Is your feature request related to a problem? Please describe.
Users would like to assign certain interceptors/customizers to certain namespaces in a multi namespace setup. Currently users can do this but they must specify it by prefixing the bean name with the appropriate namespace.
Describe the solution you'd like
A Java annotation or interface may be more idiomatic in Springboot
Describe alternatives you've considered
Keep the customization by bean name prefix.
