我有一個代碼,我使用envers和它的偉大工程。我在單獨的_AUD表上進行審計。但後來,我需要使用樂觀鎖定。但它不適用於@Audited
註釋。這裏是我的代碼休眠@審查衝突@版本
@MappedSuperclass
@Audited
public class BaseVO implements IXtrainVO
{
@Version
@Column(name = "Version")
private long version;
}
@Entity
@Table(name = "Person")
@Audited
public class PersonVO extends BaseVO
{
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "PersonId", unique = true, nullable = false)
private Long personId;
@Column(name = "Name", length = 80, nullable = false)
@NotBlank
@Size(max = 80)
private String name;
}
@Test
public void testLocking() throws Exception
{
PersonVO person = new PersonVO();
person.setName("John");
Long personId = personManager.savePerson(person);
PersonVO copy1 = personManager.findPerson(personId);
PersonVO copy2 = personManager.findPerson(personId);
copy1.setName("John1");
personManager.updatePerson(copy1);
copy2.setName("John2");
personManager.updatePerson(copy2);
}
代碼應該引發optimistict鎖定錯誤,但它沒有。相反,我得到
Caused by: java.sql.SQLException: Field 'Version' doesn't have a default value.
但是當我刪除@Audited
註釋,樂觀的作品,我也得到HibernateOptimisticLockingFailureException
這是我期待的。是否知道這兩個註釋不能很好地相互配合?我也試圖把@NotAudited
上的版本列,但仍然不工作
