No Session found for current thread (HIBERNATE) - session

Question

OK JAVA guru ))
I really new to spring and I got into this trouble with "No session found the current thread" when I refer to the following page JSP security after login. Up to this point everything is working.
I need your help guys!!!!!
Here is my controller for that page:
package employee.controller;
import employee.service.AdminService;
import employee.service.UserService;
import org.apache.log4j.Logger;
import org.springframework.security.access.annotation.Secured;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import javax.annotation.Resource;
/**
* #author serge
*
* Handles and retrieves the common or admin page depending on the URI template.
* A user must be log-in first he can access these pages. Only the admin can see
* the adminpage, however.
*/
#Controller
#RequestMapping("/main")
public class MainController {
protected static Logger logger = Logger.getLogger("controller");
#Resource(name = "adminService")
private AdminService adminService;
#Resource(name = "userService")
private UserService userService;
/**
* Handles and retrieves a /WEB-INF/jsp/employee-page.jsp
*
* containing all employee
*
* #return the name of the JSP page
*/
#Secured("ROLE_USER")
#RequestMapping(value = "/employee-list",method = RequestMethod.GET)
public String getEmployeeListPage(Model model) {
logger.debug("Received request to show all employee page");
// Retrieve all employee and attach to model
model.addAttribute("all-employee", userService.findAllEmployee());
return "employee-page";
}
/**
* Handles and retrieves /WEB-INF/jsp/admin-page.jsp that only admins can see
*
* #return the name of the JSP page
*/
#Secured("ROLE_ADMIN")
#RequestMapping(value = "/admin", method = RequestMethod.GET)
public String getAdminPage() {
logger.debug("Received request to show admin page");
return "admin-page";
}
}
This is user service that had been called from controller:
package employee.service.impl;
import employee.DAO.EmployeeInfoDAO;
import employee.model.EmployeeInfo;
import employee.service.UserService;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.access.annotation.Secured;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
/**
* #author serge
*
* Reader level
*
* Service to Retrieve info about Employees
*/
#Service("userService")
#Transactional
public class UserServiceImpl implements UserService {
protected static Logger logger = Logger.getLogger("service");
private EmployeeInfoDAO emplInfoDAO;
#Autowired
public void setEmployeeDao(EmployeeInfoDAO emplInfoDAO) {
this.emplInfoDAO = emplInfoDAO;
}
/**
* Retrieving Employee Information by id
*
* #return EmployeeInfo object
*/
#Override
#Transactional
#Secured("ROLE_USER")
public EmployeeInfo findEmployeeByID(Integer id) {
logger.debug("Retrieving Employee with id= " + id);
EmployeeInfo employeeInfo = new EmployeeInfo();
employeeInfo.setId(id);
emplInfoDAO.find(employeeInfo);
return employeeInfo;
}
/**
* Retrieving all Employees
*
* #return List of EmployeeInfo object
*/
#Override
#Secured("ROLE_USER")
#Transactional(readOnly = true)
public List<EmployeeInfo> findAllEmployee() {
logger.debug("Retrieving all Employee");
return emplInfoDAO.findAll();
}
/**
* Retrieving Employees by last name
*
* #return List of EmployeeInfo object
*/
#Override
#Secured("ROLE_USER")
#Transactional(readOnly = true)
public List<EmployeeInfo> findAllByLastName(String lastName, Object paramValue) {
lastName = "lastName";
logger.debug("Retrieving Employee by last name: " + paramValue);
return emplInfoDAO.findAllByParam(lastName, paramValue);
}
/**
* Retrieving Employees by first name
*
* #return List of EmployeeInfo object
*/
#Override
#Secured("ROLE_USER")
#Transactional(readOnly = true)
public List<EmployeeInfo> findAllByFirstName(String firstName, Object paramValue) {
firstName = "firstName";
logger.debug("Retrieving Employee by first name: " + paramValue);
return emplInfoDAO.findAllByParam(firstName, paramValue);
}
}
And this is custom DAO support, not sure if this is right way to do that.... :
package employee.DAO.impl;
import employee.DAO.DAO;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.criterion.Restrictions;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.transaction.annotation.Transactional;
import javax.annotation.Resource;
import java.io.Serializable;
import java.util.List;
public class CustomHibernateDaoSupport<T> implements DAO<T> {
//was extending HibernateDaoSupport
private Class<T> clazz;
private SessionFactory sessionFactory;
public CustomHibernateDaoSupport(Class<T> clazz) {
this.clazz = clazz;
}
#Autowired
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
private Session getCurrentSession() {
return sessionFactory.getCurrentSession();
}
#Override
#Transactional
public void save(T entity) {
getCurrentSession().save(entity);
}
#Override
#Transactional
public void update(T entity) {
getCurrentSession().update(entity);
}
#Override
#Transactional
public void delete(Serializable key) {
Object entity = getCurrentSession().get(clazz, key);
if (entity != null) {
getCurrentSession().delete(entity);
}
}
#Override
#Transactional
public T find(Serializable key) {
return (T) getCurrentSession().get(clazz, key);
}
#Override
#Transactional
public List<T> findAll() {
return getCurrentSession().createCriteria(clazz).list();
}
#Override
#Transactional
public List<T> findAllByParam(final String paramName, final Object paramValue) {
return getCurrentSession().createCriteria(clazz)
.add(Restrictions.eq(paramName, paramValue))
.list();
}
}
And of course configuration:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</bean>
</beans>
after a successful login, I called /employee-list and got this instead of the page:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.hibernate.HibernateException: No Session found for current thread
org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:894)

employee.DAO.impl.CustomHibernateDaoSupport.getCurrentSession(CustomHibernateDaoSupport.java:31)
employee.DAO.impl.CustomHibernateDaoSupport.findAll(CustomHibernateDaoSupport.java:64)
...
Please help me understand where is my mistake, maybe I made a wrong configuration?

Answer 1

If you have dispatch-servlet.xml, add the
<tx:annotation-driven />
Or there is an alternative:
