FakeS3 putObject没有上传文件

Question

我正在尝试使用FakeS3测试AmazonS3 API。我已按照说明书的说法安装并启动它。当我运行代码时，服务器响应并且日志显示没有错误。存储桶在指定目录中创建。但是，该文件不在目录中。相反，还有另一个名为keyName的目录。此目录中没有文件。我做错了什么？

import com.amazonaws.services.s3.AmazonS3Client;
import com.amazonaws.services.s3.S3ClientOptions;
import com.amazonaws.services.s3.model.PutObjectRequest;

public class FileUpload {
    private static String bucketName     = "bucket1";
    private static String keyName        = "File1";
    private static String uploadFileName = "message.txt";

    public static void main(String[] args){
        //create a new AmazonS3Client object
        BasicAWSCredentials credentials = new BasicAWSCredentials("foo", "bar");
        AmazonS3 client = new AmazonS3Client(credentials);
        client.setEndpoint("http://localhost:10000");
        client.setS3ClientOptions(newS3ClientOptions().withPathStyleAccess(true));
        System.out.println("Creating a new bucket......");
        client.createBucket(bucketName); //create a new bucket
        System.out.println("Uploading text file into specified bucket......");
        File fin = new File(uploadFileName);
        client.putObject(bucketName, keyName, fin); 
        System.out.println("Done");
    }
}
