* Chinese Characters in html and English name of attachments are garbled.
* Some Chinese garbled characters need to be fixed during use!
1. Add verification; otherwise, an error message of 553 authentication is required will be reported.
Properties prop = new Properties ();
Prop. setProperty ("mail. smtp. auth", "true ");
JavaMailSenderImpl. setJavaMailProperties (prop );
2. Chinese when the email content is in HTML:
When initializing the MimeMessageHelper helper class, set "GBK" encoding! For example:
MimeMessageHelper messageHelp = new MimeMessageHelper (message, true, "GBK ");
At the same time, set <META http-equiv = Content-Type content = 'text/html; charset = gbk'>
If both are set to "UTF-8", the title of some mail clients cannot be displayed normally!
3. A Chinese Question about the email attachment!
In the spring document, it is said that MimeMessageHelper has set encoding and has a function on title, text, and attach, but problems still occur:
Solution: MimeUtility. encodeWord (file. getName (); OK!
