/**
* 【类方式任务开发即将废弃,建议采用方法方式开发,参考:com.xxl.job.executor.service.jobhandler.SampleXxlJob 】
*
* 任务Handler示例(Bean模式)
*
* 开发步骤:
* 1、继承"IJobHandler":“com.xxl.job.core.handler.IJobHandler”;
* 2、注册到Spring容器:添加“@Component”注解,被Spring容器扫描为Bean实例;
* 3、注册到执行器工厂:添加“@JobHandler(value="自定义jobhandler名称")”注解,注解value值对应的是调度中心新建任务的JobHandler属性的值。
* 4、执行日志:需要通过 "XxlJobLogger.log" 打印执行日志;
