Spring Security 方法级别安全注释不起作用

Question

我正在使用 Struts 2 + Spring Security 3 制作一个简单的 Web 应用程序。我想使用 Pre-Post Annotations 来实现方法级安全性。

但是注释不起作用。

这是我的 web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>MyCustomSpringSecurity</display-name>

  <context-param>
<param-name>contextConfiguration</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
  </context-param>

  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

  <filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

  <filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
  <filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>

  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
  <welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

这是我的 struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<package name="default" extends="struts-default">
    <action name="firstPage" class="code.action.MyAction" method="showPage">
        <result name="success">/firstPage.jsp</result>
    </action>
</package>
</struts>

这是我的 applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd">

    <global-method-security pre-post-annotations="enabled" >
    </global-method-security>

    <beans:bean id="myAction" class="code.action.MyAction">
        <intercept-methods>
            <protect access="ROLE_ADMIN" method="showPage"/>
        </intercept-methods>
    </beans:bean>

    <http auto-config="true" use-expressions="true">
        <intercept-url pattern="/index.jsp" access="permitAll" />
        <intercept-url pattern="/firstPage" access="hasRole('ROLE_USER')" />
    </http>

    <authentication-manager>
        <authentication-provider>
            <user-service>
                <user name="user" password="user" authorities="ROLE_USER" />
            </user-service>
        </authentication-provider>
    </authentication-manager>

</beans:beans>

最后这是MyAction.java

package code.action;

import org.springframework.security.access.prepost.PreAuthorize;

public class MyAction {
    @PreAuthorize("hasRole('ROLE_ADMIN')")
    public String showPage(){
        System.out.println("in showPage");
        return "success";
    }
}

您可以清楚地看到，我为用户分配的角色是 ROLE_USER 但我希望在访问该方法时它是 ROLE_ADMIN，因此从逻辑上讲，运行此代码时应该出现 403 Access Denied 错误。但它能够访问该方法并显示下一页。

所以我认为注释不起作用。

有人知道发生了什么事吗？

为了使 Spring 注释在 Struts 2 操作中有意义，您必须使用 Struts 2 Spring Plugin 。这将使用 Spring 实例化 Struts 2 对象，允许注释处理、注入(inject)等。
