几天来我一直在努力解决这个问题，但没有找到任何帮助，所以我会在这里询问。
我有这样的程序。如果我在本地计算机上的本地主机中对其进行测试，则可以正常工作。如果在ubuntu 18.04 tomcat中添加war，问题就开始了。 我已经在同一台服务器上测试了Jar，它可以工作。还测试了Heroku部署并在其中工作。也许我在制作战争包装Itellij时遇到问题，或者可能是什么问题？

您需要使用构造型注释之一，以使springboot识别用于自动接线的bean。在@Repository顶部使用ForestDataServicesInterface注释。
@Repository
public interface ForestDataServicesInterface extends JpaRepository<ForestDataMaaamet, Integer> {
@Query(value = "SELECT * FROM public.ff2", nativeQuery = true)
List<ForestDataMaaamet> findAll();
@Query(value = "SELECT * FROM public.ff2 where iscorrect = true", nativeQuery = true)
List<ForestDataMaaamet> findCorrectForestData();
}
您可以使用以下任何注释，但由于您的界面是存储库，因此建议使用@Repository
