使用 Spring Boot 的 OAuth2 SSO 没有授权屏幕

Question

I have resource, authorization and _ui applications written using Spring Boot 1.5.3, OAuth2 and MongoDB.

The resources are going to be accessed from mobile apps as well as a couple of web applications (one for regular users and the other one for admins). The apps are quite similar to the samples from the guides by Dave Syer. What different is that the users are stored in the database and the clients are stored in an xml file located in the resources folder of the authorization server.

I am struggling with the logon experience for the web users. Following the guides for the JWT based OAuth app, after the login page, the user is redirected to the authorization screen, which is not the desired behavior. Ie, I don't want my authorization server to ask if the user trusts my web application to access its resources . Instead, I want users redirected to the ui pages right after login, as one would expect.

I found this project on GitHub (very similar to the apps from the guide) which behaves exactly as I want, but once I start customizing it by adding my authentication and authorization implementation, it reverts back to using the authorization screen. Apparently, I am missing something, but I was not able to figure out what exactly.

Answer 1

From http://www.springframework.org/schema/security/spring-security-oauth2.xsd Element client-details-service > complexType client > attribute autoaprove

Scopes or scope patterns that are autoapproved (comma-separated), or just "true" to autoapprove all.

Just add the autoapprove="true" attribute to your trusted-app in client-details.xml . That way the authserver will not request user's confirmation to access the resources.

Here is an example of how to implement this behaviour directly in your Java configuration.

Answer 2

Additionally, if your clients are provided by a database, actually DataSource , then the AUTOAPPROVE column of related client should be set to 'true' in the table OAUTH_CLIENT_DETAILS .
