其实我需要在亚马逊s3服务器上同时上传多张图片.这是我的单文件上传代码::

TransferObserver transferObserver = transferUtility.upload(
                "selfiesharedev",     /* The bucket to upload to */
                mini_image_path,    /* The key for the uploaded object */
                file,        /* The file where the data to upload exists */
                CannedAccessControlList.PublicRead
        );

最佳答案 请检查一下！

  TransferManager tm = new TransferManager(myCredentials);

    ObjectMetadataProvider metadataProvider = new ObjectMetadataProvider() {
        void provideObjectMetadata(File file, ObjectMetadata metadata) {
            // If this file is a JPEG, then parse some additional info
            // from the EXIF metadata to store in the object metadata
            if (isJPEG(file)) {
                metadata.addUserMetadata("original-image-date", 
                                         parseExifImageDate(file));
            }
        }
    }

    MultipleFileUpload upload = tm.uploadFileList(
            myBucket, myKeyPrefix, rootDirectory, fileList, metadataProvider);
