SSH2空指针异常 java.lang.NullPointerException

这个是我异常异常信息
EmployeeImpl----ID----------------->2Exception in thread "main" java.lang.NullPointerException
at com.softeem.employee.dao.EmployeeImpl.findById(EmployeeImpl.java:36)
at com.softeem.employee.dao.EmployeeImpl.main(EmployeeImpl.java:46)
下面是我的代码
package com.softeem.employee.dao;

import java.util.List;

import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.softeem.employee.pojo.Employee;

public class EmployeeImpl extends HibernateDaoSupport implements IEmployeeDAO {
public Employee findById(int id) {
System.out.print("EmployeeImpl----ID----------------->"+id);
Employee e = (Employee) getHibernateTemplate().get(Employee.class, id);
return e;
}

    public static void main(String[] args) {
    EmployeeImpl ei = new EmployeeImpl();
    ei.findById(2);

}

}
我传个值进去就报了空指针不知道怎么回事希望有人帮我下！

发下你的EmployeeImpl配置文件
