Description copied from class: BypassableDelegatingFilterProxy

Bypasses execution of the filter if no WebApplicationContext is available, delegating directly to the filter chain, or performs normal filtering if a context is available.

Once a WebApplicationContext is available once, this filter will never bypass again (even if, for some reason, the context later disappears).

Specified by:

doFilter in interface javax.servlet.Filter

Overrides:

doFilter in class BypassableDelegatingFilterProxy

Parameters:

request - the servlet request to filter

response - the servlet response

filterChain - the filter chain

Throws:

javax.servlet.ServletException - May be thrown by the base class or the chain; never thrown locally.

IOException - May be thrown by the base class or the chain; never thrown locally.
