SSH框架HibernateDaoSupport中没有update方法

[jmonian]

HibernateDaoSupport 哪个是修改方法
为什么我找不到 update 方法呢 saveOrUpdate 方法 也没有

[BUG弄潮儿]

package cn.com.hibernate.dao.impl;

import org.springframework.dao.DataAccessException;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import cn.com.hibernate.dao.DeptDao;
import cn.com.hibernate.vo.Dept;

public class DeptDaoImpl extends HibernateDaoSupport implements DeptDao {

	// private static SessionFactory factory = null;
	//
	// static {
	// Configuration cfg = new Configuration();
	// cfg.configure();
	// factory = cfg.buildSessionFactory();
	// }

	public void addDept(Dept dept) {
		// Transaction tx = null;
		// Session session = null;
		// try {
		// session = factory.openSession();
		// tx = session.beginTransaction();
		// session.save(dept);
		// tx.commit();
		// session.close();
		// } catch (HibernateException e) {
		// tx.rollback();
		// throw new RuntimeException(e);
		// }
		try {
			this.getHibernateTemplate().save(dept);
		} catch (DataAccessException e) {
			throw new RuntimeException(e);
		}
	}

	public void deleteDept(Integer id) {
		try {
			this.getHibernateTemplate().delete(find(id));
		} catch (DataAccessException e) {
			throw new RuntimeException(e);
		}
	}

	public Dept find(Integer id) {
		try {
			return (Dept) this.getHibernateTemplate().load(Dept.class, id);
		} catch (DataAccessException e) {
			throw new RuntimeException(e);
		}
	}

	public void updateDept(Dept dept) {
		try {
			this.getHibernateTemplate().update(dept);
		} catch (DataAccessException e) {
			throw new RuntimeException(e);
		}
	}

}
