- Description copied from interface:
DependencyInjectedFilter
- The
doFilter
method of the Filter is called by the container each time a request/response pair is
passed through the chain due to a client request for a resource at the end of the chain. The FilterChain passed
in to this method allows the Filter to pass on the request and response to the next entity in the chain.
A typical implementation of this method would follow the following pattern:-
1. Examine the request
2. Optionally wrap the request object with a custom implementation to filter content or headers for input
filtering
3. Optionally wrap the response object with a custom implementation to filter content or headers for output
filtering
4. a) Either invoke the next entity in the chain using the FilterChain object (
chain.doFilter()
),
4. b) or not pass on the request/response pair to the next entity in the filter chain to block
the request processing
5. Directly set headers on the response after invocation of the next entity in the filter chain.
- Specified by:
