+ architecture I f you are asking about the dynamic interceptors similar to the dynamic binding of filters in JAX-RS spec [1], MSF4J currently do not support dynamic binding of interceptors.
[1] https://access.redhat.com/documentation/en-us/red_hat_ jboss_fuse/6.3/html/apache_cxf_development_guide/ jaxrs20filters#JAXRS20Filters-DynamicBinding Yes, We need a way to bind Interceptors which are coming from a configuration. But that also has to be per service , not the global. Because For instance, We have the publisher REST API implemented as a micro service. We need to secure this service using interceptors. Further, we are planning to have one interceptor per authentication type(BasicAuth, OAuth2, etc.). Now, if someone need to add a custom authenticator, it should be possible to write a custom authentication interceptor and plug it into the Microservice. Can this be supported?
