Class SecurityAwareConfigurer

java.lang.Object
  org.springframework.richclient.security.SecurityAwareConfigurer

All Implemented Interfaces:

EventListener, BeanPostProcessor, ApplicationContextAware, ApplicationListener

public class SecurityAwareConfigurer
extends Object
implements ApplicationListener, ApplicationContextAware, BeanPostProcessor

This class performs two main functions:

1. It is a bean post-processor that will set the current authentication token on any newly created beans that implement AuthenticationAware.
2. It listens for application ClientSecurityEvents and updates all the beans in the context that implement either AuthenticationAware or LoginAware according to the event received.

In order for all this to take place, a singleton, non-lazy instance of this class must be defined in the Spring ApplicationContext. This would be done like this:

              <bean id="securityAwareConfigurer"
                   class="org.springframework.richclient.security.SecurityAwareConfigurer"
                   lazy-init="false"/>
