如何将我的Spring4应用程序转给Gmail login这样的aouth2服务器提供商？

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/login/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .oauth2Login()
                .loginPage("/login")
                .defaultSuccessUrl("/home")
                .and()
            .oauth2Client()
                .clientId("your-client-id")
                .clientSecret("your-client-secret")
                .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
                .redirectUriTemplate("your-redirect-uri")
                .authorizationUri("https://accounts.google.com/o/oauth2/auth")
                .tokenUri("https://accounts.google.com/o/oauth2/token")
                .userInfoUri("https://www.googleapis.com/oauth2/v3/userinfo")
                .userNameAttributeName(IdTokenClaimNames.SUB);
    }
}
