没有Hibernate Session绑定到线程异常

Question

I have Hibernate 3.6.0.Final and Spring 3.0.0.RELEASE

I get "No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here"

If I add the thread specification back in, I get "saveOrUpdate is not valid without active transaction"

Any ideas?

The spring-config.xml:

<context:annotation-config />
<context:component-scan base-package="com.maxheapsize" />

<bean id="dataSource"
         class="org.apache.commons.dbcp.BasicDataSource"

        </bean>
    </property>

and the DAO:

public class NameDao {
    private SessionFactory sessionFactory;

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    @Transactional
    @SuppressWarnings("unchecked")
    public List<Name> getAll() {
        Session session = this.sessionFactory.getCurrentSession();
        List<Name> names = (List<Name>)session.createQuery("from Name").list();
        return names;
    }

    //@Transactional(propagation= Propagation.REQUIRED, readOnly=false)
    @Transactional
    public void save(Name name){
        Session session = this.sessionFactory.getCurrentSession();
        session.saveOrUpdate(name);
        session.flush();
    }
}

Answer 1

Spring version isn't your issue.

I'd also recommend not annotating your DAO with transactions. Those belong on a service tier that has the DAO injected in. That's where the session comes in as well: open the session for the use case, execute it, close the transaction, clean it up.

Answer 2

You forgot to enable annotation driven transaction management . In the link, search for tx:advice .

Answer 3

Add

<beans xmlns:tx="http://www.springframework.org/schema/tx

and

<tx:annotation-driven /> 

to your context file.

Answer 4

Comment the property in the hibernate.cfg.xml file

thread

Answer 5

add taransaction manager :

    <bean class="org.springframework.orm.hibernate3.HibernateTransactionManager"
    id="hibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"></property>
</bean>

<tx:annotation-driven transaction-manager="hibernateTransactionManager"/>

and annotate all ur DAO classes with @Transactional
