如何將csv文件導入neo4j NumberFormatException

Question

我遵循maxdemarzi的步驟。 我拿了這個例子的csv數據。 但是，執行此命令時發生了此錯誤。

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

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

有什么建議么？

Answer 1

轉換您的csv文件以使用TAB作為字段分隔符。

Answer 2

請執行Stefan所說的，或者：

使用逗號作為分隔符配置導入batch_import.csv.delim=,在batch.properties中使用： batch_import.csv.delim=, 。
