java - 通过java邮件发送消息

Question

您好，我可以从我的网络应用程序发送邮件。但这里的问题是我只能发送一行消息，即

我想发送一条消息:

您的用户名是:xxxx 您的密码是:xxx

     Message message = new MimeMessage(session);
                    message.setFrom(new InternetAddress("<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="245c5c5c644349454d480a474b49" rel="noreferrer noopener nofollow">[email protected]</a>"));
                    message.setRecipients(Message.RecipientType.TO,
                        InternetAddress.parse(Class.email));
                    message.setSubject("Registration Confirmation with SK Business Group");
                    message.setContent("<h1>Congratulations on successfully registering with us</h1><h2>Your user name is:</h2>" +Class.uname ,  
                            "text/html");
message.setContent("<h2>Your password is:</h2>" +Class.pass ,  
                            "text/html");

                    Transport.send(message);

但是当邮件到达收件人时，仅显示用户名...

我希望同时显示用户名和密码。请有人帮我解决这个问题..先谢谢了。

注意: uname和pass是类的静态变量，通过类名获取。

您要设置内容两次，请在对 setContent 的同一调用中添加这两行:

message.setContent("<h1>Congratulations on successfully registering with us</h1>"
    + "<h2>Your user name is:</h2>" +ApproveDAO.uname
    + "<h2>Your password is:</h2>" +ApproveDAO.pass, "text/html");
