邮件推送实例，使用spring的注解方式

主要把老大的一点拆出来，以后随时使用，学习老大的：

  <!--开启这个配置，spring才能识别@Scheduled注解 --><task:scheduler id="scheduler" pool-size="10" /><task:executor id="executor" pool-size="5-10" queue-capacity="200" rejection-policy="CALLER_RUNS" /><task:annotation-driven executor="executor" scheduler="scheduler" />
