类 ScheduledTaskRegistrar

字段详细资料

• CRON_DISABLED

  public static final String CRON_DISABLED

  A special cron expression value that indicates a disabled trigger: "-".

  This is primarily meant for use with addCronTask(Runnable, String) when the value for the supplied expression is retrieved from an external source — for example, from a property in the Environment.

  5.2
