Example 36 with HandlerExecutionChain

use of org.springframework.web.servlet.HandlerExecutionChain in project spring-framework by spring-projects.

the class AbstractUrlHandlerMapping method buildPathExposingHandler.

	 * handler, the {@link #PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE}, as well as
	 * the {@link #URI_TEMPLATE_VARIABLES_ATTRIBUTE} before executing the handler.
	 * <p>The default implementation builds a {@link HandlerExecutionChain}
	 * with a special interceptor that exposes the path attribute and uri template variables
	 * @param rawHandler the raw handler to expose
	 * @param pathWithinMapping the path to expose before executing the handler
	 * @param uriTemplateVariables the URI template variables, can be {@code null} if no variables found
	 * @return the final handler object
