                     // user name, password 
                    String props.getProperty the userName = ( "the mail.user" ); 
                    String password = props.getProperty ( "mail.password" );
                     return  new new PasswordAuthentication (the userName, password);
                }
            };
            // environment attribute and authorization information, create a mail session 
            the Session mailSession = Session.getInstance (props, Authenticator);
             // create a mail message 
            the MimeMessage the Message = new new the MimeMessage (mailSession);
             // set the sender 
            InternetAddress form = new new InternetAddress ( props.getProperty ( "mail.user" )); 
            message.setFrom (form); 
 
            // set the recipient's mailbox 
            InternetAddress to = new new InternetAddress ( "the recipient's mailbox qq.com @" ); 
            message.setRecipient (RecipientType .TO, to); 
 
            // set the message subject 
            message.setSubject ( "test Mail");
             // setup message date 
            message.setSentDate ( new new a Date ()); 
            
            // HTML file 
            the StringBuilder SB = new new the StringBuilder (); 
            sb.append ( "<h1 of> text </ h1 of>" );        
             // Set the message the content body 
            message.setContent (sb.toString (), "text / HTML; charset = UTF-8" ); 
 
            // Finally, of course, is to send a message 
            Transport.send (the message); 
            System.out.println ( "successfully sent! " ); 
        } the catch (E, AddressException) { 
            System.out.println ( " transmission failed "+! e.getMessage ());
            e.printStackTrace();
        } catch (MessagingException e) {
            System.out.println("发送失败！"+e.getMessage());
            e.printStackTrace();
        }
    }
