Question

我正在尝试使用elasticbean将文件上传到s3。它在本地工作，但在生产中得到下一个错误：

上传代码是下一个：

public String store(MultipartFile file, String folder, String id) {
    try {
        if (file.isEmpty()) {
            throw new StorageException("Failed to store empty file " + file.getOriginalFilename());
        }

        String extension = FilenameUtils.getExtension(file.getOriginalFilename());
        String newName = id+"."+extension;

        AmazonS3 s3client = new AmazonS3Client(new BasicAWSCredentials("KEY1", "KEY2"));
        System.out.println("Uploading a new object to S3 from a file\n");
        String fileDestiny = "uploads/"+folder+"/"+newName;

        File convFile = new File(file.getOriginalFilename());
        FileOutputStream fos = new FileOutputStream(convFile); 
        fos.write(file.getBytes());
        fos.close(); 

        s3client.putObject(new PutObjectRequest(s3Bucket, fileDestiny, convFile));

        return newName;
    } catch (Exception e) {
        throw new StorageException("Failed to store file " + file.getOriginalFilename(), e);
    }
}

不确定是什么问题，用户也可以完全访问s3和ec2。我不知道该函数是否试图在de elasticbean机器内创建一个临时文件，也许它没有访问权限。

最后我做到了，问题是你无法在ElasticBean中的文件系统中写入，所以我替换了这一行：

File convFile = new File(file.getOriginalFilename());
FileOutputStream fos = new FileOutputStream(convFile); 
fos.write(file.getBytes());
fos.close(); 

s3client.putObject(new PutObjectRequest(s3Bucket, fileDestiny, convFile));

有了这个：

ObjectMetadata metadata = new ObjectMetadata();
metadata.setContentLength(file.getSize());                

s3client.putObject(new PutObjectRequest(s3Bucket, fileDestiny, file.getInputStream(), metadata));

最后工作！

无法使用Elasticbean中的Jhipster将生产中的文件上传到s3，但在本地工作
