好吧,我通过检查 any 的类解决了MimePart,我发现嵌套消息的类型是IMAPNestedMessage,所以在这种对象上我递归调用 main 方法processMessage:
private void processAttachment(final Multipart multipart) {
try {
for (int i = 0; i < multipart.getCount(); i++) {
final BodyPart bodyPart = multipart.getBodyPart(i);
// BEGIN - Added this part
System.out.println("CLASS bodyPart: " + bodyPart.getContent().getClass());
if (bodyPart.getContent() instanceof IMAPNestedMessage) {
processMessage((IMAPNestedMessage) bodyPart.getContent());
} else {
// END - Added this part
if (bodyPart.getContent() instanceof Multipart) {
processAttachment((Multipart) bodyPart.getContent());
} else {
final boolean isXml = bodyPart.getFileName() != null && isXmlType(bodyPart.getContentType());
if (isXml) {
final InputStream inputStream = getReusableInputStream(bodyPart);
processXMLAttachment(inputStream);
}
}
}
}
} catch (final Exception e) {
sendMailService.sendMailForImportINPSFailed("metodo processAttachment()", e);
e.printStackTrace();
}
}
现在它工作正常。
