Клиент Spring Cloud Eureka не запускается из-за джерси

#spring-boot #microservices #spring-cloud #netflix-eureka

#пружинный ботинок #микросервисы #spring-cloud #netflix-eureka

Вопрос:

Я не смог запустить клиент eureka, потому что, насколько я понял, он использует Джерси, как и spring boot. Поэтому я исключил джерси из клиента spring cloud eureka, как показано ниже, но у меня все та же ошибка pom.xml :

я удалил свой кеш IntelliJ, я удалил артефакт из .m2 перед выполнением чистой установки. Может быть, я что-то забыл?

Комментарии:

1. Я немного рассмотрю это здесь и дам вам знать

2. Хорошо, спасибо @spencergibb!

3. Могу ли я спросить, почему у вас есть spring-boot-starter-jersey и spring-cloud-starter-netflix-eureka-server как зависимость?

4. Поэтому удаление eureka-server и jersey starter исправляет ситуацию для меня. Можете ли вы ответить на мой вопрос выше?

5. @spencergibb, я не могу сказать ничего, кроме спасибо!! Это работает как шарм, но я боюсь, что это вызовет проблемы, если мне придется работать с джерси (я удалил spring-cloud-starter-netflix-eureka-server и spring-boot-starter-jersey, которые были ненужными)
