Forward a POST request with additional params - spring

Question

Is there a way to forward a POST request from one controller to another with additional param(s)?
Let's say I have a form like this:
<form action"${contextPath}/controller1/post">
<input name="field1" type="text"/>
<input name="field2" type="text"/>
<input value="submit" type="submit"/>
</form>
This form will post to controller1.post() method.
But now I have another controller - controller2 also with a post method.
I now want to post to controller2.post so I could add some parameters to the request before forwarding to controller1.
Is there a way to do this?

You can try that if this is what you are looking for
#RequestMapping(value = "/controller1/{id}", method = RequestMethod.Post)
public void doSomething(
#PathVariable Long id,
HttpServletRequest request,
HttpServletResponse response) {
request.setAttribute("id",Id);
RequestDispatcher rd = request.getRequestDispatcher("your url/controller2");
rd.forward(request, response);
}
And after in controller2
#RequestMapping(value = "/controller2", method = RequestMethod.Post)
public string doSomething2(Model model,
HttpServletRequest request,
HttpServletResponse response) {
model.addAttribute("id", request.getAttribute("id"));
return "myView";
}
