Java.lang.IllegalArgumentException: 'sessionFactory' or 'hibernateTemplate' required in spring + hibernate

I am doing spring + hibernate apllication. When I run the application on the tomcat server, I get some exception. Below is my code.

This is my bean configuration file.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

 <bean
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location">
        <value>WEB-INF/database/db.properties</value>
    </property>
</bean>
    <bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="${jdbc.driverClassName}" />
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
    </bean>

    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

        <property name="dataSource">
            <ref bean="dataSource" />
        </property> 
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>
        <property name="mappingResources">
            <list>
                <value>Employee.hbm.xml</value>
            </list>
        </property>
    </bean>
    <bean id="employeeBo" class="com.saggezza.employee.bo.impl.EmployeeBoImpl">
        <property name="employeeDao" ref="employeeDao" />
    </bean>

    <bean id="employeeDao" class="com.saggezza.employee.dao.impl.EmployeeDaoImpl">
        <constructor-arg ref="sessionFactory"></constructor-arg>
    </bean>

this is my dao class.

public class EmployeeDaoImpl extends HibernateDaoSupport implements EmployeeDao {

    private SessionFactory sessionFactory;
    public EmployeeDaoImpl(SessionFactory sessionfactory){
        this.sessionFactory=sessionfactory;
    }

    @Override
    public List<Employee> getEmployeeDetails() {
        return getHibernateTemplate().find("from Employee");

    }
}

Here another class employeeBo calls employeeDaoImpl. when I run this, I get the following exception.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'employeeBo' defined in ServletContext resource [/WEB-INF/spring/EmployeeBean.xml]: Cannot resolve reference to bean 'employeeDao' while setting bean property 'employeeDao'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'employeeDao' defined in ServletContext resource [/WEB-INF/spring/EmployeeBean.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: 'sessionFactory' or 'hibernateTemplate' is required

Can someone help solve this. I tried a lot and google too. But got a solution.

, sessionFactory. 'sessionFactory'. bean IllegalArgumentException.

: ,

public class EmployeeDaoImpl extends HibernateDaoSupport implements EmployeeDao {


public EmployeeDaoImpl(SessionFactory sessionfactory){
    setSessionFactory(sessionfactory);
}

@Override
public List<Employee> getEmployeeDetails() {
    return getHibernateTemplate().find("from Employee");

}
}

"sessionFactory" setter. . org.springframework.orm.hibernate3.support.HibernateDaoSupport.setSessionFactory(SessionFactory). .

, SessionFactory, EmployeeDaoImpl, SessionFactory, .

You can use Hibernate DAO Support by extending the HibernateDAOSupport class and overriding its afterPropertiesSet () method.

This method is called in support of HibernateDAO, and while sessionFactory is null, it causes this error. In your custom class, you can explicitly set this property and then call the same method of the parent class (i.e. the HibernateDAOSupport addProperties () method)

package com.techcielo.spring4.hibernate.template;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Component;

@Component("hibernateTemplate")
public class Hibernate4CustomTemplate extends HibernateTemplate{

    @Autowired(required=true)
    private SessionFactory sessionFactory;
    public void setSessionFactory(SessionFactory sessionFactory) {
        System.out.println("Setting SessionFactory");
        this.sessionFactory = sessionFactory;
        super.setSessionFactory(sessionFactory);
    }

    @Override
    public void afterPropertiesSet() {
    System.out.println("Checking if properties set..."+this.sessionFactory);
    setSessionFactory(sessionFactory);
    super.afterPropertiesSet();
    }
}

Below is an example sample !
