spring简单实现邮件任务调度

虽然是叫简单实现，但对我来说确实花了一番功夫，可想而知自己对新事物的学习能力，或者说英语理解能力还需要很大提高。现说一下自己碰到的几个大坑（小坑不说了，太多记不清了）。1.在applicationContext.xml中配置MethodInvokingJobDetailFactoryBean的时候我误以为可以直接配targetClass=XX.class，但任务就是不会自动执行。2.在调用任务方法的时候我取bean的时候写成ApplicationContext context = new ClassPathXmlApplicationContext("applicationcontext.xml");MailSenderService mailSender = (MailSenderService) context.getBean("mailsenderService");导致了可悲的结果，任务被重复创建，无数次的发送邮件，最后阿里云把我发送邮件的功能都停止了5分钟。其他的不说了，头有点昏，上代码吧！
