Answer 1

You can configure your bean filter and pass as a parameter whatever you need. I know out of Spring context where the filter it is, you cannot get the dependency injection that the auto-scan of spring does. But not 100% sure if there´s a fancy annotation that you can put in your filter to do some magic stuff

   
   YourFilter
       org.springframework.web.filter.DelegatingFilterProxy
    


   YourFilter
       /*
    

and then inject bean in the spring.xml

  
     
        values
