JavaXPages：将MIME多部分从邮件复制到另一个Richtext文档

Question

试图通过将邮件正文保存到richtext项目中来从电子邮件创建新的XPages文档，我的文档已正确创建attachmentBody也已创建，但文档中所有嵌入的图像都已替换为ImagePlaceHolder，下面是创建附件和图像的方法

private static void parseMimeEntity(RichTextItem attachmentBody, MIMEEntity entity,Session session,File tmpFolder,String fileSeparator,long attachmentNumber) {
    MIMEEntity child;
        try{        
            if(!entity.getContentType().equalsIgnoreCase("text")){
                String filename = null; 
                MIMEHeader header = null;
                header = entity.getNthHeader("Content-Disposition");    
                if (header != null) {
                    filename = header.getParamVal("filename");
                    filename = filename.replace("\"", "");
                    if ("".equals(filename)) filename = null;
                }
                if (filename == null) {
                    // when filename is null
                    filename = "Attachment" + attachmentNumber++ + ".txt";
                }
                String contentDisposition = entity.getNthHeader("Content-Disposition").getHeaderVal();

                if(contentDisposition.equalsIgnoreCase("inline")){                      
                    String contentType = entity.getNthHeader("Content-Type").getHeaderVal();                        
                    Stream stream = session.createStream();
                    if (stream.open(file.getAbsolutePath(), "binary")) {
                        entity.setContentFromBytes(stream, contentType, MIMEEntity.ENC_IDENTITY_BINARY);                        
                        stream.close();
                    }
                }else{

                Stream stream = session.createStream();
                if (stream.open(file.getAbsolutePath(), "binary")) {
                    entity.getContentAsBytes(stream);                           
                    stream.close();
                }                   
                attachmentBody.embedObject(EmbeddedObject.EMBED_ATTACHMENT, "", file.getAbsolutePath(), filename);      
                }   
                file.delete();
            }
        }
        catch(Exception ex){                
            System.out.println("NO FILE");
        }
        child = entity.getFirstChildEntity();
        if (child != null) {
            parseMimeEntity(attachmentBody, child,session,tmpFolder,fileSeparator,attachmentNumber);
        }
        child = entity.getNextSibling();
        if (child != null) {
            parseMimeEntity(attachmentBody, child,session,tmpFolder,fileSeparator,attachmentNumber);
        }   
    }

一种解决方案是对嵌入的图像进行Base64编码，而不是将嵌入的图像添加为附件。请看我的答案：https://stackoverflow.com/a/19328276/785061

Answer 2

当您创建一个新的mime条目时，您将获得新的边界字符串，作为嵌入图像的键。检查传入图像的src属性以了解确切的格式

您需要调整这些属性以使图像正确显示。清理HTML并不是一件有趣的事情，请参考本文中的一些要点：

最终（需要检查，我不知道），您可以指定边界并保存HTML清理
