Example 7 with RequestPath

use of org.springframework.http.server.RequestPath in project spring-framework by spring-projects.

the class ServletRequestPathUtils method parseAndCache.

/**

 * {@link RequestPath} and save it in the request attribute
 * {@link #PATH_ATTRIBUTE} for subsequent use with
 * {@link org.springframework.web.util.pattern.PathPattern parsed patterns}.
 * <p>The returned {@code RequestPath} will have both the contextPath and any
 * servletPath prefix omitted from the {@link RequestPath#pathWithinApplication()
 * pathWithinApplication} it exposes.
 * <p>This method is typically called by the {@code DispatcherServlet} to determine
 * if any {@code HandlerMapping} indicates that it uses parsed patterns.
 * After that the pre-parsed and cached {@code RequestPath} can be accessed
 * through {@link #getParsedRequestPath(ServletRequest)}.
