ClassCastException при включении поддержки HTTP / 2 в Spring Cloud API Gateway в 2.1.9.

См. Я могу включить поддержку HTTP / 2 в пользовательском интерфейсе на сервере пристани с JDK8, исключив стартер tomcat и добавив причал, запущенный в весеннюю веб-конфигурацию, а также добавив пристань-alpn-Sovrypt-server, зависимость http2-server.

Но на стороне Spring Cloud API Gateway, которая использует сервер Netty, Я перепробовал все шаги и не смог понять, как включить HTTP / 2 здесь, в Spring Cloud API Gateway, я добавил netty -tcnative-boringssl-static как зависимость, и теперь я получаю эту ошибку

Вы пробовали исправленную версию Reactor Netty ›0.8.12.RELEASE, потому что в приведенной выше трассировке стека вы все еще используете версию, в которой существует проблема?   -  person Violeta Georgieva    schedule 25.11.2020

Я решил эту проблему, обновив загрузочную версию до 2.2.5.RELEASE и облачную версию до Hoxton.SR3.
