Spring 4 + Hibernate 4: sessionFactory is null

Question

I use Spring 4.1.6.RELEASE + Hibernate 4.3.8.Final . After configuring and starting my web-app on Tomcat 7 I have sessionFactory == null .

Can you write what I did wrong? Here is my sources:

Here is my DAO-layer. I create base abstract class AbstractDao for CRUD operations and child classes with specific methods.

AbstractDao.java

package org.foxresult.dao.abstraction;

import org.foxresult.dao.interfaces.GenericDao;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.criterion.Order;
import org.springframework.beans.factory.annotation.Autowired;

import java.io.Serializable;
import java.util.List;


public abstract class AbstractDao<T, PK extends Serializable> implements GenericDao<T, PK> {

    @Autowired
    protected SessionFactory sessionFactory;

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

    public T getByPK(PK key) {
        T entry = null;
        Session session = null;
        if (key != null)
            try {
                session = sessionFactory.openSession();
                session.clear();
                entry = (T) session.get(getClassType(), key);
            } catch (Exception sql) {
                sql.printStackTrace();
            } finally {
                closeSession(session);
            }
        return entry;
    }

    public List<T> getAll() {
        List<T> result = null;
        Session session = null;
        try {
            session = sessionFactory.openSession();
            session.clear();
            result = session.createCriteria(getClassType()).
                        addOrder(Order.asc("id")).list();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            closeSession(session);
        }
        return result;
    }


    protected void closeSession(Session session) {
        if ((session != null) && (session.isOpen())) {
            session.close();
        }
    }
}

HibernateDepartmentDao.java

package org.foxresult.dao.implementations;

import org.foxresult.dao.abstraction.AbstractDao;
import org.foxresult.dao.interfaces.DepartmentDao;
import org.foxresult.entity.Department;

@Component
public class HibernateDepartmentDao extends AbstractDao<Department, Integer> implements DepartmentDao {

    public Class<Department> getClassType() {
        return Department.class;
    }

    public Integer getPK(Department object) {
        return object.getId();
    }
}

Hope you can help me. I'm beginner in Spring. Thanks!

Edited: added Tomcat log. When webapp are loaded I send GET-request to my service which call getAll method and I get NullPointerExeption for sessionFactory.

Edited (2) : added DepartmentResource.java. This is a Jersey REST-service.

package org.foxresult.resources;

import org.foxresult.dao.implementations.HibernateDaoFactory;
import org.foxresult.entity.Department;
import org.foxresult.entity.wrapper.DepartmentWrapper;

import javax.ws.rs.*;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import java.util.ArrayList;
import java.util.List;

@Path("/departments")
public class DepartmentResource {

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public List<DepartmentWrapper> getAll() {
        return wrap(HibernateDaoFactory.getDepartmentDao().getAll());
    }

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("/{id}")
    public DepartmentWrapper get(@PathParam("id") int id) {
        return wrap(HibernateDaoFactory.getDepartmentDao().getByPK(id));
    }
}

Answer 1

Updating my answer:

1. The web.xml should be using a Jersey Servlet that is "spring" capable.

In web.xml, change

 <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>

  To This:

 <servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>

2. For SpringServlet class to be available, make sure appropriate maven dependencies exist for jersey libaries.

So, in pom.xml add something like this:

<dependency>
            <groupId>com.sun.jersey.contribs</groupId>
            <artifactId>jersey-spring</artifactId>
            <version>1.8</version>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring-aop</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring-core</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring-web</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring-beans</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring-context</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

3. Make DepartmentResource have the @Component annotation.

4. This doesn't work for Spring: public static DepartmentDao getDepartmentDao() { return new HibernateDepartmentDao(); } public static DepartmentDao getDepartmentDao() { return new HibernateDepartmentDao(); }

You have to make Spring give you the Dao.

@Autowired
HibernateDepartmentDao hibernateDepartmentDao;

Answer 2

Your configuration seems correct. Can you try following steps

• Add ref to datasource in transaction manager as well.
  <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="dataSource" ref="dataSource"/> <property name="sessionFactory" ref="sessionFactory"/> </bean>

• Change the Annotation of HibernateDepartmentDao from @Component to @Repository
