這篇文章給大家介紹怎樣進行SpringBoot基于數據庫的定時任務統一管理的實現,內容非常詳細,感興趣的小伙伴們可以參考借鑒,希望對大家能有所幫助。
定時任務1
import lombok.extern.slf4j.Slf4j;/** * @author Created by niugang on 2019/12/24/15:29 */@Slf4jpublic class TaskTest { public void task1() { log.info("反射調用測試[一]類"); }}
定時任務2
import lombok.extern.slf4j.Slf4j;/** * @author Created by niugang on 2019/12/24/15:54 */@Slf4jpublic class TaskTest2 { public void task2() { log.info("反射調用測試[二]類"); }}
配置類

} } }, "0/5 * * * * ?");

} } }
catch (Exception e1) { e1.printStackTrace();
} };
CronTask cronTask = new CronTask(runnable, cron);
ScheduledTask scheduledTask = taskRegistrar.scheduleCronTask(cronTask);
//scheduledTask.cancel(); 取消定時任務 } }
@Data private static class TaskRecord { private String classPath;
private String executeMehod;
private String cron;
//可以在增加一個type 執行其他類型的定時任務 }}
