Question

我正在使用emailBean from Tony McGuckin发送HTML电子邮件。

在您保存并重新打开文档之前，它可以正常工作;那时豆子找不到附件。

考虑这种情况：

创建文档并将其另存为草稿
再次打开文档，然后单击“提交操作”，它将调用emailBean的逻辑

在debugmode上运行bean我看到它打印出Add Attachments ...

但是，这里没有获得附件EmbeddedObject eo = this.getDocument().getDocument().getAttachment(persistentName);

如果我尝试打印persistentName，我会得到空

这是emailBean：

            // add attachments....
            final List<FileRowData> attachments = this.getDocument().getAttachmentList(this.getFieldName());
            if(null != attachments && !attachments.isEmpty()){
              if(this.isDebugMode()){
                System.out.println("Adding Attachments...");
              }
                for(FileRowData attachment : attachments) {
                emailRootChild = emailRoot.createChildEntity();
                if(null != emailRootChild && attachment instanceof AttachmentValueHolder){
                  InputStream is = null;
                  try {                   

                    String persistentName = ((AttachmentValueHolder)attachment).getPersistentName();
                    String cid = ((AttachmentValueHolder)attachment).getCID();

                    //Here is printing null for persistentName
                    System.out.println("Attachment: " + persistentName);

                    EmbeddedObject eo = this.getDocument().getDocument().getAttachment(persistentName);
                    if(null != eo){
                      emailHeader = emailRootChild.createHeader("Content-Disposition");
                      emailHeader.setHeaderVal("attachment; filename=\"" + persistentName + "\"");
                      emailHeader = emailRootChild.createHeader("Content-ID");
                      emailHeader.setHeaderVal("<" + cid + ">");
                      is = eo.getInputStream();
                      Stream stream = session.createStream();
                      stream.setContents(is);
                      emailRootChild.setContentFromBytes(stream, attachment.getType(), MIMEEntity.ENC_IDENTITY_BINARY);
                      if(this.isDebugMode()){
                        System.out.println("Added Attachment : " + persistentName);
                      }
                    }
                  } catch (Exception e) {
                    if(this.isDebugMode()){
                      System.out.println("Adding Attachment failed : " + e.getMessage());
                    }
                    throw e;
                  } finally {
                    if(null != is){
                      is.close();
                      is = null;
                    }
                  }
                }
                }
              if(this.isDebugMode()){
                System.out.println("Completed Adding Attachments");
              }
            }

AttachmentValueHolder字段中的附件是持久性的还是非持久性的。尚未保存的新附件将包含persistentName。否则它将有一个name。您可以添加以下行来确定：

if(StringUtil.isEmpty(persistentName)) {
    persistentName=((AttachmentValueHolder)attachment).getName();
}

PS。因此，如果persistentName为null，则它将不再是持久名称。我没有更改变量名称而不是破坏你的代码：）

来自Tony McGuckin的emailBean在保存并重新打开文档后没有获取附件
