JSP开发全程实录第四章企业快信添加一般信息和发邮件出去（或带附件的附件名是中文）只要出现中文就乱啊？
且当发邮件时带附件的附件名是中文时邮件发送就失败。

在设置邮件主题前需要将主题字串的字节编码为BASE64格式，并添加编码头，示例代码如下：
try{
String subject = "中华全国helloworld";
String content = "测试邮件中语言问题.helloworld";
Context ctx = new InitialContext();
if(ctx == null)
throw new Exception("NO Context()");
System.out.println(ctx);

javax.mail.Session mailsession = (javax.mail.Session)ctx.lookup("java:comp/env/mail/session");
System.out.println(mailsession);

Message msg = new MimeMessage(mailsession);

InternetAddress[] toAddrs = InternetAddress.parse("david.li@maxcard.com",false);
msg.setRecipients(Message.RecipientType.TO, toAddrs);
//msg.setSubject("=?GB2312?B?"+Base64.encode(subject.getBytes())+"?=");

//将中文转化为GB2312编码
subject = StringUtil.getString(subject, "GB2312");
subject = new String(Base64.encode((subject).getBytes()));
msg.setSubject("=?GB2312?B?" + subject + "?=");

msg.setFrom(new InternetAddress("david.li@maxcard.com"));
msg.setText(StringUtil.getString(content,"GB2312"));
//
Transport t = mailsession.getTransport("smtp");
t.send(msg);
out.println("成功");
//Transport.send(msg);
}catch(Exception e){
out.println("失败");
System.out.println(e);
}
