Question

我创建了一个显示邮件的电子邮件客户端，当我点击回复时，应该使用附件回复邮件，但我的enctype='multipart/form-data'>并未接受bodypart.getContent()或任何其他方法。请尽快帮助我解决这个问题，因为我必须接受我的项目。

composereplymail.jsp

<%@ page import="user.*" %>
<%@ page import="javax.mail.*" %>
<%@ page import="javax.mail.internet.*" %>
<%@ page import="javax.activation.*" %>
<%@ page import="java.io.*" %>
<%
    String sendmessage=(String)request.getAttribute("sendmessage");
    if(sendmessage==null)
    {
        sendmessage="";
    }

    if (session == null) {
        response.sendError(404, "Session expired");
        return;
    }
    userinfo info = (userinfo)session.getAttribute("userinfo");

    Session sessio = info.getSession();
    Store store = sessio.getStore("imap");
      store.connect(info.getHostname(),info.getusername(),info.getpassword());
    Folder folder = store.getFolder(info.getUrl()); 
    folder.open(Folder.READ_WRITE);
    Integer messageno=Integer.parseInt(request.getParameter("messageno"));
    Message[] message = folder.getMessages();
    String subject=message[messageno].getSubject();

我并不完全清楚你要做什么......

通常，在回复邮件时，不要希望回复包含原始邮件的所有附件。

无论如何，您绝对不希望仅将附件发送到浏览器客户端，以便它可以作为附件发送给您。也许您真正想要的是允许用户选择将附加到回复的文件？

JavaMail下载包包括几个演示程序，一个基于servlet，一个基于JSP，你看过它们吗？

如何回复包含附件的邮件？
