java.lang.Object org.springframework.core.io.DefaultResourceLoader
public class DefaultResourceLoader
Default implementation of the ResourceLoader
interface.
Used by ResourceEditor
, and serves as base class for
AbstractApplicationContext
.
Can also be used standalone.
Will return a UrlResource
if the location value is a URL,
and a ClassPathResource
if it is a non-URL path or a
"classpath:" pseudo-URL.

public void setClassLoader(ClassLoader classLoader)
null
for using the thread context class loader at the time of actual resource access.
The default is that ClassLoader access will happen using the thread context class loader at the time of this ResourceLoader's initialization.
public ClassLoader getClassLoader()
null
if using the thread context class loader on actual access
(applying to the thread that constructs the ClassPathResource object).
Will get passed to ClassPathResource's constructor for all ClassPathResource objects created by this resource loader.
