將這個檢測更新給禁用掉就可以了。。。
三個方法任選：

------方法1----------------配置文件
<!-- 定時任務 -->

 <bean id="z" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list></list>
</property>
<property name="quartzProperties"> 
<props>
<!-- 主要是這個參數 -->
<prop key="org.quartz.scheduler.skipUpdateCheck">true</prop> 
</props>
</property>
</bean>
-------方法2-----------------或者啟動參數
-Dorg.terracotta.quartz.skipUpdateCheck=true

-------方法3-----------------或者啟動的類中添加
System.setProperty("org.terracotta.quartz.skipUpdateCheck","true");
