alfresco - 使用 java 实现在 Alfresco 中上传文件

Question

建议我使用 java 将文件上传到 Alfresco 的任何基本示例。我是 Alfresco 的新手。

Answer 1

这是一个使用 Python 和cmislib的示例：

>>> from cmislib import CmisClient
>>> client = CmisClient('http://cmis.alfresco.com/cmisatom', 'admin', 'admin')
>>> repo = client.defaultRepository
>>> root = repo.rootFolder
>>> someFolder = root.createFolder('someFolder')
>>> someFile = open('test.txt', 'r')
>>> someDoc = someFolder.createDocument('Test Document', contentFile=someFile)

这是一个使用 Java 和OpenCMIS的示例：

// default factory implementation
SessionFactory factory = SessionFactoryImpl.newInstance();
Map<String, String> parameter = new HashMap<String, String>();

// user credentials
parameter.put(SessionParameter.USER, "Otto");
parameter.put(SessionParameter.PASSWORD, "****");

// connection settings
parameter.put(SessionParameter.ATOMPUB_URL, "http://<host>:<port>/cmis/atom");
parameter.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());
parameter.put(SessionParameter.REPOSITORY_ID, "myRepository");

// create session
Session session = factory.createSession(parameter);
Folder root = session.getRootFolder();

// properties
// (minimal set: name and object type id)
Map<String, Object> properties = new HashMap<String, Object>();
properties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:folder");
properties.put(PropertyIds.NAME, "a new folder");

// create the folder
Folder parent = root.createFolder(properties);

String name = "myNewDocument.txt";

// properties 
// (minimal set: name and object type id)
Map<String, Object> properties = new HashMap<String, Object>();
properties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document");
properties.put(PropertyIds.NAME, name);

// content
byte[] content = "Hello World!".getBytes();
InputStream stream = new ByteArrayInputStream(content);
ContentStream contentStream = new ContentStreamImpl(name, BigInteger.valueOf(content.length), "text/plain", stream);

// create a major version
Document newDoc = parent.createDocument(properties, contentStream, VersioningState.MAJOR);

在露天使用 Java 和 OpenCMIS 的示例： 下载 OpenCMIS jars（版本 1.1.0 -> Commodity Packages -> Package -> OpenCMIS Client with dependencies）

    properties.put(PropertyIds.NAME, "MyAlfrescoFolder");

    // create the folder
    Folder parent = root.createFolder(properties);

    String name = "NewTextFile.txt";

    // properties
    Map<String, Object> properties2 = new HashMap<String, Object>();
    properties2.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document");
    properties2.put(PropertyIds.NAME, name);

    // content
    byte[] content = "Hello Parth Patel!".getBytes();
    InputStream stream = new ByteArrayInputStream(content);
    ContentStream contentStream = new ContentStreamImpl(name, BigInteger.valueOf(content.length), "text/plain", stream);

    // create a major version
    Document newDoc = parent.createDocument(properties2, contentStream, VersioningState.MAJOR);

    System.out.println("DONE.");

  }

}

在 Web 服务库的帮助下，我们可以使用 java 连接到 alfresco。您可以在下面找到示例代码

WebServiceFactory.setEndpointAddress("url");
WebSererviceFactory.setEndpointAddress("url");
        AuthenticationUtils.startSession(prop.getProperty("user"),prop.getProperty("password"));
        System.out.println(AuthenticationUtils.getTicket());
        ContentServiceSoapBindingStub contService =      WebServiceFactory.getContentService();

创建父引用：

         String path = "/app:company_home/cm:dir" + </pre>

        ParentReference parRef = new ParentReference(STORE, null,path,ASSOC_CONTAINS, "{"+ Constants.NAMESPACE_CONTENT_MODEL + "}"+ fileName); </pre>

       parRef.setPath("/app:company_home/cm:vasanpmsrole");
        String name = fileName;
        ContentFormat contentFormat =
                new ContentFormat(mimeType, "UTF-8");
        NamedValue[] properties = new NamedValue[ {Utils.createNamedValue(Constants.PROP_NAME, fileName)};

        CMLCreate create = new CMLCreate("1",parRef, null, null, null,Constants.TYPE_CONTENT, properties);
        CML cml = new CML();
        cml.setCreate(new CMLCreate[]{create});
        UpdateResult[] result =    WebServiceFactory.getRepositoryService().update(cml) ;
        Reference newContentNode =
                result[0].getDestination();
        Content content = contService.write(
                newContentNode, Constants.PROP_CONTENT,
                b, contentFormat);

         strUuid = newContentNode.getUuid();

在此我使用了以下目录：

• 轴1.4.jar
• AlfrescoWebService.jar
