得到用户收件箱中的邮件

三个知识点：

1：如果是打开mailfile数据库后直接

Database dbMail = sNotes.getDatabase(sNotes.getServerName(),

                      mailfile, false);

DocumentCollection dc = dbMail.getAllDocuments();

Document doc = dc.getFirstDocument();

这样打开的是用户邮箱数据库中全部邮件。

如果是选择了$Inbox视图，才会只浏览收件箱中的所有邮件，如下面的代码所示。

2：程序模拟用户身份访问邮箱，其中的所有邮件都会是新邮件，除非自己做标记。

3：关于邮件的日期，最好“delivereddate”和“posteddate”两个字段都取出来，这样保险。

代码片段：

Database dbMail = sNotes.getDatabase(sNotes.getServerName(),                       mailfile, false); if(dbMail == null)     {               System.out.println("cannot open database " + mailfile);     }     else     {            // 如果按照下面的dc.getFirstDocument，可能连垃圾箱中的未读邮件都取出来了            View viewInbox = dbMail.getView("($Inbox)");            // 所以我们得到Inbox视图,这样只读取收件箱中的邮件            Document doc = viewInbox.getFirstDocument();                // 此处的新邮件数量，并不是用户自身Notes看到的新邮件数量，因为身份不同；     // 当我们的程序第一次访问用户邮箱，所有的邮件将都是新邮件 //Document doc = dc.getFirstDocument();   while (doc != null) {            /** 添加新邮件项的节点 */            Element mailElement = mailsElement.addElement("mail");                      // 发件人            Element fromE = mailElement.addElement("from");            fromE.addCDATA(doc.getItemValueString("Principal"));            // 收件日期            Element dateE = mailElement.addElement("date");            Item deliveredDate = doc.getFirstItem( "delivereddate" ) ;            Item     postedDate    = doc.getFirstItem( "posteddate" ) ;            String   timestamp     = new String( "" ) ;            if ( deliveredDate != null )                timestamp = deliveredDate.getText() ;             else if ( postedDate != null )                timestamp = postedDate.getText() ;            // 发送日期和接收日期，我们都要进行读取，发送日期是优先的            dateE.addCDATA(timestamp);            // 主题            Element subjectE = mailElement.addElement("subject");            subjectE.addCDATA(doc.getItemValueString("Subject"));            // NoteID            Element NoteIDE = mailElement.addElement("NoteID");            NoteIDE.setText(doc.getNoteID());            // UniversalID            Element UniversalIDE = mailElement.addElement("UniversalID");            UniversalIDE.setText(doc.getUniversalID());                       String strBody = "";            if(doc.getItemValueString("Body") != null)                {                   strBody = doc.getItemValueString("Body");                   if(strBody.length() > 12)                  {                          strBody = strBody.substring(12) + "...";                  }                }                else                {                       strBody = "没有正文";                } }

。

取到邮件的附件集合

 

代码片段：

try                           {                                  // grab the Body field of the current document,                                     // and check each attachment                                  RichTextItem bodyWithAttachs =                                         (RichTextItem)doc.getFirstItem("Body");                                  System.out.println("-= begin getFirstItem =-");                                  // 查看附件                                  if(bodyWithAttachs != null)                                  {                                                                          System.out.println("-= get RichTextItem =-");                                                                                  Vector vAttachs = bodyWithAttachs.getEmbeddedObjects();                                         System.out.println("-= get Vector =-");                                         Enumeration eAttachs = vAttachs.elements();                                         System.out.println("-= get Enumeration =-");                                                                                 // 读取共有多少个附件                                         Element attachmentsE = mailElement.addElement("attachments");                                         Element countE = attachmentsE.addElement("count");                                         countE.setText(String.valueOf(vAttachs.size()));                                           while (eAttachs.hasMoreElements())                                         {                                                EmbeddedObject eo = (EmbeddedObject)eAttachs.nextElement();                                                if (eo.getType() == EmbeddedObject.EMBED_ATTACHMENT)                                                {                                                 // 添加附件名称的节点                                                    Element attachE = attachmentsE.addElement("attachment");                                                    attachE.setText(eo.getSource());                                                }                                                eo.recycle();                                         }                                  }                              }                           catch(Exception e)                                {                                       if(e instanceof lotus.domino.NotesException)                                       {                                              System.out.println(                                                            "访问邮件的附件时发生错误，错误代码为"                                                      +((lotus.domino.NotesException)e).id);                                       }                                    e.printStackTrace();                                    System.out.println(e.getLocalizedMessage());                                }
