Question

我从重复服务获得了时间表数据。如何以用户友好的方式解析格式？这是样本计划格式。 0 13？ * MON * 请告诉我如何获得时间表格式的定义。

谢谢。

            Repeating.Service rService = Repeating.service(client, trigger.getId());
            Repeating repeat = rService.getObjectForRepeating();

            System.out.println("repeat schedule : " + repeat.getSchedule());

Answer 1

schedule属性的格式为Cron格式。

计划属性：

cron格式的计划。这是在UTC时区运行的。创建需要类型：串

下一个java脚本可以帮助你。

/**
* This script retrieves the Repeating trigger policies for a SoftLayer_Scale_Policy, then 
* it gets the schedule attribute and parses the value (Cron format) to human readable format.
