第8题:
Your filter class must implement an init method and a destroy method.
Your filter class must also implement javax.servlet.FilterChain.
When your filter chains to the next filter, it should pass the same arguments it received in its doFiltermethod.
The method that your filter invokes on the object it received that implements javax.servlet.FilterChaincan invoke either another filter or a servlet.
Your filter class must implement a doFilter method that takes, among other things, anHTTPServletRequest object and an HTTPServletResponse object.
第9题:
The init method on a filter is called the first time a servlet mapped to that filter is invoked.
A filter defined for a servlet must always forward control to the next resource in the filter chain.
Filters associated with a named servlet are applied in the order they appear in the web application deployment descriptor file.
If the init method on a filter throws an UnavailableException, then the container will make no further attempt to execute it.
