Can configure @EnablePublisher(proxyTargetClass=true)

Enhancement

Problem: As discussed in https://stackoverflow.com/questions/54150939/spring-cloud-stream-and-publisher-annotation-compatiblity/54151130, services using @Publisher annotation can't be injected using @Autowire

Possible solution: using an annotation like @EnablePublisher(proxyTargetClass=true). Other proxy implementations of Spring like @Cacheable or @Async use this flag.

Until the annotation is fixed, I added a work around here.

Another issue is like this: https://stackoverflow.com/questions/54207305/spring-cloud-stream-streamlistener-processing-messages-twice.

To reconsider the PublisherAnnotationBeanPostProcessor bean as really a singleton and don't depend on particular name.
However at the same time end-user may declare several of them, so maybe it is better consider do not apply the PublisherAnnotationAdvisor to the same bean more than once.
