我有以下用户表和联系表。我想要做的是创建一个连接表，这将允许我加入3个联系人的单个用户 - 家庭住址，帐单地址和发货地址。如何用附加列创建连接表
目前我有一个用户和user_address之间的一对一映射，然后我有user_address和每个不同的地址类型之间的一对一映射。
我玩过多到多列多列，一对多但迄今没有成功。
有没有其他办法可以做到这一点？
一对一的映射：
User.java
/**
* Relationship to the User Address - extension of User
*/
@OneToOne(cascade = CascadeType.ALL, mappedBy = "user",fetch=FetchType.EAGER)
private UserAddress userAddress;
UserAddress.java
@Entity
@Table(name = "a_user_address")
@GenericGenerator(name = "user-primarykey", strategy = "foreign", parameters = @Parameter(name = "property", value = "user"))
@Audited
public class UserAddress extends Trackable implements Serializable
{
/**
* The unique identifier associated with the user. References user(id).
*/
@Id
@GeneratedValue(generator = "user-primarykey")
@Column(name = "user_id", unique = true, nullable = false)
private Long userId;
/**
*
*/
@OneToOne
@PrimaryKeyJoinColumn
private User user;
/**
* The unique identifier associated with the user's home/profile address
*/
@OneToOne(fetch=FetchType.LAZY, cascade=CascadeType.ALL)
@JoinColumn(name="home_addr_id", nullable=true, updatable=true)
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
private ContactInfo homeAddress;
/**
* The unique identifier associated with the user's billing address
*/
@OneToOne(fetch=FetchType.LAZY, cascade=CascadeType.ALL)
@JoinColumn(name="billing_addr_id", nullable=true, updatable=true)
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
private ContactInfo billingAddress;
/**
* The unique identifier associated with the user's shipping address
*/
@OneToOne(fetch=FetchType.LAZY, cascade=CascadeType.ALL)
@JoinColumn(name="shipping_addr_id", nullable=true, updatable=true)
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
private ContactInfo shippingAddress;
