userbo.java

仿google 分页的非常好的方法啊

package com.bo;

import java.util.ArrayList;
import java.util.List;

import com.dao.UserDAO;

public class UserBO {
public List list(){
	UserDAO dao=new UserDAO();
	List al=null;
	al=dao.list();
	return al;
}
public int count(){
	UserDAO dao=new UserDAO();
	return dao.count();
}
public List page(int num){ 
	UserDAO dao=new UserDAO();
	return dao.page(num);
}
/**
 * @param page
 * @param now_page
 * @return
 */
public String page_cut(int page,int now_page){
	UserDAO dao=new UserDAO();
	if(page==0){
		return "";
	}else{
	return dao.page_cut(page, now_page);
	}
}
}
