邮件开发项目的总结

这个月主要是做邮件开发项目，熟悉了javamail的一些应用，了解了邮件Mime格式。还有制作邮件内容的CKEditor编辑器（搞了很头疼。。）。算是做下总结了，以避免忘记。

1，javaMail的使用，用一个发送邮件的demo吧。

public class MailSendAction {
    private static final Logger logger = Logger.getLogger(MailSendAction.class);

    public static void main(String[] args) {
        try {
            String hostName = "smtp.qq.com";
            String EMAIL_NAME = "258072761";
            String EMAIL_PASSWORD = "*********";
            MailSendAction mailAction = new MailSendAction();
            Properties props = System.getProperties(); // 获得系统属性对象
             props.put("mail.smtp.host", hostName); // 设置SMTP主机
            props.put("mail.smtp.auth", "true");
            Session session = Session.getDefaultInstance(props);
            
            // 发送开始
             Transport transport = session.getTransport("smtp");
             transport.connect((String) props.get("mail.smtp.host"),
             EMAIL_NAME, EMAIL_PASSWORD);
    
            // transport.sendMessage(message,
            // message.getRecipients(Message.RecipientType.TO));
             transport.close();
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

    public MimeBodyPart createAttachment(String fileName) throws Exception {
        MimeBodyPart attachementPart = new MimeBodyPart();
        FileDataSource fds = new FileDataSource(fileName);
        attachementPart.setDataHandler(new DataHandler(fds));
        String[] strs = fds.getName().split("_",2);
        if(strs.length>1)
            attachementPart.setFileName(strs[1]);
        else
            attachementPart.setFileName(fds.getName());
        return attachementPart;
    }

    public MimeBodyPart createContent(String body, String fileName)
            throws Exception {
        MimeBodyPart contentBody = new MimeBodyPart();
        MimeMultipart contentMulti = new MimeMultipart("related");
        // 正文文本部分
        MimeBodyPart textBody = new MimeBodyPart();
        textBody.setContent(body, "text/html;charset=gbk");
        contentMulti.addBodyPart(textBody);

        // 正文图片部分
        MimeBodyPart jpgBody = new MimeBodyPart();
        FileDataSource fds = new FileDataSource(fileName);
        jpgBody.setDataHandler(new DataHandler(fds));
        jpgBody.setContentID("logo_jpg");
        contentMulti.addBodyPart(jpgBody);

        contentBody.setContent(contentMulti);
        return contentBody;
    }

    /**
     * 
     * @param body
     * @param fileName
     * @return
     * @throws Exception
     */
    public MimeBodyPart createContent(String body, List<String> imgFileNames)
            throws Exception {
        MimeBodyPart relatedBodyPart = new MimeBodyPart();
        MimeMultipart relatedMulti = new MimeMultipart("related");
        // 正文文本部分
        MimeBodyPart alternativeBodyPart = new MimeBodyPart();
        MimeMultipart alternativeMulti = new MimeMultipart("alternative");
        
        MimeBodyPart textBody = new MimeBodyPart();
        textBody.setContent(body, "text/html;charset=gbk");
        alternativeMulti.addBodyPart(textBody);
        alternativeBodyPart.setContent(alternativeMulti);
        relatedMulti.addBodyPart(alternativeBodyPart);
        
        // 内置资源部分
        int i = 0;
        for (String imgFileName : imgFileNames) {
            MimeBodyPart jpgBody = new MimeBodyPart();
            FileDataSource fds = new FileDataSource(imgFileName);
            jpgBody.setDataHandler(new DataHandler(fds));
            jpgBody.setContentID("img" + i);
            relatedMulti.addBodyPart(jpgBody);
            i++;
        }
        relatedBodyPart.setContent(relatedMulti);
        return relatedBodyPart;
    }

    /**
     * 
     * @param session
     * @return
     * @throws Exception
     */
    public MimeMessage createMessage(String subject, String body,
            Session session, List<String> imgFileNames,
            List<String> attacheFilePaths) throws Exception {


        MimeMessage msg = new MimeMessage(session);
        msg.setSubject(subject, "gb2312");

        // 创建邮件的各个MimeBodyPart部份

        // 创建附件
        List<MimeBodyPart> attachmentList = new ArrayList<MimeBodyPart>();

        for (String attachFilePath : attacheFilePaths) {
            attachmentList.add(createAttachment(attachFilePath));
        }

        MimeBodyPart content = createContent(body, imgFileNames);

        // 将邮件中各个部份组合到一个"mixed"型的MimeMultipart对象
        MimeMultipart allpart = new MimeMultipart("mixed");
        for (MimeBodyPart mimeBodyPart : attachmentList) {
            allpart.addBodyPart(mimeBodyPart);
        }
        allpart.addBodyPart(content);

        // 将上面混合型的 MimeMultipart对象作为邮件内容并保存
        msg.setContent(allpart);
        return msg;

    }
    

    
    public static String sendMail(String emlPath, String to){
        try {
            String hostName = "smtp.qq.com";
            String EMAIL_NAME = "258072761";
            String EMAIL_PASSWORD = "hhysbyj123456";
            String from = "258072761@qq.com";
            Properties props = System.getProperties(); // 获得系统属性对象
            props.put("mail.smtp.host", hostName); // 设置SMTP主机
            props.put("mail.smtp.auth", "true");
            Session session = Session.getDefaultInstance(props);
            InputStream fis = new FileInputStream(emlPath);
            MimeMessage message = new MimeMessage(session, fis);
            message.setRecipients(Message.RecipientType.TO, (Address[])
                     InternetAddress.parse(to));

            // 发送开始
            Transport transport = session.getTransport("smtp");
            transport.connect((String) props.get("mail.smtp.host"),
            EMAIL_NAME, EMAIL_PASSWORD);
    
            transport.sendMessage(message,
            message.getRecipients(Message.RecipientType.TO));
            transport.close();
            return "发送邮件成功";
        
    } catch (Exception e) {
        e.printStackTrace();
    }
    return "";
    }
}

2，关于ckeditor编辑器的使用

<tr>
                    <th width="15%">邮件内容</th>
                    <td id= "mailContent" width="85%" colspan="3">
                        <textarea id="content" name="content" style="display:none"></textarea>
                        <script type="text/javascript"> 
                        
                          CKEDITOR.replace('content',{filebrowserUploadUrl : '/MailManager/ckeditor/uploader?Type=File',
filebrowserImageUploadUrl : '/MailManager/ckeditor/uploader?Type=Image',
filebrowserFlashUploadUrl : '/MailManager/ckeditor/uploader?Type=Flash'
          });
                            </script>

                        <span id="sendTimeTip"></span>
                    </td>
                </tr>

 jsp页面导入：

<%@ taglib uri="http://ckeditor.com" prefix="ckeditor" %>

<script type="text/javascript" src="../javascript/ckeditor/ckeditor.js" charset="UTF-8"></script>

在制作邮件内容时,动态删除了mailContent节点，然后重新生成一个ckeditor编辑器，怎么都生成不出来，后来知道是没有销毁对象的原因，正确的销毁对象：

if(CKEDITOR.instances['content'])//content为代替textarea的id名称
  delete CKEDITOR.instances['content'];
