Annotation-based API proposal 1

[OndroMih]

Annotation-based consumer and client API - proposal 1 for jakartaee/messaging#249 and jakartaee/messaging#243

This proposal is based on the proposals in the https://github.com/tomitribe/jms-proposals repository.

The gist of the proposal:

• The consumer part is exemplified in the NotificationsListener and BuildAndNotify classes, which are annotated by @MessageConsumer and their method annotated by @TopicListener or QueueListener annotations
• The client part is exemplified in the BuildAndNotify class, which uses the MessagingClientBuilder builder to build an implementation of an interface (NotificationsClient). The NotificationsClient is a client interface which defines that how the client object should be built. Each method and its parameters are annotated to specify the target queue or topic and how to convert arguments to a message.
