Мы хотим запустить нашу основанную на Spring-Boot базу отдыха в стандартном окружении Googles App-Engine. Все работает нормально, кроме логирования. Мы не можем найти "плоский" вид всех журналов наших приложений. Мы находим журналы нашего приложения, сгруппированные в журнале request_log.
Мы регистрируемся с SLF4J (с помощью аннотации lomboks @ Slf4j, но это не должно иметь значения).
Мы пытались следовать этому Справочному руководству Google , чтобы настроить приложение Logback для ведения журнала Stackdriver.
- Добавление упомянутой зависимости Maven.
- Настройка конфигурации logback.xml.
Теперь приложение больше не запускается должным образом. По первому запросу мы получаем только следующие записи журнала под соответствующей записью request_log.

Похоже, что Spring-Boot не может правильно запуститься. Чего нам не хватает?
