云苍穹附件携带

1.通过AttachmentServiceHelper.getAttachments()获取源附件：

List<Map<String,Object>> attachments = AttachmentServiceHelper.getAttachments("cas_claimbill",claimbillPK,"attachmentpanel");

2.附件地址和最近修改时间不能直接使用：

if(attachment.get("lastModified") instanceof Date){
　　Date date = (Date)attachment.get("lastModified");
　　attachment.put("lastModified",date.getTime());
}
if(attachment.containsKey("attPkId")){
　　DynamicObject dbAttachment = BusinessDataServiceHelper.londSingle(attachment.get("attkId")," bos_attachment","ffileid");
　　attachment.put("url",dbAttachment.getstring("ffileid"));
}

3.上传附件到目标单：

AttachmentServiceHelper.upload("cas_recbill", recbillPK,"attachmentpanel", attachments);
