Subject: Disable __TypeId__ header for AAI event publishing
X-Git-Tag: 1.15.3~2
X-Git-Url: https://gerrit.onap.org/r/gitweb?a=commitdiff_plain;h=19edf73380685134aa75e2c5e2ad78d275d98118;p=aai%2Faai-common.git

Disable __TypeId__ header for AAI event publishing

- with the refactorings in AAI-3931 and AAI-4014 message producing was changed
  to serialize <String,NotificationEvent> instead of <String,String> to be more expressive
- when doing so, spring will add a __TypeId__ header to the message to inform consumers
  about the type of the message
- spring consumers will validate this annotation and will
    - throw an exception when the package (org.onap.aai.[...].NotificationEvent) is not among the trusted packages
    - throw an exception if the class is not on the classpath and the app thus does not know how to deserialize it
- since this is a breaking change for the consumers and it would just cause implementation effort, the header is removed to restore the old behaviour
