Question

我对orientDB很新，所以我可能做了一些非常错误的事情，仍然在这里：

OrientGraphFactory factory = new OrientGraphFactory("remote:localhost/testdb","root","12345").setupPool(2, 10);;

我创建了一些VertexTypes和EdgeTypes：

OrientGraphNoTx graph = factory.getNoTx();
graph.createVertexType("Company");
graph.createVertexType("Contract");
graph.createEdgeType("SignedWith");

还创建了一些索引：

graph.createKeyIndex("itemid", Vertex.class, new Parameter<>("class", "Contract" ));
graph.createKeyIndex("itemid", Vertex.class, new Parameter<>("class", "Company"));

现在在创建时我会执行以下操作：

OrientGraph graph = factory.getTx();

Vertex contract = graph.addVertex("class:Contract");
contract.setProperty("itemid", field.longValue());
[... many other properties]

Vertex company = graph.addVertex("class:Company");
company.setProperty("itemid", field.longValue());
[... many other properties]

contract.addEdge("SignedWith", company);
// Also tried this way:
//graph.addEdge(null, contract, company ,"SignedWith" );

每次我一直得到：

[debug] c.j.n.n.OrientDBUtils - verify contract has id : #16:-2
[debug] c.j.n.n.OrientDBUtils - verify company has id : #12:-2
[error] c.j.n.c.OrientDBIndexerRunnable - NeoIndexerRunnable - indexing problem Contract Id:20

我错过了什么吗？

在Linux上运行orientDB 2.0-M3。

非常感谢你的帮助

当事务在创建Vertexes之间回滚时会发生这种情况。

当一个事务不可用或被回滚时，我期望在使用OrientGraph对象创建Vertex时看到更明确的异常。它实际上会自动创建一个新的交易。
