金蝶EAS，获取单据对应的所有附件（附件集合）

根据业务单据ID，获取该单据对应附件管理中的附件集合（多个附件）。

以下示例方法用于前端调用，如需用于后端，需要添加上下文ctx参数以及改变接口实例的获取方式。

/** * 获取单据对应的所有附件，用于前台 * @param billId 单据主键 */public static AttachmentCollection getAttachments(String billId) throws BOSException, EASBizException{AttachmentCollection attachments = null; //附件集合IBoAttchAsso iBoAttchAsso = BoAttchAssoFactory.getRemoteInstance(); //附件与业务对象关联接口EntityViewInfo view = new EntityViewInfo();FilterInfo filter = new FilterInfo();filter.getFilterItems().add(new FilterItemInfo("boID", billId));view.setFilter(filter);BoAttchAssoCollection coll = iBoAttchAsso.getBoAttchAssoCollection(view); //查询所关联附件if(VerifyUtil.isNull(coll)){return attachments;}attachments = new AttachmentCollection();IAttachment iAttachment = AttachmentFactory.getRemoteInstance();for(int i = 0; i < coll.size(); i++){BoAttchAssoInfo bo = coll.get(i); //附件关联对象    AttachmentInfo attachment = bo.getAttachment(); //附件对象attachment = iAttachment.getAttachmentInfo(new ObjectUuidPK(attachment.getId()));attachments.add(attachment);}return attachments;}
