java 导出excel 文件名 中文乱码

使用POI导出Excel，文件名中文乱码：

String fileName  =  "_费率-" + DateUtil.DateToStr(new Date());
response.setCharacterEncoding("UTF-8");
response.setContentType("application/vnd.ms-excel");
response.setHeader("content-disposition",
          "attachment;filename=" + 
          new String(fileName.getBytes("utf-8"),"ISO-8859-1" )+ ".xls");

尝试解决方案：

fileName = URLEncoder.encode(fileName, "UTF-8");
fileName = new String(this.fileName.getBytes("utf-8"),"ISO-8859-1");
