Interface ResourcePatternResolver
- All Superinterfaces:
- ResourceLoader
- All Known Subinterfaces:

- All Known Implementing Classes:
- AbstractApplicationContext, AbstractRefreshableApplicationContext, AbstractRefreshablePortletApplicationContext, AbstractRefreshableWebApplicationContext, AbstractXmlApplicationContext, ClassPathXmlApplicationContext, FileSystemXmlApplicationContext, GenericApplicationContext, GenericWebApplicationContext, PathMatchingResourcePatternResolver, PortletContextResourcePatternResolver, ServletContextResourcePatternResolver, StaticApplicationContext, StaticPortletApplicationContext, StaticWebApplicationContext, XmlPortletApplicationContext, XmlWebApplicationContext
public interface ResourcePatternResolver
- extends ResourceLoader
Strategy interface for resolving a location pattern (for example, an Ant-style path pattern) into Resource objects.
This is an extension to the ResourceLoader
interface. A passed-in ResourceLoader (for example, an
ApplicationContext passed in via
ResourceLoaderAware when running in a context)
can be checked whether it implements this extended interface too.
PathMatchingResourcePatternResolver is a standalone implementation
that is usable outside an ApplicationContext, also used by
ResourceArrayPropertyEditor for populating Resource array bean properties.
Can be used with any sort of location pattern (e.g. "/WEB-INF/*-context.xml"): Input patterns have to match the strategy implementation. This interface just specifies the conversion method rather than a specific pattern format.
This interface also suggests a new resource prefix "classpath*:" for all matching resources from the class path. Note that the resource location is expected to be a path without placeholders in this case (e.g. "/beans.xml"); JAR files or classes directories can contain multiple files of the same name.

CLASSPATH_ALL_URL_PREFIX
static final String CLASSPATH_ALL_URL_PREFIX
- Pseudo URL prefix for all matching resources from the class path: "classpath*:"
This differs from ResourceLoader's classpath URL prefix in that it
retrieves all matching resources for a given name (e.g. "/beans.xml"),
for example in the root of all deployed JAR files.

getResources
Resource[] getResources(String locationPattern) throws IOException
- Resolve the given location pattern into Resource objects.
Overlapping resource entries that point to the same physical resource should be avoided, as far as possible. The result should have set semantics.
- Parameters:
locationPattern- the location pattern to resolve- Returns:
- the corresponding Resource objects
- Throws:
IOException- in case of I/O errors
