Quartz定时任务手动触发

我们使用quartz定时任务时，有手动触发执行任务的需要。此时，可以按照下面的方式触发定时任务立即执行。

public interface QuartzService {

    
    void quartzTrig(String jobName);

}

@Slf4j
@Service
public class QuartzServiceImpl implements QuartzService {

    @Autowired
    private ApplicationContext applicationContext;


    @Override
    public void quartzTrig(String jobName) {

        if (!StringUtils.hasText(jobName)) {
            log.error("parameter:jobName cannot be null or empty!");
            return;
        }

        Method[] methods = QuartzConfig.class.getDeclaredMethods();

        for (Method method : methods) {

            boolean present = method.isAnnotationPresent(Bean.class);

            if (present) {
                
                if ("org.springframework.scheduling.quartz.CronTriggerFactoryBean"
                        .equals(method.getGenericReturnType().getTypeName())) {

                    String[] values = method.getAnnotation(Bean.class).value();
                    if (values.length == 1) {

                        String beanName = values[0];
                        Object bean = applicationContext.getBean(beanName);

                        if (bean instanceof CronTriggerImpl) {

                            CronTriggerImpl trigger = (CronTriggerImpl) bean;

                            if (jobName.equals(trigger.getJobName())) {

                                try {

                                    SchedulerFactoryBean factoryBean = applicationContext.getBean(SchedulerFactoryBean.class);

                                    JobKey jobKey = new JobKey(trigger.getJobName());

                                    Scheduler scheduler = factoryBean.getScheduler();

                                    scheduler.triggerJob(jobKey);
                                    log.info("Trig job[{}] success!", jobName);

                                } catch (Exception e) {
                                    log.error("Trig job[{}] error!", jobName, e);
                                }
                            }
                        }
                    }
                }
            }
        }
    }

}
