Spring Cloud Gateway Server MVC - Можем ли мы использовать Spring MVC с Spring Cloud Gateway? ⇐ JAVA

[Anonymous]

Какова цель Spring Cloud Gateway Server MVC? Можно ли его использовать вместо реактивного Gateway Spring Cloud Gateway? Если так, может ли кто-нибудь дать пример? Понять. < /p>
Вот моя конфигурация. < /p>

У меня есть еще одна служба Spring Boot, работающая на 8081. Мне нужно перенаправить его на эту службу, но она не работает. Может ли кто -нибудь объяснить мне, что должно быть изменение? Спасибо за помощь. Я внес изменения в предложенное, но я получаю ошибку. Я также удалил Spring Security, чтобы проверить, правильно ли работает маршрут. < /P>
