Question

全部，

我正在使用javax.mail packaage MINEMESSAGE，MimeMultipart类发送邮件，但即使我提到类型为utf-8，unicode字符也无法在正文中使用。像英镑标志不起作用。请帮忙做什么。这是我的邮件标题

以下是代码

MimeMessage msg = new MimeMessage(session);

        InternetAddress addressTo[] = new InternetAddress[emsg.getRecipeants()
                .size()];
        int i = 0;
        try {
            for (String email : emsg.getRecipeants()) {
                InternetAddress address = new InternetAddress(email);
                addressTo[i] = address;
                log.info(acc.getSenderEmailID() + " sending mail To " + email);
            }

            msg.setRecipients(Message.RecipientType.TO, addressTo);
            if (emsg.getReplayTO() != null) {
                msg.setReplyTo(new InternetAddress[] { new InternetAddress(emsg
                        .getReplayTO()) });
            }
            String from = "";
            if (!acc.getAccoutName().equals("")) {
                from = acc.getAccoutName() + "<" + acc.getSenderEmailID() + ">";
            } else {
                from = acc.getSenderEmailID();
            }
            msg.setFrom(new InternetAddress(from));
            // MultiPart body part

            Multipart multipart = new MimeMultipart();

            // This is the message body content part

            MimeBodyPart messageContentPart = new MimeBodyPart();

            String content = processContent(emsg.content, multipart,
                    comapanyDBName);
            if (emsg.isPlain) {
                messageContentPart.setContent(content,
                        "text/plain; charset=UTF-8");

                    messageAttachmentBodyPart = new MimeBodyPart();

                    DataSource source = new FileDataSource(file);

            // Put parts in message
            msg.setContent(multipart);

            // end

            // Optional : You can also set your custom headers in the Email

Answer 1

两种可能性。

首先，您确定emsg.content包含非广域数据吗？如果它在您使用此代码之前已损坏，那么您已经不幸了。

其次，如果content没问题，请尝试使用MimeBodyPart.setText()：

        if (emsg.isPlain) {
            messageContentPart.setText(content, "UTF-8", "plain");
        } else {
            messageContentPart.setText(content, "UTF-8", "html");
        }

Answer 2

我认为虽然你设置的内容类型字符集UTF-8你不写UTF8流。你在使用BufferedWriter吗？检查是否将正确的charset传递给其构造函数。

磅标志使用java.mail包在邮件内容中不起作用？
