Method Summary

protected org.apache.shiro.authc.AuthenticationToken	createToken(javax.servlet.ServletRequest request, javax.servlet.ServletResponse response) The token created for this authentication is an OAuthToken containing the OAuth credential received after authentication at the OAuth provider.
protected boolean	isAccessAllowed(javax.servlet.ServletRequest request, javax.servlet.ServletResponse response, Object mappedValue) Returns false to always force authentication (user is never considered authenticated by this filter).
protected boolean	onAccessDenied(javax.servlet.ServletRequest request, javax.servlet.ServletResponse response) Execute login by creating token and logging subject with this token.
protected boolean	onLoginFailure(org.apache.shiro.authc.AuthenticationToken token, org.apache.shiro.authc.AuthenticationException ae, javax.servlet.ServletRequest request, javax.servlet.ServletResponse response) If login has failed, redirect user to the error page except if the user is already authenticated, in which case redirect to the default success url.

Method Detail

createToken

protected org.apache.shiro.authc.AuthenticationToken createToken(javax.servlet.ServletRequest request,

Parameters:

request - the incoming request

response - the outgoing response

Throws:

Exception - if there is an error processing the request.

onAccessDenied

protected boolean onAccessDenied(javax.servlet.ServletRequest request,
                                 javax.servlet.ServletResponse response)
                          throws Exception

Execute login by creating token and logging subject with this token.

Specified by:

onAccessDenied in class org.apache.shiro.web.filter.AccessControlFilter

Parameters:

request - the incoming request

response - the outgoing response

Throws:

Exception - if there is an error processing the request.

isAccessAllowed

protected boolean isAccessAllowed(javax.servlet.ServletRequest request,
                                  javax.servlet.ServletResponse response,
                                  Object mappedValue)

Parameters:

request - the incoming request

response - the outgoing response

mappedValue - the filter-specific config value mapped to this filter in the URL rules mappings.

Returns:

false

onLoginSuccess

protected boolean onLoginSuccess(org.apache.shiro.authc.AuthenticationToken token,
                                 org.apache.shiro.subject.Subject subject,
                                 javax.servlet.ServletRequest request,
                                 javax.servlet.ServletResponse response)
                          throws Exception

If login has been successful, redirect user to the original protected url.

Overrides:

onLoginSuccess in class org.apache.shiro.web.filter.authc.AuthenticatingFilter

Parameters:

token - the token representing the current authentication

subject - the current authenticated subjet

request - the incoming request

                                 javax.servlet.ServletResponse response)

If login has failed, redirect user to the error page except if the user is already authenticated, in which case redirect to the default success url.

Overrides:

onLoginFailure in class org.apache.shiro.web.filter.authc.AuthenticatingFilter

Parameters:
