简介： SpringBoot用注解实现异步--保证用户浏览体验

1.在springboot的Application类使用@EnableAsync开启异步

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableAsync;
@EnableAsync
@SpringBootApplication
public class SpringbootSecurityApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringbootSecurityApplication.class, args);
    }
}

2.在Service层需要异步的方法上使用@Async注解

package com.peng;
import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Service;
@Service
public class AnService {
    @Async
    public void AnSleep() throws InterruptedException {
        Thread.sleep(5000);
        System.out.println("ok>>>>>>>>>>>>>>>>>>>success");
    }
}

3.在controller层直接调用即可实现

package com.peng.controller;
import com.peng.AnService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class AnController {
    AnService anService;
    @Autowired
    public void setAnService(AnService anService) {
        this.anService = anService;
    }
@ResponseBody
@RequestMapping("/hello")
    public String hello() throws InterruptedException {
        anService.AnSleep();
        return "hello";
    }
}
