问题
I have build a Authentication Service and Webapplication in Spring 5 and Spring boot 2.0.0.M3 and I am trying to port it to Spring boot 2.0.0.M6 now.
I noticed the @EnableOauth2Sso is not available anymore in spring-boot-autoconfigure; I had used this annotation to configure my web application in spring boot 2.0.0.M3 fashion. I have looked into the examples on Spring for configurating the Oauth2 Client using @EnableOAuth2Client but the Configuration objects used in the examples like UserInfoTokenServices also do not seem to exist anymore.
How can I configure my client webapplication for OAuth2 in spring boot versions >= 2.0.0.M6?
回答1:
The existing GitHub issue on spring boot, has been elaborated on, and I was eventually led to the annotation's location in the 2.0.0 release. It has been moved to a project completely new to the 2.0.0 release artifacts.
To resolve this issue and migrate your project, add the artifact org.springframework.security.oauth.boot:spring-security-oauth2-autoconfigure to your dependency management configuration:
<dependency>
<groupId>org.springframework.security.oauth.boot</groupId>
<artifactId>spring-security-oauth2-autoconfigure</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>

This issue is now tracked in GitHub and is available in 2.0.0 SNAPSHOT and targeted for an RC1 release.

Looks like the @EnableOauth2Sso annotation has been moved here:
compile group: 'org.springframework.security.oauth.boot', name: 'spring-security-oauth2-autoconfigure', version: 2.0.0.RELEASE
