Spring boot requires a startup class such

Package com. tianmaying; import org. springframework. boot. springApplication; import org. springframework. boot. autoconfigure. springBootApplication; import org. springframework. boot. web. servlet. servletComponentScan; @ SpringBootApplication @ ServletComponentScanpublic class BlogApplication {public static void main (String [] args) throws Exception {SpringApplication. run (BlogApplication. class, args );}}
