SpringBoot Schedule调度任务的动态管理方法是什么

学习文章要努力，但是不要急！今天的这篇文章《SpringBoot Schedule调度任务的动态管理方法是什么》将会介绍到等等知识点，如果你想深入学习文章，可以关注我！我会持续更新相关文章的，希望对大家都能有所帮助！

前言

定时任务动态管理分为两种方式：

方式一:Web前台配置Trigger触发器(关联Cron)、ThreadPoolTaskScheduler类创建Scheduler方式下进行Schedule调度任务的动态管理

方式二:基于已创建的Schedule调度任务的动态管理，即以组件类 @Scheduled注解声明Schedule调度，在启动程序前一次性初始化，如：

@Component
public class TestTask {
    private DateTimeFormatter df = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
    @Scheduled(cron = "0/2 * * * * ?")
    public void robReceiveExpireTask() {
        System.out.println(df.format(LocalDateTime.now()) + "测试测试");
    }
}

缺陷：目前无法在运行期间增加Schedule以及stop、Start、Reset等管理。

一、架构流程图

架构为SpringBoot + Spring + mybatis-plus

ScheduleTask类：ScheduleTask任务类

package com.merak.hyper.automation.Scheduling;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**
 * @version 1.0
 * @ClassName: ScheduleTask
 * @description: ScheduleTask，关联任务id、用户id和具体执行的TaskService类，实现Runnable类
 */
public class ScheduleTask implements Runnable {
    private static final int TIMEOUT = 30000;
    private String id;
    private String userId;
    private TaskService service;
    public static final Logger log = LoggerFactory.getLogger(ScheduleTask.class);
    public String getId() {
        return id;
    }

        log.info("ScheduleTask-执行数字员工消息的发送,id:"+ this.id + ",用户id:"+userId);
        service.work(this.id,this.userId);

    @Autowired
    private IAutoDeviceInfoService deviceInfoService;
    @Override

        try {
            log.info("定时任务：根据数字员工wfId"+ wfId +",用户id:"+userId+"，发送消息...");
            //sendRobotMsg(wfId,userId);
            Thread.sleep(200);
        } catch (InterruptedException e) {
            e.printStackTrace();

    }

二、通过WEB配置的变更，动态管理定时任务

ScheduledController类:scheduled Web业务层：启动、取消、修改等管理schedule

调度任务信息变更（如1：Trigger Cron变更 2：任务停止 3：任务新增加等）

package com.merak.hyper.automation.controller;
import com.merak.hyper.automation.common.core.domain.AjaxResult;
import com.merak.hyper.automation.common.core.vo.ScheduledApiVo;
import com.merak.hyper.automation.persist.entity.AutoTriggerInfo;
import com.merak.hyper.automation.persist.service.IAutoTriggerInfoService;
import com.merak.hyper.automation.util.ScheduledHelper;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
/**
 * @version 1.0
 * @ClassName: ScheduledController
 * @description: scheduled Web业务层：启动、取消、修改等管理schedule
 */
@RestController
@RequestMapping("/api/scheduled")
public class ScheduledController {
    public static final Logger log = LoggerFactory.getLogger(ScheduledController.class);
    @Autowired
    private IAutoTriggerInfoService triggerInfoService;
    @Autowired
    private ScheduledHelper scheduledHelper;
    @PostMapping("/add")
    public AjaxResult addScheduleds(@RequestBody ScheduledApiVo scheduledApiVo){
        AutoTriggerInfo autoTriggerInfo = triggerInfoService.getById(scheduledApiVo.getTriggerId());
        scheduledHelper.addScheduleds(scheduledApiVo,autoTriggerInfo);
        return AjaxResult.success();
    }
    @PostMapping("/reset")
    public AjaxResult resetScheduleds(@RequestBody ScheduledApiVo scheduledApiVo){
        AutoTriggerInfo autoTriggerInfo = triggerInfoService.getById(scheduledApiVo.getTriggerId());
        scheduledHelper.resetScheduleds(scheduledApiVo,autoTriggerInfo);
        return AjaxResult.success();
    }
    @PostMapping("/stop")
    public AjaxResult stopScheduleds(@RequestBody ScheduledApiVo scheduledApiVo){
        AutoTriggerInfo autoTriggerInfo = triggerInfoService.getById(scheduledApiVo.getTriggerId());
        scheduledHelper.stopScheduleds(scheduledApiVo);
        return AjaxResult.success();
    }
}
ScheduledHelper类：对外提供ScheduledHelper管理:创建、变更、停止

    /**

     */
    @Async("asyncTaskExecutor")
    public void addScheduleds(ScheduledApiVo scheduledApiVo, AutoTriggerInfo triggerInfo) {
        //addSchedule任务
        log.warn("创建原数字员工["+scheduledApiVo.getWfId()+"],同步启动Schedule任务");
        TaskService taskService = SpringContextUtils.getBean(TaskService.class);
        ScheduleUtil.start(new ScheduleTask(scheduledApiVo.getWfId(), scheduledApiVo.getUserId(), taskService), triggerInfo);
    }
    @Async("asyncTaskExecutor")
    public void resetScheduleds(ScheduledApiVo scheduledApiVo,AutoTriggerInfo triggerInfo) {

    public void stopScheduleds(ScheduledApiVo scheduledApiVo) {
        //移除Wfid，停止原Schedule任务
        log.warn("原数字员工["+scheduledApiVo.getWfId()+"]无效，同步停止Schedule任务");
        TaskService taskService = SpringContextUtils.getBean(TaskService.class);
        ScheduleUtil.cancel(new ScheduleTask(scheduledApiVo.getWfId(), scheduledApiVo.getUserId(), taskService));
    }
}

SpringContextUtils类：

package com.merak.hyper.automation.util;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext)
            throws BeansException {
        SpringContextUtils.applicationContext = applicationContext;
    }
    public static Object getBean(String name) {
        return applicationContext.getBean(name);
    }
    public static  T getBean(Class requiredType) {
        return applicationContext.getBean(requiredType);
    }
    public static  T getBean(String name, Class requiredType) {
        return applicationContext.getBean(name, requiredType);
    }
    public static boolean containsBean(String name) {
        return applicationContext.containsBean(name);
    }
    public static boolean isSingleton(String name) {
        return applicationContext.isSingleton(name);
    }
    public static Class getType(String name) {
        return applicationContext.getType(name);
    }
}

ScheduledApiVo类：

import java.io.Serializable;
/**
 * @version 1.0
 * @ClassName: ScheduledApiVo
 * @description: scheduled Web业务层Api传递参数Vo类
 */
public class ScheduledApiVo implements Serializable {
    private String wfId;
    private String userId;
    private String triggerId;
    //set get 略
}

最终：Web端通过发送Http请求 ，调用ScheduledHelper管理类接口，实现Scheduled创建、变更、停止操作

  log.info("3:云托管更新启动数字员工操作");
  ScheduledApiVo scheduledApiVo = new ScheduledApiVo();
  scheduledApiVo.setWfId(wfId);
  scheduledApiVo.setUserId(String.valueOf(updateUserId));
  scheduledApiVo.setTriggerId(newTriggerInfo.getId());
  String webHookBody = JSON.toJSONString(scheduledApiVo);
  EmsApiUtil.SendQuartzMessage(url, "add", webHookBody);
