物理分页相关与加载到底部

Integer pageSize = json.get("pageSize")==null?0:Integer.valueOf(StringUtil.trim(json.get("pageSize")));//每页的个数
				Integer pageNum = json.get("pageNum")==null?0:Integer.valueOf(StringUtil.trim(json.get("pageNum")));//第几页

					JSONArray ja = JSONArray.fromObject(listData);
					List<Map<Object, Object>> csImages = new ArrayList<Map<Object, Object>>(ja.size());

	Integer totalCount = ja.size();//总条数
					Integer totalPage = 0;
	if(pageSize!=0&&pageNum!=0){
						totalPage = totalCount%pageSize==0?totalCount/pageSize:totalCount/pageSize+1;//总页数
						//做物理分页
						int start = (pageNum-1)*pageSize; 
						int end = pageSize*pageNum;
						for(int i=start;i<end;i++){
							if(i<totalCount){
								Map<Object, Object> maptemp = (Map<Object, Object>)ja.get(i);
								Map<Object, Object> tempt = new HashMap<Object, Object>();
								//Map<Object, Object> config1 = dataCoreManager.initSystemCofCache(CHANNEL_ID);
								//String domain = StringUtil.trim(config1.get(CmsContants.FAST_DFS_IMAGE_URL));
								//tempt.put("imgUrl", domain+maptemp.get("imgSrc"));
								tempt.put("imgUrl",maptemp.get("imgSrc"));
								tempt.put("skipUrl", maptemp.get("imgUrl"));
								tempt.put("name", maptemp.get("imgTitle"));
								csImages.add(tempt);
							}else{
								break;

					}
//csImages即为结果
