SpringBoot Schedule 스케줄링 작업의 동적 관리 방법은 무엇입니까?

머리말

예약된 작업을 동적으로 관리하는 방법에는 두 가지가 있습니다.

방법 1: 웹 프런트 엔드 구성 트리거 트리거(Cron과 연결됨), ThreadPoolTaskScheduler 클래스는 스케줄러 모드를 생성하여 일정 예약 작업을 동적으로 관리합니다.

방법 2: 기반 생성된 Schedule 스케줄링 작업의 동적 관리, 즉 컴포넌트 클래스의 @Scheduled 주석으로 Schedule 스케줄을 선언하고 프로그램 시작 전에 한 번 초기화합니다. 예:

@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");
    }
}

Defect: 현재는 불가능합니다. 실행 중 일정 및 중지, 시작, 재설정 및 기타 관리를 추가합니다.

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;
    }
    /**
     * @param id      任务ID

    }
    @Override
    public void run() {
        log.info("ScheduleTask-执行数字员工消息的发送,id:"+ this.id + ",用户id:"+userId);

    @Autowired

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.util.ScheduledHelper;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
/**

 * @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) {

        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;

    }
    public static Class<? extends Object> getType(String name) {
        return applicationContext.getType(name);
    }
}

ScheduledApiVo类：

import java.io.Serializable;
/**

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);
