OAuth2.0 Learning (4-11) spring-oauth-server analysis-what kind of authenticationmanager is used by HTTP elements?

1, when loading the configuration file definition, determine which authenticationmanager to use

When the configuration file Security.xml is loaded, a providermanager is created first, and then

If you configured the default Authenauthmanager (HTTP attribute authentication-manager-ref), use the default as the parent of Providermanager

If no default authenauthmanager (HTTP attribute authentication-manager-ref) is configured, Providermanager's parent is null
