Я использую привод с пружинной загрузкой для сбора метрик моего приложения. Я развертываю приложение как файл war на tomcat.
Версия загрузки Spring: 2.1.7.RELEASE Версия Tomcat: 8
При развертывании я получаю сообщение об ошибке ниже:
2019-09-30 11:42:24 [ERROR] - [localhost-startStop-1] - [] - [o.s.b.SpringApplication] - Application run failed

Когда я удаляю зависимость привода из файла pom.xml, приложение развертывается и работает правильно.
