如何在启动时执行此EJB方法？

Question

我在这里不知所措。除了所有外部因素，这是一个EJB假设 在Wildfly 8.2.1.Final上运行att部署，但Wildfly是不均匀的 调用构造函数，从Exception中可以看出，它永远不会被抛出。

bean正在初始化一个Timer，这应该重复一些 定期任务iven在配置文件中。所有这些都在Java中运行 SE环境，但它的大部分内容都被删除，以消除对问题的干扰。

package jollobajano.bedtime.service.cleanupdaemon;

import javax.annotation.Resource;
import javax.ejb.ScheduleExpression;
import javax.ejb.Singleton;
import javax.ejb.Startup;
import javax.ejb.Timeout;
import javax.ejb.Timer;
import javax.ejb.TimerService;
import javax.inject.Inject;

import org.slf4j.Logger;

import jollobajano.bedtime.service.cleanupdaemon.config.CronExpression;
import jollobajano.bedtime.service.cleanupdaemon.config.JobConfiguration;
import jollobajano.bedtime.service.cleanupdaemon.config.ProducedConfig;
import jollobajano.bedtime.service.cleanupdaemon.config.ScheduleExpressionProvider;

@Singleton
@Startup
public class ScheduledCleanupBean {

    @Inject
    private Logger log;

    private Timer timer;

    @Inject
    @ProducedConfig
    private JobConfiguration configuration;

    @Inject
    private ScheduleExpressionProvider scheduleExpressionProvider;

    @Resource
    private TimerService timerService;

    public ScheduledCleanupBean() {
        System.err.println("### Constructing a ScheduledCleanupBean ### MATS");
        if (true) {
            throw new IllegalStateException("This is supposed to work, no?");
        }
    }

    @javax.ejb.PostConstruct
    public void init() {
        System.err.println("### Initializing a ScheduledCleanupBean ### MATS");
        if (configuration != null) {
            CronExpression cron = configuration.getCron();
            ScheduleExpression schedule = scheduleExpressionProvider.getScheduleExpression(cron);
            timer = timerService.createCalendarTimer(schedule);
            log.info("{} initialised.", this.getClass().getName());
        } else {
            log.info("{} not initialised. No configuration file found.", this.getClass().getName());

        }
    }

    @javax.ejb.PreDestroy
    public void exit() {
    }

    @Timeout
    public void execute(Timer timer) {
        for (String select : configuration.getSelect()) {
            log.info("SELECT: {}", select);
        }
    }

}

我不会厌倦整个日志，但它会在两个中提到 上下文，以便向我表明找到并注册了bean 在某些方面。

我想这很容易被新鲜的眼睛所发现。有人看到我的错误吗？
