无法在Java CMIS中获得Alfresco 4.2存储库会话

Question

我想获得Alfresco 4.2.1存储库的会话。但我没有得到低于例外

Exception in thread "main" org.apache.chemistry.opencmis.commons.exceptions.CmisConnectionException: Cannot access "https://test.uk.corplan.net/alfresco/api/-default-/public/cmis/versions/1.1/atom": handshake alert:  unrecognized_name

我写了下面的代码来获取会话。但我在这里没有弄错。

import java.util.HashMap;
import java.util.Map;
import org.apache.chemistry.opencmis.client.api.Session;
import org.apache.chemistry.opencmis.client.api.SessionFactory;
import org.apache.chemistry.opencmis.client.runtime.SessionFactoryImpl;
import org.apache.chemistry.opencmis.commons.SessionParameter;
import org.apache.chemistry.opencmis.commons.enums.BindingType;

public class GetAlfrescoSession {
    public static void main(String[] args) {
        getalfrescosession();
    }

    public static Session getalfrescosession() {
        Map<String, String> parameter = new HashMap<String, String>();
        parameter.put(SessionParameter.USER, "admin");
        parameter.put(SessionParameter.PASSWORD, "admin");
        parameter.put(SessionParameter.ATOMPUB_URL,
                "https://test.uk.corplan.net/alfresco/api/-default-/public/cmis/versions/1.1/atom");
        parameter.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());
        parameter.put(SessionParameter.OBJECT_FACTORY_CLASS, "org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl");
        SessionFactory factory = SessionFactoryImpl.newInstance();
        Session session = factory.getRepositories(parameter).get(0).createSession();
        return session;
    }
}

有人可以帮助我吗？

提前致谢...

Answer 1

我相信您使用的网址仅与Alfresco 5.x兼容。如果您使用Alfresco 4.2.x，则需要使用其他URL。只需打开页面：

http://<your alfresco>/alfresco/s/cmis/index

您应该获得与您的实例相关的所有详细信息。 CMIS回购的URL应为：

http://<your alfresco>/alfresco/cmisatom

Answer 2

这与Alfresco或OpenCMIS无关。 SSL未在服务器上正确设置。

看到这个答案： SSL handshake alert: unrecognized_name error since upgrade to Java 1.7.0

Answer 3

我刚安装了最新的Alfresco 4.2.x并检查了网址：

http://127.0.0.1:8080/alfresco/s/cmis/index

然后，我点击了名为AtomPub Service Document的屏幕截图中突出显示的链接，CMIS服务的URL是：

http://127.0.0.1:8080/alfresco/cmisatom

请注意，Alfresco 4.2仅支持CMIS 1.0而不支持CMIS 1.1。

我在5.1版之前遇到过这个问题，为我修复的是以下设置：

            SessionFactory factory = SessionFactoryImpl.newInstance();
            Map<String, String> parameters = new HashMap<String, String>();

            // user credentials
            parameters.put(SessionParameter.USER, "username");
            parameters.put(SessionParameter.PASSWORD, "password");

            // connection settings
            parameters.put(SessionParameter.ATOMPUB_URL, "https://someurl.com/alfresco/cmisatom");
            parameters.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());
            parameters.put(SessionParameter.REPOSITORY_ID, "IMPORTANT! the repository id must be defined here");

            // create session
            Session session = factory.createSession(parameters);

如果您使用的是4.2版，则需要验证连接端点和您正在使用的CMIS版本是否兼容。
