Getpathinfo returns null

Why in normal servlet request. I know i can use PathVariable , but wonder why the results of this method is the difference? In case of Spring the servlet path is the full path hence if you call getServletPath it will always return the full URI and getPathInfo will return nothing.

This should certainly be marked as the correct answer by now. This great, Thanks. The thing is, I have this filter used by many different app, some spring boot, others not. So, I need to make a distinction in the filter between the request coming from spring boot or not. String getPathInfo Returns any extra path information associated with the URL the client sent when it made this request.

String getPathTranslated Returns any extra path information after the servlet name but before the query string, and translates it to a real path. String getRemoteUser Returns the login of the user making this request, if the user has been authenticated, or null if the user has not been authenticated.

HttpSession getSession Returns the current session associated with this request, or if the request does not have a session, creates one. HttpSession getSession boolean create Returns the current HttpSession associated with this request or, if there is no current session and create is true, returns a new session.

Principal getUserPrincipal Returns a java. Principal object containing the name of the current authenticated user. As of Version 2. String role Returns a boolean indicating whether the authenticated user is included in the specified logical "role". String username, java. String password Validate the provided username and password in the password validation realm used by the web container login mechanism configured for the ServletContext. Methods inherited from interface javax. All servlet containers support basic, form and client certificate authentication, and may additionally support digest authentication.

If the servlet is not authenticated null is returned. This method returns null if no cookies were sent. Returns: an array of all the Cookies included with this request, or null if the request has no cookies getDateHeader long getDateHeader java. Use this method with headers that contain dates, such as If-Modified-Since.

The date is returned as the number of milliseconds since January 1, GMT. The header name is case insensitive. If the request did not have a header of the specified name, this method returns If the header can't be converted to a date, the method throws an IllegalArgumentException.

Parameters: name - a String specifying the name of the header Returns: a long value representing the date specified in the header expressed as the number of milliseconds since January 1, GMT, or -1 if the named header was not included with the request Throws: IllegalArgumentException - If the header value can't be converted to a date getHeader java. If the request did not include a header of the specified name, this method returns null.

If there are multiple headers with the same name, this method returns the first head in the request. You can use this method with any request header. Parameters: name - a String specifying the header name Returns: a String containing the value of the requested header, or null if the request does not have a header of that name getHeaders java.

Some headers, such as Accept-Language can be sent by clients as several headers each with a different value rather than sending the header as a comma separated list. If the request did not include any headers of the specified name, this method returns an empty Enumeration. Parameters: name - a String specifying the header name Returns: an Enumeration containing the values of the requested header.

If the request does not have any headers of that name return an empty enumeration. If the container does not allow access to header information, return null getHeaderNames java. If the request has no headers, this method returns an empty enumeration. Some servlet containers do not allow servlets to access headers using this method, in which case this method returns null Returns: an enumeration of all the header names sent with this request; if the request has no headers, an empty enumeration; if the servlet container does not allow servlets to use this method, null getIntHeader int getIntHeader java.

If the request does not have a header of the specified name, this method returns If the header cannot be converted to an integer, this method throws a NumberFormatException. Parameters: name - a String specifying the name of a request header Returns: an integer expressing the value of the request header or -1 if the request doesn't have a header of this name Throws: java. NumberFormatException - If the header value can't be converted to an int getMethod java.

Returns: a String specifying the name of the method with which this request was made getPathInfo java. This method returns null if there was no extra path information. Returns: a String , decoded by the web container, specifying extra path information that comes after the servlet path but before the query string in the request URL; or null if the URL does not have any extra path information getPathTranslated java. If the URL does not have any extra path information, this method returns null or the servlet container cannot translate the virtual path to a real path for any reason such as when the web application is executed from an archive.

The web container does not decode this string. Returns: a String specifying the real path, or null if the URL does not have any extra path information getContextPath java. The context path always comes first in a request URI. For servlets in the default root context, this method returns "". The container does not decode this string. It is possible that a servlet container may match a context by more than one context path. In such cases this method will return the actual context path used by the request and it may differ from the path returned by the ServletContext.

The context path returned by ServletContext. This method returns null if the URL does not have a query string. Returns: a String containing the query string or null if the URL contains no query string.

The value is not decoded by the container. Whether the user name is sent with each subsequent request depends on the browser and type of authentication.
