Вопрос:
Поэтому я создал два микросервиса, один для настройки, а другой для регистрации, а также локальный репозиторий с именем agri-config. После настройки различных микросервисов, когда я запускаю службу регистрации, у меня возникает эта ошибка, и я хочу уточнить, что я использую версию 2020.0.0 spring cloud.

Ответ №1:
На самом деле, вчера я столкнулся с аналогичной проблемой. После небольшого поиска в Google я нашел этот очень интересный список изменений от самих spring. По-видимому, они изменили синтаксис синтаксического анализа файла свойств. Я еще не полностью ознакомился с ним, но для решения вашей насущной проблемы вам необходимо добавить
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>
Я также нашел видео Фила Уэбба, объясняющего, что нового в Spring Boot 2.4. Очень интересно. Я посмотрю его завтра. Где он, казалось, прошел через эти подводные камни. Опять же, я не полностью проверил это, но на данный момент эта зависимость решает все мои проблемы. Я надеюсь, что это вам тоже поможет, а если нет, я постараюсь помочь, если смогу.
Приятного вечера
