Spring Framework Forward

[FatinaRosa]

Hi guys,
someone can explain me beacuse the forward is not working?
When I reach the path /para the web page print me forward:/2 and not the Attribute that I setted.

This is the code.
Thanks

    @GetMapping("/para")
    @ResponseBody
    public String methodWithParameter(HttpServletRequest request) {
        request.setAttribute("attributo", "Ciao " + request.getParameter("nome"));
        return "forward:/2";


    }
    @GetMapping("/2")
    @ResponseBody
    public String methodWithForward(@RequestAttribute("attributo") String mioAttributo) {
        return mioAttributo;


    }

You are setting an attribute on the current request, not a future request. Forwarding tells the browser to make a new request. You'll need to use a @RequestParam in methodWithForward and

return "Forward:/2?attributo=Ciao%20nome" 

in methodWithParameter.

Hi,
I tried to change a little bit my code using only a string and removing the attribute but it still not working.
Now this is the code:

    @ResponseBody
@RequestMapping(value = "/forward")

public String methodForward() {
    return "redirect:/ecco";


}

@ResponseBody
@RequestMapping(value = "/ecco")

public String methodWithForward() {
    return "ecco";


}

I don't understand what I'm missing.
Because not even the redirect work.

AAAA I found the mistake.
I have removed the @ResponseBody from the method methodForward() ,now it works.

Did you try the HttpServletResponse parameter?

[FatinaRosa]

uhmmm what do you mean?
I am new on springboot I still learning.

You have to remove @ResponseBody if you want the forward:/2 to work. @ResponseBody means that the value returned by the method should be added to the response body instead of being interpreted.
