Quartz Scheduler - Cron Trigger表达式不起作用

Question

I am using Quartz scheduler in order to schedule some sequence of functionalities in my java project. 我正在使用Quartz调度程序来安排我的java项目中的一些功能序列。 I want the scheduler to start at 08:00:00 and to repeat for every four hours till 16:00:00. 我希望调度程序从08:00:00开始，每隔4小时重复一次，直到16:00:00。 I have tried doing this using CRONTrigger with below expression: 我尝试使用CRONTrigger以下表达式执行此操作：

"0 0 8,12,16 * * ?" “0 0 8,12,16 * *？”

But it is not working fine as expected. 但它没有像预期的那样正常工作。 Please help me in resolving this. 请帮我解决这个问题。 Thanks in advance. 提前致谢。
