spring3.2+quartz2.21,怎么实现动态配置cronExpression，图片中为我目前的spring配置和java工作bean

在代码中改变的方案:
import java.text.ParseException;

import org.quartz.CronExpression;
import org.quartz.CronScheduleBuilder;
import org.quartz.CronTrigger;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.TriggerBuilder;
import org.quartz.TriggerKey;
import org.quartz.impl.StdSchedulerFactory;
import org.quartz.impl.matchers.GroupMatcher;
import org.quartz.utils.Key;


public class QuartzManager {
    
    public static void changeCronExpByName(String triggerName, String cronExpression) {
        try {
            Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();

            for (TriggerKey triggerKey : scheduler.getTriggerKeys(GroupMatcher
                    .triggerGroupEquals(Key.DEFAULT_GROUP))) {

                if (triggerKey.getName().equals(triggerName)) {

                    CronTrigger trigger = (CronTrigger) scheduler.getTrigger(triggerKey);

                    CronExpression.validateExpression(cronExpression);

                    CronTrigger reTrigger = TriggerBuilder.newTrigger().forJob(trigger.getJobKey())
                    // associated with the same job
                            .withIdentity(triggerName, Key.DEFAULT_GROUP)
                            // name can be different from original
                            .withSchedule(CronScheduleBuilder.cronSchedule(cronExpression)).build();

                    scheduler.rescheduleJob(triggerKey, reTrigger);

                    break;
                }
            }
        } catch (SchedulerException exp) {
            // do sth,maybe throw RunEx
            exp.printStackTrace();
        } catch (ParseException exp) {
            // do sth,maybe throw RunEx
            exp.printStackTrace();
        }
    }
}
