spring-mvc - Spring Security 忽略具有方法级安全性的访问拒绝处理程序

Question

我正在使用 Spring 3.2.4 并且无法让 Spring Security 重定向到我的 access-denied-handler使用基于注解的方法级别安全性时。我找到了几篇关于此的不同帖子，但到目前为止，我似乎没有找到任何解决方案。

我的 security.xml 文件:

<!-- need this here to be able to secure methods in components other than controllers (as scanned in applicationContext.xml) -->
<global-method-security secured-annotations="enabled" pre-post-annotations="enabled" jsr250-annotations="enabled" ></global-method-security>

<!-- Annotation/JavaConfig examples http://stackoverflow.com/questions/7361513/spring-security-login-page -->
<http use-expressions="true" entry-point-ref="authenticationEntryPoint">
    <access-denied-handler ref="accessDeniedHandler"/>

    <intercept-url pattern="/secure/login" access="permitAll" />
    <intercept-url pattern="/secure/logout" access="permitAll" />
    <intercept-url pattern="/secure/denied" access="permitAll" />
    <session-management session-fixation-protection="migrateSession" session-authentication-error-url="/login.jsp?authFailed=true"> 
        <concurrency-control max-sessions="10" error-if-maximum-exceeded="true" expired-url="/login.html" session-registry-alias="sessionRegistry"/>
    </session-management>

    <intercept-url pattern="/**" access="isAuthenticated()" />
    <form-login  default-target-url="/" authentication-failure-url="/secure/denied" />
    <logout logout-url="/secure/logout" logout-success-url="/" />
    <expression-handler ref="defaultWebSecurityExpressionHandler" />
</http>

<beans:bean id="authenticationEntryPoint" class="com.ia.security.LoginUrlAuthenticationEntryPoint">
    <beans:constructor-arg name="loginFormUrl" value="/secure/login"/>
</beans:bean>

<beans:bean id="accessDeniedHandler" class="com.ia.security.AccessDeniedHandlerImpl">
    <beans:property name="errorPage" value="/secure/denied"/>
</beans:bean>

我的 AccessDeniedHandlerImpl.java :

public class AccessDeniedHandlerImpl extends org.springframework.security.web.access.AccessDeniedHandlerImpl {
    // SLF4J logger
    private static final Logger logger = LoggerFactory.getLogger(AccessDeniedHandlerImpl.class);

    @Override
    public void handle(HttpServletRequest request, HttpServletResponse response, AccessDeniedException accessDeniedException) throws IOException, ServletException {
        logger.log("AccessDeniedException triggered!");
        super.handle(request, response, accessDeniedException);

    }
}

我的注释方法:

@PreAuthorize("hasAuthority('ROLE_ZZZZ')")
public ModelAndView getUserInfo( @PathVariable long userId ){
    ModelAndView mv = new ModelAndView();
    User u = userService.findUser( userId );
    mv.addObject("user", u);
    return mv;
}

我需要做什么特别的事情来调用我的拒绝访问处理程序吗？

Answer 1

经过几个小时的搜索和跟踪 Spring 代码，我终于发现了发生了什么。我在这里列出它，以防它对其他人有值(value)。
access-denied-handler由 ExceptionTranslationFilter 使用如果是 AccessDeniedException .然而，org.springframework.web.servlet.DispatcherServlet首先尝试处理异常。具体来说，我有一个 org.springframework.web.servlet.handler.SimpleMappingExceptionResolver用 defaultErrorView 定义.因此，SimpleMappingExceptionResolver通过重定向到适当的 View 来消耗异常，因此，没有异常可以冒泡到 ExceptionTranslationFilter .

修复相当简单。配置 SimpleMappingExceptionResolver忽略所有 AccessDeniedException .

<bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
    <property name="defaultErrorView" value="uncaughtException" />
    <property name="excludedExceptions" value="org.springframework.security.access.AccessDeniedException" />

    <property name="exceptionMappings">
        <props>
            <prop key=".DataAccessException">dataAccessFailure</prop>
            <prop key=".NoSuchRequestHandlingMethodException">resourceNotFound</prop>
            <prop key=".TypeMismatchException">resourceNotFound</prop>
            <prop key=".MissingServletRequestParameterException">resourceNotFound</prop>
        </props>
    </property>
</bean>

现在，每当 AccessDeniedException被抛出，解析器忽略它并允许它向上冒泡堆栈到 ExceptionTranslationFilter然后调用 access-denied-handler来处理异常。
