extended OAuth2RestTemplate can not be wired - spring

Question

I need to extend the provided OAuth2RestTemplate implementation because of an additional required behavior, which is not part of the OAuth spec.
Unfortunately, I'm not able to get my extended class wired to other spring provided classes.
I defined my own bean factory methods but there are other bean factories (e.g. OAuth2RestOperationsConfiguration) wich use #Primary for such methods.
I also tried something like this:
#EnableAutoConfiguration(
exclude = {
OAuth2RestOperationsConfiguration.class, ResourceServerTokenServicesConfiguration.class, ResourceServerTokenServicesConfiguration.class} )
But the application start always fails with errors like this:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springSecurityFilterChain' defined in class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.servlet.Filter]: Factory method 'springSecurityFilterChain' threw exception; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [org.springframework.security.oauth2.client.OAuth2RestOperations] is defined: more than one 'primary' bean found among candidates: [oauth2RestTemplate, customOAuth2RestTemplateX, userInfoRestTemplate, customOAuth2RestTemplateY]

How can I get my extended class wired to other spring provided classes?
I need it here for example:
SsoSecurityConfigurer#oauth2SsoFilter
private OAuth2ClientAuthenticationProcessingFilter oauth2SsoFilter(
OAuth2SsoProperties sso) {
OAuth2RestOperations restTemplate = this.beanFactory
.getBean(OAuth2RestOperations.class);
[...]
}

Answer 1

We actually fixed that in Spring Boot 1.4.0.M3. We no longer create that bean and you have to create it yourself. It is currently hard-coded to #Primary in the auto-configuration which was a mistake on our end (and the reason why you can't override it).
I am afraid you'll have to upgrade to Spring Boot 1.4.0.M3. You could make it work in 1.3 by copy/pasting the configuration that you want to use from OAuth2RestOperationsConfiguration and exclude that auto-configuration.
