如何用java和glassfish实现每日计划任务?

最后我成功了,显然我和玻璃鱼有问题,我把他带走了,然后我回去补充。 但最后的代码是

@Singleton
@Startup

public class BackgroundJobManager {

@Schedule(hour="0", minute="0", second="0", persistent=false)
public void someDailyJob() {
    // Do your job here which should run every start of day.
    System.out.println("");
}

@Schedule(hour="*/1", minute="0", second="0", persistent=false)
public void someHourlyJob() {
    // Do your job here which should run every hour of day.
}

@Schedule(hour="*", minute="*/15", second="0", persistent=false)
public void someQuarterlyJob() {
    // Do your job here which should run every 15 minute of hour.
    System.out.println("Imprimir cada 15 mins");
}

@Schedule(hour="*", minute="*/1", second="0", persistent=false)
public void someMinuteJob() {
    // Do your job here which should run every minute of the hour.
    System.out.println("Imprimir cada 1 mins");
}

此代码位于@BalusC的帖子中 JSF managed bean for scheduled tasks using a timer

你的问题不是很清楚。然而,在行与行之间进行阅读,可以大致得出以下示例,使用 @Schedule 注释:

//change the statuses, from 'Executing...' to 'Uncomplete' every at 5pm 
@Schedule(hour = "17", persistent = false)
public void runEndOfDay() throws Exception {

    System.out.println("Tickets updated on - " + new Date());

    /*Set tickets to status 'Uncomplete' if Lodged without being completed until the end of business*/
    query = em.createQuery("update Ticket t set t.status = 'Uncompleted' where t.status = 'Executing...' or t.status = 'Paused...' or t.status = 'Missing...' or t.status = 'Lodged'");

    query.executeUpdate();
}

此方法在@Stateless会话bean(或EJB)对象中定义,每天17:00执行。该应用程序已作为.war文件部署在GlassFish 4.0中,并使用JSF 2.2 Framework创建
