HI,
Я пытаюсь добавить пользователя в базу данных из контроллера Spring MVC. и я получаю следующее исключение:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here
org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:656)
org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:560)
javax.servlet.http.HttpServlet.service(HttpServlet.java:637)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
Мой код следующий:
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="org.postgresql.Driver" />
<property name="url" value="jdbc:postgresql://127.0.0.1/doolloop2" />
<property name="username" value="doolloop2" />
<property name="password" value="doolloop" />
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="mappingLocations">
<list>
<value>WEB-INF/mapping/User.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
</bean>
<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<bean id="txService" class="com.doolloop.services.TxDataBaseServiceImpl">
<property name="sessionFactory">
<ref local="sessionFactory"/>
</property>
</bean>
Тогда мой сервис выглядит так:
public class TxDataBaseServiceImpl implements TxDataBaseService {
private SessionFactory sessionFactory;
public void setSessionFactory (SessionFactory sessionFactory)
{
this.sessionFactory = sessionFactory;
}
@Override
@Transactional
public void add(User user) {
Session session = this.sessionFactory.getCurrentSession();
Transaction tr = session.getTransaction();
tr.begin();
session.save(user);
tr.commit();
}
}
Теперь на моем сервлете я подключаю класс
@Autowired
private TxDataBaseServiceImpl service;
@RequestMapping(value="/signup.dlp",method = RequestMethod.POST)
public ModelAndView addUser(@Valid User user, BindingResult result){
logger.info("Return View");
registrationValidation.validate(user, result);
/// all required validations....
service.add(user);
ModelAndView mv = new ModelAndView("/Accounts/signupSuccess");
return mv;
}
Вопрос в том, что я делаю не так?
