## Class SpringResourceLoader

- java.lang.Object
- - org.apache.velocity.runtime.resource.loader.ResourceLoader
  - - org.springframework.ui.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.
