【Bonita BPM】Documents 複數檔案上傳到Alfresco

tags: Bonita BPM Alfresco

Common 先期知識

• 單一檔案上傳：【Bonita BPM】Document 檔案上傳到Alfresco，並取得URL
• 使用方法：OpenCMIS
• 程式碼分為2部分
  • Groovy Scripts
  • Connectors 的 Scripts

Code 程式碼

Connectors 的 Scripts

1. serialDocumentReference的設定：將檔案設定成 Multiple
   • Document 檔案上傳
2. Document 請參考：
   • 在Script呼叫Document 檔案
   • Document 檔案的各種Type
3. Local variables：equipmentId
4. Parameters：alfrescoHost, alfrescoUsername, alfrescoPassword, alfrescoFolderPath
5. documentNum：另外取得 “keepDocumentReference” 的 size()

List<String> fileNameList = new ArrayList<String>()
List<String> mimeTypeList = new ArrayList<String>()
List<Byte[]> fileContentList = new ArrayList<Byte[]>()
List<Long> equipmentIdList = new ArrayList<Long>()

List<Document> documentList = apiAccessor.getProcessAPI().getDocumentList(processInstanceId, "keepDocumentReference", 0, documentNum)

for(int i=0; i<documentNum; i++){
    String contentFilename = documentList.get(i).getContentFileName() //取得完整檔名(包含副檔名e.g. test.jpg)
    String contentStorageId = documentList.get(i).getContentStorageId()
    //equipmentId，請自行加入

    fileNameList.add(contentFilename.substring(contentFilename.lastIndexOf("."))) //取得副檔名
    mimeTypeList.add(documentList.get(i).getContentMimeType())
    fileContentList.add(apiAccessor.getProcessAPI().getDocumentContent(contentStorageId))
    equipmentIdList.add(equipmentId)
}

UploadToAlfresco.uploadFile(fileContentList,fileNameList,mimeTypeList,equipmentIdList,alfrescoHost,alfrescoUsername,alfrescoPassword,alfrescoFolderPath)

Groovy Scripts

• 複數檔案上傳功能

String alfrescoHostName = alfrescoHost;
String username = alfrescoUsername; //Alfresco使用者帳密
String password = alfrescoPassword;

//======== connection alfresco by openCMIS ========

SessionFactory sessionFactory = SessionFactoryImpl.newInstance();
Session lSession = sessionFactory.getRepositories(sessionParameters).get(0).createSession();

//使用者根目錄（My files）
Folder root = (Folder) lSession.getObjectByPath(alfrescoFolderPath);

for(int i=0; i<fileNameList.size(); i++){
    //== InputStream Get ==
    InputStream stream = new ByteArrayInputStream(fileContentList.get(i));

    //== properities ==
    String extension = fileNameList.get(i).substring(fileNameList.get(i).lastIndexOf("."))
    Map<String, Object> lProperties = new HashMap<String, Object>();
    StringBuilder nameSB = new StringBuilder();
    nameSB.append("equipment");
    nameSB.append(equipmentIdList.get(i));
    nameSB.append("_0");
    nameSB.append(extension)
    String name = nameSB.toString();
    String mimeType = fileMimeTypeList.get(i);
    lProperties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document");
    lProperties.put(PropertyIds.NAME, name);

    ContentStream contentStream = new ContentStreamImpl(name, new BigInteger("" + fileContentList.get(i).length), mimeType, stream);
    Document upFile =  root.createDocument(lProperties, contentStream, null);
