问题
I got the below link to do this but the problem is that it's for linux users !!!
http://blog.neo4j.org/2013/03/importing-data-into-neo4j-spreadsheet.html
Please help me to get this done on windows ? Thanks in advance.
I am new to neo4j and got only a little hands on experience on java.
I added neo4jtools to my neo4j server from the below link
https://github.com/jexp/neo4j-shell-tools
then I follow this command to import few data to a graph database
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
and I get a message like this on the command prompt
> 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
my import.txt file contents are these

And I can see lot of thing are created inside the test5.db folder,
but when I go to my browser console I cant see any nodes there ?
Is there anything more to do ? Am on the right way ? Please help me to move on !!!

回答1:
What does your config look like?
Do you have auto-indexing enabled like this:
# 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
Remove the hashes and make sure that the id property is listed. You might or might not add the name and type properties for index lookups as well.
Also you don't see anything in your browser because you created data/test5.db but the server is by default looking for data/graph.db.
- So either use this directory.
- Or start the server, and then leave off the
-pathparameter and the shell will connect to your running server.
回答2:
your final goal is to import the sheet.So follow the steps given in link provided by you and put the cypher queries in a file.Then use java code to read file(BufferReader) and run the cypher queries using ExecutionEngine.
While copying queries don't forget to put any separator which will recognize the start and end of cypher queries.Run queries in loop.

If you are looking to import data from other source into Neo4j, you can use ETL Software like Talend. Here is a step by step post shows how to that in a simple way: Import Data into Neo4j directly using Talend. It shows how to import data from MS SQL Sever but you can easily change the source
