Question

我实际上已经坚持了几个小时..

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

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]]

我知道签名方法与我的参数不符，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
在第578行：
public long createNode（Map properties，Label ... labels）

这正是我从我的groovy发出的。



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 - ＆gt;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batch变量。取代

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

带

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

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