我使用的是Alfresco Community 4.0。
我使用CMIS更新了在Alfresco中的一个文档。
我已经在Alfresco注册了一个文档,这是保存方法后检索到的文档ID:b08e8bce-1b88-489e-a357-1e6385f180a1
现在我想用其他内容更改此文件的内容。 我使用了这个方法:
public void saveVersioning(File file, String filename, String userName, String pwd, String docId)
throws Exception {
SessionFactory factory = SessionFactoryImpl.newInstance();
Map<String, String> parameters = new HashMap<String, String>();
// User credentials.
parameters.put(SessionParameter.USER,userName);
parameters.put(SessionParameter.PASSWORD, pwd);
// Connection settings.
parameters.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());
parameters.put(SessionParameter.ATOMPUB_URL, "http://localhost:9080/alfresco/service/cmis"); // URL to your CMIS server.
// Create session.
// Alfresco only provides one repository.
Repository repository = factory.getRepositories(parameters).get(0);
Session session = repository.createSession();
System.out.println("Connected to repository:" + session.getRepositoryInfo().getName());
System.out.println("Repository id:"+session.getRepositoryInfo().getId());
// Get the contents of the file
Document doc = (Document) session.getObject(docId);
ContentStream contentStream = doc.getContentStream(); // returns null if the document has no content
if (contentStream != null) {
String mimetype = "text/plain; charset=UTF-8";
String content = "";
if (contentStream != null) {
filename = contentStream.getFileName();
mimetype = contentStream.getMimeType();
content = getContentAsString(contentStream);
System.out.println("file name "+filename);
System.out.println("minetype "+mimetype);
System.out.println("content "+content);
}
String updatedContents = content + "\nLine added in new version";
byte[] buf = updatedContents.getBytes("UTF-8");
ByteArrayInputStream input = new ByteArrayInputStream(buf);
contentStream = session.getObjectFactory().createContentStream(
filename, buf.length, mimetype, input);
System.out.println("Document version history");
{
List<Document> versions = doc.getAllVersions();
for (Document version : versions) {
System.out.println("\tname: " + version.getName());
System.out.println("\tversion label: " + version.getVersionLabel());
System.out.println("\tversion series id: " + version.getVersionSeriesId());
System.out.println("\tchecked out by: "
+ version.getVersionSeriesCheckedOutBy());
System.out.println("\tchecked out id: "
+ version.getVersionSeriesCheckedOutId());
System.out.println("\tmajor version: " + version.isMajorVersion());
System.out.println("\tlatest version: " + version.isLatestVersion());
System.out.println("\tlatest major version: " + version.isLatestMajorVersion());
System.out.println("\tcheckin comment: " + version.getCheckinComment());
System.out.println("\tcontent length: " + version.getContentStreamLength()
+ "\n");
}
}
}
}
我将使用以下代码调用此方法:
File file = new File("C:/test.pdf");
saveVersioning(file, "test.pdf", "admin","admin","b08e8bce-1b88-489e-a357-1e6385f180a1");
我在我的Java项目中使用了这个jar包: 所有的jar包都已经添加到了类路径中,但是当我测试我的应用程序时,我遇到了以下错误:

我的 Alfresco Community 4 服务器包含这个 jar 文件:
更新:
我发现在 Alfresco Community 4.0.0 版本中,我应该使用 chemistry-opencmis-client 0.6.0 和 alfresco-opencmis-extension-0.2.jar。
此外,在我的代码中,我应该使用这个 URL:http://localhost:9080/alfresco/cmisatom
我尝试使用以下代码获取 cmis 会话,但没有成功:
Map<String, String> parameter = new HashMap<String, String>();
// user credentials
parameter.put(SessionParameter.USER, "admin");
parameter.put(SessionParameter.PASSWORD, "admin");
// connection settings
parameter.put(SessionParameter.ATOMPUB_URL, "http://localhost:9080/alfresco/cmisatom");
parameter.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());
// create session
SessionFactory factory = SessionFactoryImpl.newInstance();
Session session = factory.getRepositories(parameter).get(0).createSession();
如我所说,我使用了这个jar包:
我从chemistry-opencmis-client-impl-0.6.0-with-dependencies.tar.gz下载了所有的库,并且我还下载了这个jar包alfresco-opencmis-extension-0.2.jar。
当我测试时,我遇到了相同的错误。
我在我的代码中添加了这一行:
parameter.put(SessionParameter.OBJECT_FACTORY_CLASS, "org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl");
我认为这个问题与缺少jar包版本有关,而不是我的Java代码有问题。但是我尝试更改这一行,但没有成功:
parameter.put(SessionParameter.ATOMPUB_URL, "http://localhost:9080/alfresco/cmisatom");
使用:
parameter.put(SessionParameter.ATOMPUB_URL, "http://localhost:9080/alfresco/service/cmis");
