AWS S3存储桶连接403错误

Question

AWSCredentials myCredentials = new BasicAWSCredentials(awsAccessKey, awsSecretKey);
AmazonS3 s3Client = new AmazonS3Client(myCredentials);

    S3Object object = new S3Object();
    object.setBucketName(existingBucketName);
    String keyName             = (storePath + "/" + file.getName()).replaceAll("//", "/");
    object.setKey(keyName);

    List<PartETag> partETags = new ArrayList<PartETag>();
    log.debug("Step 1 Start");
    // Step 1: Initialize.
    InitiateMultipartUploadRequest initRequest = new InitiateMultipartUploadRequest(existingBucketName, keyName);
    InitiateMultipartUploadResult initResponse =  s3Client.initiateMultipartUpload(initRequest);
    log.debug("Step 1 End");

最后3行抛出的错误如下： -
