我与Alfresco Community 4.0合作。
我使用 cmis 更新Alfresco中的文档。
我已经在Alfresco中注册了一个文档,这是在保存方法之后检索的文档ID: b08e8bce-1b88-489e-a357-1e6385f180a1
现在我想通过其他内容更改此文件的内容。我用这个方法:
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");
}
}
}
}
我使用此代码调用此方法:
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:
所有的jar都被添加到类路径中,但是当我测试我的应用程序时,我收到了这个错误:

我的Alfresco Community 4服务器包含此jar:
更新:
我在Alfresco Community 4.0.0发现了这一点 我应该使用 chemistry-opencmis-client 0.6.0 和 alfresco-opencmis-extension-0.2.jar
我也应该在我的代码中使用此网址:http://localhost:9080/alfresco/cmisatom
我尝试使用此代码尝试与cmis进行会话时没有成功:
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();
正如我所说,我用过这个罐子:
我从化学-opencmis-client-impl-0.6.0-with-dependencies.tar.gz下载了所有的lib,我也下载了这个jar alfresco-opencmis-extension-0.2.jar
当我测试时我有同样的错误。
我在代码中添加了这一行:
parameter.put(SessionParameter.OBJECT_FACTORY_CLASS, "org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl");
我认为问题与缺少jar版本有关,与我的java代码无关 但我尝试改变这一行没有成功:
parameter.put(SessionParameter.ATOMPUB_URL, "http://localhost:9080/alfresco/cmisatom");
with:
parameter.put(SessionParameter.ATOMPUB_URL, "http://localhost:9080/alfresco/service/cmis");
答案 0 :(得分:2)
我不确定这是否是正确答案,但希望您能找到错误和一些提示。
答案 1 :(得分:0)
我将假设您使用另一个类路径运行测试,然后在屏幕截图中显示。
Caused by: java.lang.ClassNotFoundException: org.apache.chemistry.opencmis.client.api.SessionFactory

您在tomcat容器中运行测试?开始测试时,请仔细检查类路径。如果classpath确实具有cmis依赖关系,请检查cmis客户端版本冲突。所有冲突版本都可以通过maven(例如)轻松解决。我建议将项目创建为maven项目以解决此问题。当你运行test时,maven还会在classpath中包含所有cmis依赖项。
