附件上传主要涉及数据库表：
T_BAS_Attachment：附件表
T_BAS_BoAttchAsso：附件和业务单据关系表
T_HR_SHRAttachmentExt：sHR附件表
附件默认是存储在数据库的，以字节流的方式存放在T_BAS_Attachment表的FFile。
sHR标准附件上传逻辑：点击附件上传控件上传附件后，会同时在T_BAS_Attachment和T_HR_SHRAttachmentExt写入数据，T_HR_SHRAttachmentExt表此时的状态FState为20。点击保存单据时，会更新T_HR_SHRAttachmentExt的状态为10，并且往T_BAS_BoAttchAsso写入数据
如果需要将附件上传阿里OSS，并且不储存在数据库，可修改com.kingdee.shr.attachment.app.SHRAttachmentExtControllerBean的_updateAffterSaveForm方法。在保存单据的时候将T_BAS_Attachment表FFile的字节流取到，上传到阿里OSS，然后将T_BAS_Attachment表FFile清空，将阿里OSS文件路径存在T_BAS_Attachment的FRemotePath。下载时可以根据这个路径去阿里OSS下载。

这边使用的方式是先下载到服务端，再去服务端读取文件，最后把服务端的这个文件删除。
另外，员工信息列表界面有批量上传附件。这个需要改动com.kingdee.eas.hr.emp.web.util.PersonAttachmentBatchUploadHelper
