在內存中db休眠狀態

Question

我一直在嘗試在junit測試中在spring和memorydb之間進行集成，但是我不斷收到異常。

org.hibernate.exception.SQLGrammarException: user lacks privilege or object not  found:    ORDERTABLE

與定義其他豆類

我的服務等級：

                 @RunWith(SpringJUnit4ClassRunner.class)
           @ContextConfiguration(locations = { "/testContext.xml" })
           @Transactional
           public class TestService {
        //ApplicationContext context = new ClassPathXmlApplicationContext(
                //"spring-config.xml");
        @Autowired
        PaypalPaymentsService PaypalService;

        @Autowired
        private OrderDAO orderDAO ;
        @Autowired
        private SessionFactory sessionFactory;
        private Session extSession;
        @Before
        @Transactional
        public void openSessionExternal() {
            extSession = sessionFactory.getCurrentSession();
        }
        @Test
        @Transactional
        public void shouldHaveASessionFactory() {
            assertNotNull(sessionFactory);
        }
        @Test
        @Transactional
        public void shouldHaveASession() {
            assertNotNull(extSession);
        }

        @Test
        public void saveOrder(){
            Order order = new Order();
            order.setOrderId("1");
            order.setRecieverEmail("enduser_biz@gmail.com");
            order.setAmount((double)2.00);
            extSession.save(order);
            Order testOrder = (Order) extSession.createQuery("from OrderTable where  orderId = ?").setParameter(0, "1").list().get(0);

            assertNotNull(testOrder);

        }

Order類：

    @Entity
    @Table(name="OrderTable")
    public class Order {

@Id
    @GeneratedValue
    @Column(name="orderId")
String orderId;

PS：我的Order類具有引用其他類的其他屬性，但我沒有映射它們，它們也不是實體。 有什么建議么

Answer 1

按照這個答案 ，並了解您的XML映射，我建議對orderId進行以下注釋更改：

@Id
@GeneratedValue
@Column(name="orderId", columnDefintion="BIGINT")
String orderId;

假定@GeneratedValue等同於XML中的“本機”生成器。 您可能需要使用@GenericGenerator代替，而將strategy = native改為這樣：

@Id
@GeneratedValue(generator="my-native-generator")
@GenericGenerator(name="my-native-generator", strategy = "native")
@Column(name="orderId", columnDefintion="BIGINT")
String orderId;
