Spring Security and OSGi

Question

I am trying to create a simple example using Spring Security 3.1.3 on Virgo 3.6.0.M03. The example consists of 3 bundles:

• security bundle configuring and publishing an AuthenticationManager

  <security:authentication-manager id="authenticationManager">
     <security:authentication-provider>
        <security:user-service>
           <security:user name="Rigas" password="password" authorities="ROLE_MEMBER"/>
        </security:user-service>
     </security:authentication-provider>
  </security:authentication-manager>
  <service id="authenticationManagerOsgi" ref="authenticationManager" interface="org.springframework.security.authentication.AuthenticationManager"/>
  

• helloSecurity bundle publishing a secured helloWorld method. It references the AuthenticationManager and injects it in global-method-security.

  <security:global-method-security secured-annotations="enabled" authentication-manager-ref="authenticationManager"/>
  <reference id="authenticationManager" availability="mandatory" interface="org.springframework.security.authentication.AuthenticationManager"/>
  <service id="helloSpringSecurityOsgi" ref="helloSpringSecurity" interface="net.ansible.examples.hellospringsecurity.HelloSpringSecurity" />
  

• helloSecurityConsumer bundle referencing the helloSecurity IF and calling the secured helloWorld method.

  <reference id="helloSpringSecurity" availability="mandatory" interface="net.ansible.examples.hellospringsecurity.HelloSpringSecurity"/>
  

Bundle statup and wiring work properly, but once helloSecurityConsumer calls the secured method the following exception is thrown:

Failed to call secure method org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'authenticationManager' must be of type [org.springframework.security.authentication.ProviderManager], but was actually of type [$Proxy94]

GlobalMethodSecurityBeanDefinitionParser attempts to use the referenced AuthenticationManager and has a problem converting the Proxy around the OSGi refeternce to a ProviderManager. Debugging shows the Proxy (a jdkDynamicAopProxy) is indeed a proxy around the ProviderManager class and has all the relevant interfaces. Is there a working configuration to achieve what I am trying to do?

Answer 1

This looks like a bug to me. Line 386 of the file GlobalMethodSecurityBeanDefinitionParser.java that raises the error is

delegate = beanFactory.getBean(authMgrBean, ProviderManager.class);

It asks the bean factory for an bean with the concrete implementation ProviderManager, but it should only request a bean with the interface AuthenticationManager like:

delegate = beanFactory.getBean(authMgrBean, AuthenticationManager.class);

You may want to raise a ticket in Spring Security's Jira.

BTW: We are also exporting the authenticationManager as an OSGI service and consume it in other bundles, which works really well.
