Hibernate 4 - 未启用getGeneratedKeys()支持

Question

我们处于一种将hibernate从版本3.6升级到4.1.9的模式,我面临一个错误

当我尝试持久化具有以下定义的hibernate实体时,会出现此错误

@Entity
@Table(name = "ACCESS")
@GenericGenerator(name = "auth-generator",
    strategy = "sequence-identity",
    parameters = @org.hibernate.annotations.Parameter(name = "sequence", value = "ACCESS_SEQ"))
 public class Access implements Identifiable {
    private Long id;

   @Id
   @GeneratedValue(generator = "auth-generator")
   @Column(name = "ROW_IDENTIFIER", nullable = false)
    public Long getId() {
        return id;
    }
 }

在比较3.6的hibernate源代码时,我看到在为SequenceIdentityGenerator创建预准备语句时,hibernate不会检查"hibernate.jdbc.use_get_generated_keys"(AbstractBatcher - 506),而对于版本4.1.9,它会检查它(StatementPreparerImpl - 112).

因此,我们的应用程序升级失败.有什么想法这个变化背后的原因是什么？

我陷入了同样的问题.终于找到了出路.把这一行放在你的hibernate.cfg.xml文件中.

<property name="hibernate.jdbc.use_get_generated_keys">true</property>
