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");}
}

解决方案参考 SpringBoot的定时任务动态管理
缺陷：目前无法在运行期间增加Schedule以及stop、Start、Reset等管理。

本文章主要编写方式一的实现方案，主要从架构流程图配合代码进行说明。

}

一、启动时项目启动时，加载任务关联的触发器，并全量执行流程。
initLineRunner类：

package com.merak.hyper.automation.Scheduling;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.merak.hyper.automation.persist.entity.AutoTriggerInfo;
import com.merak.hyper.automation.persist.entity.BusWorkflow;

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.util.Iterator;
import java.util.List;
import java.util.Map;/*** 项目启动时，加载数字员工关联的触发器，并全量执行* @Date: 2020/12/25:16:00**/
@Component
@Order(1)
public class initLineRunner implements CommandLineRunner {public static final Logger log = LoggerFactory.getLogger(initLineRunner.class);private DateTimeFormatter df = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");@Autowiredprivate TaskService taskService;@Autowiredprivate IAutoTriggerInfoService triggerInfoService;@Autowiredprivate IBusWorkflowService workflowService;@Overridepublic void run(String... args) {log.info("项目启动:加载数字员工关联的触发器信息并全量执行," + df.format(LocalDateTime.now()));QueryWrapper wrapper = new QueryWrapper<>();wrapper.eq("wf_type", "3");//3:云托管wrapper.eq("wf_state", "1");List busWorkflows = workflowService.list(wrapper);List triggerInfos =  triggerInfoService.list();if( 0 == busWorkflows.size() || 0 == triggerInfos.size() ){log.info("数字员工关联的触发器信息不正确，员工记录数:"+busWorkflows.size()+",触发器记录数:"+triggerInfos.size());}else{//数字员工关联的触发器信息Map loadWfidAndTriggerInfo = CommonUtil.loadWfidAndTriggerInfo(busWorkflows,triggerInfos);Iterator> entries = loadWfidAndTriggerInfo.entrySet().iterator();while (entries.hasNext()) {Map.Entry entry = entries.next();String wfId = entry.getKey();BusWorkflow workflow = busWorkflows.stream().filter( t -> wfId.equals(t.getWfId()) ).findAny().orElse(null);if( null != workflow ){ScheduleUtil.start(new ScheduleTask(wfId,String.valueOf(workflow.getWfCreateuserId()),taskService), entry.getValue());}}log.info("数字员工关联的触发器信息全量执行完成，数字员工定时个数:"+loadWfidAndTriggerInfo.size()+","+df.format(LocalDateTime.now()));}}
}核心代码：
```javaScheduleUtil.start(new ScheduleTask(wfId,String.valueOf(workflow.getWfCreateuserId()),taskService), entry.getValue());

Scheduler管理工具类:启动、取消、修改等管理

package com.merak.hyper.automation.util;
import com.merak.hyper.automation.Scheduling.ScheduleTask;
import com.merak.hyper.automation.persist.entity.AutoTriggerInfo;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler;
import org.springframework.scheduling.support.CronTrigger;
import java.util.HashMap;
import java.util.Map;
import java.util.concurrent.ScheduledFuture;
/*** @author chenjun* @version 1.0* @ClassName: ScheduleUtil* @description: Scheduler管理工具类:启动、取消、修改等管理* @date 2022/10/22 14:37*/
public class ScheduleUtil {public static final Logger log = LoggerFactory.getLogger(ScheduleUtil.class);private static ThreadPoolTaskScheduler threadPoolTaskScheduler = SpringContextUtils.getBean(ThreadPoolTaskScheduler.class);//存储[数字员工wfI，dScheduledFuture]集合private static Map> scheduledFutureMap = new HashMap<>();/*** 启动** @param scheduleTask 定时任务* @param triggerInfo*/public static boolean start(ScheduleTask scheduleTask, AutoTriggerInfo triggerInfo) {String wfId = scheduleTask.getId();log.info("启动数字员工"+wfId+"定时任务线程" + scheduleTask.getId());ScheduledFuture scheduledFuture = threadPoolTaskScheduler.schedule(scheduleTask, new CronTrigger(triggerInfo.getLogicConfig()));scheduledFutureMap.put(wfId, scheduledFuture);return true;}/*** 取消** @param scheduleTask 定时任务*/public static boolean cancel(ScheduleTask scheduleTask) {log.info("关闭定时任务线程 taskId " + scheduleTask.getId());ScheduledFuture scheduledFuture = scheduledFutureMap.get(scheduleTask.getId());if (scheduledFuture != null && !scheduledFuture.isCancelled()) {scheduledFuture.cancel(false);}scheduledFutureMap.remove(scheduleTask.getId());return true;}/*** 修改** @param scheduleTask 定时任务* @param triggerInfo*/public static boolean reset(ScheduleTask scheduleTask, AutoTriggerInfo triggerInfo) {//先取消定时任务cancel(scheduleTask);//然后启动新的定时任务start(scheduleTask, triggerInfo);return true;}
}

ScheduleTask类：ScheduleTask任务类

package com.merak.hyper.automation.Scheduling;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;/*** @author chenjun* @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* @date 2022/10/22 14:38*/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;}/*** @param id      任务ID* @param service 业务类*/public ScheduleTask(String id, String userId, TaskService service) {this.id = id;this.userId = userId;this.service = service;}@Overridepublic void run() {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);}
}

/*** @author chenjun* @version 1.0* @ClassName: TaskService* @description: TaskService* @date 2022/10/22 14:42*/
public interface TaskService {/*** 业务处理方法* @param keyword 关键参数* @param userId*/void work(String keyword,String userId);
}/*** @description: TaskService实现类，具体执行定时调度的业务*/
@Service
public class TaskServiceImpl implements TaskService {public static final Logger log = LoggerFactory.getLogger(TaskServiceImpl.class);@Autowiredprivate IAutoDeviceInfoService deviceInfoService;@Overridepublic void work(String wfId,String userId) {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.*;
/*** @author chenjun* @version 1.0* @ClassName: ScheduledController* @description: scheduled Web业务层：启动、取消、修改等管理schedule* @date 2022/10/21 17:19*/
@RestController
@RequestMapping("/api/scheduled")
public class ScheduledController {public static final Logger log = LoggerFactory.getLogger(ScheduledController.class);@Autowiredprivate IAutoTriggerInfoService triggerInfoService;@Autowiredprivate 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
```java

