I am working on Spring MVC project. I am using Hibernate directly. The error No Session found for current thread
has occurred in my project. I know that on stackoverflow and on other places on the web this error is very common. But I haven't found working solution to my issue.
I have had unresolved problem with proper configuration of Hibernate Session Factory. I have described it here: Can I use Hibernate Session Factory declared in DispatcherServlet Context instead of hibernate.cfg.xml? But finally I am using hibernate.cfg.xml
file and also Hibernate Session Factory defined in DispatcherServlet Context file. I have done some simple operations like persisting classes in database. And everything was OK.
At this moment my project has a lot of in common with Spring MVC Hibernate. I have added some annotations to my classes and I have created some new services classes.
My ServletDispatcher Context file contains this definitions:
<annotation-driven />
<context:annotation-config />
<context:component-scan base-package="finances.webapp" />
<!-- Data source -->
<beans:bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<beans:property name="driverClassName" value="com.mysql.jdbc.Driver" />
<beans:property name="url" value="jdbc:mysql://localhost/finances" />
<beans:property name="username" value="root" />
<beans:property name="password" value="root" />
</beans:bean>
<!-- Data source end -->
<!-- Hibernate session factory -->
<beans:bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<beans:property name="dataSource">
<beans:ref bean="dataSource" />
</beans:property>
<beans:property name="configLocation" value="classpath:hibernate.cfg.xml" />
</beans:bean>
<!-- Hibernate session factory end -->
<beans:bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<beans:property name="sessionFactory" ref="sessionFactory" />
</beans:bean>
<beans:bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
<beans:property name="transactionManager" ref="transactionManager" />
<beans:property name="transactionAttributes">
<beans:props>
<beans:prop key="save">PROPAGATION_REQUIRED</beans:prop>
</beans:props>
</beans:property>
</beans:bean>
In my pom.xml file I have only these two dependencies according to ORM:
<!-- Hibernate -->
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.1.4.Final</version>
</dependency>
<!-- EJB -->
<dependency>
<groupId>javax.ejb</groupId>
<artifactId>ejb-api</artifactId>
<version>3.0</version>
<scope>provided</scope>
</dependency>
Maybe problem is here? But I haven't any problem with missing packages earlier.
This is code from my controller:
UsersEntity user2 = new UsersEntity("qwerty", "qwerty", true);
usersService.addUser(user2);
The problem No Session found for current thread
has occured during invoking addUser()
method.
My DAO class:
@Repository
public class UsersHome {
@Autowired
private SessionFactory sessionFactory;
public void persist(UsersEntity transientInstance) {
sessionFactory.getCurrentSession().persist(transientInstance);
}
}
My service:
@Service
public class UsersService {
@Autowired
private UsersHome usersHome;
@Transactional(propagation = Propagation.REQUIRED)
public void addUser(UsersEntity user) {
usersHome.persist(user);
}
}
This code has stopped working when I have change method body in UsersHome
class. Previously I have been starting session before my action and ending session after my action. But using annotations and transactions it should work? Please give me some suggestions.
