    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.

Field Summary
`static 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.

Field Detail

### 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.

Method Detail

### 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
