Question

I’m using Spring 3.1 and Hibernate 4.1, and I’m currently getting the following exception when I run a repository test:

Caused by: org.hibernate.HibernateException: No Session found for current thread
    at org.springframework.orm.hibernate4.SpringSessionContext.currentSession(SpringSessionContext.java:97)
    at org.hibernate.internal.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:1041)

Here’s what a DAO looks like. It uses the same generics dao pattern that basically everyone else is using:

@Repository
public class UserRepository extends RepositorySupport<User> {

    public UserRepository() {
        super(User.class);
    }

    public User findByUsername(final String username) {
        Query query = getCurrentSession().createQuery(
            "from User user " +
            "where user.username = :username"
        );

        return (User) query.setParameter("username", username)
            .uniqueResult();
    }

The only thing different here that I normally wouldn’t do is that I am not using getHibernateTemplate() anymore – and that’s why I suspect things aren’t working. I’d rather not use this method if I can avoid it, as the resultant code looks horrible.

My hibernate beans look like this:

<bean id="sessionFactory"
      class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="mappingResources">
        <list>
            <value>hibernate/tag.hbm.xml</value>
            <value>hibernate/address.hbm.xml</value>
            <value>hibernate/user.hbm.xml</value>
        </list>
    </property>
    <property name="namingStrategy">
        <bean class="org.hibernate.cfg.ImprovedNamingStrategy"/>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="javax.persistence.validation.mode">none</prop>

            <prop key="hibernate.dialect">${hibernate.dialect}</prop>
            <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}
            </prop>
            <prop key="hibernate.generate_statistics">false</prop>

            <prop key="hibernate.show_sql">false</prop>
            <prop key="hibernate.format_sql">true</prop>

            <prop key="hibernate.cache.use_second_level_cache">false</prop>
            <prop key="hibernate.cache.provider_class">

            </prop>
        </props>
    </property>
</bean>

<bean class="org.springframework.orm.hibernate4.HibernateExceptionTranslator"/>

<bean id="transactionManager"
      class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<!--
<bean id="hibernateInterceptor"
      class="org.springframework.orm.hibernate4.HibernateInterceptor">

<tx:advice id="transactionAdvice" transaction-manager="transactionManager">
    <tx:attributes>

        <tx:method name="get*" read-only="true" propagation="REQUIRED"/>
        <tx:method name="*" propagation="REQUIRED"/>
    </tx:attributes>
</tx:advice>

<aop:config>
    <aop:advisor advice-ref="transactionAdvice"
                 pointcut="execution(* *..service.*.*(..))" order="1"/>
    <!-- gets sub packages like service.user -->
    <aop:advisor advice-ref="transactionAdvice"
                 pointcut="execution(* *..service.*.*.*(..))" order="2"/>
</aop:config>

<bean id="validator"
      class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>

<context:annotation-config/>
<context:spring-configured/>
<context:component-scan base-package="com.realtywebsite.repositories,com.realtywebsite.service"/>

<task:annotation-driven />

My test code looks something like this (I have to flatten it because my tests extend from a common parent test class):

@ContextConfiguration(locations = {
    ObjectMother.APPLICATION_CONTEXT,
    ObjectMother.WEB_CONTEXT
})
public abstract class DatabaseTest extends AbstractTransactionalJUnit4SpringContextTests {


    @Test
    public void delete() {
        userRepository.delete(1);
        flush();

        assertFalse(userRepository.exists(1));
    }

    ...

Thanks for the help!

Answer 1

The class AbstractTransactionalJUnit4SpringContextTests is deprecated.

You have two choices:

• extend from AbstractTransactionalJUnit4SpringContextTests, or
• use SpringJUnit4ClassRunner (then you need to attach @Transactional)

I hope that would fix the problem.
