我常用的分页类
public class Pagination {/** * * @param pageNum * 当前页数 * @param pageCount * 总页数 * @param recordCount * 总记录数 * @param pageUrl * 页面 URL * @return */public static String getPagination(int pageNum, int pageCount,int recordCount, String pageUrl) {String url = pageUrl.contains("?") ? pageUrl : pageUrl + "?";if(!url.endsWith("?") && !url.endsWith("&")){url += "&";}StringBuffer buffer = new StringBuffer();buffer.append("第 " + pageNum + "/" + pageCount + " 页 共 " + recordCount+ " 记录 ");buffer.append(pageNum == 1 ? " 第一页 " : " <a href='" + url+ "pageNum=1'>第一页</a> ");buffer.append(pageNum == 1 ? " 上一页 " : " <a href='" + url + "pageNum="+ (pageNum - 1) + "'>上一页</a> ");buffer.append(pageNum == pageCount ? " 下一页 " : " <a href='" + url+ "pageNum=" + (pageNum + 1) + "'>下一页</a> ");buffer.append(pageNum == pageCount ?
