I cannot find a complete example anywhere of a Spring Security Web App with Open Id registration similar to stackoverflows.
I would say I\'m pretty tec
I know this is not really helpful in answering your Question but I am currently building a Grails based web application and initailly started using Spring Security but also found it difficult to setup.
I then changed to Apache Shiro and it is much simpler to implement. But it doesn't have support for openid out of the box, but the nimble grails plugin does so you may be able to use that as an example to write your own.
Yes,
There is a war to download on http://repo1.maven.org/maven2/org/springframework/security/spring-security-samples-openid/3.0.1.RELEASE/
Maybe it can help you.
Yes, In spring application, user can authenticate into your application with open ID provider.
1) Here is the sample example of spring open ID login application.
2) Here is the sample example of spring security social login application and blog here.
Have you looked at the latest version of the sample code (for the 3.1 release)?
It has several improvements to make it simpler to use Google and Yahoo authentication together (with different attribute exchange configurations simultaneously), uses a similar login dialog to stack overflow and performs simple registration in the case of users who have not previously accessed the app.
See this issue https://jira.springsource.org/browse/SEC-1431 (and the linked one) for more information.
It's not exactly OpenID, it uses Facebook Connect, but checkout Spring's GreenHouse. That's great code written by the guys from Spring you can use to jumpstart your app.
