Springboot开启异步任务

package com.example.scheduldemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableAsync;

@SpringBootApplication
@EnableAsync
public class SchedulDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(SchedulDemoApplication.class, args);
    }

}

package com.example.scheduldemo.service;

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

@Service
public class AsyncService {

    @Async
    public void hello(){
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("业务进行中。。。");
    }
}

package com.example.scheduldemo.controller;

import com.example.scheduldemo.service.AsyncService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController

    @Autowired
    AsyncService asyncService;

    @GetMapping("/hello")
    public String hello(){
        asyncService.hello();
        return "success";
    }
}
