我的代码是这样的



@RequestMapping("four_download")

public void fourDownload(HttpSession session, HttpServletResponse response,HttpServletRequest request) throws Exception

{	

response.setContentType("text/html;charset=utf-8");

PrintWriter out = response.getWriter();

//获得当前邮件用户

JamesUser juser = JamesUserUtil.getJamesUser(session);	

//获得邮件用户具体信息 获得密码

UserInfo userinfo = JamesUserUtil.getUserInfo(session);

//获得邮件ID

long uid = Long.parseLong(request.getParameter("uid"));

//获得邮箱类型

int folderType = Integer.parseInt(request.getParameter("folderType"));

//获得附件的编号

int bodyId = Integer.parseInt(request.getParameter("bodyId"));

//获得文件名

String fileName = request.getParameter("fileName");



fileName=java.net.URLDecoder.decode(fileName,"UTF-8");



ReceiveMail mail = new ReceiveMail(juser.getUserName(), userinfo.getUserPass());// 初始化接收邮件参数



IMAPFolder folder = mail.openFolder(userReceiveMailService.folderType(folderType), Folder.READ_WRITE);



Message message = folder.getMessageByUID(uid);



response.setHeader("Content-Disposition", "attachment;filename="+fileName);



Multipart multipart = (Multipart) message.getContent();



BodyPart bodyPart = multipart.getBodyPart(bodyId);



InputStream input = bodyPart.getInputStream();

int temp = 0;

while((temp = input.read()) != -1){

out.write(temp);

}

//mail.handleMultipart(message);

//userReceiveMailService.attachmentDownLoad(juser.getUserName(), userinfo.getUserPass(),1, uid, fileName);

}
