在Spring MVC Controller中获取查询字符串值

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.

Answer 1

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) {
}

Answer 2

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");
}

Answer 3

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");
