org.acegisecurity.captcha.CaptchaValidationProcessingFilter
- All Implemented Interfaces:
- javax.servlet.Filter, org.springframework.beans.factory.InitializingBean
- public class CaptchaValidationProcessingFilter
- extends java.lang.Object
- implements org.springframework.beans.factory.InitializingBean, javax.servlet.Filter
Filter for web integration of the CaptchaServiceProxy.
It basically intercept calls containing the specific validation parameter,
use the CaptchaServiceProxy to validate the request, and update the
CaptchaSecurityContext if the request passed the validation.
This Filter should be placed after the ContextIntegration filter and before
the CaptchaChannelProcessorTemplate filter in the filter stack in
order to update the CaptchaSecurityContext before the humanity
verification routine occurs.
This filter should only be used in conjunction with the CaptchaSecurityContext

- Description copied from interface:
org.springframework.beans.factory.InitializingBean
- Invoked by a BeanFactory after it has set all bean properties supplied
(and satisfied BeanFactoryAware and ApplicationContextAware).
This method allows the bean instance to perform initialization only
possible when all bean properties have been set and to throw an
exception in the event of misconfiguration.

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

- Does nothing. We use IoC container lifecycle services instead.

doFilter
public void doFilter(javax.servlet.ServletRequest request,
javax.servlet.ServletResponse response,
javax.servlet.FilterChain chain)
throws java.io.IOException,
javax.servlet.ServletException
- Description copied from interface:
javax.servlet.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.
