How to implement a custom filter in Spring Security?

Comment

You can implement a custom filter in Spring security by implementing the org.springframework.web.filter.GenericFilterBean class. 
The GenericFilterBean is a simple javax.servlet.Filter implementation which is Spring aware. 
You can override doFilter(ServletRequest req, ServletResponse res, FilterChain chain) to implement your own logic.
