majordao.java

这是我自己做的一个选课系统

package org.hibernate.dao;

import java.util.List;

import org.hibernate.beans.Major;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

public class MajorDAO extends HibernateDaoSupport{

	public void insertMajor(Major major) {
		getHibernateTemplate().saveOrUpdate(major);
	}

	public Major getMajor(String majorid) {
		return (Major) getHibernateTemplate().get(Major.class,
				new Integer(majorid));
	}

	public List getMajors() {
		return getHibernateTemplate().find("from Major");
	}

	public void deleteMajor(String majorid) {
		Object p = getHibernateTemplate().load(Major.class, new Integer(majorid));
		getHibernateTemplate().delete(p);
	}
}
