org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter
public class UsernamePasswordAuthenticationFilter
Processes an authentication form. Called AuthenticationProcessingFilter in previous versions of the framework.
Login forms must present two parameters to this filter: a username and
password. The default parameter names to use are contained in the
static fields SPRING_SECURITY_FORM_USERNAME_KEY
and SPRING_SECURITY_FORM_PASSWORD_KEY
.
The parameter names can also be changed by setting the usernameParameter and passwordParameter
properties.
This filter by default responds to the URL /j_spring_security_check.

public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException
AbstractAuthenticationProcessingFilter
The implementation should do one of the following:
attemptAuthentication
in class AbstractAuthenticationProcessingFilter
request
- from which to extract parameters and perform the authenticationresponse
- the response, which may be needed if the implementation has to do a redirect as part of a
multi-stage authentication process (such as OpenID).
AuthenticationException
- if authentication fails.protected String obtainPassword(HttpServletRequest request)
This might be used for example if a postcode/zipcode was required in addition to the
password. A delimiter such as a pipe (|) should be used to separate the password and extended value(s). The
AuthenticationDao
will need to generate the expected password in a corresponding manner.
