java后台与 jsp页面的分页案例
java后台的方法public int page; /** 页数索引* */ public int pageIndex; /** 首页索引* */ public int index; /** 末页* */ public int max;/*** @see 获取新闻列表并分页* @return*/ public String getNewsList() {if(this.checkLogin()){pageSize = 5;if (page < 1) { page = 1;}int startIndex = (page - 1) * 5;newslist = newsService.getPage(startIndex, pageSize);intRowCount = newsService.getTotalCount();k = (intRowCount + pageSize - 1) / pageSize;intPageCount = (intRowCount + pageSize - 1) / pageSize;// 计算出总页数if (page > intPageCount) { page = intPageCount;}// f = (page -1)*pageSize;pageIndex = page;if (intPageCount <= 5) { index = 1; max = intPageCount;} else if (page < 5) { index = 1; max = 5;} else if (page / 5 != intPageCount / 5) { index = page - 2; if (intPageCount >= page + 2) { max = page + 2; } else { max = intPageCount; }} else { index = intPageCount - 4; max = intPageCount;}return SUCCESS;}else{return LOGIN;} }
