我按照步驟maxdemarzi。我接受了這個example的csv數據。 但是,執行此命令時發生此錯誤。如何將csv文件導入到neo4j中NumberFormatException

java -server -Dfile.encoding=UTF-8 -Xmx4G -jar batch-import-jar-with-dependencies.jar neo4j/data/graph.db BeerNodes.csv BeerRelationships.csv 

Usage: Importer data/dir nodes.csv relationships.csv [node_index node-index-name 
fulltext|exact nodes_index.csv rel_index rel-index-name fulltext|exact rels_ind 
ex.csv ....] 
Using: Importer neo4j/data/graph.db BeerNodes.csv BeerRelationships.csv 

Using Existing Configuration File 

Importing 2351 Nodes took 0 seconds 

Total import time: 2 seconds 
Exception in thread "main" java.lang.NumberFormatException: For input string: "1 
,10000,isa" 
     at java.lang.NumberFormatException.forInputString(Unknown Source) 
     at java.lang.Long.parseLong(Unknown Source)

     at org.neo4j.batchimport.Importer.id(Importer.java:163)

     at org.neo4j.batchimport.Importer.doImport(Importer.java:214) 
     at org.neo4j.batchimport.Importer.main(Importer.java:78) 

有什麼建議嗎?

將您的csv文件轉換爲使用TAB作爲字段分隔符。
