Spring - MVC

DelegatingFilterProxy

* <p>{@code web.xml} will usually contain a {@code DelegatingFilterProxy} definition,
 * with the specified {@code filter-name} corresponding to a bean name in
 * Spring's root application context. All calls to the filter proxy will then
 * be delegated to that bean in the Spring context, which is required to implement
 * the standard Servlet 2.3 Filter interface.
