spring quartz动态修改执行时间

1.获取schedule

 <bean name="startQuartz" lazy-init="false" autowire="no"
        class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="runJobTrigger" />
            </list>
        </property>
    </bean> 

@Resource(name="startQuartz")
private StdScheduler scheduler;

2.修改trigger

    <!--es数据备份定时任务-->
    <bean id="runJobTrigger11"
          class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="name">
            <value>name</value>
        </property>
        <property name="group">
            <value>group</value>
        </property>
        <property name="jobDetail">
            <ref bean="runJobDetail11" />
        </property>
        <property name="cronExpression">
            <value>0/2 * * ? * * *</value><!-- 每2秒一次 -->
        </property>
    </bean>
    <bean id="runJobDetail11"
          class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <!--这边自己设置>

    </bean>

        TriggerKey triggerKey = TriggerKey.triggerKey("name", "group");
        TriggerBuilder<Trigger> triggerBuilder = TriggerBuilder.newTrigger();
        triggerBuilder.withIdentity("esBackupTrigger", "es");
        triggerBuilder.startNow();
        triggerBuilder.withSchedule(CronScheduleBuilder.cronSchedule("0/"+day+" * * ? * * *"));
        System.out.println("0/"+5+" * * ? * * *");
        CronTrigger trigger = (CronTrigger) triggerBuilder.build();
        scheduler.rescheduleJob(triggerKey, trigger);

然后就修改了执行的时间，改成了5秒一次。
