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 >Java代码：你讲在下面的代码中找到上面红色标注的那个方法
