    public class BeanNameUrlHandlerMapping

extends AbstractDetectingUrlHandlerMapping

Implementation of the `HandlerMapping` interface that map from URLs to beans with names that start with a slash ("/"), similar to how Struts maps URLs to action names.

This is the default implementation used by the `DispatcherServlet`, along with `DefaultAnnotationHandlerMapping` (on Java 5 and higher). Alternatively, `SimpleUrlHandlerMapping` allows for customizing a handler mapping declaratively.

The mapping is from URL to bean name. Thus an incoming URL "/foo" would map to a handler named "/foo", or to "/foo /foo2" in case of multiple mappings to a single handler. Note: In XML definitions, you'll need to use an alias name="/foo" in the bean definition, as the XML id may not contain slashes.

Supports direct matches (given "/test" -> registered "/test") and "*" matches (given "/test" -> registered "/t*"). Note that the default is to map within the current servlet mapping if applicable; see the `"alwaysUseFullPath"` property for details. For details on the pattern options, see the `AntPathMatcher` javadoc.
