本文整理了Java中javax.mail.internet.MimeMessage.updateHeaders()方法的一些代码示例，展示了MimeMessage.updateHeaders()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。MimeMessage.updateHeaders()方法的具体详情如下：
包路径：javax.mail.internet.MimeMessage
类名称：MimeMessage
方法名：updateHeaders
[英]Called by the saveChanges method to actually update the MIME headers. The implementation here sets the Content-Transfer-Encoding header (if needed and not already set), the Date header (if not already set), the MIME-Version header and the Message-ID header. Also, if the content of this message is a MimeMultipart, its updateHeaders method is called.
If the #cachedContent field is not null (that is, it references a Multipart or Message object), then that object is used to set a new DataHandler, any stream data used to create this object is discarded, and the #cachedContent field is cleared.
[中]由saveChanges方法调用以实际更新MIME头。此处的实现设置Content-Transfer-Encoding头（如果需要且尚未设置），Date头（如果尚未设置），MIME-Version头和Message-ID头。此外，如果此消息的内容是MimeMultipart，则会调用其updateHeaders方法。
如果#cachedContent字段不为null（即，它引用多部分或消息对象），则该对象用于设置新的DataHandler，用于创建此对象的任何流数据都将被丢弃，#cachedContent字段将被清除。
