java - spring security - 拒绝访问处理程序

Question

我在使用 Spring Security 和让拒绝访问处理程序工作时遇到了一些问题。

Spring Security 正在运行，但是当我在没有所需权限 (ROLE_ADMIN) 的情况下访问/admin 时，Spring Security 只是重定向到根页面，这是我的登录表单页面。

我希望能够将用户重定向到/accessdenied 或/?accessdenied=true 这应该加载登录页面并显示以下消息:“权限被拒绝 - 请登录”

spring-security.xml:

                <security:user name='u' password='u' authorities='ROLE_USER' />
            </security:user-service>
        </security:authentication-provider>

@Controller
public class LoginController {

    private static final Logger logger = LoggerFactory.getLogger(LoginController.class);

    /**
     * Simply selects the home view to render by returning its name.
     */
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String home(Locale locale, Model model) 
    {
        logger.info("Welcome home! The client locale is {}.", locale);

        return "login";
    }

    @RequestMapping(value = "/accessdenied", method = RequestMethod.GET)
    public String accessDenied(Locale locale, Model model) 
    {
        logger.info("Welcome home! The client locale is {}.", locale);

        model.addAttribute("message", "Permission denied - please login");

        return "login";
    }
}

我已经尝试了几个指南，包括以下，但都没有用:

如有任何帮助，我们将不胜感激。

Answer 1

您能否检查日志并确认在您的情况下抛出 AuthenticationException 或在您访问/admin 页面时抛出 AccessDeniedException。

您还访问了没有管理员权限的正确登录名的管理页面，或者您根本没有登录就访问了它？

已编辑:

1. 您能否通过添加一些日志语句来检查或调试当您使用正确的登录名(没有管理员权限)访问/admin 时，是否调用了 accessDenied() 方法？
2. 你也可以分享你的登录jsp，你可能没有正确显示消息参数
3. 当用户没有所需的 priv 但是是有效用户时，将调用 accessDeniedHandler，您可以在调试日志中看到类似的内容

access is denied (user is not anonymous); delegating to AccessDeniedHandler

AccessDeniedHndler 会将请求转发到 errorPage(不是重定向)
