给你一个吧，我项目中用的java累

public class PaginationUtil {

	private int num; // 当前页号, 采用自然数计数 1,2,3,...

	private int size; // 页面大小:一个页面显示多少个数据

	private int rowCount;// 数据总数：一共有多少个数据

	private int pageCount; // 页面总数

	private int startRow;// 当前页面开始行, 第一行是0行

	private int first = 1;// 第一页 页号

	private int last;// 最后页 页号

	private int next;// 下一页 页号

	private int prev;// 前页 页号

	private int start;// 页号式导航, 起始页号

	private int end;// 页号式导航, 结束页号

	private int numCount = 10;// 页号式导航, 最多显示页号数量为numCount+1;这里显示11页。



	public PaginationUtil(int size, String str_num, int rowCount) {



		int num = 1;

		if (str_num != null) {

			num = Integer.parseInt(str_num);

		}

		this.num = num;

		this.size = size;

		this.rowCount = rowCount;

		this.pageCount = (int) Math.ceil((double) rowCount / size);



		this.num = Math.min(this.num, pageCount);

		this.num = Math.max(1, this.num);



		this.startRow = (this.num - 1) * size;

		this.last = this.pageCount;

		this.next = Math.min(this.pageCount, this.num + 1);

		this.prev = Math.max(1, this.num - 1);



		// 计算page 控制

		start = Math.max(this.num - numCount / 2, first);

		end = Math.min(start + numCount, last);

		if (end - start < numCount) {

			start = Math.max(end - numCount, 1);

		}

	}



	public int getNum() {

		return num;

	}



	public void setNum(int num) {

		this.num = num;

	}

	}



	public int getPageCount() {

		return pageCount;

	}



	public void setPageCount(int pageCount) {

		this.pageCount = pageCount;

	}



	public int getStartRow() {

		return startRow;

	}



	public void setStartRow(int startRow) {

		this.startRow = startRow;

	}



	public int getFirst() {

	}



	public int getLast() {

只要在你的分页页面中加入此页面传递url和参数就可以了，不清楚可以在联系我
