CreateQuery सक्रिय लेन-देन

Question

मैं वसंत @Transactional एनोटेशन उपयोग करने के लिए कोशिश कर रहा हूँ बिना वैध नहीं है, लेकिन मैं समस्या है जब विधि findAll कहा जाता है और मैं इस त्रुटि है:

org.hibernate.HibernateException: createQuery is not valid without active transaction

व्यक्ति डीएओ :

@Repository 
@Transactional 
public class PersonDataAccesObject implements IPersonDataAccesObject { 

    @Autowired 
    private SessionFactory session; 

    @Override 
    public List findAll() { 
     return session.getCurrentSession().createQuery("from persons").list(); 
    } 

और यह मेरी servlet-context.xml:

<!-- Enables the Spring MVC @Controller programming model --> 
<annotation-driven /> 

<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory --> 
<resources mapping="/resources/**" location="/resources/bootstrap/" /> 

<!-- Database Configuration --> 
<context:property-placeholder location="classpath:database.properties" /> 

<beans:bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
    <beans:property name="driverClassName" value="${jdbc.driverClassName}" /> 
    <beans:property name="url" value="${jdbc.databaseUrl}" /> 
    <beans:property name="username" value="${jdbc.username}" /> 
    <beans:property name="password" value="${jdbc.password}" /> 
</beans:bean> 

<!-- Hibernate session factory --> 
<beans:bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> 
    <beans:property name="dataSource" ref="dataSource"/> 

    <beans:property name="hibernateProperties"> 
     <beans:props> 
      <beans:prop key="hibernate.connection.pool_size">${hibernate.pool_size}</beans:prop> 
      <beans:prop key="hibernate.dialect">${hibernate.dialect}</beans:prop> 
      <beans:prop key="hibernate.current_session_context_class">${hibernate.current_session}</beans:prop> 
      <beans:prop key="hibernate.cache.provider_class">${hibernate.provider_class}</beans:prop> 
      <beans:prop key="hibernate.show_sql">${hibernate.show_sql}</beans:prop> 
      <beans:prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl}</beans:prop> 
     </beans:props> 
    </beans:property> 

    <beans:property name="mappingResources"> 
     <beans:list> 
      <beans:value>hibernate.cfg.xml</beans:value> 
     </beans:list> 
    </beans:property> 
</beans:bean> 

<!-- Hibernate TransactionManager --> 
<beans:bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> 
    <beans:property name="sessionFactory" ref="sessionFactory"/> 
</beans:bean> 

मैंने इस लाइन को <beans:prop key="hibernate.current_session_context_class">${hibernate.current_session}</beans:prop> हटाने की कोशिश की, लेकिन एक और त्रुटि आई है, यह क्यों काम नहीं कर रहा है?

Answer 1

आप स्पष्ट रूप से लेन-देन प्रबंधक टिप्पणी के लिए समर्थन

अपने config में जोड़े घोषित करने के लिए है: "tx = http://www.springframework.org/schema/tx:

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

tx xmlns है "नेमस्पेस।

और इस लाइन को हटाना:

<beans:prop key="hibernate.current_session_context_class">${hibernate.current_session}</beans:prop>
