 * A strategy for assigning a name to a handler method's mapping.

 * AbstractHandlerMethodMapping}. It is used to assign a name to the mapping of
 * every registered handler method. The names can then be queried via
 * {@link org.springframework.web.servlet.handler.AbstractHandlerMethodMapping#getHandlerMethodsForMappingName(String)
 * AbstractHandlerMethodMapping#getHandlerMethodsForMappingName}.

 * <p>Applications can build a URL to a controller method by name with the help
 * of the static method
 * {@link org.springframework.web.servlet.mvc.method.annotation.MvcUriComponentsBuilder#fromMappingName(String)
 * MvcUriComponentsBuilder#fromMappingName} or in JSPs through the "mvcUrl"
 * function registered by the Spring tag library.
