问题 While going through the processing of a request in JAX-RS, what I studied is that the flow of the whole process is as below; I know that there are different components , which serve the purpose of pluggability, like we can have filters and can plug them to whatever resource methods we want, same is the case with interceptors(and I know that they are triggered around MessageBodyWriters and MessageBodyReaders). But I am confused about each of the component and the piece of information which
