Method Details

getStorageType

protected StorageType getStorageType()

The storageType of current protocolResolver.

Specified by:

getStorageType in class AbstractAzureStorageProtocolResolver

Returns:

StorageType.BLOB;

listStorageContainers

protected Stream<AbstractAzureStorageProtocolResolver.StorageContainerItem> listStorageContainers(String containerPrefix)

Description copied from class: AbstractAzureStorageProtocolResolver

List all storage containers.

The underlying storage system may support 'prefix' filter, for example, Azure Storage Blob supports this

https://docs.microsoft.com/rest/api/storageservices/list-blobs

In this case, we can avoid load all containers to do client side filtering.

Specified by:

listStorageContainers in class AbstractAzureStorageProtocolResolver

Parameters:

containerPrefix - container name prefix, without any wildcard characters.

Returns:

All storage containers match the given prefix, or all containers if the underlying storage system doesn't support prefix match.

getStorageContainerClient

protected AbstractAzureStorageProtocolResolver.StorageContainerClient getStorageContainerClient(String name)

Description copied from class: AbstractAzureStorageProtocolResolver

Get StorageContainerClient with specified container name.

Specified by:

getStorageContainerClient in class AbstractAzureStorageProtocolResolver

Parameters:

name - Container name

Returns:

the storage container client.

getStorageResource

protected org.springframework.core.io.Resource getStorageResource(String location,
 Boolean autoCreate)

Description copied from class: AbstractAzureStorageProtocolResolver

Get Resource from resource location.

Specified by:

getStorageResource in class AbstractAzureStorageProtocolResolver

Parameters:

location - The specified resource location.

autoCreate - Whether to auto-create the resource if the resource is not exist.

Returns:

the storage Resource.
