Question

Suppose I have a Java servlet that I want to use for two (or more) different url-patterns:

  <servlet-mapping>
    <servlet-name>MyServlet</servlet-name>
    <url-pattern>/this/exact/path</url-pattern>
  </servlet-mapping>

  <servlet-mapping>
    <servlet-name>MyServlet</servlet-name>
    <url-pattern>/that/prefix/path/*</url-pattern>
  </servlet-mapping>

  <servlet-mapping>
    <servlet-name>MyServlet</servlet-name>
    <url-pattern>/yet/another/exact/path</url-pattern>
  </servlet-mapping>

MyServlet will be called for any of:

/this/exact/path
/yet/another/exact/path
/that/prefix/path/param1
/that/prefix/path/param2.html

what I want to know is how can I tell from inside my code what was the path for which the request was matched for . (i.e. if the request was made to /myapp/yet/another/exact/path i want to get the string /yet/another/exact/path).

I guess also that there should be a way to differentiate between the /that/prefix/path/ and what ever was matched with the * It would be nice if someone could tell me how this should be done.

I tried String path = req.getRequestURI() but it also returns the /myapp part.

Answer 1

HttpServletRequest.getServletPath() returns the URL pattern excluding /*, and HttpServletRequest.getPathInfo() returns the part matched by /* (or null for exact match).
