代码实现

邮件工具类

/**
 * 邮件工具类
 * @author Administrator
 */
public class MailUtil {
	// 邮件发送者
	private JavaMailSender javaMailSender;
	// 发送人
	private String fromAddress;

	public void setJavaMailSender(JavaMailSender javaMailSender) {
		this.javaMailSender = javaMailSender;
	}

	public void setFromAddress(String fromAddress) {
		this.fromAddress = fromAddress;
	}

	/**
	 * 	发送邮件 
	 * @param toAddress 邮件接收者，多者用逗号分隔
	 * @param subject 主题
	 * @param text 邮件正文(内容)
	 * @throws MessagingException
	 */
	public void sendMail(String toAddress, String subject, String text) throws MessagingException {
		// 创建邮件
		MimeMessage mime = javaMailSender.createMimeMessage();
		// 邮件包装工具
		MimeMessageHelper helper = new MimeMessageHelper(mime);
		// 主题
		helper.setSubject(subject);
		// 发件人
		helper.setFrom(fromAddress);
		// 收件人
		helper.setTo(toAddress);
		// 邮件正文
		helper.setText(text);
		// 发送邮件
		javaMailSender.send(mime);
	}
}

业务逻辑代码

public void sendStoreAlertMail() throws MessagingException {
		// 查看是否存在需要预警的商品
		List<StoreAlert> storeAlertList = storedetailDao.getStoreAlertList();
		int cnt = storeAlertList == null ? 0 : storeAlertList.size();
		if (cnt > 0) {
			try {
				SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
				// 发送邮件
				/*
				subject = 库存预警_时间:[time] => 库存预警_时间:2017-05-04 10:42:45
				text=尊敬的客户，有[count]种商品已经预警了，请登陆系统查看
				*/
				mailUtil.sendMail(toAddress, subject.replace("[time]", sdf.format(new Date())),
						text.replace("[count]", String.valueOf(cnt)));
			} catch (MessagingException e) {
				e.printStackTrace();
				throw new ErpException("发送预警邮件失败");
			}
		} else {
			throw new ErpException("没有需要预警的商品");
		}
	}

action处理

public void sendAlertMail() {
	try {
		storedetailBiz.sendStoreAlertMail();
		// 将提示信息写给前端
		ajaxReturn(true, "发送成功");
	} catch (MessagingException e) {
		ajaxReturn(false, "无法发送邮件");
		e.printStackTrace();
	} catch (ErpException e) {
		ajaxReturn(false, e.getMessage());
	}
}
