spring+quartz做的定时任务，tomcat启动没问题，就是定时任务不执行，是什么原因？

1.applicationContext_quartz.xml内容

<?xml version="1.0" encoding="UTF-8"?>

    <!-- 定时任务 -->
    <bean id="quartzAction" class="com.test.action.QuartzTaskAction"/>
    <!-- 第一步：指定执行的类的方法名 -->
        <bean id="xhhf_jd" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
           <property name="targetObject"><ref bean="quartzAction"/></property>
           <property name="targetMethod"><value>xhhfDates</value></property>
        </bean>
    <!-- 第二步：指定触发的类型 -->
        <bean id="xhhf_ct" class="org.springframework.scheduling.quartz.CronTriggerBean">
           <property name="jobDetail"><ref bean="xhhf_jd" /></property>
           <property name="cronExpression" value="0/2 * * * * ?" /> 
        </bean>
    <!-- 第三步：开启定时任务 -->
    <bean id="startQuertz" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
           <list>
              <ref bean="xhhf_ct"/>
           </list>
       </property>
    </bean>
</beans>

2.QuartzTaskAction.action内容

package com.test.action;

public class QuartzTaskAction{
    public void xhhfDates(){
        System.out.println("看我执行中。。。。");
    }
}

3.web.xml配置内容

 <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
            /WEB-INF/config/applicationContext_*.xml
        </param-value>
  </context-param>
