spring Qaurtz 作业调度

看了一些帖子,自己也做了个作业调度的例子,用simpleTriggerBean 能通,但用CronTriggerBean的时候就不行了.
我的配置如下:
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
  
  <bean id="scheduleDetail" 
   class="test.quartz.ScheduleDetail">
  </bean>
  
  <bean id="jobBean" 
   class="org.springframework.scheduling.quartz.JobDetailBean">
   <property name="jobClass" value="test.quartz.QuartzTest"/>
  </bean>
  
  <bean id="crontrigger" 
   class="org.springframework.scheduling.quartz.CronTriggerBean">
   <property name="jobDetail">
   <ref bean="jobBean"/>
   </property>
   <property name="cronExpression">
   <value>
   30 * * * * *
   </value>
   </property>
  </bean>

  <bean id="trigger"
   class="org.springframework.scheduling.quartz.SimpleTriggerBean">
   <property name="jobDetail">
   <ref bean="jobBean"/>
   </property>
   <property name="repeatInterval">
   <value>3000</value>
   </property>
  </bean>
  
  <bean id="scheduler" 
   class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
   <property name="triggers">
   <list>
   <ref bean="trigger"/>
                        <!--这个注释掉后能正常运行simpletrigger-->
   <ref bean="crontrigger"/>
   </list>
   </property>
  </bean>

如果没有注释报如下错误.

5 个解决方案

#1

注册触发器失败

#2

是的.错误应该就在这里
 Error creating bean with name 'scheduler' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is org.quartz.SchedulerException: Registration of jobs and triggers failed: null [See nested exception: java.util.NoSuchElementException] 
我试了,trigger,jobbean都能得到.但为什么不能注册到scheduler里面去呢???
这个NULL不知道是JOB为空还是TRIGGER为空.迷惑...

#3

怎么没人回啊,已经找到问题的原因了.
是这里<value> 
  30 * * * * * 
  </value>
不能分开写,正确的格式应该是<value>30 * * * * *</value>.最后的不能为*,为?的时候能正常工作.
哪位可以帮忙解释否?

这是因为Quartz的定时格式问题，你可以参考下面这个:
