Spring security spring security中的表单登录不'；行不通

我在表单登录中遇到了Spring安全性问题：即使我给他们提供了路径，他们也找不到URL登录

<form-login login-page="/login"  default-target-url="/index"  />

这是控制器：

@Controller
public class LoginController{

            @RequestMapping("/login")
            public String doLogin() {
                return "login";
            }
}

这是spring-security.xml

编辑1：基于用户输入

更改以下行

<intercept-url pattern="/**" access="isAuthenticated()"/>

沿着这条线的东西

或

基本上去掉isAuthenticated（），因为读取XML配置时很少有人会遇到问题

让我知道它是否修复了它

额外示例：

您是否尝试清除缓存？是@yassine\uuuo:\但没有任何更改。请向我们显示您的安全代码配置以及安全控制器（如果您有）。@Aeseir我已编辑我的问题，请提供帮助？？无法计算表达式“USER\u ADMIN”！！我已经编辑了新的截取url。如果我是你，我会放弃xml，转而使用java配置。就我个人而言，我讨厌XML。

<intercept-url pattern="/**" access="isAuthenticated()"/>

<intercept-url pattern="/**" access="hasRole('USER_ADMIN')"/>
