Question

请让我知道我哪里出错了我正在使用neo4j来存储我的路由器接口和链接信息。该链接将在2个接口之间创建。我已成功创建节点和接口，但在创建链接时遇到了问题。

这是我用来创建链接的查询

MATCH (I:Interface), (I2:Interface) 
FOREACH(p in FILTER(z in {props} WHERE z.OrigIPAddress = I.IfIPAddress or z.TermIPAddress = I.IfIPAddress) | 
MERGE (I {IfIPAddress:p.OrigIPAddress})-[r:link]->(I2 {IfIPAddress:p.TermIPAddress}) 
ON CREATE SET r = p 
ON MATCH SET r = p)

我有一个名为props的地图数组，我在json中传递为包含链接属性的params，即OrigIPAddress（Originating interface IP），TermIPAddress（Terminating interface ip）。在foreach中，我首先过滤所有已经存在源或目标接口的链接。现在我这样做后，我正在创建道具链接。

当我运行它时它运行正常但没有创建链接。存在源和目标接口。

编辑1：我修改了查询，当我运行此查询时

MATCH (I:Interface), (I2:Interface) 
FOREACH(p in FILTER(z in {props} WHERE z.OrigIPAddress = I.IfIPAddress and z.TermIPAddress = I2.IfIPAddress) | 
MERGE (I {IfIPAddress:p.OrigIPAddress})-[r:link]->(I {IfIPAddress:p.TermIPAddress}) 
ON CREATE SET r = p 
ON MATCH SET r = p)

我没有从neo4j和neo4j web控制台得到ant响应我可以看到这个meesage “Neo4j断开了，检查你的插座......”

让我知道我在哪里出错。

Answer 1

这更接近你想要做的事情吗？

MATCH (I:Interface)
FOREACH(
  p in FILTER(z in {props}
    WHERE z.OrigIPAddress = I.IfIPAddress or z.TermIPAddress = I.IfIPAddress) | 
  MERGE (I)-[r:link]->(:Interface {IfIPAddress:p.TermIPAddress})
  SET I.IfIPAddress = p.OrigIPAddress, r = p
);

Answer 2

最后在谷歌搜索后我发现了这个问题。它的服务器超时。由于查询需要一些时间来执行，因此服务器会超时并发送响应。

我增加了超时并且它有效以下是如何增加它的参考。 http://docs.neo4j.org/chunked/stable/server-configuration.html

neo4j创建多个节点json
