使用@OneToMany或@ManyToOne關係時，我的測試失敗。Hibernate，Spring數據：@OneToMany關係，反之亦然無效
實體：
@Entity
@Table(name = "CONTACTS")
public class Contact implements Serializable {
private static final long serialVersionUID = 8841543709585000683L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "CONTACT_ID")
private Long contactId;
@Column(name = "CONT_NAME", nullable = false)
private String name;
@Column(name = "LAST_NAME")
private String lastName;
@Column(name = "NICK_NAME")
private String nickName;
@OneToMany(targetEntity = TelephoneNumber.class, fetch = FetchType.EAGER, mappedBy = TelephoneNumber.CONTACT_FIELD_NAME, cascade = CascadeType.ALL)
private Set<TelephoneNumber> telephoneNumbers = new HashSet<TelephoneNumber>(0);
getters();
setters()
}
@Entity
@Table(name = "TELEPHONE_NUMBERS")
public class TelephoneNumber implements Serializable {
private static final long serialVersionUID = 4459049334214768290L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "NUMBER_ID")
private Long telephoneNumberId;
@Enumerated(EnumType.ORDINAL)
@Column(name = "TELEPHONE_TYPE", nullable = false)
private TelephoneType telephoneType;
@Column(name = "TELEPHONE_NUMBER")
private String telephoneNumber;
@JoinColumn(name = "CONTACT_ID", nullable = false)
@ManyToOne(targetEntity = Contact.class, fetch = FetchType.EAGER, cascade = CascadeType.ALL)
private Contact contact;
public final static String CONTACT_FIELD_NAME = "contact";
getters();
setters();
}
Spring上下文：

</persistence>
和（去年斷言原因failes 0電話，但其他領域存在）失敗的測試：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath*:spring/dbs-application-context.xml" })
@Transactional
public class ContactRepositoryTest {
@Autowired
private ContactRepository contactRepository;
@Autowired
private TelephoneNumberRepository telephoneNumberRepository;
@Test
public void testRepositorySaveMethod() {
Contact contact = new Contact();
contact.setLastName("Carter");
contact.setName("John");
contact.setNickName(null);
contact = this.contactRepository.save(contact);
Assert.assertNotNull(contact.getContactId());
TelephoneNumber telephoneNumber1 = new TelephoneNumber();
telephoneNumber1.setTelephoneNumber("093 7674441");
telephoneNumber1.setContact(contact);
telephoneNumber1.setTelephoneType(TelephoneType.HOME);
this.telephoneNumberRepository.save(telephoneNumber1);
TelephoneNumber telephoneNumber2 = new TelephoneNumber();
telephoneNumber2.setTelephoneNumber("093 7674441");
telephoneNumber2.setContact(contact);
telephoneNumber2.setTelephoneType(TelephoneType.MOBILE);
this.telephoneNumberRepository.save(telephoneNumber2);
contact = this.contactRepository.findOne(contact.getContactId());
Assert.assertEquals(2, contact.getTelephoneNumbers().size());
}
}
可能是什麼原因？我試着改變FetchType，但它不適合我。
