spring提供的定时发送邮件功能一直深受广大web开发者的喜爱，最近忙里偷闲，自己写了个简单的例子以供大家参考，
首先从spring配置文件开始吧：


<!-- *****定时任务开始************** -->
   <!-- 定时发送邮件填写timesheet通知-->
        <bean id="JobServiceImpl" class="com.mdcl.timecard.mail.impl.MailManager"/>
 
   <!-- 定义调用对象和调用对象的方法 -->
        <bean id="projobtask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
            <property name="targetObject">
                <ref bean="JobServiceImpl"/>
            </property>
            <property name="targetMethod">
                <value>sendTimeSheetAlert</value>
            </property>
        </bean>
    <!-- 定义触发时间 -->
        <bean id="timecardSendMail" class="org.springframework.scheduling.quartz.CronTriggerBean">
            <property name="jobDetail">
                <ref bean="projobtask"/>
            </property>
            <!-- cron表达式 -->
            <property name="cronExpression">
                <value>0 0 0 ? * 5</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="timecardSendMail"/>
                    <!-- <ref bean="doTime"/> -->
                </list>
            </property>
        </bean>
