用的TimerTask和Timer

Question

brightonStores = BrightonUtil.getStoreInfo(file.getName(), dir.getAbsolutePath(),mailInfoST); 

    String status = "604"; 
    if (!brightonStores.isEmpty()) { 
     status = brightonStoreService.saveDeleteBrightonStore(brightonStores,mailInfoST); 
     storeLog.info("Adding Store records Status:: "+status); 
     if (status.equals("600")) {

     } else {

    BrightonUtil.setMailInfo(mailInfoST, true, false, "Error in reading data from Brighton Store file :: " + file.getName());

brightonStores = null; 
java.lang.Runtime.getRuntime().gc(); 

有问题，是否有可能reshedule的TimerTask的计时器..

Answer 1

不能在定时器中重新安排一个TimerTask。如果要更改运行任务的计划，则需要取消旧计时器并创建一个新计时器。
