我们处于将休眠模式从 3.6 升级到 4.1.9 的模式，我遇到了一个错误

当我尝试持久化具有以下定义的休眠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 的休眠源代码时，我看到在为 SequenceIdentityGenerator 创建准备好的语句时，休眠不检查“hibernate.jdbc.use_get_generated_keys”（AbstractBatcher - 506）和版本 4.1.9（StatementPreparerImpl - 112）。

因此，我们的应用程序升级失败。知道这种变化背后的原因是什么吗？

我陷入了同样的问题。终于找到了出路。将此行放在您的 hibernate.cfg.xml 文件中。

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

并且可以在以下位置找到参考和解释：
