关于使用javamail包发送邮件和邮件编码乱码解决方法
1. 在发送正文时指定正文编码：
在发送邮件时使用
MimeBodyPart body = new MimeBodyPart();
body.setContent(content, "text/html;charset=GB2312");
注意此时的content编码必须是所指定的编码格式。
2. 在设置邮件标题时也要指定标题的编码：
MimeMultipart mmp=new MimeMultipart();
mmp.setSubject(subject, "GB2312");
同上也要求subject的编码和指定的编码一致。
3. 发送正文时也可以在header中指定传输编码：
body.setHeader("Content-Transfer-Encoding", "base64"); // 指定使用base64编码
4. 例子：
[java] view
