如何使用Apache Chemistry在对象上创建自定义属性 [英] How to create custom property on object using Apache Chemistry

问题描述

我正在使用Alfresco CMS的本地实例，并且正在使用Apache Chemistry Java CMIS. 一切都可以很好地浏览和创建对象，但是我很难在文档上添加元数据.

I'm working with a local instance of Alfresco CMS and I'm using the Apache Chemistry Java CMIS. Everything works well for browsing and creating objects, however I'm having a hard time adding metadata on documents.

在他们的源页面代码上有一个示例，说明您需要在CmisObject上调用updateProperties.不幸的是，这是行不通的，我已经声明了一个例外:Property 'my:property' is not valid for this type or one of the secondary types

There is an example on their source page code saying that you need to call updateProperties on the CmisObject. Unfortunately, this doesn't work, the exception I got stating: Property 'my:property' is not valid for this type or one of the secondary types

您知道如何添加自定义属性吗?我是否必须增强现有的方面集合，如果是的话，我该如何做?

Do you know how can I add a custom property? Do I have to enhance the existing aspects collection and if so, how can I do it?

谢谢.

推荐答案

属性'my:property'对此类型或其中一种辅助类型无效

Property 'my:property' is not valid for this type or one of the secondary types

my:property似乎是一个自定义属性，然后应使用自定义Alfresco方面进行处理.

my:property seems to be a custom property, and should then be handled with a custom Alfresco aspect.

如果要使用Alfresco方面，则需要

If you want to use Alfresco aspects, you will need the Alfresco OpenCMIS Extension

以下代码片段允许在OpenCMIS中使用Alfresco扩展:

The following code fragment allows to use the Alfresco Extension with OpenCMIS:

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:8080/alfresco/cmisatom");
parameter.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());

// set the alfresco object factory
parameter.put(SessionParameter.OBJECT_FACTORY_CLASS, "org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl");

// create session
SessionFactory factory = SessionFactoryImpl.newInstance();
Session session = factory.getRepositories(parameter).get(0).createSession();

以下代码允许创建一个新文档，其中填充了一个自定义属性:

The following code allows to create a new document with a custom property filled :

Map<String, Object> properties = new HashMap<String, Object>();
properties.put(PropertyIds.NAME, "doc1");
properties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document,my:docProps");
properties.put("my:property", "My document");

Document doc = session.getRootFolder().createDocument(properties, null, null);
