java - 井号在使用 java.mail 包的邮件内容中不起作用？

Question

大家好，

我正在使用 javax.mail 包 MINEMESSAGE,MimeMultipart 类发送邮件，但即使我提到类型 utf-8，unicode 字符在正文中也不起作用。就像英镑符号不起作用一样。请帮忙该怎么办。这是我的消息标题

这是代码

Answer 1

两种可能性。

首先，您确定 emsg.content 包含未修改的数据吗？如果在你看到这段代码之前它就已经损坏了，那么你就运气不好了。

其次，如果内容没问题，请尝试使用MimeBodyPart.setText():

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