Отслеживание распространения идентификатора в Spring Boot 3 с помощью облачных потоков Spring и WebFlux
Я попытался использовать весенний облачный поток с связующим кафкой. Но когда я вызываю WebClient в цепочке, идентификатор трассировки теряется.
Мой поток'external service' -> 'functionStream-in' -> 'http call' -> functionStream-out' -> 'testStream-in' -> 'testStream-out' -> 'external service'
Но после http-вызова (или нет?) идентификатор трассировки не распространяется, и я не понимаю, почему. Если убрать http вызов, то все ок.
я пытался добавитьHooks.enableAutomaticContextPropagation();, но это не помогло. я пытался добавитьContextSnapshot.setThreadLocalsFromвокруг http вызова - то же самое.
Как я могу это решить?
