1.根据idea自带创建springboot项目
生成启动类
package com.lagou;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Springbootdemo2Application {
public static void main(String[] args) {
SpringApplication.run(Springbootdemo2Application.class, args);
}
}
