实现任务模块

package com.sgfm.datacenter.sys;

import org.apache.log4j.Logger;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

public class DataTimingTask extends QuartzJobBean{
    private static Logger logger = Logger.getLogger(SystemMgr.class.getName());
    public DataTimingTask() {
        super();
    }
    @Override
    protected void executeInternal(JobExecutionContext arg0)
            throws JobExecutionException {
        // TODO Auto-generated method stub
        System.out.println("草根，你好！");
    }
}
