就要用到spring+velocity+javamail这3个玩意，其实只用了spring，因为其他2个都被spring集成了。

上面这个类实际上是个发送邮件的工具类，我们只要设置好参数后调用想要的sendXXX()就可以了。如下：
1
//注册完马上发送邮件2
MailSenderService mailSender=this.getMailsenderService();3
mailSender.setTo(form.getEmail());4
mailSender.setSubject("来自worthtech的邮件");5
mailSender.setTemplateName("mail.vm");//设置的邮件模板6
Map model=new HashMap();7
model.put("username", form.getUserName());8
String url=request.getRequestURL().toString();9
url=url.substring(0, url.lastIndexOf("/"));10
model.put("url", url);11
model.put("email", "gjni@worthtech.net");12
mailSender.sendWithTemplate(model);13
System.out.println("邮件发送成功！");
下面的是spring配置
