Springboot任务之异步任务的使用详解

package com.tian.asyncdemo.service;

import org.springframework.stereotype.Service;

@Service
public class AsyncService {
    public void hello() {
        try {
            System.out.println("数据正在处理");
            Thread.sleep(3000);
            System.out.println("数据处理完成");
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

package com.tian.asyncdemo.controller;

import com.tian.asyncdemo.service.AsyncService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.WEB.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

    @RequestMapping("/hello")
    public String hello() {
