java - 使用 Jets3t 在 s3 上获取存储桶列表时出现异常

Question

我正在尝试使用 S3 服务从所有存储桶中检索列表。执行此操作时出现异常。

我收到 S3 服务异常:java.lang.Long 无法转换为 java.lang.Integer。

代码如下:

    String awsKey = "awskey";
    String awsSecret = "secret";
    AWSCredentials aws = new AWSCredentials(awsKey,awsSecret);

    //communicate with s3
    try{
    S3Service service = new RestS3Service(aws);

    //get buckets
    S3Bucket[] buckets = service.listAllBuckets();

这是堆栈跟踪:

任何帮助，将不胜感激。谢谢。

这是 http 客户端的问题，必须使用旧版本。

正在使用 4.3.1 ，必须使用 4.2。
