【问题描述】：
我不知道出了什么问题，但我创建了一个新的 Spring 应用程序并尝试运行它，但我总是收到此错误：

我错过了什么？我使用 Java SE 16 和 SDK 8
【问题讨论】：
-
你是如何尝试运行它的？
-
您可以尝试使用其他版本的 java（例如 java 11 LTS）
-
@Haidepzai RestController 并不是应用程序入口点的真正注解。您是否尝试通过运行 main 方法来运行此代码？您在编写此代码时是否遵循任何教程/书籍？
-
是的，我尝试运行 main 方法。是的，我按照教授的幻灯片进行了与幻灯片上相同的设置，但我认为我的 IntelliJ 有问题...
-
屏幕右上角转到 FinanceMgmntApplication 单击箭头查看选项并单击编辑配置。然后检查 JRE 是否来自 JDK 16。
