javamail发送邮件

需要在邮件发送html表格，看到这篇文章（https://blog.csdn.net/mobile18611667978/article/details/70169338）。设置text/html即可  testMessage.setContent(messageText, "text/html;charset=gb2312");

                                    String from, String to,

                                    String subject, String messageText)

             throws MessagingException,java.io.UnsupportedEncodingException {

  

         // Step 1:  Configure the mail session

         System.out.println("Configuring mail session for: " + smtpHost);

         java.util.Properties props = new java.util.Properties();

         String to = "mfc42d@sohu.com";

         String subject = "html邮件测试"; //subject javamail自动转码

         theMessage.append("<h2><font color=red>这倒霉孩子</font></h2>");

         theMessage.append("<hr>");

         theMessage.append("<i>年年失望年年望</i>");
