無法在Java中以Amazon S3上傳文件

我是一名使用S3的初學者，我想用它來存儲我的計算機的某些文件。我寫了在Java小程序，它會將我的所有文件和文件夾，但我有這樣的例外：無法在Java中以Amazon S3上傳文件

我相信我提供了正確的憑據SDK。我使用了以前的程序中的相同憑據來進行測試，並且工作正常。我可以創建桶，但我無法存儲對象。在我的代碼中，我使用PutObjectRequest來存儲對象。

以下是我的init我的亞馬遜S3對象：

AmazonS3 s3 = new AmazonS3Client(new PropertiesCredentials(
      S3Export.class      .getResourceAsStream("AwsCredentials.properties")));

上載代碼：

private void parseDirectory(File fin, File fdefault, String out) 
      throws FileNotFoundException { 

     System.out.println("processing .." + fin.getName()); 

     File[] files = fin.listFiles(); 

     PrintWriter pw = new PrintWriter(fdefault); 

     for (File f : files) { 

      String key = UUID.randomUUID().toString(); 

      String name = ""; 

      PutObjectRequest por = null; 

      if (f.isDirectory()) { 

       name = "d_" + f.getName() + ".properties"; 

       File metadata = new File(out + name); 

       parseDirectory(f, metadata, out); 

       pw.println(key + "=" + name); 

       //upload to s3 
       por = new PutObjectRequest(this.bucketName, key, metadata); 

      } else { 

       name = f.getName(); 

       pw.println(key + "=" + name); 

       por = new PutObjectRequest(this.bucketName, key, f); 

      } 


      this.amazonS3.putObject(por); 
     } 
     pw.close(); 
    }

我的代碼在這一行失敗：this.amazonS3.putObject(por);。

有人可以解釋我的代碼有什麼問題。

我終於找到了我的問題anwer。事實是在初始化時，我傳遞了一個錯誤的存儲桶名稱，並且我正在使用不同的名稱來提出請求。就這樣。

請記住，您始終可以使用eclipse aws sdk生成示例項目，並瞭解與S3，SimpleDB等的交互如何工作。 – Kris 2012-02-01 10:02:48
