Question

I have spring intrecpetor (implements org.springframework.web.servlet.handler.HandlerInterceptorAdapter), that redirects to login facebbok page, after that I need to redirect to exact same location.

What’s the best / fail proof / way to do that

I need to extract request String from HttpServletRequest and put in in the after login redeirect back URL

I’m not shure if

WEB_ROOT + request.getContextPath() + "?" + request.getQueryString()

is the right solution.

Answer 1

try the following:

public static String getUrl(HttpServletRequest req) {
String reqUrl = req.getRequestURL().toString();
String queryString = req.getQueryString();
if (queryString != null) {
    reqUrl += "?"+queryString;
}
return reqUrl;

}
