Get Query String Values in Spring MVC Controller

Question

I have a referrer URL like this:

http://myUrl.com?page=thisPage&gotoUrl=https://yahoo.com?gotoPage

How do I get the Values of "page" and "gotoUrl" in my Spring Controller?

I want to store these values as variables, so I can reuse them later.

Did you really mean to say "referer"? If so the accepted answer is wrong. — Adam Gent, Jul 30 '13 at 19:55
You should probably URL-encode the value of `gotoUrl` (although I'm not sure it would functionally matter in this particular example). — Max Nanasy, Mar 10 '15 at 20:58

In SpringMVC you can specify values from the query string be parsed and passed in as method parameters with the @RequestParam annotation.

public ModelAndView getPage(
    @RequestParam(value="page", required=false) String page, 
    @RequestParam(value="gotoUrl", required = false) String gotoUrl) {
}

You can use the getParameter() method from the HttpServletRequest interface.

For example;

  public void getMeThoseParams(HttpServletRequest request){
    String page = request.getParameter("page");
    String goToURL = request.getParameter("gotoUrl");
}

This makes sense, if I want to pass the request as an argument. But is there a way to retrieve parameters, if I don't want to pass HttpServletRequest as an Argument to my controller action? – Jake Jul 29 '13 at 22:15

While this answer is technically correct, its not the recommended way to do it with Spring, @Affe's answer is more to the point. – Akshay Jul 30 '13 at 12:19

@AkshaySinghal unless you don't know the parameters in advance but you need a way to handle them - then you can use `request.getParameterNames()` or `request.getParameterMap()` – Lukasz Wiktor Apr 20 '15 at 09:57
@LukaszWiktor I'm sorry I don't understand that comment. It does not seem related to any question or answer. – Akshay Apr 20 '15 at 11:58

@AkshaySinghal I wanted to say that Raunak's answer was helpful. In my case I don't know exact names of the parameters. I need to create an endpoint that can read any parameter. When I noticed this answer I discovered also the 2 methods mentioned in my previous comment. – Lukasz Wiktor Apr 20 '15 at 12:20

Get the QueryString in Spring MVC Controller

This is Liferay portal specific solution, and it works.

Query String Example: ?reportTypeId=1&reportSeqNo=391

In order to get the value of reportSeqNo in Liferay Portal, we need to get the Original Servlet Request.

String reportSeq = PortalUtil.getOriginalServletRequest(PortalUtil.getHttpServletRequest(renderRequest)).getParameter("reportSeqNo");
