业务层方法

			public void prepare(MimeMessage mimeMessage) throws Exception {
		        MimeMessageHelper message = new MimeMessageHelper(mimeMessage,true,"UTF-8");
				message.setSubject("标题");
				message.setTo(user.getEmail());
				message.setFrom("***@163.com");
				Map model = new HashMap();
				model.put("user", user);
				String text = VelocityEngineUtils.mergeTemplateIntoString(
		    	velocityEngine, "registration-confirmation.vm","UTF-8", model);
		        message.setText(text, true);
		    }
		};
		try{
			this.mailSender.send(preparator);
			return true;
		}catch(MailException e) {
			System.out.println("没有这个邮箱");
			return true;
		}
	}
//将模板registration-confirmation.vm 存放在resourceLoaderPath的配置路径下（WEB-INF/） 模板见附件
//依赖javamail.jar,   j2ee4和j2ee5也有关系，使用时注意
