hibernamte中基础持久化类BaseDao及实现BaseDaoImpl

package com.ssh.neb.dao;


import java.io.Serializable;
import java.util.Collection;
import java.util.List;



public interface BaseDao {
    
	public Object find(String queryString,Object[] values);
	
	public List findList(String queryString, Object[] values);
	
    public List getAllObject(Class clazz);
    
    public Object getObject(Class clazz, Serializable id);
    
    public void saveObject(Object o);
    
    public void removeObject(Class clazz, Serializable id);
    
    public void removeObject(Object o);
    
    public void removeAllObject(Collection collection);
    
    public Object findBy(Class clazz , String name, Object value);
    
    
    public List findLike(Class clazz, String name, String value);
    
    public List findAllBy(Class clazz , String name, Object value);
    
    public void flush();
    
}

 以下是实现类，我感觉还行基本的增删改查都有，拿出来分享下：

package com.ssh.neb.daoImpl;

import java.io.Serializable;
import java.util.Collection;
import java.util.List;


import org.hibernate.Criteria;

import org.hibernate.criterion.Restrictions;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.ssh.neb.dao.BaseDao;


public class BaseDaoImpl extends HibernateDaoSupport implements BaseDao {

	public List findAllBy(Class clazz, String name, Object value) {
		Criteria cr = getSession().createCriteria(clazz);
		cr.add(Restrictions.in(name, new Object[]{value}));
		List list = cr.list(); 
		return list;
	}

	public Object findBy(Class clazz, String name, Object value) {
		Criteria cr = getSession().createCriteria(clazz);
		cr.add(Restrictions.in(name, new Object[]{value}));
		return cr.list().get(0);
	}

	public List findLike(Class clazz, String name, String value) {
		Criteria cr = getSession().createCriteria(clazz);
		cr.add(Restrictions.like(name, "%"+value+"%"));
		return cr.list();
	}

	public void flush() {
		getHibernateTemplate().flush();
	}

	public List getAllObject(Class clazz) {

		return this.getHibernateTemplate().loadAll(clazz);

		//return getHibernateTemplate().loadAll(clazz);

	}

	public Object getObject(Class clazz, Serializable id) {
		return getHibernateTemplate().load(clazz, id);
	}
	public void removeAllObject(Collection collection) {
		getHibernateTemplate().deleteAll(collection);
	}

	public void removeObject(Class clazz, Serializable id) {
		Object object = this.getHibernateTemplate().load(clazz, id);
		getHibernateTemplate().delete(object);
	}

	public void removeObject(Object o) {
		getHibernateTemplate().delete(o);
	}

	public void saveObject(Object o) {
		getHibernateTemplate().saveOrUpdate(o);
	}

	public Object find(String queryString, Object[] values) {
		Object object = null;
		List list = getHibernateTemplate().find(queryString, values);
		if(list.size()>0)
			object = list.get(0);
			return object;
	}

	public List findList(String queryString, Object[] values) {
		return getHibernateTemplate().find(queryString, values);
	}

	

}
