departmentdao.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.Department;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

public class DepartmentDAO extends HibernateDaoSupport{

	public void insertDepartment(Department department) {
		getHibernateTemplate().saveOrUpdate(department);
	}

	public Department getDepartment(String departmentid) {
		return (Department) getHibernateTemplate().get(Department.class,
				new Integer(departmentid));
	}

	public List getDepartments() {
		return getHibernateTemplate().find("from Department");
	}

	public void deleteDepartment(String departmentid) {
		Object p = getHibernateTemplate().load(Department.class, new Integer(departmentid));
		getHibernateTemplate().delete(p);
	}
}
