ValidationException异常描述：在关系属性中使用非实体作为目标实体

我收到以下异常并且之前完成了所有这1000次，但现在我收到了错误：

ValidationException异常描述：[class com.smartphonedev.rsvplaw.entities.Staff]使用非实体[class com.smartphonedev.rsvplaw.entities.Address]作为关系属性[field addresses]中的目标实体 .

这是有问题的实体 . 有人能帮我辨别我的人际关系有什么问题吗？

<code>
@Entity
@Table(name="address")
public class Address implements Serializable,
{
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;

@Column(name="addressType")
@Enumerated(EnumType.ORDINAL)
private AddressType addressType;

@Column(name="streetLineOne")
private String streetLineOne;

@Column(name="streetLineTwo")
private String streetLineTwo;

@Column(name="city")
private String city;

@Column(name="adState")
private String state;

@Column(name="postCode")
private String postCode;    

@OneToMany(fetch=FetchType.LAZY, targetEntity=PhoneNumber.class, cascade = {CascadeType.MERGE,   CascadeType.REFRESH, CascadeType.DETACH},orphanRemoval=true)
@JoinColumn(name="phoneNumbers")
private Collection<PhoneNumber> phoneNumbers;
…..
}

@Entity
@Table(name="staff")
public class Staff implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;

//private Profile profile;
@OneToOne(fetch=FetchType.LAZY,cascade = {CascadeType.MERGE, CascadeType.REFRESH, CascadeType.DETACH})
@JoinColumn(name="permission")
private Permission permission;

@OneToOne(fetch=FetchType.LAZY,cascade = {CascadeType.MERGE, CascadeType.REFRESH, CascadeType.DETACH})
@JoinColumn(name="login")    
private Login login;

@Column(name="firstName")
private String firstName;

@Column(name="surnameName")
private String surnameName;

@Column(name="emailAddress")
private String emailAddress;

@OneToMany(fetch=FetchType.LAZY, targetEntity=PhoneNumber.class, cascade = {CascadeType.MERGE, CascadeType.REFRESH, CascadeType.DETACH},orphanRemoval=true)
@JoinColumn(name="phoneNumbers")
private Collection<PhoneNumber> phoneNumbers;

@OneToMany(fetch=FetchType.LAZY, targetEntity=Address.class, cascade = {CascadeType.MERGE, CascadeType.REFRESH, CascadeType.DETACH},orphanRemoval=true)
@JoinColumn(name="addresses")
private Collection<Address> addresses;
}
</code

添加phoneNumber类 @Entity @Table(name="phone") public class PhoneNumber implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id;
`@Column(name="numberType")
@Enumerated(EnumType.ORDINAL)
private PhoneNumberType numberType;

@Column(name="phoneNumber")
private String phoneNumber;
}
