Yes, you can use @RequestInterceptor and @ResponseInterceptor to the class
level so that it will apply to every resource invocation in the service.
Example:
@Path("/stockquote")
@RequestInterceptor(
HTTPRequestLogger.class)
@ResponseInterceptor({HTTPResponseLogger.class,
LogTextResponseInterceptor.class})
public class StockQuoteService {
// Your resource methods here
}
Furthermore, if you want to apply the interceptors to all the services
in a micro-service in OSGi mode please refer [1] and for non-OSGi mode
please refer [2] and [3].

In this case the ABCRequestInterceptor will be the interceptor which gets
executed. Please note that the other interceptors which is extended from
this class do not get executed (The class you mention in the annotation is
taken exactly as it is)
