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！

2.2 修改pom.xml文件

将原先的：

        
            
                org.springframework.boot
                spring-boot-maven-plugin
            
        

替换为：

        
            
                org.springframework.boot
                spring-boot-maven-plugin
                
                    
                        none
                    
                
            
        
 

二者择其一就OK！
