为什么它会报这个异常信息

[解决办法]
你有导入quartz的jar包吗？
我之前的一个例子
- Java code
<!-- 要调用的工作类 --> <bean id="quartzJob" class="com.XXX.framework.listeners.Timer"></bean> <!-- 定义调用对象和调用对象的方法 --> <bean id="jobtask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> <!-- 调用的类 --> <property name="targetObject"> <ref bean="quartzJob" /> </property> <!-- 调用类中的方法 --> <property name="targetMethod"> <value>taskList</value> </property> </bean> <!-- 定义触发时间 --> <bean id="doTime" class="org.springframework.scheduling.quartz.CronTriggerBean"> <property name="jobDetail"> <ref bean="jobtask" /> </property> <!-- cron表达式 0秒 0分 0 点 ? * * --> <!-- * 表示所有值； ? 表示未说明的值，即不关心它为何值； - 表示一个指定的范围； , 表示附加一个可能值； / 符号前表示开始时间，符号后表示每次递增的值； --> <property name="cronExpression"> <value>0 0 0 ? * *</value> </property> </bean> <!-- 总管理类 如果将lazy-init='false'那么容器启动就会执行调度程序 --> <bean id="startQuertz" lazy-init="false" autowire="no" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <ref bean="doTime" /> </list> </property> </bean>
