Spring Security Tonr2 remove application login - spring-security

Question

I was successfully able to add google as another authenticator in tonr2 example application. But what I'm stuck with is, removing the application's login screen and make use of google as mode of authentication into the application.
Also, each time I click on Google Info, I'm always taken to the "Accept"/"No Thanks" Page instead of remembering my approval already (I've logged in the same google account at all times)
Here is my modified spring-servlet.xml
<sec:http access-denied-page="/login.jsp?authorization_error=true" >
<sec:custom-filter ref="oauth2ClientFilter" after="EXCEPTION_TRANSLATION_FILTER" />
<sec:intercept-url pattern="/google/**" access="IS_AUTHENTICATED_ANONYMOUSLY" />
<sec:intercept-url pattern="/**" access="IS_AUTHENTICATED_ANONYMOUSLY" />
<sec:form-login authentication-failure-url="/login.jsp?authentication_error=true"
default-target-url="/index.jsp" login-page="/login.jsp"
login-processing-url="/login.do" />
<sec:logout logout-success-url="/index.jsp" logout-url="/logout.do" />
</sec:http>
<sec:authentication-manager >
<sec:authentication-provider>
<sec:user-service>
<sec:user name="marissa" password="wombat" authorities="ROLE_USER" />
<sec:user name="sam" password="kangaroo" authorities="ROLE_USER" />
</sec:user-service>
</sec:authentication-provider>
</sec:authentication-manager>
