* 【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；
