  </property>

  <property

   <list>

    <ref
local="testTrigger" />

   </list>

  </property>

 </bean>

 <bean id="testTrigger"
class="org.springframework.scheduling.quartz.CronTriggerBean">

  <property
name="jobDetail">

   <ref
bean="testJobDetail" />

  </property>

  <property
name="cronExpression">

   <!--
过一秒开始，每间隔两秒执行 -->

   <value>1/2
* * * * ?</value>

  </property>

 </bean>

 <bean id="testJobDetail"

  class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">

  <property
name="targetObject">

   <ref
bean="scheduleTimerTest" />

  </property>

  <property
name="targetMethod">

   <value>timeTest</value>

  </property>

  <property
name="concurrent" value="false" />

 </bean>

 <bean id="scheduleTimerTest"
class="com.lrq.timer.ScheduleTimerTest"></bean>

</beans>

这是配置文件,引入即可:

需要注意的地方:

1
jar包问题:ssh+\spring-context-support-3.2.1.RELEASE.jar+quartz-1.6.6.jar+quartz-all-1.6.6.jar

配置文件:

1 <bean id="scheduleTimerTest"
class="com.lrq.timer.ScheduleTimerTest"></bean>需要定时器执行的目标类;

需要被上面的定时器引用:

 <property
name="targetObject">

   <ref
bean="scheduleTimerTest" />

  </property>

  <property
name="targetMethod">

   <value>timeTest</value>

  </property>

2执行周期匹配表达式;请参看文档;

核心思路还是依赖注入;
