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)]
