springboot异步任务

 在Service类声明一个注解@Async作为异步方法的标识

package com.qf.sping09test.service;

import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Service;

@Service
public class AsyncService {

    //告诉spring这是一个异步的方法
    @Async
    public void hello(){
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("数据正在处理...");
    }


}

controller

package com.qf.sping09test.controller;

import com.qf.sping09test.service.AsyncService;
import org.sprin
