使用Schedule Expression参数化EJB Scheduler

使用Schedule Expression参数化EJB Scheduler

而是使用程序化调度，这是一个示例：

@Singleton@Startuppublic class TriggerJob{    @EJB    //some injections    @Resource    private TimerService timerService;    @PostConstruct    public void init() {        createTimer();        //the following pre resolve my startup problem        try {        preparation();        } catch (CertificateVerificationException e) { e.printStackTrace();        }    }    @Timeout    public void timerTimeout() {        try {        preparation();        } catch (CertificateVerificationException e) {        e.printStackTrace();        }    }    private void createTimer() {        Scheduleexpression scheduleexpression = new Scheduleexpression();        scheduleexpression.second("30").minute("*/5").hour("*");        TimerConfig timerConfig = new TimerConfig();        timerConfig.setPersistent(false);        timerService.createCalendarTimer(scheduleexpression, timerConfig);        }    public void preparation(){        // my scheduled tasks    }}
