                DefaultSystemLog.getLog().error("定时任务异常", exception);
            }
        });
    }
}

Example 3 with Scheduler

use of cn.hutool.cron.Scheduler in project Jpom by dromara.

the class CronUtils method upsert.

/**
 * 添加任务、自动去重
 *
 * @param id   任务ID
 * @param cron 表达式
 * @param task 任务作业
 */
public static void upsert(String id, String cron, Task task) {
    Scheduler scheduler = CronUtil.getScheduler();
    Task schedulerTask = scheduler.getTask(id);
    if (schedulerTask != null) {
        CronUtil.remove(id);
    }
    // 创建任务
    CronUtil.schedule(id, cron, task);
    // 
    CronUtils.start();
}

Example 4 with Scheduler

use of cn.hutool.cron.Scheduler in project Jpom by dromara.

/**
 * 获取任务列表
 *
 * @return list
 */

        JSONObject jsonObject = new JSONObject();
        jsonObject.put("taskId", s);
        jsonObject.put("cron", scheduler.getPattern(s).toString());
