JavaMail the solution of the topic garbled in sending mail

Send a message | To solve many friends have used JavaMail to send mail, in the message body garbled easily resolved. But the message theme garbled no matter how the transcoding always shows a pile of garbled. What should I do with it?

The message subject in JavaMail needs to be BASE64 encoded, in the form of:
=? GB2312? b?xpq1xmpcwuvs0b6t1tjww6osx+u+ob/stcfcvkossqlq3rjew9zc66oh?=
Therefore, the direct use of Msg.setsubject ("Chinese theme"), or Msg.setsubject ("Chinese theme". GetBytes ("8859_1"), "GB2312") will appear garbled. You need to encode the byte of the subject string into the BASE64 format before you set the message subject, and add the encoding header, as shown in the sample code:


Sun.misc.BASE64Encoder enc = new Sun.misc.BASE64Encoder (); Msg.setsubject ("=? GB2312? B? " +enc.encode (Subject.getbytes ()) + "? =");
