如何使用jets3t访问S3？

嗨，我试图访问S3使用jets3t库。我只是其次AWS支持的示例代码（here's url）这里是我的简单的代码如何使用jets3t访问S3？

import org.jets3t.service.S3Service; 
import org.jets3t.service.S3ServiceException; 
import org.jets3t.service.impl.rest.httpclient.RestS3Service; 
import org.jets3t.service.model.S3Bucket; 
import org.jets3t.service.security.AWSCredentials; 

public class Test1 { 

    /** 
    * @param args 
    */ 
public static void main(String[] args) { 
    // TODO Auto-generated method stub 

    String awsAccessKey = "******************"; 
    String awsSecretKey = "*********************************"; 

    System.out.println("0"); 
    AWSCredentials awsCredentials = new AWSCredentials(awsAccessKey, awsSecretKey); 

    try{ 
    S3Service s3Service = new RestS3Service(awsCredentials); 

    System.out.println("1"); 

    S3Bucket testBucket = s3Service.getOrCreateBucket("first_test_bucket"); 
    System.out.println("Created test bucket: " + testBucket.getName()); 

    S3Bucket[] myBuckets = s3Service.listAllBuckets(); 

    System.out.println("2"); 

    System.out.println("How many buckets to I have in S3? " + myBuckets.length); 

    System.out.println("3"); 

    } 
    catch (Exception e){ 

     System.out.println("exception: " + e.toString()); 

    } 

}

}

但我遇到了一个问题，这样的

我想这因为我在我的公司处理了这段代码，所以是一个关于防火墙的问题。有人知道这个问题吗？帮帮我！

我希望访问密钥和密钥是假的... – 2011-04-06 06:52:29

你的密钥在这篇文章的旧版本中仍然可见。您最好删除整个线程或更好地登录到Amazon AWS并尽快更改您的凭据。 – 2011-04-06 09:32:51

在你的 - 不那么容易阅读 - 日志中有一些“连接超时：连接异常：...”。所以，是的，这可能是因为您在代理后面（Amazon S3 Rest服务在端口443上侦听）。

您可能想要配置JetS3t以使用代理。创建jets3t.properties属性文件并添加以下属性：

httpclient.proxy-host=your proxy host 
httpclient.proxy-port=your proxy port 
httpclient.proxy-user=proxy user 
httpclient.proxy-password=password

而且，请注意，有一个莫名其妙稳定S3测试桩，您可以使用来进行测试： https://github.com/technoweenie/parkplace

非常感谢，卢西亚诺先生，也为您的建议！这是我的错误，暴露了我的秘密，访问密钥！我已经删除了密钥！而我解决了这个代理问题，虽然我徘徊了一些问题，如添加属性到eclipse项目！ – truelifer 2011-04-07 00:55:42

你需要设置一个文本文件格式的JetS3t配置和给予的JetS3t类属性如下：

Jets3tProperties jets3=new Jets3tProperties(); 
jets3.loadAndReplaceProperties(new FileInputStream("/root/Desktop/jets3t.properties"), "jets3t.properties");