import org.springframework.stereotype.Component;
/*** @author chenjun* @version 1.0* @ClassName: ScheduledHelper* @description:对外提供ScheduledHelper管理:创建、变更、停止* @date 2022/10/21 17:16*/
@Component
public class ScheduledHelper {public static final Logger log = LoggerFactory.getLogger(ScheduledHelper.class);/*** @description: 对外（Web)提供异步的Scheduleds增加操作*/@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) {//cron值改变，变更Schedule任务log.warn("数字员工["+scheduledApiVo.getWfId()+"]关联的触发器信息cron值改变，变更Schedule任务");TaskService taskService = SpringContextUtils.getBean(TaskService.class);ScheduleUtil.reset(new ScheduleTask(scheduledApiVo.getWfId(), scheduledApiVo.getUserId(), taskService), triggerInfo);}@Async("asyncTaskExecutor")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;/*** @author chenjun* @version 1.0* @ClassName: SpringContextUtils* @description: 加载Class对象* @date 2022/10/22 14:15*/

}

ScheduledApiVo类：

import java.io.Serializable;/*** @author chenjun* @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);******************** 分隔     ************************public static boolean SendQuartzMessage(String quartzUrl, String method, String webHookBody){boolean result = false;try{//org.apache.httpcomponents.httpclient sendPost，pom依赖如下dependencyString resp = HttpClientUtil.sendPostByJson(quartzUrl+"/"+method, webHookBody,0);if( "error".equals(resp) || resp.contains("405 Not Allowed")){log.error("调用任务调度中心消息发送失败,地址:"+quartzUrl);}else {JSONObject jsonObject = JSON.parseObject(resp);if( "200".equals(String.valueOf(jsonObject.get("code"))) ){result = true;}else{log.error("调用任务调度中心失败,msg："+String.valueOf(jsonObject.get("msg")));}}}catch (Exception e){log.error("调用任务调度中心失败,msg："+e.getMessage());}return result;}
