springboot项目main函数启动的操作

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);
   }
}

测试：
