分页的一小段代码，比较健忘，存着自己用-优快云博客

本文介绍了一种分页逻辑的实现方法，并通过Java和JSP代码展示了如何根据当前页数动态调整显示的页码范围。该方法考虑了不同情况下的页面布局，如总页数较少或当前页接近总页数时的特殊处理。

				int total = Integer.parseInt(totalNum);
				int allPages = total % 10 == 0 ? total / 10 : total / 10 + 1;

				int pageLength = allPages > 9 ? 9 : allPages;

				int pagearr[] = new int[pageLength];

				if (page > 4) {
					if (allPages - page > 4) {
						for (int i = 0; i < 4; i++) {
							pagearr[i] = page + i - 4;
							pagearr[5 + i] = page + i + 1;
						}
						pagearr[4] = page;
					} else if (allPages > 9) {
						for (int i = 0; i < pageLength; i++) {
							pagearr[i] = allPages + i - 8;
						}
					} else {
						for (int i = 0; i < pageLength; i++) {
							pagearr[i] = i + 1;
						}
					}
				} else {
					for (int i = 0; i < pageLength; i++) {
						pagearr[i] = i + 1;
					}
				}
