下面是一个例子，从你的机器发送HTML格式电子邮件。这里通过使用JangoSMPT服务器的邮件发送到我们的目标电子邮件地址。
这个例子非常相似，发送简单的电子邮件，除非，这里我们使用的是使用setContent()方法来设置内容的第二个参数为“"text/html"指定的HTML内容被包含在消息中。通过这个例子，你可以发送喜欢HTML内容。
发送包含HTML内容的电子邮件，遵循的步骤是：
获得一个Session
创建一个默认的MimeMessage对象，并设置发件人，收件人，主题(From,To,Subject)在消息中。
设置使用使用setContent(实际的消息)，如下方法：
message.setContent("
This is actual message embedded in
HTML tags","text/html");
发送使用传输对象的消息。
创建Java类
创建一个Java类文件SendHTMLEmail，是其内容如下：
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@";// Sender's email ID needs to be mentionedStringfrom="fromemail@";finalStringusername="manishaspatil";//change accordinglyfinalStringpassword="******";//change accordingly// Assuming you are sending email through Stringhost="";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);}}}由于我们使用的是由主机提供商JangoSMTP提供 SMTP服务器，我们需要验证用户名和密码。javax.mail.PasswordAuthentication类用于验证的密码。
编译并运行
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 jarsjavax.mail.jarandactivation.jarin 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:
