Question

我正在尝试删除使用jackrabbit保存的节点，但我收到此错误。

Failed to  delete file
! javax.jcr.nodetype.ConstraintViolationException: Unable to perform operation. Node is protected.

以下是我用来保存它的代码：

            session = repository.login(new SimpleCredentials("admin", "admin".toCharArray()));

            Node parent = (Node) itemAtPath(parentPath, session);
            Node newNode = parent.addNode(nodeName);
            newNode.addMixin("mix:versionable");
            session.save(); // Create Root Node

            VersionableChanges changes = new VersionableChanges(newNode.getSession());
            changes.checkout(newNode);

            Binary binary = session.getValueFactory().createBinary(in);
            newNode.setProperty(PROPERTY_DATA, binary);
            newNode.setProperty(PROPERTY_NAME, fileName + System.currentTimeMillis());
            newNode.setProperty(PROPERTY_CREATEDBY, createdBy);
            newNode.setProperty(PROPERTY_CREATEDDATE, createdDate);
            newNode.setProperty(PROPERTY_COMMENT, comment);
            Value value = session.getValueFactory().createValue(binary);
            changes.checkin();
            session.save();

以下是我用来删除它的代码：

            session = repository.login(new SimpleCredentials("admin", "admin".toCharArray()));
            Version fileVersion = null;
            Node fileNode = null;

            if (version != null && !version.isEmpty()) {
                fileVersion = session.getWorkspace().getVersionManager().getVersionHistory(path).getVersion(version);
            } else {
                fileVersion = session.getWorkspace().getVersionManager().getBaseVersion(path);
            }

            fileNode = fileVersion.getFrozenNode();
            fileNode.remove();
            //need to save session to persist the remove operation
            session.save();

如何克服此错误？

冻结节点受到保护，因为删除它们（可能）会使版本存储处于损坏状态。为了删除＆＃34;完成＆＃34;从历史版本来看，你必须这样：

VersionHistory history = session.getWorkspace().getVersionManager()
                            .getVersionHistory(info.getVersionedNodePath());
history.removeVersion(info.getVersionName());
session.save();

无法删除jackrabbit中的节点
