Question

Suppose we have this code for login & we want if the credential was for admin page the RequestMapping be for admin & if it was for user credential the user redirect to user panel.
now, the main page of both oppose the same url as I defined in my code below, something like :

http://localhost:8080/project/{username}/main

my question is :

how we can separate these two method in here when they have the same RequestMapping “main” after the login checking finished inside the Controller class?

@RequestMapping(value = "/login")
public String welcome(@RequestParam("j_username") String username, @RequestParam("j_password") String password, HttpSession session, Model model) throws RemoteException, NotBoundException {

    int checkAccount = uiClient.checkAdminAccount(username, password);
    if (checkAccount == 1) {
        session.setAttribute("username", username);
        return "redirect:/" + username + "/main";
    } else if (checkAccount == 0) {
        checkAccount = uiClient.checkAccount(username, password);
        if (checkAccount == 1) {
            session.setAttribute("username", username);
            return "redirect:/" + username + "/main";
        } else if (checkAccount == 0) {
            return "login";
        }
    } else {
        return "databaseError";
    }
    return "login";
}

@RequestMapping(value = "/{username}/main")
public String indexPage(@PathVariable("username") String username) {
    return "/user/userPanel";
}

@RequestMapping(value = "{username}/main")
public String adminIndexPage(@PathVariable("username") String username){
    return "/admin/adminPanel";
}

I mean, is there any way like special tag or something that we can put for each Mapping & separate them after the login process finished so the admin redirect to adminPanel & the user also redirect to userPanel but both with the same url:

http://localhost:8080/project/{username}/main

???

What about this way:

@RequestMapping(value = "/login")
public String welcome(@RequestParam("j_username") String username, @RequestParam("j_password") String password, HttpSession session, Model model) throws RemoteException, NotBoundException {

    int checkAccount = uiClient.checkAdminAccount(username, password);
    if (checkAccount == 1) {
        session.setAttribute("username", username);
        session.setAttribute("userrole", "Admin");
        return "redirect:/" + username + "/main";
    } else if (checkAccount == 0) {
        checkAccount = uiClient.checkAccount(username, password);
        if (checkAccount == 1) {
            session.setAttribute("username", username);
            session.setAttribute("userrole", "Admin");
            return "redirect:/" + username + "/main";
        } else if (checkAccount == 0) {
            return "login";
        }
    } else {
        return "databaseError";
    }
    return "login";
}

@RequestMapping(value = "/{username}/main")
public String indexPage(@PathVariable("username") String username) {
    if ("Admin".equals(session.getAttribute("userrole"))) {
        return "/admin/adminPanel";
    } else {
        return "/user/userPanel";
    }
}

For simplicity, I didn’t use Spring Security to check user role here.
