Question

假设我们有此登录代码和＆amp;我们想要的是，如果凭证是针对管理页面的，则RequestMapping是针对admin＆amp;如果是用户凭证，则用户重定向到用户面板。现在，两者的主页都反对我在下面的代码中定义的相同URL，如：

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

我的问题是：

如果在Controller类中完成登录检查后它们具有相同的RequestMapping“main”，我们如何将这两个方法分开？

@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";
}

我的意思是，有没有像我们可以为每个Mapping＆amp; amp;在登录过程完成后将它们分开，以便管理员重定向到adminPanel＆amp;用户还重定向到userPanel，但两者都使用相同的URL：

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

???

这样：

@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";
    }
}

为简单起见，我没有使用Spring Security来检查用户角色。

Spring MVC绑定到同一个@RequestMapping
