本文整理了Java中javax.mail.Multipart类的一些代码示例，展示了Multipart类的具体用法。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。Multipart类的具体详情如下：
包路径：javax.mail.Multipart
类名称：Multipart

Multipart介绍

[英]Multipart is a container that holds multiple body parts. Multipart provides methods to retrieve and set its subparts.

Multipart also acts as the base class for the content object returned by most Multipart DataContentHandlers. For example, invoking getContent() on a DataHandler whose source is a "multipart/signed" data source may return an appropriate subclass of Multipart.

Some messaging systems provide different subtypes of Multiparts. For example, MIME specifies a set of subtypes that include "alternative", "mixed", "related", "parallel", "signed", etc.

Multipart is an abstract class. Subclasses provide actual implementations.
[中]Multipart是一个容纳多个身体部位的容器。Multipart提供了检索和设置其子部分的方法。
Multipart还充当大多数多部分DataContentHandler返回的内容对象的基类。例如，在源为“多部分/签名”数据源的DataHandler上调用getContent（）可能会返回相应的多部分子类。
一些消息传递系统提供不同的多部分子类型。例如，MIME指定了一组子类型，包括“alternative”、“mixed”、“related”、“parallel”、“signed”等。
Multipart是一个抽象类。子类提供了实际的实现。

Multipart multipart = new MimeMultipart("mixed");
for (String str : attachment_PathList) {
  MimeBodyPart messageBodyPart = new MimeBodyPart();
  DataSource source = new FileDataSource(str);
  messageBodyPart.setDataHandler(new DataHandler(source));
  messageBodyPart.setFileName(source.getName());
  multipart.addBodyPart(messageBodyPart);
}
msg.setContent(multipart);
Transport.send(msg);

 */

  final int count = mp.getCount();
  for (int i = 0; i < count; i++) {
    final Part innerPart = mp.getBodyPart(i);
