Question

我有以下链接来做这个，但问题是它是针对Linux用户的！

http://blog.neo4j.org/2013/03/importing-data-into-neo4j-spreadsheet.html

请帮我在Windows上完成这项工作？提前谢谢。

我是neo4j的新手，并且只获得了一些关于java的经验。

我从以下链接

将neo4jtools添加到我的neo4j服务器

https://github.com/jexp/neo4j-shell-tools

然后我按照此命令将少量数据导入图形数据库

neo4jshell -path C:\Program Files\neo4j-community-2.0.0\data\test5.db -config C:\Program Files\neo4j-community-2.0.0\conf\neo4j.properties -file C:\Users\admin\Downloads\import.txt

我在命令提示符

上收到这样的消息

> Transaction started
> +-------------------+ | No data returned. |
> +-------------------+ Nodes created: 20 Properties set: 60 3586 ms Transaction committed Transaction started ERROR (-v for expanded
> information):

我的import.txt文件内容是这些

我可以看到很多东西都是在test5.db文件夹中创建的，

但是当我进入浏览器控制台时，我看不到任何节点？

还有什么可做的吗？我正确的方式？请帮我继续前进!!!

Answer 1

您的配置是什么样的？

您是否启用了自动索引功能：

# Autoindexing

# Enable auto-indexing for nodes, default is false
node_auto_indexing=true

# The node property keys to be auto-indexed, if enabled
node_keys_indexable=id,name,type

删除哈希并确保列出id属性。您可能也可能不会为索引查找添加name和type属性。

由于您创建了data/test5.db，因此您在浏览器中看不到任何内容，但默认情况下服务器正在查找data/graph.db。

所以要么使用这个目录。
或者启动服务器，然后取消-path参数，shell将连接到正在运行的服务器。

Answer 2

您的最终目标是导入工作表。请按照您提供的链接中给出的步骤将cypher查询放入文件中。然后使用java代码读取文件（BufferReader）并运行cypher查询使用ExecutionEngine。

复制查询时不要忘记放置任何能识别cypher查询开始和结束的分隔符。循环查询。

如果您要将其他来源的数据导入Neo4j，您可以使用Talend之类的ETL软件。这是一步一步的帖子，以简单的方式展示了如何： Import Data into Neo4j directly using Talend。它显示了如何从MS SQL Sever导入数据，但您可以轻松更改源
