spring boot的启动入口的方式

package com.zcp.springstart;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.context.ConfigurableApplicationContext;

import org.springframework.context.annotation.Bean;

@SpringBootApplication

public class App {

@Bean

public Runnable createRunnable(){

return new Runnable() {

@Override

public void run() {

System.out.println(">>>>>>>>>>>>runn---------");

}

};

}

public static void main(String[] args) {

ConfigurableApplicationContext context = SpringApplication.run(App.class, args);

context.getBean(Runnable.class).run();

}

}

说明:springboot的启动入口类，默认为配置类，故可以在该类中注入bean。
