private String getAttachments（消息消息，HttpServletRequest请求）throws MessagingException，IOException {
String contentType = message.getContentType（）;
String attachFiles =;
if（contentType.contains（multipart））{
//内容可能包含附件
Multipart multiPart =（Multipart）message.getContent（）;
int numberOfParts = multiPart.getCount（）;
for（int partCount = 0; partCount< numberOfParts; partCount ++）{
MimeBodyPart part =（MimeBodyPart）multiPart.getBodyPart（partCount）;
String disposition = part.getDisposition（）;
String file = part.getFileName（）;
//外部附件
if（disposition！= null&&&& Part.ATTACHMENT.equalsIgnoreCase（disposition））{
//这部分是附件
String fileName = new Date（）。getTime（）+_+ part.getFileName（）。replaceAll（[^ a-zA-Z0-9\\ ._] +，_）; //要使附件名称为uniq，我们在名称之前添加当前的datatime。
attachFiles + = fileName +，; //具体所有附件的名称用逗号分隔。
part.saveFile（new File（request
.getSession（）
.getServletContext（）
.getRealPath（
/ WEB-INF / attechments /
+ fileName）））; //将附件文件保存在特定位置。
// LOG.info（\\\
\t Path： - + request.getSession（）。getServletContext（）。getRealPath（/ WEB-INF / attechments /+ fileName））;
}
//内联附件
else if（disposition！= null&&&&PartitionIn.ELINE.equalsIgnoreCase（disposition））{
//这部分是附件
String fileName = new Date（）。getTime（）+_+ part.getFileName（）。replaceAll（[^ a-zA-Z0-9\\ ._] +，_） ; //要使附件名称为uniq，我们在名称之前添加当前的datatime。

}
//内联图标和笑脸
else if（file！= null&& disposition == null）
{
String fileName = new Date ）.getTime（）+_+ part.getFileName（）。replaceAll（[^ a-zA-Z0-9\\\ ._] +，_）;

I am new in java mail polling and i have create one type of conversation application in this if user send mail to each other then i read that from them mail and post as new message in conversation.

解决方案
I have found the solution to download the inline images + icons from the mail.
private String getAttachments(Message message, HttpServletRequest request) throws MessagingException, IOException {
String contentType = message.getContentType();
String attachFiles="";
if (contentType.contains("multipart")) {
// content may contain attachments
Multipart multiPart = (Multipart) message.getContent();
int numberOfParts = multiPart.getCount();
for (int partCount = 0; partCount < numberOfParts; partCount++) {
MimeBodyPart part = (MimeBodyPart) multiPart.getBodyPart(partCount);
String disposition =part.getDisposition();
String file=part.getFileName();
//External attachments
if (disposition != null && Part.ATTACHMENT.equalsIgnoreCase(disposition)) {
// this part is attachment
String fileName = new Date().getTime()+ "_"+ part.getFileName().replaceAll("[^a-zA-Z0-9\\._]+", "_"); //To make attachment name uniq we are adding current datatime before name.
attachFiles += fileName + ","; //concrete all attachment's name with comma separated.
part.saveFile(new File(request
.getSession()
.getServletContext()
.getRealPath(
"/WEB-INF/attechments/"
+ fileName))); //To save the attachment file at specific location.
// LOG.info("\n\t Path :- " +request.getSession().getServletContext().getRealPath("/WEB-INF/attechments/" + fileName));
}
//Inline Attachments
else if (disposition != null && Part.INLINE.equalsIgnoreCase(disposition)) {
// this part is attachment
String fileName = new Date().getTime()+ "_"+ part.getFileName().replaceAll("[^a-zA-Z0-9\\._]+", "_"); //To make attachment name uniq we are adding current datatime before name.
// attachFiles += fileName + ","; //concrete all attachment's name with comma separated.
part.saveFile(new File(request
.getSession()
.getServletContext()
.getRealPath(
"/WEB-INF/attechments/"
+ fileName))); //To save the attachment file at specific location.
// LOG.info("\n\t Path :- " +request.getSession().getServletContext().getRealPath("/WEB-INF/attechments/" + fileName));
}
//Inline icons and smileys
else if(file != null && disposition==null)
{
String fileName = new Date().getTime()+ "_"+ part.getFileName().replaceAll("[^a-zA-Z0-9\\._]+", "_");
// attachFiles += fileName + ","; //concrete all attachment's name with comma separated.
part.saveFile(new File(request
.getSession()
.getServletContext()
.getRealPath(
"/WEB-INF/attechments/"
+ fileName)));
}
}
}
if (attachFiles.length() > 1) {
attachFiles = attachFiles.substring(0, attachFiles.length() - 1);
}
return attachFiles;
}
