下面是一個例子，從你的機器發送HTML格式電子郵件。這里通過使用JangoSMPT服務器的郵件發送到我們的目標電子郵件地址。

這個例子非常相似，發送簡單的電子郵件，除非，這里我們使用的是使用setContent()方法來設置內容的第二個參數為“"text/html"指定的HTML內容被包含在消息中。通過這個例子，你可以發送喜歡HTML內容。

發送包含HTML內容的電子郵件，遵循的步驟是：

獲得一個Session

創建一個默認的MimeMessage對象，并設置發件人，收件人，主題(From,?To,?Subject)在消息中。

設置使用使用setContent(實際的消息)，如下方法：

message.setContent("

This is actual message embedded in

HTML tags","text/html");

發送使用傳輸對象的消息。

創建Java類

創建一個Java類文件SendHTMLEmail，是其內容如下：

packagecom.yiibai;importjava.util.Properties;importjavax.mail.Message;importjavax.mail.MessagingException;importjavax.mail.PasswordAuthentication;importjavax.mail.Session;importjavax.mail.Transport;importjavax.mail.internet.InternetAddress;importjavax.mail.internet.MimeMessage;publicclassSendHTMLEmail{publicstaticvoidmain(String[]args){// Recipient's email ID needs to be mentioned.Stringto="destinationemail@gmail.com";// Sender's email ID needs to be mentionedStringfrom="fromemail@gmail.com";finalStringusername="manishaspatil";//change accordinglyfinalStringpassword="******";//change accordingly// Assuming you are sending email through relay.jangosmtp.netStringhost="relay.jangosmtp.net";Propertiesprops=newProperties();props.put("mail.smtp.auth","true");props.put("mail.smtp.starttls.enable","true");props.put("mail.smtp.host",host);props.put("mail.smtp.port","25");// Get the Session object.Sessionsession=Session.getInstance(props,newjavax.mail.Authenticator(){protectedPasswordAuthenticationgetPasswordAuthentication(){returnnewPasswordAuthentication(username,password);}});try{// Create a default MimeMessage object.Messagemessage=newMimeMessage(session);// Set From: header field of the header.message.setFrom(newInternetAddress(from));// Set To: header field of the header.message.setRecipients(Message.RecipientType.TO,InternetAddress.parse(to));// Set Subject: header fieldmessage.setSubject("Testing Subject");// Send the actual HTML message, as big as you likemessage.setContent("

This is actual message embedded in HTML tags

","text/html");// Send messageTransport.send(message);System.out.println("Sent message successfully....");}catch(MessagingExceptione){e.printStackTrace();thrownewRuntimeException(e);}}}

由于我們使用的是由主機提供商JangoSMTP提供 SMTP服務器，我們需要驗證用戶名和密碼。javax.mail.PasswordAuthentication類用于驗證的密碼。

編譯并運行

Now that our class is ready, let us compile the above class. I've saved the class SendHTMLEmail.java to directory :?/home/manisha/JavaMailAPIExercise. We would need the jars?javax.mail.jar?andactivation.jar?in the classpath. Execute the command below to compile the class (both the jars are placed in /home/manisha/ directory) from command prompt:

javac-cp/home/manisha/activation.jar:/home/manisha/javax.mail.jar:SendHTMLEmail.java

Now that the class is compiled, execute the below command to run:

java-cp/home/manisha/activation.jar:/home/manisha/javax.mail.jar:SendHTMLEmail

Verify Output

You should see the following message on the command console:

Sentmessage successfully....

As I'm sending an email to my gmail address through JangoSMTP, the following mail would be received in my gmail account inbox:
