泛微OA文档附件复制汇集-平芜编程栈

实现场景：

目标：实现将流程相关资源中附件与文档内容复制到新字段中

使用泛微ESB实现复制相关资源文档，附件的docid到新字段中实现附件汇集

附件1 字段存有a.txt,b.pdf; 附件2 字段存有 c.xls,d.ppt; 文档字段3 存有 d.doc在线文档
在新增的自定义字段collectannex，通过esb接口实现将以上内容复制到该字段中

ESB思路：

最后更新表单要去除获取到的docid之间的空格！！！

实现思路：

通过流程requestid 获取表名与流程创建者id
通过1中的内容获取流程相关资源的文件docid
复制所有相关资源中的docid生成复制后新的docid
执行更新SQL实现将以上新生成的docid复制到新字段（collectannex）中

代码解析：

使用requestid获取流程对应的表名与创建人需要进行多个表的转换，queryTableNameSQL获取tablename（表名）拆解来源如下：

select creater from workflow_requestbase where requestid = 80095263 -- workflowid 448621 select * from workflow_base where id = 448621 --- formid -4654 select tablename from workflow_bill where id = -4654 -- tablename

获取相关资源，在之前的获取流程相关资源文章提到了获取相关流程requestid（参数为1），参数为2或者3即可获取相关资源的文档和附件docid；
```
代码不同数字代表不同资源类型，其中 1:相关流程 2：相关文档 3：相关附件 ；
```

以下方法通过输入流程requestid与创建人id返回该流程相关资源中所有文档与附件的docid：

static List<String> getAnnexfilesList(String requestidStr,String creatoridStr){ List<String> docidList = new ArrayList<>() ; int requestid = Integer.parseInt(requestidStr) ; int useridInt = Integer.parseInt(creatoridStr) ; if(requestidStr.equals("")||requestidStr==null){ return null ; } User user = new User(useridInt) ; try { RequestInfoEntity infoEntity = RequestBaseBiz.loadRequestInfo(requestid); int workflowid = infoEntity.getWorkflowId(); WorkflowComInfo comInfo = new WorkflowComInfo(); int isbill = Util.getIntValue(comInfo.getIsBill(Util.null2String(workflowid))); int formid = Util.getIntValue(comInfo.getFormId(Util.null2String(workflowid))); RequestResources reqResources = new RequestResources(user, infoEntity.getWorkflowId(), requestid, isbill, formid, "", "", "", "0", 0, 0); // "type":资源类型 1:相关流程 2：相关文档 3：相关附件 String fromSql = reqResources.getReqResSqlByType(3); String querySQL = "select id, resname, restype, creator, creatortype, createdate, docid from " + fromSql + " order by id asc"; RecordSet rs = new RecordSet(); rs.executeQuery(querySQL); while (rs.next()) { int id = rs.getInt("id"); rs.getString("creator"); //文档类型的附件，查出来的是docid，还要根据docid去查询docImageFileId String docid = Util.null2String(rs.getInt("docid")); String imagefileid = getDocImageFileIdByDocid(docid).get("imagefileid").toString(); docidList.add( docid); } // "type":资源类型 1:相关流程 2：相关文档 3：相关附件 fromSql = reqResources.getReqResSqlByType(2); querySQL = "select id, resname, restype, creator, creatortype, createdate, docid from " + fromSql + " order by id asc"; rs.executeQuery(querySQL); while (rs.next()) { int id = rs.getInt("id"); rs.getString("creator"); //文档类型的附件，查出来的是docid，还要根据docid去查询docImageFileId String docid = Util.null2String(rs.getInt("docid")); String imagefileid = getDocImageFileIdByDocid(docid).get("imagefileid").toString(); // imagefileidList.add( imagefileid); docidList.add( docid); } }catch (Exception e) { // writeLog(e.getMessage(), e); } return docidList ; }

将docid复制后存入新的字段（collectannex）中前需要复制生成新的文件docid

public String createDocument(InputStream inputStream, String filePath, String fileName, String userid, User user, String wdmc) throws Exception { // System.out.println("+++++++++++++++++++++++++++++++++++++++++++进入生成文档方法+++++++++++++++++++++++++++++++++++++++++++"); String docid = ""; List<InputStream> inputStreams = new ArrayList<>(); byte[] content = new byte[102400]; // 上传附件，创建html文档 content = null; try { int byteread; byte data[] = new byte[1024]; // InputStreamReader reader = new InputStreamReader(input,"UTF-8"); ByteArrayOutputStream out = new ByteArrayOutputStream(); while ((byteread = inputStream.read(data)) != -1) { out.write(data, 0, byteread); out.flush(); } content = out.toByteArray(); inputStream.close(); out.close(); } catch (Exception e) { e.printStackTrace(); } DocAttachment da = new DocAttachment(); da.setDocid(0); da.setImagefileid(0); da.setFilecontent(org.apache.axis.encoding.Base64.encode(content)); da.setFilerealpath(filePath); da.setIszip(1); da.setFilename(fileName); da.setIsextfile("1"); da.setDocfiletype("3"); DocServiceImpl docService = new DocServiceImpl(); DocInfo doc = new DocInfo();//创建文档 doc.setDoccreaterid(Integer.parseInt(userid));// doc.setDoccreatertype(0); doc.setAccessorycount(1); doc.setMaincategory(Integer.parseInt("92"));//主目录id doc.setSeccategory(Integer.parseInt("92"));//子目录id doc.setOwnerid(Integer.parseInt(userid)); doc.setDocStatus(1); doc.setId(0); doc.setDocType(2); doc.setDocSubject(wdmc); doc.setDoccontent(""); doc.setAttachments(new DocAttachment[]{da}); int newDocid = docService.createDocByUser(doc, user); System.out.println("新文档id：" + newDocid); return newDocid + ""; } public static Map<String, String> getImageFileidByDocid(String docid) { String sql = "select imagefileid,imagefilename from docimagefile where docid='" + docid + "'"; RecordSet rs = new RecordSet(); rs.executeQuery(sql); Map<String, String> map = new HashMap<>(); if (rs.next()) { map.put("imagefileid", weaver.general.Util.null2String(rs.getString("imagefileid"))); map.put("imagefilename", (weaver.general.Util.null2String(rs.getString("imagefilename"))).replace("/","-")); } return map; }

代码中方法getImageFileidByDocid 输入文件docid获取对应的imagefileid与imagefilename，作为获取新文档docid方法createDocument的参数，具体通过遍历上一步获取到所有资源docid的list循环生成，代码如下：

for(String docId : docidList){ Map<String, String> imageInfo = getImageFileidByDocid(docId); String decodeimagefileid = Util.null2String(DecodeUtil.decodeByImageFileIdByTianyu(Integer.parseInt(imageInfo.get("imagefileid")))); String imagefilename = imageInfo.get("imagefilename"); InputStream inputStream = ImageFileManager.getInputStreamById(Integer.parseInt(decodeimagefileid)); String relatedDocid= createDocument(inputStream,"/app/weaver/ecology/Archives",imagefilename,creater,user,imagefilename); CollectAnnexDocidList.add(relatedDocid); }
