java.lang.Objectorg.springframework.web.filter.CompositeFilter
public class CompositeFilter
A generic composite servlet Filter
that just delegates its behaviour 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.
