分页代码共享

1. 分页引用：
   

<jsp:include page="/jsp/common/resource_page.jsp"/>

2. resource_page.jsp代码：
   

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<c:set var="basePath" value="${pageContext.request.contextPath }" />
<ul class="pagination">
	<c:if test="${pages <=5}">
		<c:forEach items="${pagesList}" var="p" varStatus="status">
			<li <c:if test="${page eq status.index+1}">class="active"</c:if>><a
				href="javascript:void(0)"
				<c:if test="${page ne status.index+1}">onclick="searchList(${status.index+1})"</c:if>>${status.index+1}</a>
			</li>
		</c:forEach>
	</c:if>
	<c:if test="${pages >5}">
		<li <c:if test="${page eq 1}">class="disabled"</c:if>><a
			href="javascript:void(0)"
			<c:if test="${page ne 1}">onclick="searchList(${page-1})"</c:if>>&laquo;</a>
		</li>
		<c:forEach items="${pagesList}" var="p" varStatus="status" begin="${beginPage }" end="${endPage }">
			<li <c:if test="${page eq status.index+1}">class="active"</c:if>><a
				href="javascript:void(0)"
				<c:if test="${page ne status.index+1}">onclick="searchList(${status.index+1})"</c:if>>${status.index+1}</a>
			</li>
		</c:forEach>
		<li <c:if test="${page eq pages}">class="disabled"</c:if>><a
			href="javascript:void(0)"
			<c:if test="${page ne pages}">onclick="searchList(${page+1})"</c:if>>&raquo;</a>
		</li>
	</c:if>

</ul>
    

3. 根据页码请求数据：
   

function searchList(page){
    		var basePath = '${basePath}';
    		document.thisform.action = basePath+"/trade/queryOrder.htm?page="+page+"&rows=20";
    		$("#thisform").submit();   		
    	}

4. controller编码：
   

@RequestMapping(value = "/queryOrder.htm")
	public String queryOrderInfo(Model model, HttpServletRequest request, 
			HttpServletResponse response) throws ParseException {
		LOGGER.info(JSON.toJSONString(request.getParameterMap()));		
		// 分页数据
		String page = request.getParameter("page");
		String size = request.getParameter("rows");
		int offset = 0;
		if (null!=page&&!"".equals(page))
			offset = (Integer.parseInt(page) - 1) * Integer.parseInt(size);
		else
			page = "1";
		int limit = 20;
		if (null!=size&&!"".equals(size))
			limit = Integer.parseInt(size);
		//查询结果
		OrderDetailBo order = new OrderDetailBo();
		order = setOrderDetailBoValue(request, model, response, order);
		if (order == null) {
			return "forward:../index.htm";
		}
		List<OrderDetailBo> list = orderDetailService.queryPageList(order,offset,limit);
		int total = orderDetailService.queryCount(order);
		//返回页面model
		model.addAttribute("orderList", list);		
		pageBuildParameters(model,total,Integer.parseInt(page),limit);

		return "trade/orderQuery";

	}

5. pageBuildParameters方法的编码：
   

	private void pageBuildParameters(Model model,int total,int page,int limit) {
		model.addAttribute("total", total);
		model.addAttribute("page", page);
		model.addAttribute("size", limit);
		int pages = total%limit>0?(total/limit)+1:(total/limit);
//		pages = 5;测试
		model.addAttribute("pages", pages);
		List<Integer> pagesList = new ArrayList<Integer>();
		for (int i=0; i<pages; i++) {
			pagesList.add(i+1);
		}
		model.addAttribute("pagesList", pagesList);
		int beginPage = 0;
		int endPage = 4;
		if (pages>5) {
			int pageGroup = page%5>0?(page/5)+1:(page/5);
			if (pages-page>=5) {
				beginPage = (pageGroup-1)*5;
				endPage = pageGroup*5-1;
			} else {
				beginPage = pages-5;
				endPage = pages;
			}
		}
			
		model.addAttribute("beginPage", beginPage);
		model.addAttribute("endPage", endPage);
	}
