春3休眠4 - 有没有会话单元测试故障发现当前线程

我已经使用Spring和Hibernate多年，但这是使用Spring 3和Hibernate我的第一个项目4.春3休眠4 - 有没有会话单元测试故障发现当前线程

我成立Model类如：

@Entity 
@Table(name = "DICTIONARY_ENTRY", uniqueConstraints = @UniqueConstraint(columnNames = { 
     "DICTIONARY_UUID", "ANAGRAM", "WORD" })) 
public class DictionaryEntry extends Pojo implements 
     Comparable<DictionaryEntry> { 
    @Column(name = "ANAGRAM", nullable = false) 
    private String anagram; 

    @Column(name = "WORD", nullable = false, unique = true) 
    private String word; 

    @Column(name = "DEFINITION", nullable = false) 
    private String definition; 

    @ManyToOne(fetch = FetchType.EAGER) 
    @JoinColumn(name = "DICTIONARY_UUID", referencedColumnName = "UUID", nullable=false) 
    private Dictionary dictionary; 

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "fromEntry") 
    /*package*/ Set<CrossReference> fromReferences; 

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "toEntry") 
    /*package*/ Set<CrossReference> toReferences;

每在春节手册中的，然后我建立了我的DAO和org.springframework.orm.hibernate4.LocalSessionFactoryBean的一个实例注入。然后我打电话的getSession（），它是：

/** 
    * Get the current session for a hibernate query 
    * @return the current session 
    */ 
    protected Session getSession(){ 
    return sessionFactory.getCurrentSession(); 
    }

然后我跑我的单元测试，在我的会话工厂注入并运行此方法：

object = (T) getSession().save(object);

会抛出：

Spring配置？ – madth3 2013-03-18 23:29:24

我认为你的测试可能缺少TransactionConfiguration注释。请尝试以下 -

@TransactionConfiguration(transactionManager="txManager")

或者，你可以改变你的bean定义事务管理器如下 -

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 
<property name="dataSource" ref="testDatabase"/>

默认春天试图找到 'transactionManager的' 豆。

我将txManager重命名为transactionManager，但没有喜悦。还没有找到与@TransactionConfiguration的jar文件。 – Thom 2013-03-19 00:55:55

你可以发布你的测试课吗？ – Sashi 2013-03-19 01:05:38

有需要修改两件事情：

首先，你正在使用Hibernate作为持久化，所以你需要使用HibernateTransactionManager来代替DataSourceTransactionManager对象。

<!-- Transaction Configuration For All Services (including Hibernate and MyBatis)--> 
<bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> 
    <property name="sessionFactory" ref="sessionFactory" /> 
</bean> 

<!-- Transaction: enable annotation-driven transaction --> 
<!--Put @Transactional on service impl instead of service interface--> 
<tx:annotation-driven transaction-manager="txManager" proxy-target-class="true"/>

其次，你正在使用Hibernate的4.x的，所以你需要配置当前会话的上下文类这样的：

<property name="hibernateProperties"> 
     <props> 
      <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop> 
      <prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop>

有关信息，请参考http://blog.springsource.org/2012/04/06/migrating-to-spring-3-1-and-hibernate-4-1/

我希望你通过它

只是为了增加，如果你想使用spring事务，你将无法获得会话，请参阅此链接了解详情http://stackoverflow.com/questions/18832889/spring-transactions-and-hibernate-current -session上下文级 – 2014-02-12 13:25:52

我在我的同样的问题junit在Spring 3应用程序中使用hibernate 3.6进行测试。
当应用程序服务器上运行，该会话与会话过滤管理：

<filter> 
    <filter-name>hibernateFilter</filter-name> 
    <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class> 
</filter>

但运行JUnit没有加载它的时候，你要模仿它在您的测试。
建议的一个解决方案是使用@TransactionConfiguration或者扩展AbstractTransactionalJUnit4SpringContextTests，但如果您有一个服务层类用@Service @Transactional进行注释并且在测试中多次调用它，那么它不起作用。

我解决了如下，根据this后：

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = {"classpath:context.xml"}) 
public class JUnitTestBase extends AbstractJUnit4SpringContextTests { 
    @Autowired 
    protected Log logger; 

    @Autowired 
    protected SessionFactory sessionFactory; 

    protected FlushMode flushMode = FlushMode.MANUAL; 

    @Before 
    public void setUp() throws Exception { 
     Session session = getSession(this.sessionFactory); 
     TransactionSynchronizationManager.bindResource(sessionFactory,new SessionHolder(session)); 
     logger.debug("Hibernate session is bound"); 
    } 

    @After 
    public void tearDown() throws Exception { 
     SessionHolder sessionHolder = (SessionHolder) TransactionSynchronizationManager.unbindResource(sessionFactory); 
     closeSession(sessionHolder.getSession(), sessionFactory); 
     logger.debug("Hibernate session is closed"); 
    } 

    protected void closeSession(Session session, SessionFactory sessionFactory) { 
     SessionFactoryUtils.closeSession(session); 
    } 

    protected Session getSession(SessionFactory sessionFactory) throws DataAccessResourceFailureException { 
     Session session = SessionFactoryUtils.getSession(sessionFactory, true); 
     FlushMode flushMode = this.flushMode; 
     if (flushMode != null) { 
      session.setFlushMode(flushMode); 
     } 
     return session; 
    } 
}
