Method Detail

• init

  public void init(FilterConfig config)
            throws ServletException

  Initialize this servlet.

  Specified by:

  init in interface Filter

  Parameters:

  config - The configuration information associated with the filter instance being initialised

  Throws:

  ServletException - if an error occurs

• doFilter

  public void doFilter(ServletRequest request,
              ServletResponse response,
              FilterChain chain)
                throws IOException,
                       ServletException

  Description copied from interface: Filter
  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:

  doFilter in interface Filter

  Parameters:

  request - The request to process

  response - The response associated with the request

  chain - Provides access to the next filter in the chain for this filter to pass the request and response to for further processing

  Throws:

  IOException - if an I/O error occurs during this filter's processing of the request

  ServletException - if the processing fails for any other reason

• destroy

  public void destroy()

  Description copied from interface: Filter
  Called by the web container to indicate to a filter that it is being taken out of service. This method is only called once all threads within the filter's doFilter method have exited or after a timeout period has passed. After the web container calls this method, it will not call the doFilter method again on this instance of the filter.
  
  This method gives the filter an opportunity to clean up any resources that are being held (for example, memory, file handles, threads) and make sure that any persistent state is synchronized with the filter's current state in memory.

  Specified by:

  destroy in interface Filter
