camel-spring-security: provide reference to the policy when authorization fails
-------------------------------------------------------------------------------

                 Key: CAMEL-2796
                 URL: https://issues.apache.org/activemq/browse/CAMEL-2796
             Project: Apache Camel
          Issue Type: Improvement
    Affects Versions: 2.3.0
            Reporter: Paul Mietz Egli


While it is possible to set up different policies to enforce authorization rules on Camel
routes with the new camel-spring-security plugin, there is currently no way to tell which
policy was being enforced when a org.springframework.security.SpringSecurityException is thrown.
 It would be very helpful to have a reference to the policy ID in the CamelAuthorizationException
or in the headers so we can use it in the onException handlers.

For example, let's say you have two policies:

  <authorizationPolicy id="user" access="ROLE_USER" authenticationManager="authenticationManager"
accessDecisionManager="accessDecisionManager"
    xmlns="http://camel.apache.org/schema/spring-security" />

  <authorizationPolicy id="admin" access="ROLE_ADMIN" authenticationManager="authenticationManager"
accessDecisionManager="accessDecisionManager"
    xmlns="http://camel.apache.org/schema/spring-security" />

You also have two routes which use these policies:

    <camelContext id="myCamelContext" xmlns="http://camel.apache.org/schema/spring">
          <onException useOriginalMessage="true">
            <exception>org.springframework.security.BadCredentialsException</exception>
            <handled><constant>true</constant></handled>
            <to uri="log:auth_error" />
        </onException>
        <route>
            <from uri="direct:adminStart"/>
            <policy ref="admin">
                <to uri="mock:end"/>
            </policy>
        </route>
        <route>
            <from uri="direct:userStart"/>
            <policy ref="admin">
                <to uri="mock:end"/>
            </policy>
        </route>
    </camelContext>

Both of these routes will fail with an AccessDeniedException if the user doesn't have the
proper role, but it would be desirable to handle exceptions for the ROLE_ADMIN failure differently
than the ROLE_USER failure, maybe by using a <choice> element in the <onException>
element.

I know we have the CamelFailureEndpoint header, but this isn't very useful when more than
one route uses the same authorization policy.
