How right to send Flux or Mono to template (Freemaker)

Question

I got from my repository Flux and in my controller I want to send it to my template. my controller:

 @GetMapping("users")
    public String getAllUser(Model model){

        Flux<User> all = userRepo.findAll();

        model.addAttribute("user", all);
        return "mainpage";
    }

I getting error in my Freemarker's template:

 ${user.content} оr  ${user}

reemarker.core.InvalidReferenceException: The following has evaluated to null or missing: ==> user

Question is, what do you need to call in Java to get the content of the user ? When you write user.content in the template, with the default configuration FreeMarker will try things like user.getContent() , and user.get("content") . But this can be customized, with Configuration.setObjectWrapper . You could extend DefaultObjectWrapper so that it's aware of the Flux API.
