使用java将文件上传到Amazon S3失败 - sun.security.validator.ValidatorException

时间：2016-10-26 08:13:03

标签： java eclipse amazon-s3

我正在使用 eclipse 并在 java中编写了一个方法来将文件上传到amazon s3 。它从主要方法成功上传。从eclipse我从debug透视图中复制了等效的命令并在命令提示符下运行，它的工作正常。我在项目和打包的jar文件中添加了代码的那部分。当我在jar文件中调用该函数时抛出

sun.security.validator.ValidatorException：PKIX路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException：无法找到所请求目标错误的有效证书路径。

我在eclipse中指出的所有依赖jar文件，同样我在打包的jar文件中指出。 Stil它没有用。

上传到亚马逊s3的方法

public static boolean saveFileToS3(File f, Long contentLength, String s3Name, String bucketName,String accessKey, String secretKey) throws FileNotFoundException, IllegalArgumentException, IOException, InterruptedException {

    AmazonS3 s3Client = null;
    try {
        AWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
        s3Client = new AmazonS3Client(credentials);
    } catch (Exception e1) {
        e1.printStackTrace();
        return false;
    }        

    List<PartETag> partETags = new ArrayList<PartETag>();
    InitiateMultipartUploadRequest initRequest = new InitiateMultipartUploadRequest(bucketName, s3Name);
    ObjectMetadata metadata = new ObjectMetadata();
    metadata.setContentLength(contentLength);

    initRequest.setObjectMetadata(metadata);
    initRequest.withCannedACL(CannedAccessControlList.PublicRead);
    InitiateMultipartUploadResult initResponse = null;
    try {
        initResponse = s3Client.initiateMultipartUpload(initRequest);
        if(initResponse == null){
            return false;
        }
    } catch (AmazonServiceException e) {
        e.printStackTrace();
    } catch (AmazonClientException e) {
        e.printStackTrace();
    } catch (Exception e){
        return false;
    }
    long partSize = 10485760; // Set part size to 10 MB.
    try {
        long filePosition = 0;
        for (int i = 1; filePosition < contentLength; i++) {
            partSize = Math.min(partSize, (contentLength - filePosition));

            if(initResponse == null){
                return false;
            }

            UploadPartRequest uploadRequest = new UploadPartRequest().withBucketName(bucketName).withKey(s3Name).withUploadId(initResponse.getUploadId()).withPartNumber(i).withFileOffset(filePosition).withFile(f).withPartSize(partSize);

            partETags.add(s3Client.uploadPart(uploadRequest).getPartETag());

            filePosition += partSize;
        }
        CompleteMultipartUploadRequest compRequest = new CompleteMultipartUploadRequest(bucketName, s3Name, initResponse.getUploadId(), partETags);

        s3Client.completeMultipartUpload(compRequest);
        System.out.println("Upload complete.");
    } catch (AmazonClientException amazonClientException) {
        s3Client.abortMultipartUpload(new AbortMultipartUploadRequest(bucketName, s3Name, initResponse.getUploadId()));
        amazonClientException.printStackTrace();
        f.delete();
        return false;
    }
    f.delete();
    return true;
}

我已经包含了亚马逊s3上传功能所需的这四个罐子。 AWS-Java的SDK-1.7.8.1.jar 杰克逊的注解 - 2.1.2.jar 杰克逊核心2.2.3.jar 杰克逊 - 数据绑定-2.1.2.jar

这是我用来从main方法

我的问题是，

  1. 当我从eclipse main方法运行时，我能够上传，当我从命令提示符运行时，我能够上传。但是当我在jar中打包时，相同的代码失败了，即使我在类路径中也添加了所有jar。为什么呢？

  2. 如何修复此错误？

2 个答案:

答案 0 :(得分：0)

默认情况下，Java附带一组非常有限的根CA证书，问题是您的运行系统中缺少amazon s3 ca证书

答案 1 :(得分：0)

你能提到用来触发main方法的命令吗？问题清楚地表明您遇到了握手异常，因此我假设在通过您的命令运行jar时证书路径无效。
