org.springframework.core.io.ClassPathResource
public class ClassPathResource
Resource implementation for class path resources.
Uses either a given ClassLoader or a given Class for loading resources.
Supports resolution as java.io.File if the class path
resource resides in the file system, but not for resources in a JAR.
Always supports resolution as URL.

| Method Summary | |
|---|---|
Resource |
createRelative(String relativePath)
This implementation creates a ClassPathResource, applying the given path relative to the path of the underlying resource of this descriptor. |
boolean |
equals(Object obj)
This implementation compares the underlying class path locations. |
ClassLoader |
getClassLoader()
Return the ClassLoader that this resource will be obtained from. |
String |
getDescription()
This implementation returns a description that includes the class path location. |
File |
getFile()
This implementation returns a File reference for the underlying class path resource, provided that it refers to a file in the file system. |
protected File |
getFileForLastModifiedCheck()
This implementation determines the underlying File (or jar file, in case of a resource in a jar/zip). |
String |
getFilename()
This implementation returns the name of the file that this class path resource refers to. |
InputStream |
getInputStream()
This implementation opens an InputStream for the given class path resource. |
String |
getPath()
Return the path for this resource (as resource path within the class path). |
URL |
getURL()
This implementation returns a URL for the underlying class path resource. |
int |
hashCode()
This implementation returns the hash code of the underlying class path location. |
