windows 导出excel不会报错 ,部署到Liunx 导出excel报错

 

 

     

       // 读取文件路径要写成这个样子在liunx才不会报错
ClassPathResource classPathResource = new ClassPathResource("static/sexcelTelemp.xls");

String fileName = "aa.xls";

//文件名称统一编码格式
fileName = URLEncoder.encode(fileName, "utf-8");
//生成的导出文件
File destFile = File.createTempFile(fileName, ".xls");

//transformer转到Excel
XLSTransformer transformer = new XLSTransformer();
BufferedInputStream bis = null;

// 传入流文件和数据
Workbook workbook = transformer.transformXLS(inputStream1, beans);

os.flush();
os.close();
//将文件输入
InputStream inputStream = new FileInputStream(destFile);
// 设置response参数,可以打开下载页面
response.reset();
//设置响应文本格式
response.setContentType("application/vnd.ms-excel;charset=utf-8");
response.setHeader("Content-Disposition",

//将文件输出到页面
