Boot, OAuth2, Zuul Proxy and Versions - spring

Question

So, i've added in Zuul and to get the proxy working realised i needs to add in 'spring-cloud-security' which i did:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-security</artifactId>
<version>1.1.0.M2</version>
</dependency>
The trouble is that as soon as i do this i get this exception
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'loadBalancedOauth2RestTemplate' defined in class path resource [org/springframework/cloud/security/oauth2/client/ OAuth2LoadBalancerClientAutoConfiguration$LoadBalancedOauth2RestTemplateConfig.class]: Unsatisfied dependency expressed through constructor argument with index 2 of typ[org.springframework.security.oauth2.client.resource.OAuth2ProtectedResourceDetails]: : No qualifying bean of type [org.springframework.security.oauth2.client.resource.OAuth2ProtectedResourceDetails] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.security.oauth2.client.resource.OAuth2ProtectedResourceDetails] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}
at org.springframework.beans.factory.support.ConstructorResolver.createArgumentArray(ConstructorResolver.java:749) ~[spring-beans-4.2.4.RELEASE.jar:4.2.4.RELEASE]
if i do make a bean i get this exception (i'm specifying the resource server info outside of props/yml):
Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [org.springframework.security.oauth2.client.OAuth2RestTemplate] is defined: expected single matching bean but found 2: userInfoRestTemplate,loadBalancedOauth2RestTemplate
at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:1126) ~[spring-beans-4.2.4.RELEASE.jar:4.2.4.RELEASE]
I've been through this previous post:
https://github.com/spring-cloud/spring-cloud-security/issues/73
I'm using Spring Boot 1.3.3.RELEASE. I've tried (form the above posting) adding in to dep management:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-parent</artifactId>
<version>Brixton.M3</version>
<type>pom</type>
<scope>import</scope>
</dependency>
but to no avail.
I expect this is a 'versions' issue; what is the most recent set of libs & versions to use? I've been through the 'oauth2-vanilla-ui' sample in the AngularJS/Security tutorial. Is it because i'm not using props in the resource file?

Answer 1

Ok, so i managed to figure it out. So i upped the version of 'spring-cloud-security' to '1.1.0.M4' as I noticed some of the autoconf had changed. Also, i left my 'OAuth2ProtectedResourceDetails' as a bean and added an 'OAuth2RestTemplate' bean but, crucially, marked it as primary:
#Primary
#Bean(name = "platformClientRestTemplate")
public OAuth2RestTemplate clientRestTemplate() {
return new OAuth2RestTemplate(platformOAuth2ProtectedResourceDetails(), oauth2ClientContext);
}
this means the problem of multiple RestTemplates goes away (and ensures the rest template i want gets used).
This means i'm using (for anyone with version issues):
Boot 1.3.3.RELEASE
spring-cloud-security 1.1.0.M4
spring-cloud-starter-zuul 1.1.0.M3
