duplicate bean

@huangyangcong could you please share your configuration? It looks like you may be using spring-security-oauth2 as well as spring-security-oauth2-client.

springboot version 2.1.0.M4

@huangyangcong, this was addressed in #39 which it appears that spring-cloud-starter-oauth2 may not pick up until their 2.1.0.RC1 release.

In the meantime, please use the following property in your application.yml:

spring.main.allow-bean-definition-overriding: true

Let me know if that works for you.

The demo app you uploaded also revealed a related issue, which is why I'm not just yet recommending that you simply override the spring-security-oauth2-autoconfigure dependency in your pom just yet.

Thank you for your reply to solve my problem.

@huangyangcong also, OOC, I noticed that you are using @EnableOAuth2Client also with client credentials, which isn't necessary. From the @EnableOAuth2Client java doc:

Enable configuration for an OAuth2 client in a web application that uses Spring Security and wants to use the Authorization Code Grant from one or more OAuth2 Authorization servers.

Is there a reason that you are using @EnableOAuth2Client and client credentials together? (Wondering if there is something in the docs that is suggesting this)?

I Just learning springcloud and oauth2
http://projects.spring.io/spring-security-oauth/docs/oauth2.html
Different grant types have different concrete implementations of OAuth2ProtectedResourceDetails (e.g. ClientCredentialsResource for "client_credentials" grant type). For grant types that require user authorization there is a further property:
I want to change the authorization code to client credentials。

谢谢您的提醒
Thank you for reminding me
