pagers.java

用jsp做的一个小例子

package com.today.common;

import com.today.prodect.model.Logic;

public class Pagers {
	//当前页数
	private int cur_page;
	
	//总页数
	private int count_page;
	//每页显示的行熟
	private int per_page=3;
	//记录总条数
	private int count_rows;
	//总页数
	
	public int getCur_page() {
		return cur_page;
	}
	public void setCur_page(int cur_page) {
		this.cur_page = cur_page;
	}
	public int getCount_page(String table_name) {
		Logic logic=new Logic();
		this.setCount_rows(logic.getCountRows(table_name));
		if (count_rows % per_page == 0) {
			count_page = count_rows / per_page;
		    }
		    else {
		    	count_page = count_rows / per_page + 1;
		    }
		
		return count_page;
	}
	public void setCount_page(int count_page) {
		this.count_page = count_page;
	}
	public int getPer_page() {
		return per_page;
	}
	public void setPer_page(int per_page) {
		this.per_page = per_page;
	}
	public int getCount_rows() {
		
		return count_rows;
	}
	public void setCount_rows(int count_rows) {
		this.count_rows = count_rows;
	}
	

}
