AWS Java S3 上传错误：“配置文件不能为空”
尝试从我的 Java Spring 应用程序将文件上传到 Amazon S3 时遇到异常。方法非常简单：
private void productionFileSaver(String keyName, File f) throws InterruptedException {
String bucketName = "{my-bucket-name}";
TransferManager tm = new TransferManager(new ProfileCredentialsProvider());
// TransferManager processes all transfers asynchronously,
// so this call will return immediately.
Upload upload = tm.upload(
bucketName, keyName, new File("/mypath/myfile.png"));
try {
// Or you can block and wait for the upload to finish
upload.waitForCompletion();
System.out.println("Upload complete.");
} catch (AmazonClientException amazonClientException) {
System.out.println("Unable to upload file, upload was aborted.");
amazonClientException.printStackTrace();
}
}
它与亚马逊在这里提供的内容基本相同，并且在尝试此其他版本时会出现完全相同的消息（“配置文件不能为空”）的相同异常。问题与文件不存在或为空无关（我已经以一千种方式检查了通过方法接收的File参数在调用它之前是否存在）。TransferManager.upload
我找不到有关我的异常消息“配置文件不能为 null”的任何信息。错误日志的第一行如下：

我的 S3 策略允许为所有类型的用户获取和放置对象。
对正在发生的事情有任何想法吗？
