亚马逊S3 putObject Excel通过stream不工作（爪哇）
您好我使用的是亚马逊S3 sdk的Java和我想上传的dynamic创build的Excel。发生了什么，我可以保存在本地计算机上的文件使用：
//creating local file try { FileOutputStream fileOut = new FileOutputStream(new File("C:\\test.xls")); excelWorkBook.write(fileOut); fileOut.flush(); fileOut.close(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } 但是当我尝试通过stream在amazon s3上传没有任何事情发生，我得到的错误string

我被困在最后2天，我试图寻找解决scheme，但我还没有find一个。
码：
public void uploadToCloud() { AWSCredentials credentials = new BasicAWSCredentials( accessKey, secretKey); AmazonS3 s3client = new AmazonS3Client(credentials); HSSFWorkbook excelWorkBook=new HSSFWorkbook(); missingAbbreviationReport.createMissingChargeAbbreviationSheet(excelWorkBook); missingAbbreviationReport.createMissingDispositionAbbreviationSheet(excelWorkBook); //creating local file try { FileOutputStream fileOut = new FileOutputStream(new File("C:\\test.xls")); excelWorkBook.write(fileOut); fileOut.flush(); fileOut.close(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } //upload to amazon s3 ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(); try { excelWorkBook.write(byteArrayOutputStream); byteArrayOutputStream.close(); } catch (IOException e) { LOGGER.error(e.getMessage()); } byte[] bf=new byte[byteArrayOutputStream.toByteArray().length]; ByteArrayInputStream bi=new ByteArrayInputStream(bf); try { bi.read(byteArrayOutputStream.toByteArray()); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } ObjectMetadata objectMetaData =new ObjectMetadata(); objectMetaData.setContentType("application/vnd.ms-excel"); objectMetaData.setContentLength(byteArrayOutputStream.toByteArray().length); s3client.putObject(new PutObjectRequest("smartdata-missingslg-reports", "test.xls",bi,objectMetaData) ); }
更改以下两行： –
byte[] bf=new byte[byteArrayOutputStream.toByteArray().length]; ByteArrayInputStream bi=new ByteArrayInputStream(bf);
至
ByteArrayInputStream bi= ByteArrayInputStream(byteArrayOutputStream.toByteArray());
