我正在尝试使用JUnit测试Dao方法：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/applicationContext.xml" })
@TransactionConfiguration(transactionManager = "singletable", defaultRollback = false)
@Transactional
public class TestPersonneSingleTableDao {
@Autowired
private IHommeSingleTableDao iHommeDao;
@Autowired
private IFemmeSingleTableDao iFemmeDao;
/**
*
*/
@Test
public void testSavePersonne() {
// crée et enregistre un homme
HommeDo hommeDo = new HommeDo();
hommeDo.setNom("homme1");
hommeDo.setDatenaissance(new Date());
....
...
}
当我尝试运行它时它会输出我（6次，我有6种测试方法）：

它说我“引起：org.hibernate.DuplicateMappingException：复制表映射女性”，但我只有这3个数据对象：
@Pojo
@Entity(name = "PersonneSingleTableDo")
@Table(name = "personne")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "sexe", discriminatorType = DiscriminatorType.STRING)
public abstract class PersonneDo {
@Id
@GeneratedValue
@Column(name = "id")
private int id;
@Column(name = "nom")
private String nom;
@Column(name = "datenaissance")
private Date datenaissance;
@ManyToMany
@JoinTable(name = "amis", joinColumns = @JoinColumn(name = "idPersonne"), inverseJoinColumns = @JoinColumn(name = "idAmi"))
private List<PersonneDo> amis;
@ManyToMany
@JoinTable(name = "amis", joinColumns = @JoinColumn(name = "idAmi"), inverseJoinColumns = @JoinColumn(name = "idPersonne"))
private List<PersonneDo> amiDe;
...
getters/setters
...
@Pojo
@Entity(name = "HommeSingleTableDo")
//@Table(name = "personne")
@DiscriminatorValue(value = "homme")
public class HommeDo extends PersonneDo {
}
@Pojo
@Entity(name = "FemmeSingleTableDo")
//@Table(name = "personne")
@DiscriminatorValue(value = "femme")
public class FemmeDo extends PersonneDo {
}
我做了什么错了？
PS：@Pojo注释只是一个关心人的自定义验证器。
答案 0 :(得分：1)
您正在使用已经具有映射到表'@Table（name =“personne”）'的Abstract类。
由于你继承了子类FemmeDo，它仍然有表映射到那个。
这就是你得到'重复映射'例外的原因。
