如何解决重定向问题[JSP]

Question

我现在正在使用JSP在Spring中编写Web应用程序，但是重定向存在问题。

当我在编辑个人资料网站中

http://localhost:8080/Kulcz/users/userName/edit

我提交了将我重定向到的表格

http://localhost:8080/Kulcz/users/userName/users/userName

如果我在editPassword网站上更改

action="users/${user.login} to  action="/users/${user.login}

它重定向到

http://localhost:8080/users/userName

提交后，我想要将我重定向回用户个人资料视图：

http://localhost:8080/Kulcz/users/userName/

用户控制器代码：

@Controller
@RequestMapping(value ="users")
public class UserController {

@Autowired
private UserService userService;


@RequestMapping (params ="dodaj")
public String createForm(Model model) {
    model.addAttribute("user", new User());
    return "user/dodaj";
}

@RequestMapping (method = RequestMethod.POST)
public String saveUser(@ModelAttribute("user") @Valid User user, BindingResult result) {
    if(result.hasErrors()) {
        return "user/dodaj";
        }
    userService.saveUser(user);
    return "redirect:/users/"+ user.getLogin();
}

@RequestMapping (value = "/{login}")
public String getUserProfile(@PathVariable String login, Map<String,Object> model) {
    User user = userService.findUser(login);
    model.put("user", user);
    return "user/view";
}

@RequestMapping (value = "/{login}/edit",  method = RequestMethod.GET)
public String editUserPassword(@PathVariable("login") String login,  Map<String,Object> model) {
    User user = userService.findUser(login);
    model.put("user", user);
    return "user/editPassword";
}

@RequestMapping (value = "/{login}", method = RequestMethod.POST)
public String updateUs(@ModelAttribute("user") @Valid User user, BindingResult result) {
    if(result.hasErrors()) {
        return "user/dodaj";
        }
    userService.updateUser(user);
    return "redirect:/users/" + user.getLogin();

}

editPassword.jsp

<form:form name="input" method="post" modelAttribute="user" action="/users/${user.login}">
<form:input type="hidden" path="id"/>
