spring boot 项目运行报错

Question

使用IDEA创建的spring boot项目，目前是空项目，运行DemoApplication文件的时候，出现如下错误：

2019-05-16 17:36:41.215 INFO 22276 --- [ main] springboot02.demo.DemoApplication : Starting DemoApplication on lijinxiadeMacBook-Pro.local with PID 22276 (/data/yx/javacode/spring-boot-samples-master/demo/target/classes started by lijinxia in /data/yx/javacode/spring-boot-samples-master/demo)

2019-05-16 17:36:41.217 INFO 22276 --- [ main] springboot02.demo.DemoApplication : No active profile set, falling back to default profiles: default

2019-05-16 17:36:42.118 INFO 22276 --- [ main] springboot02.demo.DemoApplication : Started DemoApplication in 16.227 seconds (JVM running for 21.986)

application.properties 文件是空的

pom.xml文件的内容：

那这样看的话，是哪里出了问题那？

Answer 1

No active profile set, falling back to default profiles: default这行么？？这行是INFO级别，不是错误。
