在java中用日语字符发送电子邮件 [英] Email with japanese characters in java

问题描述

我正在使用java发送电子邮件。发送的消息可以使用不同的语言，但是当我用日语发送时，收到的邮件只有???????字符。

I am using java to send emails. The message sent can be in different languages, but when I send it in Japanese, the received mail just have "???????" characters.

代码是这样的：

 String content = "\u30d5\u30a1\u30a4\u30eb\u540d:";    
SMTPMessage message = new SMTPMessage(sess);
            message.setFrom(new InternetAddress(from));
            InternetAddress dests[] = new InternetAddress[]{ new InternetAddress(to) };
            message.setRecipients(Message.RecipientType.TO, dests);
            message.setSubject(subject);
            message.setContent(content, "text/html");

            Transport.send(message);

发送的内容是unicode字符。我应该如何正确编码消息？

The content sent are unicode characters. How should I encode correctly the message?

推荐答案

你应该使用 setText 代替 setContent

message.setText( content, "UTF-8", "html" );
