Dao:

package com.test.dao;

import com.test.model.Customer;

public interface UserDao {

public void Add(Customer c);
}

DaoImpl:

package com.test.daoImpl;

             import org.hibernate.HibernateException;
            import org.hibernate.classic.Session;
            import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
            import com.test.dao.UserDao;
            import com.test.model.Customer;

            public class UserDaoImpl extends HibernateDaoSupport implements UserDao    {

                     public void Add(Customer c){
                                   Session session = null;
                                   try {
                                        getHibernateTemplate().save(c);
                                  } catch (HibernateException e) {
                                       // TODO Auto-generated catch block
                                     e.printStackTrace();
                       }
             }
        }

Service:

package com.test.service;

import com.test.dao.UserDao;

public class AddService {
private UserDao userDao;

                         public UserDao getUserDao() {
                                  return userDao;
                        }

                         public void setUserDao(UserDao userDao) {
                                this.userDao = userDao;
                          }
                  }

Test:

package com.test.service;

import org.springframework.context.support.ClassPathXmlApplicationContext;

                  import com.test.dao.UserDao;
                  import com.test.daoImpl.UserDaoImpl;
                 import com.test.model.Customer;

                 public class AddServiceTest {
                            public static void main(String args[]){
                                              ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");

                                                UserDao impl = (UserDaoImpl)ctx.getBean("addservice");

                                                 Customer c = new Customer();
                                                c.setName("注释换");
                                                 c.setPassword("zhushihuan");
                                                 impl.Add(c);

}
}
