HibernateTemplate.save() method is not inserting in DB - spring

Question

I am new to Spring and Hibernate. I am just trying to insert a new record in my table using Hibernate Spring Integration. Please see below code
My beans.xml file :

My hibernate.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

<property name="mobileNumber" column="MobileNumber" type="string"></property>
<property name="emailId" column="EmailId" type="string"></property>
</class>
</hibernate-mapping>
My DAO class :
package DAO;
import java.util.List;
import org.hibernate.Session;
import org.springframework.orm.hibernate4.HibernateTemplate;
import org.springframework.orm.hibernate4.support.HibernateDaoSupport;
import ContactDetailsDTO.ContactDetailsDTO;
public class ContactDetailsDAO {
private HibernateTemplate hibernateTemplate;
public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
}
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
public void insertIntoContact(ContactDetailsDTO cd){
try{
hibernateTemplate.save(cd);
}catch(Exception e){
e.printStackTrace();
}
}
public List<ContactDetailsDTO> getAllAccounts(){
return (List<ContactDetailsDTO>) hibernateTemplate.find("from ContactDetailsDTO");
}
}
When I try to getAllAccounts I can see select query in console and records from table, but when I try to insert new record in table, insert query is not displayed on console and new record is not inserted in table.
save() method is not inserting new record. Please check where I am wrong and reply
Thanks
