java+mongodb+分页

第一步 定义html

  <div class="cont" id="box">
									<div class="J_Message message J_ServerNotice service-notice" grid="root">
										<div class="main" grid="row-13" id="J_tbody" style="margin-top: 0px;">
									   </div>
									</div>
									<div id="paginationbar" class="paginationbar"></div>
									<!--分页导航-->
									<div id="displayNum" class="displayNum"></div>
									<!--每页显示数目导航-->
									<div class="clear"></div>
								</div>

第二部 写入js

  function searchHistory(page,disR){
		var fn = arguments.callee;
		var req = $('#f_1').serialize() + '&page='+(page||1)+'&displayRecord='+(disR=disR||10) +"&receiveId="+user_name + "&ran="+Math.random();//默认10
		$.post("/data/listChannelMessages.do", req, function(json) {
			if(json.success !== true){
				//提示报错
				alert(json.message);
			} else{
				var count 	= json.object.count,
				list 		= json.object.lists,
				p 			= json.object.page,
				pCount 		= json.object.pageCount;
				var $tbody = $('#J_tbody'), $box = $('#box');
				var html = '';
				$.each(list,function(i,n){
					var my_status = "未读";
					var status_class = '';
					var readyColor = 'color:#4F8EDC'; //蓝色

					for (var key in n.readFlag) {
						if(key == user_name && n.readFlag[key] == 1){
							status_class = "closed";
							readyColor = 'color:#595F69'; //黑色
							my_status = "已读";
						}
			        }

					var comeFrome = null;
					if(n.comeFrome == 'undefined' || n.comeFrome == null){
						comeFrome = "系统";
					}
					var sendDate;
					if(n.sendDate != null){
					var temp = new Date(n.sendDate);
					 	sendDate = temp.Format("yyyy-MM-dd hh:mm:ss");
					}

					var text =
				'<div class="J_List list">' +
				    '<div class="J_Item item clearfix">'+
						 	'<div class="div">'+
			                    '<a href="/message/viewChannelMessage.jspx?messageId='+n.messageId+'&receiveId='+user_name+
			                    '" style="'+readyColor+'"><span style="'+readyColor+';line-height:180%;">'+n.content+
			                '</span></a></div>'+
			                '<span class="time" style="float:right">'+sendDate+'</span>'+
					    
						'</div>'+
					'</div>';

					if(null != text && text != ""){
						html += text;
					}
				});
				$tbody.html(html);
				var sort = $('#tr_head').find('td');
				$('#count').html(" | 记录数("+count+")");

				//分页
				var $pag=$box.find('.paginationbar'),$dis=$box.find('.displayNum');
				$.sysop.pagination.init($pag,p,pCount,10,function(num){
					fn(num,disR);
				});
				//显示数目
				$.sysop.pagination.displayNum($dis,disR,function(){
					fn(1,this.innerHTML.slice(0,-1));
				});
			}
		});
	}
	$('#search').bind('click',function(){
		searchHistory(undefined,$.crm.getPageSize(), true);
	});
	$(function(){
		//backAutoFillForm.init('#search','#f_1');// 提交按钮 表单
		searchHistory(1,10,true);
	});

其中内置函数 可以在附件中找到

第三步  java

@MethodResourceDesc(name = "[data]获取站内信列表")
	@RequestMapping(value = "/data/listChannelMessages.do")
	@ResponseBody
	public Result listStationLetters(HttpServletRequest request,HttpServletResponse response){
		Result result = new Result();
		try{
			Query query = CRMQueryHelper.makeChannelMessageQuery(
					RequestHelper.getQueryFields(request, MessageChannel.RECEIVE_ID),
					MessageChannel.SEND_DATE, Order.DESCENDING);
			int allCount = (int)channelService.allCount(query);

			int pageSize = RequestHelper.getPageSize(request);
			if(0 == pageSize){
				pageSize = 20;
			}

			List<MessageChannel> list = channelService.list(
					query.skip(
							(RequestHelper.getPageIndex(request) - 1) * pageSize
							).limit(pageSize));

			PagingVO pagingObject = new PagingVO();
			pagingObject.setPageCount((allCount + pageSize) / pageSize);
			pagingObject.setPage(RequestHelper.getPageIndex(request));
			pagingObject.setCount(allCount);
			pagingObject.setLists(list);
			result.setCode(ResultCode.SUCCESS);
			result.setObject(pagingObject);

		}catch(Exception e){
			result.setMessage(e.getMessage());
			logger.error(e.getMessage());
		}
		return result;
	}
内置函数可在 CRMQueryHelper.zip PagingVO.zip  找到

第四部  直接实现即可

@Override
	public List<MessageChannel> list(Query query) {
		return mongoTemplate.find(query, MessageChannel.class, COLLECTIONS_NAME_STATUS);
	}
