Class FlowRelativeResourceLoader

java.lang.Object

org.springframework.core.io.DefaultResourceLoader

net.shibboleth.idp.profile.spring.factory.FlowRelativeResourceLoader

All Implemented Interfaces:

ResourceLoader

class FlowRelativeResourceLoader
extends DefaultResourceLoader

This code is extended from org.springframework.webflow.engine.builder.model.FlowRelativeResourceLoader with modifications to support proper lookup of resources via both filesystem and classpath along with custom protocol-specific loaders. This fills a gap for cases where the Spring ResourceLoader itself is fully replaced, versus relying solely on customized behavior in the Spring contexts themselves.

Field Details

flowResource

@Nonnull
private Resource flowResource

Flow resource for relative lookup.

Constructor Details

FlowRelativeResourceLoader

public FlowRelativeResourceLoader(@Nonnull
 Resource resource)

Constructor.

Parameters:

resource - flow resource for relative lookup

Method Details

getClassLoader

public ClassLoader getClassLoader()

Specified by:

getClassLoader in interface ResourceLoader

Overrides:

getClassLoader in class DefaultResourceLoader

getResource

@Nonnull
public Resource getResource(@Nonnull
 String location)

Specified by:

getResource in interface ResourceLoader

Overrides:

getResource in class DefaultResourceLoader

createFlowRelativeResource

@Nonnull
private Resource createFlowRelativeResource(@Nonnull
 String location)

Return resource relative to the flowResource.

Parameters:

location - the resource location

Returns:

a corresponding Resource handle

getResourceByPath

@Nonnull
protected Resource getResourceByPath(@Nonnull
 String path)

Overrides the standard behavior of path-only resources and treats them as file paths if the path exists. Note that this differs from the ordinary Spring contexts that default to file paths because paths are treated as absolute if they are in fact absolute.

Overrides:

getResourceByPath in class DefaultResourceLoader
