javax.mail 发邮件 添加附件

标签：邮件

都是javax.mail 的使用，没有太多要讲的，代码贴上自己试验吧

private MimeMessage mailMessage; // 邮件对象
	private Multipart mp;// 附件添加的组件
	private List files = new LinkedList();// 存放附件文件

	/**
	 * 增加发送附件
	 * 
	 * @param filename
	 *            邮件附件的地址，只能是本机地址而不能是网络地址，否则抛出异常
	 * @return
	 */
	public boolean addFileAffix(String filename) {
		try {
			BodyPart bp = new MimeBodyPart();
			FileDataSource fileds = new FileDataSource(filename);
			bp.setDataHandler(new DataHandler(fileds));
			bp.setFileName(MimeUtility.encodeText(fileds.getName(), "utf-8", null)); // 解决附件名称乱码
			mp.addBodyPart(bp);// 添加附件
			files.add(fileds);
		} catch (Exception e) {
			System.err.println("增加邮件附件：" + filename + "发生错误！" + e);
			return false;
		}
		return true;
	}

	/**
	 * 设置邮件内容,并设置其为文本格式或HTML文件格式，编码方式为UTF-8
	 * 
	 * @param mailBody
	 * @return
	 */
	public boolean setBody(String mailBody) {
		try {
			BodyPart bp = new MimeBodyPart();
			bp.setContent("<meta http-equiv=Content-Type content=text/html; charset=UTF-8>" + mailBody, "text/html;charset=UTF-8");
			// 在组件上添加邮件文本
			mp.addBodyPart(bp);
		} catch (Exception e) {
			System.err.println("设置邮件正文时发生错误！" + e);
			return false;
		}
		return true;
	}

	/**
	 * 
	 * @param mailInfo
	 * @param content
	 * @param mailAddresses
	 * @param filename
	 * @return
	 * @throws MessagingException
	 */
	public boolean sendTextMail(MailSenderInfo mailInfo, String content, List<String> mailAddresses, String filename) throws MessagingException {
		MyAuthenticator authenticator = null;
		Properties pro = mailInfo.getProperties();
		if (mailInfo.isValidate()) {
			authenticator = new MyAuthenticator(mailInfo.getUserName(), mailInfo.getPassword());
		}
		Session sendMailSession = Session.getDefaultInstance(pro, authenticator);

		mailMessage = new MimeMessage(sendMailSession);
		mp = new MimeMultipart();// 生成附件组件的实例
		Address from = new InternetAddress(mailInfo.getFromAddress());
		mailMessage.setFrom(from);

		Address[] toMails = new Address[mailAddresses.size()];
		int i = 0;
		for (String mail : mailAddresses) {
			if (Tools.isNotNull(mail)) {
				toMails[i] = new InternetAddress(mail);
				i++;
			}
		}
		mailMessage.setSubject(mailInfo.getSubject());
		mailMessage.setSentDate(new Date());
		mailMessage.setRecipients(Message.RecipientType.TO, toMails);
		setBody(content);
		if (Tools.isNotNull(filename)) {// 添加附件
			addFileAffix(filename);
			mailMessage.setContent(mp);
			mailMessage.saveChanges();
		}

		try {
			Transport.send(mailMessage);
		} catch (Exception e) {
			e.printStackTrace();
		}

		return true;

	}

直接调用的函数：

/** 
* @throws MessagingException 
* @Title: mailsend 
* @Description: TODO 
* @param @param map 
* @return void 
* @throws 
*/ 
public void mailsend(String content, List<String> mailAddresses, String mailTitle,String filename) throws MessagingException { 

MailSenderInfo mailinfo = new MailSenderInfo(); 
mailinfo.setMailServerHost("xxxx"); 
mailinfo.setMailServerPort("xx"); 
mailinfo.setFromAddress("xx"); 
mailinfo.setUserName("xx"); 
mailinfo.setPassword("xx"); 
mailinfo.setValidate(true); 
mailinfo.setSubject(mailTitle); 
SimpleMailSender send = new SimpleMailSender(); 
send.sendTextMail(mailinfo, content, mailAddresses,filename); 
}
