Question

使用S3服务我试图从所有桶中检索列表。虽然我这样做但我得到了例外。

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

以下是代码：

    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。感谢。

Answer 1

这是http客户端的问题，不得不使用旧版本。

使用4.3.1时，不得不使用4.2。

Answer 2

此问题已修复，但尚未发布（HTTPCLIENT-1418）。在Apache HttpComponents HttpClient的4.3.2版中查找修复程序。
