java - JetS3t - 连接无异常，但当我尝试执行其他操作时为 "Invalid Class Name"

Question

我似乎能够正常连接，因为新的 RestS3Service 不会抛出异常。

但是，当我尝试执行 getBucket("name") 之类的操作时，我得到:无效的类名:org.jets3t.service.utils.RestUtils$ConnManagerFactory嗯>

知道如何解决这个问题吗？

谢谢!

我的代码:

    AWSCredentials awsCredentials = new AWSCredentials(awsAccessKey, awsSecretKey);
    S3Service s3Service = null;

    System.out.println("Credentials created, trying Service");

    try {
        s3Service = new RestS3Service(awsCredentials);
    } catch (S3ServiceException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    System.out.println("Service connected, trying bucket grab");

    try {
        S3Bucket bucket = s3Service.getBucket("mrbucket");
        System.out.println("bucket grabbed: "+bucket.getName());
    } catch (S3ServiceException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

输出:

Credentials created, trying Service

Installer - Installer service created

Service connected, trying bucket grab

您的类路径中似乎缺少 org.jets3t.service.utils.RestUtils$ConnManagerFactory.class。您有完整的 JetS3t 库吗？库中大约有19个jar，RestUtils$ConnManagerFactory.class在0.8.1a版本的jet3t-0.8.1a.jar中。
