Spring Security Spring Security configuration

I have a problem about Spring Security。it may not a bug。but i can‘t find answer。

Spring Security provides a variety of options for performing authentication. These follow a simple contract – an Authentication request is processed by an AuthenticationProvider and a fully authenticated object with full credentials is returned.

My configuration it may look like this： in ProviderManager class： the source code is like this： It does circular processing for all AuthenticationProvider。 Now i want： if(A) use daoAuthenticationProvider if(B) use daoAuthenticationProvider2 what should I do？ My configuration is spring-security2.0.3.I want an idea。 should I rewrite one custom ProviderManager？
