String formatting is not working in mail sending

问题

  1. String content = 
  2.     "Dear user,\n" +
  3.     "\n" +
  4.     "\t<font face=\"Arial\">Hello</font>\n" +
  5.     "\n" +
  6.     "Regards,\n" +
  7.     "Gen;";
  9. MimeMessage message = emailSender.createMimeMessage();
  10. String encodingOptions = "text/html; charset=UTF-8; format=flowed";
  11. try {
  12.     message.setHeader("Content-Type", encodingOptions);
  13.     message.setSentDate(new Date());
  14.     MimeMessageHelper helper = new MimeMessageHelper(message, true, "utf-8");
  15.     boolean isHTML = true;
  16.     helper.setFrom(mailFrom);
  17.     helper.setTo(to.replaceAll("\\s",""));
  18.     helper.setSubject(subject);
  19.     helper.setText(content, isHTML);
  20. }

接收邮件时，您收到的邮件内容将会是：

  1. Dear user,
  2.     
  3.     Hello
  4.     
  5. Regards,
  6. Gen
英文:

My string is like below

  1. String content  = 
  2. &quot;Dear user,
  4. 	&lt;font face=&quot;Arial&quot;&gt;Hello&lt;/font&gt;
  6. Regards,
  7. Gen&quot;;

I am passing this content to the mail sender.

  1. 	`MimeMessage message = emailSender.createMimeMessage();
  2. 	String encodingOptions = &quot;text/html; charset=UTF-8; format=flowed&quot;;
  3. 	try{
  4. 		message.setHeader(&quot;Content-Type&quot;, encodingOptions);
  5. 		message.setSentDate(new Date());
  6. 		MimeMessageHelper helper = new MimeMessageHelper(message, true, &quot;utf-8&quot;);
  7. 		boolean isHTML = true;
  8. 		helper.setFrom(mailFrom);
  9. 		helper.setTo(to.replaceAll(&quot;\\s&quot;,&quot;&quot;));
  10. 		helper.setSubject(subject);
  11. 		helper.setText(content, isHTML);`

And this content String I am passing to the mail send like above, and it is in the format of html. When I recieve the mail I am getting the mail like below

Dear user,Hello Regards,Gen

How can I display the content in the below format.

  1. Dear user,
  3. 	Hello
  5. Regards,
  6. Gen

因为这是 HTML，你需要自己添加换行。我不是前端开发人员，但你可以使用&lt;p&gt;标签或&lt;br/&gt;标签。

尝试类似这样的代码：

  1. String content = 
  2. &quot;亲爱的用户，&lt;br/&gt;
  4.    &lt;p&gt; &lt;font face=&quot;Arial&quot;&gt;你好&lt;/font&gt;&lt;/p&gt;
  6. 致意，&lt;br/&gt;
  7. Gen&quot;;
英文:

Since it's HTML you have to add the line breaks yourself. I am not a frontend developer but you can use &lt;p&gt; tag or &lt;br/&gt;.
Try something like:

  1. String content  = 
  2. &quot;Dear user, &lt;br/&gt;
  4.    &lt;p&gt; &lt;font face=&quot;Arial&quot;&gt;Hello&lt;/font&gt;&lt;/p&gt;
  6. Regards, &lt;br/&gt;

以下是翻译好的内容：

这条消息正是您创建的内容。简而言之，HTML 不关心空格和换行符。您可以在线测试您的 HTML，看看它的呈现效果，例如在这里：
https://htmledit.squarefree.com/

为了使您的消息格式正确，可以尝试在以下代码行之间插入一些内容：

  1. &lt;html&gt;
  2. &lt;span&gt;亲爱的用户，&lt;/span&gt;&lt;br&gt;&lt;br&gt;
  3. &lt;font face=&quot;Arial&quot;&gt;你好&lt;/font&gt;&lt;br&gt;&lt;br&gt;
  5. &lt;span&gt;祝好，&lt;/span&gt;&lt;br&gt;
  6. &lt;span&gt;Gen&lt;/span&gt;
  7. &lt;/html&gt;

您需要自行添加换行符。您可能可以省略 &lt;span&gt; 标签。

英文:

The message is exactly what you've created. In short HTML doesn't care about spaces and newlines. You can test your HTML online to see how it looks, ie. here:
https://htmledit.squarefree.com/

For your message to be properly formatted, try something between the lines of:

  1. &lt;html&gt;
  2. &lt;span&gt;Dear user,&lt;/span&gt;&lt;/br&gt;&lt;/br&gt;
  3. &lt;span&gt;&lt;font face=&quot;Arial&quot;&gt;Hello&lt;/font&gt;&lt;span&gt;&lt;/br&gt;&lt;/br&gt;
  5. &lt;span&gt;Regards,&lt;/span&gt;&lt;/br&gt;
  6. &lt;span&gt;Gen&lt;/span&gt;
  7. &lt;/html&gt;

You need to provide breaklines yourself. You could probably omit &lt;span&gt; tags.
