Question

我有两个班级：

@Entity
@Table(name="profil")
public class Profil {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="id")
    private long id;


    @OneToOne(mappedBy="profil")
    private Avatar avatar;

+ getters and setters
    }

和

@Entity
@Table(name="avatar")
public class Avatar {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="id")
    private Long id;


    @OneToOne(cascade = CascadeType.ALL)
    @JoinColumn(name="profil_id")
    private Profil profil;
+getters and setters
}

但是当我启动服务器时出现以下错误：引起：org.hibernate.AnnotationException：未知的mappedBy in：com.startup.app.models.entities.Profil.avatar，引用的属性unknown：com.startup.app.models.entities.Avatar.profil 在org.hibernate.cfg.OneToOneSecondPass.doSecondPass（OneToOneSecondPass.java:153）在org.hibernate.cfg.Configuration.originalSecondPassCompile（Configuration.java:1639）在org.hibernate.cfg.Configuration.secondPassCompile（Configuration.java:1393）在org.hibernate.cfg.Configuration.buildSessionFactory（Configuration.java:1784）在org.hibernate.cfg.Configuration.buildSessionFactory（Configuration.java:1868）在org.springframework.orm.hibernate4.LocalSessionFactoryBuilder.buildSessionFactory（LocalSessionFactoryBuilder.java:247）在org.springframework.orm.hibernate4.LocalSessionFactoryBean.buildSessionFactory（LocalSessionFactoryBean.java:373）在org.springframework.orm.hibernate4.LocalSessionFactoryBean.afterPropertiesSet（LocalSessionFactoryBean.java:358）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods（AbstractAutowireCapableBeanFactory.java:1541）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean（AbstractAutowireCapableBeanFactory.java:1479） ......还有126个

这是Hibernate中的一个错误，请参阅此处的说明 - HHH-5695。它与4.2.2中的错误HHH-6813一起修复。尝试升级到该版本，看看问题是否仍然存在。

Hibernate引起：org.hibernate.AnnotationException：未知的mappedBy
