休眠功能不支持

Question

我使用spring來測試我的DAO。我正在使用JPA + Hibernate。

對於我的測試中我使用下面的HSQLDB版本：

<dependency> 
    <groupId>hsqldb</groupId> 
    <artifactId>hsqldb</artifactId> 
    <version>1.8.0.10</version> 
    <scope>test</scope> 
</dependency> 

下面是我對我的單元測試的persistence.xml：

<persistence-unit name="unit-test-pu" transaction-type="RESOURCE_LOCAL"> 
     <properties> 
     <property name="javax.persistence.jdbc.driver" value="org.hsqldb.jdbcDriver"/> 
     <property name="javax.persistence.jdbc.user" value="sa"/> 
     <property name="javax.persistence.jdbc.password" value=""/> 
     <property name="javax.persistence.jdbc.url" value="jdbc:hsqldb:mem:testdb"/> 
     <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/> 
     <property name="hibernate.archive.autodetection" value="class"/> 
     <property name="hibernate.show_sql" value="true"/> 
     <property name="hibernate.use_sql_comments" value="true"/> 
     <property name="hibernate.format_sql" value="true"/> 
     <property name="hibernate.hbm2ddl.auto" value="create"/> 
     </properties>  
    </persistence-unit> 

這是我的測試類：

@ContextConfiguration("/spring/test-context.xml") 
@TestExecutionListeners({TransactionalTestExecutionListener.class}) 
@Transactional 
public class BaseDaoTestCase extends AbstractJUnit4SpringContextTests { 

    @Autowired 
    private MockEntityDao dao; 

    @Test 
    public void testSave_success() { 
     MockEntity e = new MockEntity(); 
     dao.save(e); 
     assertNotNull(e.getId()); 
    } 
} 

注意：這個想法是針對內存HSQLDB實例測試我的DAO。每個測試方法都在由spring管理的事務中運行。

不幸的是，當我運行此我得到下面的異常從休眠狀態：

我的DAO的save（）方法的實現如下：

entityManager.persist(entity); 

我使用以下休眠版本：

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-entitymanager</artifactId> 
    <version>4.1.0.Final</version> 
    <scope>compile</scope> 
</dependency> 

有沒有人知道發生了什麼？

Answer 1

我有類似的問題。我更新我的依賴關係（特別是hsqldb）後：

<hibernate-core-version>4.1.5.Final</hibernate-core-version> 
    <spring.version>3.1.2.RELEASE</spring.version> 
    <hsqldb.version>2.2.8</hsqldb.version> 
    ... 
    <dependency> 
     <groupId>org.hsqldb</groupId> 
     <artifactId>hsqldb</artifactId> 
     <version>${hsqldb.version}</version> 
    </dependency> 

我的問題已解決。

Answer 2

你正在使用哪個模擬框架？我只是在學習與mock合作，所以這只是一個瘋狂的猜測，但確保你已經完成了初始化模擬所需的一切。也許這個問題與如何設置測試有關。

Answer 3

我遇到了JPA + Hibernate + HSQLDB的問題，但不是春天。 這裏是我的代碼：

EntityManagerFactory emf = Persistence.createEntityManagerFactory("persistenceUnit"); 
EntityManager em = emf.createEntityManager(); 
EntityTransaction tr = em.getTransaction(); 
tr.begin(); 
em.persist(new MyEntity()); 
tr.commit(); 
em.close(); 
emf.close(); 

拋出我一樣This function is not supported例外，但如果我這樣做沒有交易，沒有。就像這樣：

EntityManagerFactory emf = Persistence.createEntityManagerFactory("persistenceUnit"); 
EntityManager em = emf.createEntityManager(); 
em.persist(new MyEntity()); 
em.close(); 
emf.close(); 

現在的問題是，我沒有看到的變化反映在數據庫中。
