如何创建非持久性EJB 3.1计时器？

Question

使用NetBeans 7.1/GlassFish 3.1,我创建了一个新的TimerSessionBean.

@Stateless
public class NewTimerSessionBean implements NewTimerSessionBeanLocal {

    @Schedule(minute = "*", second = "0", dayOfMonth = "*", month = "*", year = "*", hour = "9-17", dayOfWeek = "Mon-Fri")
        @Override
        public void myTimer() {
            System.out.println("Timer event: " + new Date());
        }
}

如何声明计时器是非持久的？http://www.theserverside.com/news/1363578/EJB-31-A-Significant-Step-Towards-Maturity说有一个方法isPersistent但它属于Timer接口.

在阅读本文中有关EJB计时器潜在问题的描述之后,我提出了这个问题:http://www.coderanch.com/t/477104/EJB-JEE/java/Java-EE-timer-service-periodical

根据这篇文章,你可以通过在@Schedule上添加persistent = false来实现这一点
