在控制器方法上使用 @Secured 注释时基于 Spring 安全 JDK 的代理问题

Question

我正在做一些 RnD 来学习 Spring Security。在使用方法级别安全性时，我尝试了以下操作：

控制器界面

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

    @RequestMapping("/admin")
    public interface AdminCtrl {

        @RequestMapping(value = { "/get" }, method = { RequestMethod.GET })
        public @ResponseBody
        String getSomething();
    }

控制器实现类

import org.springframework.security.access.annotation.Secured;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@RequestMapping("/admin")
@Controller
public class AdminCtrlImpl implements AdminCtrl {

    @Override
    @RequestMapping(value = "/get", method = RequestMethod.GET)
    @Secured(value = "ROLE_ADMIN")
    public @ResponseBody
    String getSomething() {

        return SecurityContextHolder.getContext().getAuthentication().getName()
                + "==> Responding with HI";
    }

}

    </listener>

</web-app>

但是当我访问 http://localhost:8080/SpringMethodLevelSecurity/admin/get 时，它总是使用匿名用户登录并总是显示：

anonymousUser==> 以 HI 响应。

为什么它没有显示任何身份验证机制屏幕，例如表单登录或 http 登录

附：虽然我知道安全注释主要属于服务层。但我想知道上面的指定情况。

谢谢

你应该插入

<security:intercept-url pattern="/admin/get" access="ROLE_ADMIN"/>

<security:http>标签下如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:security="http://www.springframework.org/schema/security"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-4.0.xsd">

       <security:global-method-security
               secured-annotations="enabled" />
       <security:http>
              <security:form-login />
              <security:intercept-url pattern="/admin/get" access="ROLE_ADMIN"/>
       </security:http>
       <security:authentication-manager>
              <security:authentication-provider>
                     <security:user-service>
                            <security:user name="alpha" authorities="ROLE_ADMIN"
                                           password="password" />
                            <security:user name="beta" authorities="ROLE_USER"
                                           password="password" />
                     </security:user-service>
              </security:authentication-provider>
       </security:authentication-manager>
</beans>

关键是您的系统已准备好执行安全检查，但您没有指定 Spring Security 必须应用安全检查的 url 模式。

事实上，@Secured 注解执行安全检查，但不是直接在 Web 上下文中而是在“应用程序上下文”中，在 Web 上下文中更正确的方法是配置 <security:http>...</security:http> 配置的一部分，换句话说，您的配置不起作用，因为您配置的过滤器在 <security:http>...</security:http>configuration 的基础上起作用 希望对你有帮助
