Question

我正在尝试使用 Alfresco 4.2e 在 java 中插入带有自定义属性的文档。现在插入的值没有任何错误，但是未设置自定义属性的值，它显示为null。

这是我的代码：

    Map<String, String> props = new HashMap<String, String>();
    props.put(PropertyIds.NAME, newDocName);
    props.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document,P:kb:referencable");
    props.put("kb:documentRef", "123");
    props.put("kb:documentID", "1234");
    String content = "sample=================";
    byte[] buf = null;
    try {
        buf = content.getBytes("UTF-8");
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
    ByteArrayInputStream input = new ByteArrayInputStream(buf);
    ContentStream contentStream = session.getObjectFactory()
            .createContentStream(newDocName, buf.length,
                    "text/plain; charset=UTF-8", input);
    target.createDocument(props, contentStream, VersioningState.MAJOR);

Serach查询：

    String query = "SELECT * FROM kb:referencable ";
    ItemIterable<QueryResult> queryResult = session.query(query, false);
    for (QueryResult item : queryResult) {
         System.out.println("item="+item.getProperties());

    }

以下是搜索输出：

kb：documentRef和kb：documentID（custom property）的值为null。

Answer 1

老实说，我不知道kb：documentRef是否被解析为简写，但传递的props地图必须是这种类型：

Map<QName,Serializable> props = new Map<QName,Serializable>();

然后假设模型中的命名空间为http://www.custommodel.com/kb/1.0，您应该这样做：

props.put(new QName("http://www.custommodel.com/kb/1.0","documentRef"), "123");
props.put(new QName("http://www.custommodel.com/kb/1.0","documentID"), "1234");

或者，更好的是，您可以编写便捷的界面：

public interface MyModel {
   KB_DOCUMENT_REF = new QName("http://www.custommodel.com/kb/1.0","documentRef");
}

然后，更清楚：

props.put(MyModel.KB_DOCUMENT_REF, "123");
