spring+velocity+javamail发送模板邮件实例源码介绍



spring+velocity+javamail发送模板邮件实例源码介绍。当我们注册完的时候系统会提示有一封邮件发送到了你的邮箱，如何做呢？

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。
先看代码

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
2MailSenderService mailSender=this.getMailsenderService();
3mailSender.setTo(form.getEmail());
4mailSender.setSubject(“来自worthtech的邮件”);
5mailSender.setTemplateName(“mail.vm”);//设置的邮件模板
6Map model=new HashMap();
7model.put(“username”, form.getUserName());
8String url=request.getRequestURL().toString();
9url=url.substring(0, url.lastIndexOf(“/”));
10model.put(“url”, url);
11model.put(“email”, ”gjni@worthtech.net”);
12mailSender.sendWithTemplate(model);
13System.out.println(“邮件发送成功！”);

下面的是spring配置
