这篇文章主要介绍了SpringBoot Schedule调度任务的动态管理方法是什么的相关知识，内容详细易懂，操作简单快捷，具有一定借鉴价值，相信大家阅读完这篇SpringBoot Schedule调度任务的动态管理方法是什么文章都会有所收获，下面我们一起来看看吧。
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。

}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.vo.ScheduledApiVo;

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);

}
}
ScheduledHelper类：对外提供ScheduledHelper管理:创建、变更、停止

}
@Async("asyncTaskExecutor")
public void resetScheduleds(ScheduledApiVo scheduledApiVo,AutoTriggerInfo triggerInfo) {
