AWS S3 notificationConfiguration throws无法验证以下目标配置（服务：Amazon S3）

Question

我已通过java SDK创建了AWS S3和SNS。现在我正在尝试为创建的S3存储桶设置事件。以下是我的代码片段

private void createS3Event(String snsTopicARN) { 
    AmazonS3Client s3Client = new AmazonS3Client(); 
    BucketNotificationConfiguration notificationConfiguration = new BucketNotificationConfiguration(); 
    TopicConfiguration topicConfiguration = new TopicConfiguration(snsTopicARN, EnumSet.of(S3Event.ObjectCreated)); 
    notificationConfiguration.addConfiguration("snsTopicConfig", topicConfiguration); 

    String bucketName = "test-bucket"; 

    s3Client.setBucketNotificationConfiguration(bucketName, notificationConfiguration); 
} 

}

但上面的代码引发以下错误

Exception in thread "main" com.amazonaws.services.s3.model.AmazonS3Exception: Unable to validate the following destination configurations (Service: Amazon S3; Status Code: 400; Error Code: InvalidArgument; Request ID: 40F2EB4DB807BD38), S3 Extended Request ID: Cr3P1AZ4FuqHr2UrYBUc5U28uDNh4pWAtqGIRYgDlQsQ5VT4eJ4XK5z0BKdannipxRnEtLyi8jM=

如何得到使用Java API的工作？

我使用python SDK有类似的问题。当您在s3上设置一个触发SNS的事件时，您需要在SNS上添加权限以允许s3触发它。我在代码中没有看到这样做。 我很抱歉我不熟悉java SDK，我不知道究竟需要添加什么，但是在SNS上添加权限应该是正确的方向。
