我在conf配置下custom里面加了一个timer配置,cron.com.backend.timer.StatisticJob=0 0 0 * * ? *;

我在conf配置下custom里面加了一个timer配置,
配置如下:
cron.com.backend.timer.OnlinePlayerJob=0 */5 * * * ?
cron.com.backend.timer.StatisticJob=0 0 0 * * ? *


在ioc下面,添加了一个js,如下:
var ioc = {
   "onlinePlayerJob" :{
      "type" :"com.backend.timer.OnlinePlayerJob",
      "fields":{dao:{refer:"backendDao"}}
   },
	"statisticJob" :{
	    "type" :"com.backend.timer.StatisticJob"
	 }
};



具体的操作如下:
public class StatisticJob implements Job {
	
private static final Logger log = Logger.getLogger(StatisticJob.class);

	@Override
	public void execute(JobExecutionContext context) throws JobExecutionException {
		
		long now =context.getFireTime().getTime();
		int nowTime = Long.valueOf(now/1000).intValue();
		int beginTime = nowTime - 24 * 60 * 60;
		
		
		Dao backendDao = LoginServerManager.getInstance().getDao();
		
		List<Dblog> serverlist = backendDao.query(Dblog.class,null);
		for (Dblog ser : serverlist) {
			try{
				SimpleDataSource source = DbConfigUtil.getInstance().GetDS(ser);
				if(source == null){
					continue;
				}
				Dao dao =  new NutDao(source);
				//要统计的物品初始化
				final HashMap<Integer, ItemDailyStatistic> itemList = new HashMap<>();
				for(ItemInfo item : ItemManger.getInstance().getItemList().values()){
					if(item.getNeedSaveLog() <= 1){
						continue;
					}
					ItemDailyStatistic info = new ItemDailyStatistic();
					info.setItemDataId(item.getItemId());
					info.setTime(nowTime);
					info.setServerId(ser.getServerId());
					itemList.put(item.getItemId(), info);
				}
				//统计货币初始化
				final HashMap<Integer, MoneyDailyStatistic> moneyList = new HashMap<>();
				for(int i = 1;i <= 9;i++){
					MoneyDailyStatistic info = new MoneyDailyStatistic();
					info.setMoneyType(i);
					info.setTime(nowTime);
					info.setServerId(ser.getServerId());
					moneyList.put(i, info);
				}
				
				itemDailyStatisticProduct(dao, now, beginTime, itemList);
				itemDailyStatisticCost(dao, now, beginTime, itemList);
				itemDailyStatisticRemain(backendDao,itemList,ser.getServerId());
				
				moneyDailyStatisticProduct(dao, now, beginTime, moneyList);
				moneyDailyStatisticCost(dao, now, beginTime, moneyList);
				moneyDailyStatisticRemain(backendDao,moneyList,ser.getServerId());
			}catch(Exception e){
				log.error(e,e);
			}
		}
	}




但是我不知道,配置的timer,是怎么执行的
