- org.springframework.core.io.support.PathMatchingResourcePatternResolver
- - org.springframework.web.portlet.context.PortletContextResourcePatternResolver

All Implemented Interfaces:
ResourceLoader, ResourcePatternResolver
```
public class PortletContextResourcePatternResolver
extends PathMatchingResourcePatternResolver
```
PortletContext-aware subclass of PathMatchingResourcePatternResolver, able to find matching resources below the web application root directory via Portlet API's PortletContext.getResourcePaths. Falls back to the superclass' file system checking for other resources.
The advantage of using PortletContext.getResourcePaths to find matching files is that it will work in a WAR file which has not been expanded too.

2.0

protected Set<Resource> doFindPathMatchingFileResources(Resource rootDirResource,
                                                        String subPattern)

```
    Overridden version which checks for PortletContextResource and uses PortletContext.getResourcePaths to find matching resources below the web application root directory. In case of other resources, delegates to the superclass version.
    Overrides:
    doFindPathMatchingFileResources in class PathMatchingResourcePatternResolver
    Parameters:
    rootDirResource - the root directory as Resource
    subPattern - the sub pattern to match (below the root directory)
    Returns:
    a mutable Set of matching Resource instances
    Throws:
    IOException - in case of I/O errors

```
    Recursively retrieve PortletContextResources that match the given pattern, adding them to the given result set.
    Parameters:
    portletContext - the PortletContext to work on
    fullPattern - the pattern to match against, with preprended root directory path
    dir - the current directory
    result - the Set of matching Resources to add to
    Throws:
    IOException - if directory contents could not be retrieved
