查看
java.util.Timer
,如果还不足以阅读-纯java cron兼容调度器 石英似乎是更好的选择。这可能会帮助您设置石英。试试看
public class SendEmail extends TimerTask{
public static void main(String[] args){
Timer t = new Timer();
t.schedule(new SendEmail(), 0, 9000); //send email every 9 seconds
}
@Override
public void run() {
// TODO Auto-generated method stub
//Your email syntax here
}
}您想要一个Java解决方案(将电子邮件任务安排在代码中执行)还是想要一个在特定时间运行应用程序的外部解决方案?Quartz或OS,您想要使用的两个选项——老实说,计划任务(Linux上的Cron)就是您想要的。如果你有一个网络系统石英是伟大的。
