不能用Alfresco公共Java API创建节点，访问被拒绝。系统目前处于只读模式

问题描述 投票：0回答：1

我正在为Alfresco内容服务社区版6.2.0-ga开发一个模块，我不能通过以下方法创建节点 NodeService但我可以通过RestAPI和Share创建节点。

这是我的java代码，试图使用 NodeService 创建一个虚拟节点。

public EpicDocument upload(EpicDocument doc) {
    logger.info("creating new EpicDocument...");

    StoreRef storeRef = new StoreRef(StoreRef.PROTOCOL_WORKSPACE, "SpacesStore");
    NodeRef root = nodeService.getRootNode(storeRef);

    QName type = QName.createQName(EPIC_NAMESPACE_URI, "document");
    Map<QName, Serializable> props = new HashMap<>();
    props.put(ContentModel.PROP_NAME, doc.getPath());
    props.put(QName.createQName(EPIC_NAMESPACE_URI, "fileName"), "FILENAMEEEEEEE132423");
    NodeRef nodeRef = nodeService.createNode(root,
            ContentModel.ASSOC_CONTAINS,
            QName.createQName(NamespaceService.CONTENT_MODEL_1_0_URI, "myNameIsMehrdad"),
            type, props).getChildRef();

    ContentWriter contentWriter = contentService.getWriter(nodeRef, ContentModel.PROP_CONTENT, true);
    contentWriter.setMimetype(MimetypeMap.MIMETYPE_TEXT_PLAIN);
    contentWriter.setEncoding("UTF-8");
    contentWriter.putContent(new ByteArrayInputStream(doc.getBytes()));

    logger.info("EpicDocument created with NodeRef = {}", nodeRef.toString());
    return doc;
}

我得到以下错误信息。

是什么问题？我不知道，我是不是错过了什么？

更新：我是否需要调用 NodeService 方法（就像示例中的 此处)?!

问题解决了。

正如我所猜测的，问题与事务有关。我没有调用 upload() 在事务中调用方法。

现在，我在事务中调用方法，使用 RetryingTransactionHelper 得自 ServiceRegistry:

    NodeRef nodeRef = serviceRegistry.getRetryingTransactionHelper().doInTransaction(
            new RetryingTransactionHelper.RetryingTransactionCallback<NodeRef>() {
                public NodeRef execute() throws Throwable {

                //do work here...
}
}
);

注意：不要忘记为调用的线程创建安全上下文，方法是使用 AuthenticationService 's authenticate() 例如，方法。
