Just type the tags into your message like String msg = "<strong>Hello World!</strong>and send it as a HTML message, you only need to set type of the content via MimeMessage#setContent()method like
只需在您的消息中键入标签String msg = "<strong>Hello World!</strong>并将其作为 HTML 消息发送，您只需要通过MimeMessage#setContent()类似的方法设置内容的类型
message.setContent(msg, "text/html; charset=utf-8");`

If you want to do it the old school, vanilla java way you can use the org.w3c.dom.DocumentAPI to get the work done.
如果你想用老式的、vanilla java 的方式来做，你可以使用org.w3c.dom.DocumentAPI 来完成工作。
It has a bunch of useful methods for creating and manipulating elements such as createElement, createAttribute, etc. to do what you want.
它用于创建和操作元件，如一堆有用的方法createElement，createAttribute等等。做你想做什么。

As per the Javadoc, the MimeMessage#setText()sets a default mime type of text/plain, while you need text/html. Rather use MimeMessage#setContent()instead.
根据Javadoc，MimeMessage#setText()设置默认的 MIME 类型text/plain，而您需要 text/html。而是使用MimeMessage#setContent()代替。
String someHtmlMessage = "Hello this is test message <b style='color:blue;'>bold color</b>";
message.setContent(someHtmlMessage, "text/html; charset=utf-8");
Note that the HTML should not contain the <html>, <head> or <body>. Gmail will ignore it. See also CSS support in mail clients.
请注意，HTML 不应包含<html>, <head> or <body>. Gmail 会忽略它。另请参阅邮件客户端中的 CSS 支持。
