springboot启动后异步启动一个程序

@Async

@EnableAsync

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.scheduling.annotation.EnableAsync;
@SpringBootApplication

@EnableAsync

public class MyApplication {
public static void main(String[] args) {

        SpringApplication.run(MyApplication.class, args);

    }

}

1. 创建一个服务类： 创建一个服务类，包含你要异步执行的方法。

import org.springframework.scheduling.annotation.Async;

import org.springframework.stereotype.Service;
@Service

public class MyAsyncService {
@Async

    public void asyncMethod() {

        // 在这里编写你的异步方法逻辑

        System.out.println("异步方法被执行了");

    }

}

mainMyAsyncService

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.context.ApplicationContext;
@SpringBootApplication

@EnableAsync

public class MyApplication {
public static void main(String[] args) {

        ApplicationContext context = SpringApplication.run(MyApplication.class, args);

        MyAsyncService myAsyncService = context.getBean(MyAsyncService.class);

        myAsyncService.asyncMethod();

    }

}

main

@Async
