Question

Я установил базовое c приложение JHipster Microservice с MySQL DB. JHipster показывают удачный строительный проект. после того, как я запустил проект с помощью команды . / gradelw , я получил ОШИБКУ 6775 на сервере Eureka. как я могу это исправить?

Answer 1

Эта ошибка исходит от EUREKA. Загрузите jhipster-registry из: jhipster-registry репозитория github переместите его куда хотите и добавьте к нему права чтения и записи с помощью этой команды:

chmod 755 jhipster-registry-<version>.jar

замените версию на версию файла JAR, которую вы загружаете. запустите файл jar с помощью этой команды:

java -jar jhipster-registry-<version>.jar --spring.security.user.password=admin --jhipster.security.authentication.jwt.secret=my-secret-key-which-should-be-changed-in-production-and-be-base64-encoded --spring.cloud.config.server.composite.0.type=native --spring.cloud.config.server.composite.0.search-locations=file:./central-config

не забудьте заменить версию на ту версию, которую вы скачали.

после успешного запуска вы можете запустить микросервис.
