我得到了下面的链接来做到这一点，但问题是它是为 linux 用户准备的！！！

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

请帮我在 Windows 上完成这项工作？提前致谢。

我是 neo4j 的新手，对 java 的经验只有一点点。

我从以下链接将 neo4jtools 添加到我的 neo4j 服务器

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

然后我按照这个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

我在命令提示符下收到这样的消息

> Transaction started
> +-------------------+ | No data returned. |
> +-------------------+ Nodes created: 20 Properties set: 60 3586 ms Transaction committed Transaction started ERROR (-v for expanded
> information):
>         MissingIndexException: Index `node_auto_index` does not exist

我的 import.txt 文件内容是这些

我可以看到在 test5.db 文件夹中创建了很多东西，

但是当我转到浏览器控制台时，我看不到那里的任何节点？

还有什么事情要做吗？走对了吗？请帮助我继续前进！

你的配置是什么样的？

您是否像这样启用了自动索引：

# 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id列出该属性。您可能会也可能不会为索引查找添加name和属性。type

此外，您在浏览器中看不到任何内容，因为您创建了data/test5.db但服务器默认查找data/graph.db.

  1. 所以要么使用这个目录。
  2. 或者启动服务器，然后去掉-path参数，shell 将连接到你正在运行的服务器。

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

复制查询时不要忘记放置任何分隔符，以识别密码查询的开始和结束。循环运行查询。

如果您希望将其他来源的数据导入 Neo4j，您可以使用 Talend 等 ETL 软件。下面是一步一步的帖子，以简单的方式展示了如何做到这一点： 直接使用 Talend 将数据导入 Neo4j。它显示了如何从 MS SQL Sever 导入数据，但您可以轻松更改源
