Question

我有两个类映射到OneToMany，ManyToOne，我得到异常：

org.hibernate.AnnotationException：mappedBy引用未知的目标实体属性： entity_package.UserEntity.ownedTickets中的entity_package.TicketEntity.ownerEntity

这是代码：

公共类UserEntity实现Serializable {

@OneToMany(mappedBy="ownerEntity")
public List<TicketEntity> getOwnedTickets() {
    return tickets;
}
public void setOwnedTickets(List<TicketEntity> tickets) {
    this.tickets = tickets;
}

和......

公共类TicketEntity实现Serializable {

private UserEntity ownerEntity;

@ManyToOne
@JoinColumn(name="owner_id")
public UserEntity getOwner() {
    return ownerEntity;
}
public void setOwner(UserEntity owner) {
    this.ownerEntity = owner;
}

怎么了？

Answer 1

属性名称为owner，由带注释的getter定义。使用：

@OneToMany(mappedBy="owner")
public List<TicketEntity> getOwnedTickets() {

实体onetomany ..注释异常
