- * 开发步骤：
- * 1、任务开发：在Spring Bean实例中，开发Job方法；
- * 2、注解配置：为Job方法添加注解 "@XxlJob(value="自定义jobhandler名称", init = "JobHandler初始化方法", destroy = "JobHandler销毁方法")"，注解value值对应的是调度中心新建任务的JobHandler属性的值。
- * 3、执行日志：需要通过 "XxlJobHelper.log" 打印执行日志；
- * 4、任务结果：默认任务结果为 "成功" 状态，不需要主动设置；如有诉求，比如设置任务结果为失败，可以通过 "XxlJobHelper.handleFail/handleSuccess" 自主设置任务结果；
