我有这个例外:

  

org.hibernate.MappingException:持久化类未知:   java.lang.Long中

我正在使用Hibernate 5.1.0.Final和spring-orm 4.2.4.RELEASE

我的春季配置文件(spring.xml):

我有两个MySQL表,UserAddress

User = Id, Name and Firstname
Address = Id, Street, City and UserId

对于我的地址entitybean中的UserId,我这样做:

@OneToOne
@JoinColumn(name="id")
public Long getIdUtilisateur() {
    return idUtilisateur;
}

1 个答案:

答案 0 :(得分:7)

您不能将非实体用作OneToOneJoinColumn的目标,就像您在此处所做的那样:

@OneToOne
@JoinColumn(name="id")
public Long getIdUtilisateur() {
    return idUtilisateur;
}

相反,您可以使用此方法映射UtilisateurAddress关系:

@OneToOne
@JoinColumn(name="id")
public Utilisateur getUtilisateur() {
    return utilisateur;
}

当然,Utilisateur应该是一个实体:

@Entity
public class Utilisateur { ... }
