我正在尝试使用代码星开发 Spring Boot 应用程序。我从代码星生成了示例代码，并在开始之前尝试在本地运行。我注意到我没有要运行的主应用程序。我加了一个。


    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class Main {
        public static void main(String[] args) {
            SpringApplication.run(Main.class, args);
        }
    
    }

当我尝试运行它时，给我一个错误。我找不到任何教程或文档来解决它。
