EMail

1. 添加中文名附件（使用库：email，如果没有源码可参考GitHub上）

        MimeBodyPart.setFileName(filename);

        直接使用有可能中文乱码可以使用如下的方法

• MimeBodyPart.setFileName(MimeUtility.encodeWord(fileName));

                使用这个可以实现中文的显示（客户端和服务器端都可以）

                可以查看RFC2047文件了解encodeWord详情。下面部分原文信息……

                Generally, an "encoded-word" is a sequence of printable ASCII

                characters that begins with "=?", ends with "?=", and has two "?"s in

                between. It specifies a character set and an encoding method, and

                also includes the original text encoded as graphic ASCII characters,

                according to the rules for that encoding method.

                A mail composer that implements this specification will provide a

                means of inputting non-ASCII text in header fields, but will

                translate these fields (or appropriate portions of these fields) into

                encoded-words before inserting them into the message header.

• MimeBodyPart.setFileName(new String(fileName.getBytes(), "ISO-8859-1"));

                使用这个可以，客户端可以显示，服务端显示异常。（“复制”到服务器端显示为“澶嶅埗”）。
