org.broadleafcommerce.common.file.service.FileSystemFileServiceProvider

All Implemented Interfaces:

FileServiceProvider

@Service(value="blDefaultFileServiceProvider")
public class FileSystemFileServiceProvider
extends Object
implements FileServiceProvider

Method Detail

getResource

public File getResource(String url)

Description copied from interface: FileServiceProvider

Returns a File representing the passed in url. All separators in the given url should be in URL-separator form meaning '/' rather than '\' (like on Windows).

Specified by:

getResource in interface FileServiceProvider

Returns:

getResource

public File getResource(String url,
               FileApplicationType applicationType)

Description copied from interface: FileServiceProvider

Returns a File representing the passed in name and application type. Providers may choose to cache certain FileApplicationType(s) locally rather than retrieve them from a remote source.

Specified by:

getResource in interface FileServiceProvider

Parameters:

url - - the URL-representation of the resource. This means that paths should always have / separators rather than system-specific values

applicationType - applicationType

Returns:

a File to the

addOrUpdateResources

public void addOrUpdateResources(FileWorkArea area,
                        List<File> files,
                        boolean removeResourcesFromWorkArea)

Description copied from interface: FileServiceProvider

Takes in a work area and application type and moves all of the files to the configured FileProvider.

Specified by:

addOrUpdateResources in interface FileServiceProvider

removeResource

public boolean removeResource(String name)

Description copied from interface: FileServiceProvider

Removes the resource from the file service.

Specified by:

removeResource in interface FileServiceProvider

Parameters:

name - - fully qualified path to the resource

Returns:

true if the resource was removed

buildResourceName

protected String buildResourceName(String url)

Stores the file on the file-system by performing an MD5 hash of the the passed in fileName To ensure that files can be stored and accessed in an efficient manner, the system creates directories based on the characters in the hash. For example, if the URL is /product/myproductimage.jpg, then the MD5 would be 35ec52a8dbd8cf3e2c650495001fe55f resulting in the following file on the filesystem {assetFileSystemPath}/35/ec/myproductimage.jpg. The hash for the filename will include a beginning slash before performing the MD5. This is done largely for backward compatibility with similar functionality in BLC 3.0.0. This algorithm has the following benefits: - Efficient file-system storage with - Balanced tree of files that supports 10 million files If support for more files is needed, implementors should consider one of the following approaches: 1. Overriding the maxGeneratedFileSystemDirectories property from its default of 2 to 3 2. Overriding this method to introduce an alternate approach

Parameters:

url - The URL used to represent an asset for which a name on the fileSystem is desired.

Returns:

getBaseDirectory

protected String getBaseDirectory()

Returns a base directory (unique for each tenant in a multi-tenant installation. Creates the directory if it does not already exist.

getSiteDirectory

protected String getSiteDirectory(String baseDirectory)

Creates a unique directory on the file system for each site. Each site may be in one of 255 base directories. This model efficiently supports up to 65,000 sites served from a single file system based on most OS systems ability to quickly access files as long as there are not more than 255 directories.

Parameters:

The - starting directory for local files which must end with a '/';
