You could do this way , consider i am passing the ${id} value through the query string 

<a href="user?id=${id}">Get User</a>

And in your controller,

@RequestMapping ("user")
    public String getStudent(@RequestParam  Integer id, Model model){
        User savedUser = userRepository.get(id);
        model.addAttribute("user", savedUser);
        return "user";
    }

Hope this helps !
