Spring is working with the information how the servlet mapping is defined. If you are using suffix mapping (*.something), then Spring uses just the first part (without the suffix). This means you shuold map just /index in your url-pattern (without the suffix).

JavaDoc in Spring's UrlPathHelper#getPathWithinServletMapping gives a better description what is being used in the mapping process:

Return the path within the servlet mapping for the given request, i.e. the part of the request's URL beyond the part that called the servlet, or "" if the whole URL has been used to identify the servlet.

Detects include request URL if called within a RequestDispatcher include.

E.g.: servlet mapping = "/test/*"; request URI = "/test/a" -> "/a".

E.g.: servlet mapping = "/test"; request URI = "/test" -> "".

E.g.: servlet mapping = "/*.test"; request URI = "/a.test" -> "".
