JAVA连接Domino服务器收发邮件代码示例

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

@Testpublic 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unidDocument 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

@Testpublic void testSendMail(){String dominoServer = “192.168.0.2”;String username = “cxx”;Session session = null;Database database = null;try {//获取sessionsession = 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

@Testpublic void testSendMailWithAttachment(){String dominoServer = “192.168.0.2”;String username = “cxx”;Session session = null;Database database = null;try {//获取sessionsession = 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。
