Java 获取错误：平台数据库平台不支持NativeSequence

我正在尝试为JavaSpring批处理应用程序DAO层编写junit测试用例。当我使用自定义序列生成器配置数据层对象并运行测试用例时，我得到了以下异常

异常说明：SEQ_EMPLOYEE_ID:平台数据库平台不支持NativeSequence

对于数据持久性，我使用JPA+EclipseLink

下面提到了我用于Junit的配置文件

上课

JunitPersistence.xml

本机序列对象特定于所使用的数据库-您需要指定本机序列工作时应使用的正确数据库平台。如果数据库不是从Spring获取或由Spring设置的，则需要添加persistence属性来指定数据库。

添加到persistence XML中。它起作用了！！谢谢

@Entity
@Table(name = "EMPLOYEE")
@NamedQuery(name = "test.test",
        query = "SELECT d FROM EmployeeDO d where d.status = 'COMPLETED'")
public class EmployeeDO implements Serializable {
    private static final long serialVersionUID = 1L;

    @SequenceGenerator(name = "employeeIdSequence", allocationSize = 1,
            sequenceName = "SEQ_EMPLOYEE_ID")
    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "employeeIdSequence")
    @Column(name = "BATCH_ID")
    private long batchId;

}
