	调用:
		List resultList=new ArrayList();			
			for (int i = 0; i < list.size(); i++) {
				。。。。。。
				InspectionStisfaction vo=new InspectionStisfaction();
				vo.setXjrq(SystemUtil.getTimeStr2Str(String.valueOf(map.get("apply_date"))));
				vo.setXjsl(lxjsl);
				vo.setFcmy(lfcmy);
				vo.setMy(lmy);
				vo.setYb(lyb);
				vo.setBmy(lbmy);
				vo.setFcbmy(lfcbmy);
				resultList.add(vo);
			}
			
			//生成EXcel
			Map beans = new HashMap();
			beans.put("resultList",resultList);
			String path=SystemUtil.doExcel("巡检商户满意度报表模板.xls" , beans, "巡检商户满意度报表.xls");
			SystemUtil.doDownLoad(path, "巡检商户满意度报表.xls",this.response);
			return null;

   
   模板样式:	
			巡检数量(个)	  总体满意度	非常满意	满意	   一般	      不满意	 非常不满意  合计
			<jx:forEach items="${resultList}" var="l">							
			${l.xjrq}	      ${l.xjsl}		${l.fcmy}	${l.my}	   ${l.yb}	  ${l.bmy}	 ${l.fcbmy}   $[B#+C#+D#]
			</jx:forEach>							
			当月数量总计(个)  $[SUM(B4)]	$[SUM(D4)]	$[SUM(E4)] $[SUM(F4)] $[SUM(G4)] $[SUM(H4)]   $[SUM(I4)]
