我在Alfresco社区4.0工作。
我使用cmis来更新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该文件的内容。我用了这个方法:
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java项目中使用了这个jar:

所有的jars都被添加到类路径中,但是当我测试我的应用程序时,我得到了以下错误:

更新了:
我发现在Alfresco社区4.0.0
我应该使用化学开放客户端0.6.0和
此外,我还应该在代码中使用这个URL:http://localhost:9080/alfresco/cmisatom
我尝试使用以下代码与cmis进行会话,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();就像我说的,我用了这个罐子:

我从chemistry-opencmis-client-impl-0.6.0-with-dependencies.tar.gz下载了所有lib,我还下载了这个jar、0.2.jar
当我测试时,我也有同样的错误。
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,而与我的java代码无关,但我试图更改,但没有成功。
parameter.put(SessionParameter.ATOMPUB_URL, "http://localhost:9080/alfresco/cmisatom");有:
parameter.put(SessionParameter.ATOMPUB_URL, "http://localhost:9080/alfresco/service/cmis");发布于 2016-05-09 07:58:17
我不确定这是否是正确的答案,但希望你会发现错误和一些提示。

我假设您使用另一个类路径运行测试,然后显示在屏幕截图中。
Caused by: java.lang.ClassNotFoundException: org.apache.chemistry.opencmis.client.api.SessionFactory
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1387)你在tomcat容器里做测试吗?在开始测试时仔细检查类路径。如果类路径确实有cmis依赖项,那么检查cmis客户端版本冲突。所有冲突版本都可以由maven (例如)轻松地解决。我建议将项目创建为maven项目,以消除此问题。此外,在运行测试时,maven将在类路径中包含所有cmis依赖项。
