Quartz学习之Lesson5-SimpleTrigger

SimpleTrigger should meet your scheduling needs if you need to have a job execute exactly once at a specific moment in time, or at a specific moment in time followed by repeats at a specific interval.

对于SimpleTrigger的描述以及，属性的设置，文档解释很清楚，可以直接看文档

SimpleTrigger Misfire Instructions

当一个SimpleTrigger由于某种原因（比如说Scheduler意外退出）突然退出，并且该SimpleTrigger重新运行时，所采取的执行策略，可以在改Trigger创建时指定该策略：

trigger = newTrigger()
    .withIdentity("trigger7", "group1")
    .withSchedule(simpleSchedule()
        .withIntervalInMinutes(5)
        .repeatForever()
        .withMisfireHandlingInstructionNextWithExistingCount())
    .build();
