Long contentLength = null;
System.out.println("Uploading a new object to S3 from a file
");
try {
    byte[] contentBytes = IOUtils.toByteArray(is);
    contentLength = Long.valueOf(contentBytes.length);
} catch (IOException e) {
    System.err.printf("Failed while reading bytes from %s", e.getMessage());

ObjectMetadata metadata = new ObjectMetadata();
metadata.setContentLength(contentLength);        
       
s3.putObject(new PutObjectRequest(bucketName, key, is, metadata));

推荐答案

是否有可能 IOUtils.toByteArray 正在耗尽您的输入流，以便在进行服务调用时没有更多数据可供读取?在这种情况下，stream.reset() 可以解决这个问题.

Is it possible that IOUtils.toByteArray is draining your input stream so that there is no more data to be read from it when the service call is made? In that case a stream.reset() would fix the issue.

但是如果你只是上传一个文件(而不是任意的 InputStream)，你可以使用更简单的 AmazonS3.putObject() 形式，它接受一个文件，然后你就不需要计算内容长度完全没有.

But if you're just uploading a file (as opposed to an arbitrary InputStream), you can use the simpler form of AmazonS3.putObject() that takes a File, and then you won't need to compute the content length at all.

这将多次自动重试任何此类网络错误.您可以通过使用 ClientConfiguration 对象实例化客户端来调整客户端使用的重试次数.

This will automatically retry any such network errors several times. You can tweak how many retries the client uses by instantiating it with a ClientConfiguration object.
