无法使用 Alfresco public Java API 创建节点，拒绝访问。系统当前处于只读模式
can not create node with Alfresco public Java API, Access Denied. The system is currently in read-only mode
我正在为 Alfresco 内容服务社区版 6.2.0-ga 版开发一个模块，我无法通过 NodeService 创建节点，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;
}
我收到以下错误：
Caused by: org.alfresco.service.transaction.ReadOnlyServerException: 04100056 Access Denied. The system is currently in read-only mode.

有什么问题？我不知道，我错过了什么吗？
更新：我是否需要在交易中调用 NodeService 方法（如示例 here）？！
问题已解决。
如我所料，问题与交易有关。我没有在交易中调用 upload()。
现在，我使用从 ServiceRegistry:
获得的 RetryingTransactionHelper 在交易中调用方法
NodeRef nodeRef = serviceRegistry.getRetryingTransactionHelper().doInTransaction(
new RetryingTransactionHelper.RetryingTransactionCallback<NodeRef>() {
public NodeRef execute() throws Throwable {
//do work here...
}
}
);
注意：不要忘记使用 AuthenticationService 的 authenticate() 方法为调用线程创建安全上下文。
