我正在寻找保存包含内联图像和 HTML 内容的电子邮件正文的最佳方式。我想保留邮件包含的所有内容。
我的最终目标是将完整的电子邮件正文保存为 PDF
如果有将电子邮件正文写入 PDF 的直接方法?
如果不是,保存电子邮件的最佳格式是什么?
我可以使用其他一些可用的 API 将 HTML、DOC 等转换为 PDF。
private void downloadAttachment(Part part, String folderPath) throws Exception {
String disPosition = part.getDisposition();
String fileName = part.getFileName();
String decodedText = null;
logger.info("Disposition type :: " + disPosition);
logger.info("Attached File Name :: " + fileName);
if (disPosition != null && disPosition.equalsIgnoreCase(Part.ATTACHMENT)) {
logger.info("DisPosition is ATTACHMENT type.");
File file = new File(folderPath + File.separator + decodedText);
file.getParentFile().mkdirs();
saveEmailAttachment(file, part);
} else if (fileName != null && disPosition == null) {
logger.info("DisPosition is Null type but file name is valid. Possibly inline attchment");
File file = new File(folderPath + File.separator + decodedText);
file.getParentFile().mkdirs();
saveEmailAttachment(file, part);
} else if (fileName == null && disPosition == null) {
logger.info("DisPosition is Null type but file name is null. It is email body.");
File file = new File(folderPath + File.separator + "mail.html");
file.getParentFile().mkdirs();
saveEmailAttachment(file, part);
}
}
protected int saveEmailAttachment(File saveFile, Part part) throws Exception {
BufferedOutputStream bos = null;
InputStream is = null;
int ret = 0, count = 0;
try {
bos = new BufferedOutputStream(new FileOutputStream(saveFile));
part.writeTo(new FileOutputStream(saveFile));
} finally {
try {
if (bos != null) {
bos.close();
}
if (is != null) {
is.close();
}
} catch (IOException ioe) {
logger.error("Error while closing the stream.", ioe);
}
}
return count;
}
请建议。谢谢!
