springboot项目main函数启动

在controller包下新建appController类

package controller;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
@SpringBootApplication
public class appController extends SpringBootServletInitializer {

    public static void main(String[] args){
        SpringApplication.run(appController.class,args);
    }
    
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(appController.class);
    }
}
