Discord4j Bot Run of java main: работает нормально < /li>
Discord4j Bot Run в рамках A Quarkus Main: не разрешает DNS для Discord.com < /li>

Что делает Quarkus, который предотвратит < /p>
the Контекст < /h2>
Я пытаюсь заставить Discord4j работать в Quarkus, но я сталкиваюсь с некоторыми ошибками. , и это работает нормально, если я бегу из основного метода Java. Ну, может быть, не так много, но вдруг реактор Нетти больше не может разрешить домен Discord.com (стек доступен ниже). < /P>
Код Quarkus и основной метод вызовите тот же код Полем Единственное отличие состоит в том, что токен Discord поступает из @ConfigMapping вместо жесткого кодирования, но значение правильно вводится. < /P>
вещи, которые я попробовал < /h2>
< ul>
Я попытался принудить реагируйте, как предложено на другом, очевидно, связанный с этим вопросом из года назад, но он ничего не решил. < /li>
Я также дал Quarkus Discord4j быстро пытается, но, похоже, у него есть те же симптомы -> это предполагает, что это не всегда было проблемой, возможно, что -то, связанное с эволюцией Quarkus (POM Project предполагает, что это было последнее тестирование с Quarkus 3.7, вероятно, год Я назад). Netty?) Конфигурация, но я не могу найти подробную информацию об этом, или как это приведет к этой ошибке. Проблема? >
