使用Application Scoped Managed Bean在JSF 2中安排任务

Question

我是JSF的新手，我正在尝试创建一个安排简单任务的方法。我使用注释＆＃34; Schedule＆＃34;创建了下面的任务。从ejb 3.2开始，我用注释＆＃34; ApplicationScoped＆＃34;创建了托管bean。 每次启动我的服务器时，构建器都会运行并打印该行，但带注释的方法不起作用。 我使用的是JSF 2.0，Tomcat 8.0

package br.ifsp.eBlueCard.bean
import java.util.List;
import javax.ejb.Schedule;
import javax.faces.bean.ApplicationScoped;
import javax.faces.bean.ManagedBean;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import br.ifsp.eBlueCard.entities.ECard;
import br.ifsp.eBlueCard.repository.ECardRepository;

@ManagedBean(eager=true)
@ApplicationScoped
public class TimerEmailBean {
private List<ECard> ecards;

public TimerEmailBean(){
    System.out.println("I'm alive.");
}

@Schedule(second="*", minute="*", hour="*")
public void listaECards(){
    System.out.println("Hi, me too.");
    /*EntityManagerFactory factory = Persistence.createEntityManagerFactory("eBlueCard");

    EntityManager manager = factory.createEntityManager();

    ECardRepository ecr = new ECardRepository(manager);
    try{
    this.ecards = ecr.buscaEcardsAtivos();
    }catch(Exception e){
        System.out.println("VAZIO");
    }
    if(this.ecards.size() > 0){
        for(int i=0;i<ecards.size();i++){
            System.out.println(this.ecards.get(i).getCliente().getNome());
        }
    }else{
        System.out.println("VAZIO");
    }*/
}

public List<ECard> getEcards() {
    return ecards;
}

public void setEcards(List<ECard> ecards) {
    this.ecards = ecards;
}
}
