Method Detail

doFindPathMatchingFileResources

protected java.util.Set<Resource> doFindPathMatchingFileResources(Resource rootDirResource,
                                                                  java.lang.String subPattern)
                                                           throws java.io.IOException

Overridden version which checks for ServletContextResource and uses ServletContext.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:

java.io.IOException - in case of I/O errors

doRetrieveMatchingServletContextResources

protected void doRetrieveMatchingServletContextResources(ServletContext servletContext,
                                                         java.lang.String fullPattern,

                                                         java.util.Set<Resource> result)
                                                  throws java.io.IOException

Recursively retrieve ServletContextResources that match the given pattern, adding them to the given result set.

Parameters:

servletContext - the ServletContext 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:

java.io.IOException - if directory contents could not be retrieved
