为什么springboot应用程序从IDEA立即停止，但与mvn spring boot一起工作：运行

Question

当我使用命令“mvn-spring-boot:run”运行一个springboot应用程序时，它会启动tomcat并继续运行，但从主类“com.example.demo.DemoApplication”的Intellij启动时，它是相同的应用程序，然后立即关闭，并显示以下日志。如何从IDE运行它：

 :: Spring Boot ::                (v2.6.3)

2022-01-30 14:02:25.137  INFO 11024 --- [           main] com.example.demo.DemoApplication         : Starting DemoApplication using Java 1.8.0_291 on LAPTOP-1D3EOLKG with PID 11024 (C:\Users\SurajBahl\Downloads\demo\target\classes started by suraj.bahl in C:\Users\SurajBahl\Downloads\demo)
2022-01-30 14:02:25.139  INFO 11024 --- [           main] com.example.demo.DemoApplication         : No active profile set, falling back to default profiles: default

不久前，我在IntelliJ上遇到了同样的问题——对我来说，删除了. Ide和. iml文件夹，之后将项目重新导入IDE有所帮助。
