【SpringBoot】啓動報錯:No active profile set, falling back to default profiles: default

使用Mac Idea創建springBoot工程，創建完畢啓動日誌如下：

/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/bin/java -XX:TieredStopAtLevel=1 -noverify-

Dspring.output.ansi.enabled=always -Dcom.sun.management.jmxremote -Dspring.jmx.enabled=true -

Dspring.liveBeansView.mbeanDomain -Dspring.application.admin.enabled=true -Dfile.encoding=UTF-8 -classpath

加載各種****.jar包

com.monkey.yb.springdemo.SpringdemoApplication

此問題產生的原因是缺少springBoot-web依賴，在pom.xml文件中添加spring-boot-starter-web即可，如下：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
