MissingMethodException - org.neo4j.kernel.impl.coreapi.schema.IndexDefinitionImpl.createNode() - Groovy

Question

我实际上被困了几个小时..

我的代码很简单，只想使用标签索引添加几个节点。 没有索引的东西（不要创建 createDeferredSchemaIndex ）代码可以正常工作。

我的例外是：

groovy.lang.MissingMethodException: No signature of method: org.neo4j.kernel.impl.coreapi.schema.IndexDefinitionImpl.createNode() is applicable for argument types: (java.util.LinkedHashMap, [Lorg.neo4j.graphdb.Label;) values: [[tag:START], [MacMorphoTag]]

我知道与我的参数不匹配的签名方法，但是通过这里的 Neo4J 代码：https://github.com/neo4j/neo4j/blob/master/community/kernel/src/main/java/org/neo4j/unsafe/batchinsert/BatchInserterImpl.java
在线 578:
public long createNode(地图属性，标签...标签)

这正是我从我的 groovy 中发送的。

batch = org.neo4j.unsafe.batchinsert.BatchInserters.inserter(store,config)
batch = batch.createDeferredSchemaIndex( macMorphoTagLabel ).on( 'tag' ).create();
...

Label macMorphoTagLabel = DynamicLabel.label( 'MacMorphoTag' );

def Label[] macMorphoTagArray = [macMorphoTagLabel]
if (!tags[previousWordTag.macMorphoTag]) {
                        tags[previousWordTag.macMorphoTag] = batch.createNode([tag: previousWordTag.macMorphoTag], macMorphoTagArray)
                    }

我在这里错过了什么？我正在使用 Groovy 2.3.7 + Neo4j 2.1.5

例如 -> 我的完整代码：http://pastebin.com/Z98tMDYi 问题发生在第 110 行
我的 Json 文件是：http://pastebin.com/xSxZd4ke（作为 UTF-8 文件）

Answer 1

在第 66 行，您重新分配了 batch 变量。替换

batch = batch.createDeferredSchemaIndex( macMorphoTagLabel ).on( 'tag' ).create();

与

batch.createDeferredSchemaIndex( macMorphoTagLabel ).on( 'tag' ).create();
