本文整理了Java中javax.mail.internet.MimeBodyPart.setFileName()方法的一些代码示例，展示了MimeBodyPart.setFileName()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。MimeBodyPart.setFileName()方法的具体详情如下：
包路径：javax.mail.internet.MimeBodyPart
类名称：MimeBodyPart
方法名：setFileName

MimeBodyPart.setFileName介绍

[英]Set the filename associated with this body part, if possible.

Sets the "filename" parameter of the "Content-Disposition" header field of this body part. For compatibility with older mailers, the "name" parameter of the "Content-Type" header is also set.

If the mail.mime.encodefilename System property is set to true, the MimeUtility#encodeText method will be used to encode the filename. While such encoding is not supported by the MIME spec, many mailers use this technique to support non-ASCII characters in filenames. The default value of this property is false.
[中]如果可能，设置与此身体部位关联的文件名。
设置此正文部分的“内容处置”标题字段的“文件名”参数。为了与旧邮件程序兼容，还设置了“内容类型”标题的“名称”参数。
如果mail.mime.encodefilename系统属性设置为true，则将使用MimeUtility#encodeText方法对文件名进行编码。虽然MIME规范不支持这种编码，但许多邮件程序使用这种技术来支持文件名中的非ASCII字符。此属性的默认值为false。
