1、发送简单文本邮件

Email email = new SimpleEmail();
email.setHostName("smtp.googlemail.com");
email.setSmtpPort(465);
email.setAuthenticator(new DefaultAuthenticator("username", "password"));
email.setSSLOnConnect(true);
email.setFrom("[email protected]");
email.setSubject("TestMail");
email.setMsg("This is a test mail ... :-)");
email.addTo("[email protected]");
email.send();

2、发送带附件的邮件

// Create the attachment
  EmailAttachment attachment = new EmailAttachment();
  attachment.setPath("mypictures/john.jpg");
  attachment.setDisposition(EmailAttachment.ATTACHMENT);
  attachment.setDescription("Picture of John");
  attachment.setName("John");

  // Create the email message
  MultiPartEmail email = new MultiPartEmail();
  email.setHostName("mail.myserver.com");
  email.addTo("[email protected]", "John Doe");
  email.setFrom("[email protected]", "Me");
  email.setSubject("The picture");
  email.setMsg("Here is the picture you wanted");

  // add the attachment
  email.attach(attachment);

  // send the email
  email.send();

另外还可以通过任意的链接来将网络上的文件添加到附件中，例如：

// Create the attachment
  EmailAttachment attachment = new EmailAttachment();
  attachment.setURL(new URL("http://www.apache.org/images/asf_logo_wide.gif"));
  attachment.setDisposition(EmailAttachment.ATTACHMENT);
  attachment.setDescription("Apache logo");
  attachment.setName("Apache logo");

  // Create the email message
  MultiPartEmail email = new MultiPartEmail();
  email.setHostName("mail.myserver.com");
  email.addTo("[email protected]", "John Doe");
  email.setFrom("[email protected]", "Me");
  email.setSubject("The logo");
  email.setMsg("Here is Apache's logo");
  
  // add the attachment
  email.attach(attachment);

  // send the email
  email.send();

3、发送HTML格式的邮件

// Create the email message
  HtmlEmail email = new HtmlEmail();
  email.setHostName("mail.myserver.com");
  email.addTo("[email protected]", "John Doe");
  email.setFrom("[email protected]", "Me");
  email.setSubject("Test email with inline image");
  
  // embed the image and get the content id
  URL url = new URL("http://www.apache.org/images/asf_logo_wide.gif");
  String cid = email.embed(url, "Apache logo");
  
  // set the html message
  email.setHtmlMsg("The apache logo - ");

  // set the alternative message
  email.setTextMsg("Your email client does not support HTML messages");

  // send the email
  email.send();

4、发送带图片的HTML格式邮件

// load your HTML email template
  String htmlEmailTemplate = ....

  // define you base URL to resolve relative resource locations
  URL url = new URL("http://www.apache.org");

  // create the email message
  HtmlEmail email = new ImageHtmlEmail();
  email.setDataSourceResolver(new DataSourceResolverImpl(url));
  email.setHostName("mail.myserver.com");
  email.addTo("[email protected]", "John Doe");
  email.setFrom("[email protected]", "Me");
  email.setSubject("Test email with inline image");
  
  // set the html message
  email.setHtmlMsg(htmlEmailTemplate);

  // set the alternative message
  email.setTextMsg("Your email client does not support HTML messages");

  // send the email
  email.send();

另外，在使用过程中发现Email.addTo一次只能添加一个联系人，如果想发送给多个人的话，需要使用for循环嵌套来实现，以下是一个简单的例子：

public static void main(String[] args){

        String mailList = "[email protected];[email protected]";

        String[] list = mailList.split(";");
        for(int i=0;list!=null && i
