java - AWS 多个对象删除

Question

我试图删除多个对象，但它不会删除。我没有遇到任何异常。如果我进行单个删除，则没有问题。

我正在使用以下代码

public void deleteImage(){
        List<KeyVersion> amazonKeys = new ArrayList<KeyVersion>();
        amazonKeys.add(new KeyVersion("compressedc1eac77b-9c38-4036-9770-34a77a163bb0.jpeg"));
        amazonKeys.add(new KeyVersion("compressedb52adf1e-5155-48b6-9051-bb679601f5ee.jpeg"));
        imageService.removeS3Files("mubucketname/dev/3123",amazonKeys);
    }

我的服务是

public void removeS3Files(String bucketName,List<KeyVersion> keys){

        log.debug("deleting multiple objects from s3 with bucket::" + bucketName);
        try{
            DeleteObjectsRequest multiObjectDeleteRequest = new DeleteObjectsRequest(bucketName);
            multiObjectDeleteRequest.setKeys(keys);
            AmazonS3 s3client = new AmazonS3Client(CustomAwsCredentials.getInstance(envConfiguration));
            s3client.setEndpoint(Constant.AWS_ENDPOINT);
            DeleteObjectsResult deleteObjectsResult = s3client.deleteObjects(multiObjectDeleteRequest);
            System.out.println(deleteObjectsResult.getDeletedObjects());
        }catch(AmazonServiceException exception){
            log.debug("Caught an AmazonServiceException.");
            log.debug("Error Message:    " + exception.getMessage());
        }catch (AmazonClientException clientException) {
            log.debug("Caught an AmazonClientException.");
            log.debug("Error Message:    " + clientException.getMessage());
        }
    }

我在存储桶中的数据存储如下所示

bucketname/dev/3123/compressedc1eac77b-9c38-4036-9770-34a77a163bb0.jpeg
bucketname/dev/3123/compressedb52adf1e-5155-48b6-9051-bb679601f5ee.jpeg

我使用下面的代码来删除单个对象(工作正常)

try{
            AmazonS3 s3client = new AmazonS3Client(CustomAwsCredentials.getInstance(envConfiguration));
            System.out.println(s3client.doesBucketExist(bucketName));
            s3client.setEndpoint(Constant.AWS_ENDPOINT);
            s3client.deleteObject(bucketName, key);
        }catch(AmazonServiceException exception){
            log.debug("Caught an AmazonServiceException.");
            log.debug("Error Message:    " + exception.getMessage());
        }catch (AmazonClientException clientException) {
            log.debug("Caught an AmazonClientException.");
            log.debug("Error Message:    " + clientException.getMessage());
        }

请帮助我在多个对象删除中缺少什么？

提前致谢

这不是有效的存储桶名称:

mubucketname/dev/3123

存储桶名称与键分开，您不能将键中的路径前缀放在存储桶名称上。试试这个:

List<KeyVersion> keys = new ArrayList<KeyVersion>();
keys.add(new KeyVersion("dev/3123/compressedc1eac77b-9c38-4036-9770-34a77a163bb0.jpeg"));
keys.add(new KeyVersion("dev/3123/compressedb52adf1e-5155-48b6-9051-bb679601f5ee.jpeg"));
DeleteObjectsRequest request = new DeleteObjectsRequest("mubucketname").withKeys(keys);
DeleteObjectsResult result = s3client.deleteObjects(request);
