我已将neo4j嵌入式版本1.9.8升级到2.3.8，后期升级服务器已启动。但是从下面的代码获取NotInTransactionException。索引似乎有些问题
protected Record getNext() throws Exception {
if (hits == null) {
hits = index.query(query);
}
T next = hits.next();
if (next == null) {
return finished();
} else {
return nodeToRecord.call(next);
}
}
以下是错误。我的班级名称是GraphNodeIterator
