Add your start class in your pom：
<properties>
<!-- The main class to start by executing java -jar -->
<start-class>com.mycorp.starter.HelloWorldApplication</start-class>
</properties>
or
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>com.mycorp.starter.HelloWorldApplication</mainClass>
</configuration>
</plugin>
</plugins>
</build>
对于使用Gradle（而不是Maven）的用户：
springBoot {
mainClass = "com.example.Main"
}
