У меня есть Maven Spring Boot Project, который я настроил для запуска на сервере Tomcat 8.5.Я запускаю и разрабатываю его в Eclipse Java EE IDE.

Местоположение статического веб-содержимого: enter image description here

Что я не могу сделать, это: 1. прекратить повторное развертывание всего проекта (включая части Java и БД) каждый раз, когда я меняю статические ресурсы;2. просматривая консоль журналов, я вижу, что Spring Boot запускается два раза, поэтому я хочу, чтобы он запускался только один раз.

Пытался перейти на этот веб-сайт: https://www.logicbig.com/tutorials/spring-framework/spring-boot/restart-exclude.html

И думал, что нашел там ответ на свой вопрос, но по какой-то причине установка application.properties spring.devtools.restart.exclude игнорируется моимsystem.

Итак, чтобы решить эту проблему, я просто переместил содержимое HTML / CSS / JS своего веб-приложения из \ src \ main \ resources \ static в папку \ src \ main \ webapp.

Но проблема с «Spring Boot запускается дважды» все еще остается.Любая помощь будет полезна для меня.
