  • У меня есть настройки ниже серверов.После книги весной облачный микро-сервер в действии.
    1. Сервер Zuul (порт 5555)
    2. Сервер Eureka (порт 8761)
    3. Сервер организации (порт 8081)
  • Сейчас,Я использую этот URL для получения информации с сервера лицензий.localhost: 5555 / api / organizationservice / v1 / organization / 35690f33-71b1-4996-83f8-93b8ca411848 /
  • Этот URL-адрес будет получать информацию с сервера организации через сервер zuul.

  • проблема в том, что вызов не удался и не получил никакой информации от сервера организации.

  • ОС: Macbook

  • Spring boot 2.1.4.RELEASE

  • Эврика
