执行的动作：实现job

package com.dinfo.xyk.utils;


import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;


public class Test implements Job {


public void execute(JobExecutionContext arg0) throws JobExecutionException {
System.out.println("dasafda");
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}


}
