Spring封裝Hibernate：
有兩種手段：1、使用HibernateTemplate；2、繼承HibernateDaoSupport（實際上，HibernateDaoSupport本身就是對HibernateTemplate的一個封裝）
一切盡在代碼中，查看API唉！
注意：hibernate 2.X和hibernate3.X的區別，我用的是2.X 。 
package com.company.example.dao;
import java.util.List;
import com.company.example.model.Student;
public interface StudentDao {
public abstract Student getStudent(final Integer id);
public abstract void updateStudent(Student student);
public abstract List findStudentsByLastName(String lastName);
}
==================
package com.company.example.dao.hibernateImpl;
import java.util.List;
import net.sf.hibernate.Hibernate;
import net.sf.hibernate.HibernateException;
import net.sf.hibernate.Session;
import org.springframework.orm.hibernate.HibernateCallback;
import org.springframework.orm.hibernate.HibernateTemplate;
import com.company.example.dao.StudentDao;
import com.company.example.model.Student;
public class StudentDaoHibernate implements StudentDao {
HibernateTemplate hibernateTemplate;
public static void main(String[] args) {
}
public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
}
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
public Student getStudent(final Integer id) {
return (Student) hibernateTemplate.execute(new HibernateCallback() {
public Object doInHibernate(Session session)
throws HibernateException {
return session.load(Student.class, id);
}
});
}
public Student getStudent2(Integer id) {
return (Student) hibernateTemplate.load(Student.class, id);
}
public void updateStudent(Student student) {
hibernateTemplate.update(student);
}
public List findStudentsByLastName(String lastName) {
return hibernateTemplate.find("from Student student "
+ "where student.lastName = ?", lastName, Hibernate.STRING);
}
public class StudentDaoHibernate extends HibernateDaoSupport
implements StudentDao {
