如何使用 Spring Security 保护混合 Spring MVC + Flex 应用程序

我尝试在 Spring 论坛上询问这个问题（http://forum.springsource.org/showthread.php?109948-Problem-configuring-spring-security-3.1-with-hybrid-Spring-MVC-Flex-application http://forum.springsource.org/showthread.php?109948-Problem-configuring-spring-security-3.1-with-hybrid-Spring-MVC-Flex-application）但没有得到回应。

我正在开发一个 Web 应用程序，该应用程序具有使用 Flex 构建的（最终用户）用户界面和使用 Spring MVC 构建的管理用户界面。我正在尝试保护两个接口的安全，并且可以让每个接口单独工作，但不能一起工作。

我正在使用 spring-flex-core 1.5.0 的快照构建以及 Spring Security 3.1RC1 和 Spring 3.1M1

    <security:remember-me/>
    <security:logout logout-url="/logout" logout-success-url="/default.html" />

</security:http>

<bean id="successfulLogInListener" class="uk.co.ecube.web.security.SuccessfulLogInListener"/>
<bean id="failedLogInListener" class="uk.co.ecube.web.security.FailedLogInListener"/>


<security:authentication-manager>
    <security:authentication-provider user-service-ref='userService'/>
</security:authentication-manager>
</beans>

如果我只包含第一个 http 标签而不包含模式属性，那么 Flex UI 似乎可以使用 Spring 安全性成功进行身份验证。但是如果我包括所有<http>标签，然后我会收到两个错误之一，具体取决于我是否使用

<security:http  entry-point-ref="entryPoint">
    <security:anonymous enabled="false"/>
</security:http>

这使

SEVERE: Exception sending context initialized event to listener instance of class  org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.parsing.BeanDefinitionParsingException:  Configuration problem: The filter chain map already contains this request matcher [Root  bean: class [org.springframework.security.web.util.AnyRequestMatcher]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null]. If you are using multiple <http> namespace elements, you must use a 'pattern' attribute to define the request patterns to which they apply.

or

   <security:http pattern="/messagebroker/**" entry-point-ref="entryPoint">
    <security:anonymous enabled="false"/>
</security:http>

这导致

SEVERE: Servlet /apollo threw load() exception
org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type   [org.springframework.security.web.authentication.session.SessionAuthenticationStrategy] is defined: expected single matching bean but found 2: [org.springframework.security.web.authentication.session.SessionFixationProtectionStrategy#0, org.springframework.security.web.authentication.session.SessionFixationProtectionStrategy#1]
at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:796)

我显然遗漏了一些东西，但是虽然 Spring Flex 文档描述了如何在 servlet 级别配置混合 MVC+Flex 应用程序，但它似乎只从纯 Flex 应用程序的角度考虑安全性。

谁能建议我做错了什么？

我之前在处理同一问题时使用过的一件事是有 2 个单独的 DispatcherServlet：

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

<servlet>
    <servlet-name>flex</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>flex</servlet-name>
    <url-pattern>/messagebroker/*</url-pattern>
</servlet-mapping>

<servlet>
    <servlet-name>spring-mvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>spring-mvc</servlet-name>
    <url-pattern>/spring/*</url-pattern>
</servlet-mapping>

您还需要通过将 MVC 路径修改为来更新安全配置/spring/...

我几乎可以肯定，当您使用 SpringS 而不是 BlazeRS 时，这不是最好的解决方案。一定有更优化的方法！

您还可以尝试删除：

<security:http pattern="/messagebroker/**" entry-point-ref="entryPoint">
    <security:anonymous enabled="false"/>
</security:http>

而不是尝试使用这个：

<flex:message-broker mapping-order="1">
    <flex:mapping pattern="/messagebroker/*"/>
    <flex:message-service default-channels="amf, polling-amf, longpolling-amf" />
    <flex:secured>
       <flex:secured-channel channel="amf" access="ROLE_SOME_ROLE" />
   </flex:secured>
</flex:message-broker>

请记住，身份验证应通过 Flex 客户端上的通道集完成！
