public class CompositeFilter
A generic composite servlet Filter that just delegates its behavior
to a chain (list) of user-supplied filters, achieving the functionality of a
FilterChain, but conveniently using only Filter instances.
This is useful for filters that require dependency injection, and can
therefore be set up in a Spring application context. Typically, this
composite would be used in conjunction with DelegatingFilterProxy,
so that it can be declared in Spring but applied to a servlet context.
