springboot-异步任务

service.TasksService#

package com.lu.service;


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

@Service
public class TasksService {

    @Async//告诉springboot这是个异步任务
    public void Hello(){
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("数据正在处理中");
    }
}

controller.textController#

package com.lu.controller;


import com.lu.service.TasksService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TextController {
    @Autowired
    TasksService tasksService;

    @RequestMapping("/hello")
    public String hello(){
        tasksService.Hello();
        return "你好啊";
    }
}

运行主类#

package com.lu;

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


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

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

}
