Amazon s3对象Excel按流不工作（java）

您好，我正在使用amazon s3 sdk for java，我正在尝试上载动态创建的excel。如果我能够使用以下方法在本地计算机上保存文件，会发生什么情况：

//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();
    }

但是当我试图通过流在AmazonS3上上传时，什么也没有发生，我得到了如下错误字符串

com.amazonaws.services.s3.model.AmazonS3Exception: Status Code: 400, AWS Service: Amazon S3, AWS Request ID: BC86F8AED980C7A3, AWS Error Code: RequestTimeout, AWS Error Message: Your socket connection to the server was not read from or written to within the timeout period.

我被困在过去两天，我试图寻找解决方案，但我没有找到一个

代码：

---

更改以下两行：-

byte[] bf=new byte[byteArrayOutputStream.toByteArray().length];
ByteArrayInputStream bi=new ByteArrayInputStream(bf);

到

---

如何创建文件并不重要。我想说的是，只需剪切所有部分，将excel文件作为FileInputStream而不是

bi

读取，然后将其传递给

PutObjectRequest

。这是为了查找服务或防火墙的任何问题或其他问题。@bhantol我在PutObjectRequest中尝试了file object而不是stream。。它可以工作。。因此没有防火墙问题。请参阅。。我不想在上载前将文件存储在本地。这就是我使用ByteArrayInputStream（）的原因.检查防火墙..我猜您的

ByteArrayInputStream

是空的，没有写入任何内容。尝试用代码格式回答-您可以尝试post@Andremoniy当我尝试ro upload file对象而不是stream时，它会起作用。因此它不可能是防火墙问题。您确定已删除

尝试{bi.read（byteArrayOutputStream.toByteArray（））；}catch（IOE异常）{//TODO自动生成的捕获块e.printStackTrace（）；}

byte[] bf=new byte[byteArrayOutputStream.toByteArray().length];
ByteArrayInputStream bi=new ByteArrayInputStream(bf);

ByteArrayInputStream bi= ByteArrayInputStream(byteArrayOutputStream.toByteArray());
