Class SpringResourceLoader

java.lang.Object

org.apache.velocity.runtime.resource.loader.ResourceLoader

net.shibboleth.ext.spring.velocity.SpringResourceLoader

public class SpringResourceLoader
extends org.apache.velocity.runtime.resource.loader.ResourceLoader

Velocity ResourceLoader adapter that loads via a Spring ResourceLoader. Used by VelocityEngineFactory for any resource loader path that cannot be resolved to a java.io.File.

Note that this loader does not allow for modification detection: Use Velocity's default FileResourceLoader for java.io.File resources.

Expects "spring.resource.loader" and "spring.resource.loader.path" application attributes in the Velocity runtime: the former of type org.springframework.core.io.ResourceLoader, the latter a String.

Since:

6.0.0
