在内存数据库休眠弹簧

Question

我一直在尝试在junit测试中将spring和memorydb集成，但我不断收到异常。

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

与定义其他豆类

我的服务类：

    @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类：

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

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

PS：我的Order类有其他属性引用其他类，但我没有映射它们，它们也不是实体。 任何建议

Answer 1

继this answer，知道你的XML映射，我建议以下标注更改订单ID：

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

这是假设@GeneratedValue相当于一个“原生”发生器，在你的XML。您可能需要有一个战略=原生反而更喜欢这个使用@GenericGenerator代替：

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