sequence", allocationSize = 1)
private Long idUtilisateur;
@Column(name = "nom")
private String nom;
@Column(name = "prenom")
private String prenom;
@Column(name = "email")
private String email;
@Enumerated(EnumType.STRING)
@Column(name = "type")
TypeUtilisateur typeUser;
@OneToOne(cascade = CascadeType.PERSIST, fetch = FetchType.LAZY)
private ModificationBE modification;
第三类/实体
@Entity
@Table(name = "PROFIL")
public class ProfilBE extends AbstractBE implements Serializable {
/**
*
*/
private static final long serialVersionUID = -4017244348063720915L;
@Id
@Column(name = "ID", unique = true, nullable = false)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "profil_seq")
@SequenceGenerator(name = "profil_seq", sequenceName = "profil_sequence", allocationSize = 1)
private Long idProfil;
@Column(name = "nom")
private String nom;
@Column(name = "prenom")
private String prenom;
@Column(name = "email")
private String email;
@Enumerated(EnumType.STRING)
@Column(name = "type")
private TypeProfil typeProfil;
@ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.DETACH)
@JoinColumn(name = "ID_Groups")
private List groups;
@Column(name = "status")
private boolean status;
我试图发布这个
{
"idModification": 1,
"profils": [
{
"idProfil": 1,
"nom": "toto",
"prenom": "ElGrande",
"email": "elGrande.toto@vero.com",
"typeProfil": "ASSOCIE",
"groups": [
{
"id": 2936,
"name": "Suivi Performance Entrepôt",
"centrale": "NORD-OUEST",
"specGroupe": null,
"privilege": "CPI et développeur"
},
{
"id": 3008,
"name": "SIDO",
"centrale": "NORD-OUEST",
"specGroupe": "Appro",
"privilege": "Expert"
}
],
"status": true
},
{
"idProfil": 1,
"nom": "tata",
"prenom": "ElGrande",
"email": "elGrande.tata@vero.com",
"typeProfil": "PDV",
"groups": [
{
"name": "SIDO",
"idGroup": 1
},
{
"name": "SIDE",
"idGroup": 2
}
],
"status": "true"
}
],
"user": {
"nom": "Lemcirdi",
"prenom": "Anas",
"email": "anas.lemcirdi@haha.com",
"typeUser": "SID",
"id": "1"
}
}
但是这个
{
"idModification": 1,
"profils": null,
"user": null
}什么被保存到我的数据库，我没有得到任何错误，所以它必须是一个映射错误。 我该如何解决它。
