Set property of FilterSecurityInterceptor without creating custom filter

问题

If I understand correctly, when I configured Spring Security an instance of FilterSecurityInterceptor was created automatically. I would like to set the alwaysReauthenticate property to true, but I don't want to create my own FilterSecurityInterceptor or configure my own custom filter chain. Is there a way to do this?

Update: May 01, 2012 Based on the comment below I came up with this code, which is working just as desired:

public class ForceAuthCheckinator implements BeanPostProcessor {
    @Override
    public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
        return bean;
    }

    @Override
    public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
        if (beanName.contains("FilterSecurityInterceptor")) {
            ((FilterSecurityInterceptor bean).setAlwaysReauthenticate(true);
        }
        return bean;
    }
}

Then in my application context file I added this single line, which activated the class and wired it into place:

<bean class="com.mydomain.ForceAuthCheckinator"/>

Thanks for the help.

A typical solution for this kind of problems is to create a BeanPostProcessor that will intercept initialization of FilterSecurityInterceptor bean and apply necessary customizations to it.
