我最近决定将我的Springboot应用程序从Heroku迁移到2 EC2(Ubuntu(。一个用于PostgresDB，一个用于应用程序。我之前在迁移数据库时遇到了一些错误，但现在我已经让它正常工作，可以从PGadmin中查看其恢复的内容。现在，当我运行应用程序时，它会在添加模板时停止。它使用mvn-spring-boot:run和java-jar[应用程序的名称].jar来完成这项工作。下面是错误消息，我包含了在此之前发生的最后两条日志记录语句。我真的不知道该怎么做，因为它没有指向我在代码/src中的任何行或类，从我读到的东西来看，它似乎来自一个maven插件。如果我真的很绝望，我会考虑重建它，并在它稳定后导入我所有的类，但我希望有一个更简单的方法。

以下是我修复它的方法：
我在本地建造了它，看看我是否能更好地了解正在发生的事情。它建造成功了，我能够在本地使用它。我去了ide属性，看看JDK运行的是哪个版本，令我惊讶的是，它运行的是Java 11。我原以为Heroku在Java 8中运行Spring引导应用程序，但我错了。切换到JDK 11解决了这个问题。
