2 解决办法

2.1 添加main方法

main方法可以任意，例如：
结构目录：

public class hello {
    public static void main(String[] args) {
    }
}
但是不要在main方法上添加@SpringBootApplication注解！否则依旧报错！

方法二，当作普通的项目

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <phase>none</phase>
                    </execution>
                </executions>
            </plugin>
        </plugins>
 </build>
