Job实现类：

package cn.yrm.web.job;

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

@DisallowConcurrentExecution
public class MyJob implements Job {

    public void execute(JobExecutionContext arg0) throws JobExecutionException {
        // TODO Auto-generated method stub
        System.out.println("my job execute");
    }

}

ServletContextListener实现类：

package cn.yrm.web.listener;

import javax.servlet.ServletContextEvent;
