# JAVA连接Domino服务器收发邮件代码示例 #

今天在公司整理Domino代码时，顺手写了几个测试代码，晚上回顾时，发现基本涵盖了邮件操作的相关方面，记录之，供以后参考。

依赖JAR包：NCSO.jar

依赖条件：Domino邮件服务器开通DIIOP端口

## 代码示例 ##

代码很简单，直接复制，有不明白的查询相关API即可。

### 收取邮件 ###

@Test public void testReceiveMail()\{ String dominoServer = "192.168.0.252"; String username = "cyy"; Session session = null; Database database = null; View view = null; try \{ session = NotesFactory.createSession(dominoServer, NotesFactory.createORB(), username, "1111"); System.out.println("connect to mail server ok" ); database = session.getDatabase(session.getServerName(), "mail//" + username + ".nsf", false); view = database.getView("($Inbox)"); //获得第一封邮件的unid Document doc = view.getFirstDocument(); String unid = doc.getUniversalID(); //通过具体的unid，获得对应的邮件信息 doc = database.getDocumentByUNID(unid); System.out.println(doc.generateXML()); System.out.println("mail from:" + doc.getItemValueString("Principal")); System.out.println("mail content:" + doc.getItemValueString("Body")); System.out.println("mail subject:" + doc.getItemValueString("Subject")); //处理附件 saveAttachment(doc); \} catch (Exception ex) \{ System.out.println("connect to mail server fail" ); \}finally\{ if(view!=null)\{ try \{ view.recycle(); \} catch (NotesException e) \{ e.printStackTrace(); \} \} if(database!=null)\{ try \{ database.recycle(); \} catch (NotesException e) \{ e.printStackTrace(); \} \} if(session!=null)\{ try \{ session.recycle(); \} catch (NotesException e) \{ e.printStackTrace(); \} \} \} \}

接下来是保存邮件附件到本地的代码：

public void saveAttachment(Document doc) throws NotesException, FileNotFoundException\{ RichTextItem bodyWithAttachs = (RichTextItem) doc.getFirstItem("Body"); if (bodyWithAttachs != null) \{ Vector vAttachs = bodyWithAttachs.getEmbeddedObjects(); Enumeration eAttachs = vAttachs.elements(); while (eAttachs.hasMoreElements()) \{ EmbeddedObject eo = (EmbeddedObject) eAttachs.nextElement(); if (eo.getType() == EmbeddedObject.EMBED\_ATTACHMENT) \{ String storePath = "D:/"; if (!StringUtils.isEmpty(eo.getName())) \{ BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream(storePath + eo.getName(), false)); BufferedInputStream bufferedinputstream = new BufferedInputStream(eo.getInputStream()); int n; try \{ while ((n = bufferedinputstream.read()) != -1) \{ out.write(n); \} out.flush(); out.close(); bufferedinputstream.close(); \} catch (IOException ex1) \{ \} \} \} \} \} \}

### 发送邮件 ###

发送邮件我们分为两类，第一个是不带附件的简单实现，第二个是带多个附件的实现。

#### 不带附件发送邮件 ####

@Test public void testSendMail()\{ String dominoServer = "192.168.0.2"; String username = "cxx"; Session session = null; Database database = null; try \{ //获取session session = NotesFactory.createSession(dominoServer, NotesFactory.createORB(), username, "1111"); System.out.println("connect to mail server ok" ); //得到数据库 database = session.getDatabase(session.getServerName(), "mail//" + username + ".nsf", false); Document doc = database.createDocument(); //设置发件人 doc.appendItemValue("Principal", "cxx@testdomain.com"); //设置主题 doc.appendItemValue("Subject", "我是主题"); //设置收件人 Vector<String> toVect = new Vector<String>(); toVect.add("ggg@testdomain.com"); doc.send(toVect); \} catch (Exception ex) \{ System.out.println("connect to mail server fail" ); \}finally\{ if(database!=null)\{ try \{ database.recycle(); \} catch (NotesException e) \{ e.printStackTrace(); \} \} if(session!=null)\{ try \{ session.recycle(); \} catch (NotesException e) \{ e.printStackTrace(); \} \} \} \}

#### 带多个附件发送邮件 ####

@Test public void testSendMailWithAttachment()\{ String dominoServer = "192.168.0.2"; String username = "cxx"; Session session = null; Database database = null; try \{ //获取session session = NotesFactory.createSession(dominoServer, NotesFactory.createORB(), username, "1111"); System.out.println("connect to mail server ok" ); //得到数据库 database = session.getDatabase(session.getServerName(), "mail//" + username + ".nsf", false); Document doc = database.createDocument(); //设置发件人 doc.appendItemValue("Principal", "cxx@testdomain.com"); //设置主题 doc.appendItemValue("Subject", "我是主题"); //设置收件人 Vector<String> toVect = new Vector<String>(); toVect.add("ggg@testdomain.com"); doc.appendItemValue("Form", "Memo"); RichTextItem rti = doc.createRichTextItem("Body"); rti.addNewLine(2); rti.embedObject(EmbeddedObject.EMBED\_ATTACHMENT, null, "D:/test.png", "D:/test.png"); rti.addNewLine(2); rti.embedObject(EmbeddedObject.EMBED\_ATTACHMENT, null, "D:/test.txt", "D:/test.txt"); //开始发送 doc.send(true,toVect); \} catch (Exception ex) \{ System.out.println("connect to mail server fail" ); \}finally\{ if(database!=null)\{ try \{ database.recycle(); \} catch (NotesException e) \{ e.printStackTrace(); \} \} if(session!=null)\{ try \{ session.recycle(); \} catch (NotesException e) \{ e.printStackTrace(); \} \} \} \}

至于复杂的操作，基本都可以从如上代码中类推出来，或者百度、google一下。
