        } catch (Exception se) {
            se.printStackTrace();
        }
    }
}

job类

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class HelloJob implements Job{
    @Override
    public void execute(JobExecutionContext context)
            throws JobExecutionException {
        System.out.println("这是个Job!");
    }
}

 

1. 作业内容
2. 调度器
3. 执行时间

三者结合完成各种调度
