如何告诉Spring Boot可执行jar使用哪个主类？

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>
