Package de.hybris.platform.azure.media.storage

Class WindowsAzureBlobStorageStrategy

java.lang.Object

de.hybris.platform.azure.media.storage.WindowsAzureBlobStorageStrategy

All Implemented Interfaces:

MediaStorageInitializer, MediaStorageStrategy

public class WindowsAzureBlobStorageStrategy
extends java.lang.Object
implements MediaStorageStrategy, MediaStorageInitializer

Strategy which allows to store binaries for Media objects in Windows Azure Blob Store data storage.

Corresponding MediaFolder have to be configured with following properties:

 media.folder.{mediaFolderQualifier}.storage.strategy=windowsAzureBlobStorageStrategy
 media.folder.{mediaFolderQualifier}.connection=connectionString
 media.folder.{mediaFolderQualifier}.public.base.url=publicBaseURL
 media.folder.{mediaFolderQualifier}.containerAddress=myContainer
 

Below is full example for MediaFolder with qualifier win:

 media.folder.win.storage.strategy=windowsAzureBlobStorageStrategy
 media.folder.win.connection=DefaultEndpointsProtocol=http;AccountName=foo;AccountKey=UasidIUAIDUAIODuAOIu9kldaldkaIOAKDa89=
 media.folder.win.public.base.url=foo.blob.core.windows.net
 media.folder.win.containerAddress=myContainer
 

If you have more than one media folders, you can share common settings as follows:

 media.globalSettings.windowsAzureBlobStorageStrategy.connection=DefaultEndpointsProtocol=http;AccountName=foo;AccountKey=UasidIUAIDUAIODuAOIu9kldaldkaIOAKDa89=
 media.globalSettings.windowsAzureBlobStorageStrategy.public.base.url=foo.blob.core.windows.net
 media.globalSettings.windowsAzureBlobStorageStrategy.containerAddress=myContainer
 

To control clean on init behavior use following property:

 media.globalSettings.windowsAzureBlobStorageStrategy.cleanOnInit = true / false

Method Detail

store

public StoredMediaData store(MediaStorageConfigService.MediaFolderConfig config,
                             java.lang.String mediaId,
                             java.util.Map<java.lang.String,java.lang.Object> metaData,
                             java.io.InputStream dataStream)

Description copied from interface: MediaStorageStrategy

Stores media data into the storage using unique location identifier. Location identifier is computed by each implementation in different way which depends on API of underlying media storage but in most cases contains a mediaId as unique part. mediaId is generated by platform for each upload attempt so it guarantees uniqueness.

Specified by:

store in interface MediaStorageStrategy

Parameters:

config - media folder configuration

mediaId - the media identifier

metaData - the meta data containing additional possible informations like: original filename, MIME, folder path

dataStream - the data stream to store

Returns:

object containing information about stored data like unique location in the storage, size and hash for location

delete

public void delete(MediaStorageConfigService.MediaFolderConfig config,
                   java.lang.String location)

Description copied from interface: MediaStorageStrategy

Delete media represented by location from the storage.

Specified by:

delete in interface MediaStorageStrategy

Parameters:

config - media folder configuration

location - the string representation of location of media data in storage

getAsStream

public java.io.InputStream getAsStream(MediaStorageConfigService.MediaFolderConfig config,
                                       java.lang.String location)

Description copied from interface: MediaStorageStrategy

Gets the media data from the storage as stream.

Specified by:

getAsStream in interface MediaStorageStrategy

Parameters:

config - media folder configuration

location - the string representation of location of media data in storage

Returns:

the data

getAsFile

public java.io.File getAsFile(MediaStorageConfigService.MediaFolderConfig config,
                              java.lang.String location)

Description copied from interface: MediaStorageStrategy

Gets the media data from the storage as file. Note that implementation of this method may be optional when underlying media storage does not support downloading data as File.

Specified by:

getAsFile in interface MediaStorageStrategy

Parameters:

config - media folder configuration

location - the string representation of location of media data in storage

Returns:

the media as file

getSize

public long getSize(MediaStorageConfigService.MediaFolderConfig config,
                    java.lang.String location)

Description copied from interface: MediaStorageStrategy
