一定要注意标红处，

ss:ExpandedRowCount="${rsvCountList?size + 2}

注：这里一定要改，因为这里设置的是excel的行数，要动态的加载数据，则行数也要跟着改变（设置的行数必须>=实际的行数，不然生成的excel会打不开），${RsvCountList?size + 6}是得到userList的大小加上原来标题格式所占的6行，${list？size}可以得到list的大小。

<#list rsvCountList as rsv>  
   			 
   			 <Row ss:Index="${rsv_index+2}">  

			    <Cell><Data ss:Type="String">${rsv.name!}</Data></Cell>
			    <#list rsv.countList as c> 
				    <Cell><Data ss:Type="String">${c.count!}</Data></Cell>  
			 	</#list>
			 	<Cell><Data ss:Type="String">${rsv.count!}</Data></Cell>
			 </Row>
			 </#list> 

循环遍历 RsvCountList的标签（内部又有list遍历）

解决模板读取和excel文件生成的路径问题

public void excelTest(HttpServletResponse response,HttpServletRequest request) throws IOException{
List<RsvCountList> rsvCountList = GetRsvCanton();
//测试Excel文件生成
Map<String,Object> data = new HashMap<String, Object>();
data.put("rsvCountList", rsvCountList);
Date now = new Date();
String filename = "/resources/TempFiles/excel"+now.getTime()+".xls";
String nodepath = this.getClass().getClassLoader().getResource("/").getPath(); 
String substring = nodepath+"../../";
String path2=substring+"/resources/template";

try {
TemplateParseUtil.parse(path2, "excel.ftl", substring+filename, data);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (TemplateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
response.sendRedirect("./"+filename);
   }
