springboot-异步任务

springboot-异步任务

简单测试使用

异步任务可以简单理解为 前端先立刻返回OK之类的已经做完的信息 然后后端还在运行任务

编写service类 并通过注解告诉springboot为异步任务

package com.jie.service;

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

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

package com.jie.controller;

import com.jie.service.AsynService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class AsynController {
    @Autowired
    AsynService asynService;
    @RequestMapping("/hello")
    public String hello(){
        asynService.hello();
        return "ok";
    }
}
           

package com.jie;

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

//开启异步功能
@EnableAsync
@SpringBootApplication
public class SpringbootAsynApplication {

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

}
