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

        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();

        alternativeMulti.addBodyPart(textBody);
        alternativeBodyPart.setContent(alternativeMulti);
        relatedMulti.addBodyPart(alternativeBodyPart);
        
         //  内置资源部分
         int  i  =   0 ;
         for  (String imgFileName : imgFileNames) {

            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

        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 " ;

            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));
            message.setFrom( new  InternetAddress(from));
    
             //  发送开始

            transport.connect((String) props.get( " mail.smtp.host " ),
            EMAIL_NAME, EMAIL_PASSWORD);
    
            transport.sendMessage(message,
            message.getRecipients(Message.RecipientType.TO));
            transport.close();

        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" %>

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 ' ];
