public class DigestAuthenticationFilter extends org.springframework.web.filter.GenericFilterBean implements org.springframework.context.MessageSourceAware
Processes a HTTP request's Digest authorization headers, putting the result into theSecurityContextHolder
.For a detailed background on what this filter is designed to process, refer to RFC 2617 (which superseded RFC 2069, although this filter support clients that implement either RFC 2617 or RFC 2069).
This filter can be used to provide Digest authentication services to both remoting protocol clients (such as Hessian and SOAP) as well as standard user agents (such as Internet Explorer and FireFox).
This Digest implementation has been designed to avoid needing to store session state between invocations. All session management information is stored in the "nonce" that is sent to the client by the
DigestAuthenticationEntryPoint
.If authentication is successful, the resulting
Authentication
object will be placed into theSecurityContextHolder
.If authentication fails, an
AuthenticationEntryPoint
implementation is called. This must always beDigestAuthenticationEntryPoint
, which will prompt the user to authenticate again via Digest authentication.Note there are limitations to Digest authentication, although it is a more comprehensive and secure solution than Basic authentication. Please see RFC 2617 section 4 for a full discussion on the advantages of Digest authentication over Basic authentication, including commentary on the limitations that it still imposes.

setCreateAuthenticatedToken
public void setCreateAuthenticatedToken(boolean createAuthenticatedToken)
If you set this property, the Authentication object, which is created after the successful digest authentication will be marked as authenticated and filled with the authorities loaded by the UserDetailsService. It therefore will not be re-authenticated by your AuthenticationProvider. This means, that only the password of the user is checked, but not the flags like isEnabled() or isAccountNonExpired(). You will save some time by enabling this flag, as otherwise your UserDetailsService will be called twice. A more secure option would be to introduce a cache around your UserDetailsService, but if you don't use these flags, you can also safely enable this option.- Parameters:
createAuthenticatedToken
- default is false
-
setSecurityContextRepository
public void setSecurityContextRepository(SecurityContextRepository securityContextRepository)
Sets theSecurityContextRepository
to save theSecurityContext
on authentication success. The default action is not to save theSecurityContext
.- Parameters:
securityContextRepository
- theSecurityContextRepository
to use. Cannot be null.
-
setSecurityContextHolderStrategy
public void setSecurityContextHolderStrategy(SecurityContextHolderStrategy securityContextHolderStrategy)
Sets theSecurityContextHolderStrategy
to use. The default action is to use theSecurityContextHolderStrategy
stored inSecurityContextHolder
