<!-- 配置调度程序quartz ，其中配置JobDetail有两种方式-->
<!--方式一：使用JobDetailBean，任务类必须实现Job接口 -->
<!-- <bean id="myjob" class="org.springframework.scheduling.quartz.JobDetailBean">
<property name="name" value="exampleJob"></property>
<property name="jobClass" value="test.Test"></property>

<!--运行时请将方式一注释掉！ -->
<!-- 方式二：使用MethodInvokingJobDetailFactoryBean，任务类可以不实现Job接口，通过targetMethod指定调用方法-->
