2.实战

1).创建三个表:
movies.csv

movie:ID,name,:LABEL
tt0133093,The Matrix,movie
tt0234215,The Matrix Reloaded,movie
tt0242653,The Matrix Revolutions,movie

actors.csv

person:ID,name,:LABEL
keanu,Keanu Reeves,person
laurence,Laurence Fishburne,person
carrieanne,Carrie-Anne Moss,person

roles.csv

:START_ID,role,:END_ID
keanu,Neo,tt0133093
keanu,Neo,tt0234215
keanu,Neo,tt0242653
laurence,Morpheus,tt0133093
laurence,Morpheus,tt0234215
laurence,Morpheus,tt0242653
carrieanne,Trinity,tt0133093

2)将三个表放入 neo4j-community-3.5.0\import文件夹中

3)cmd环境下进入 neo4j-community-3.5.0

  如图:

4)输入如下指令:

.\bin\neo4j-import --into data\databases\graph.db --nodes .\import\practice\actors.csv --nodes .\import\practice\movies.csv --relationships:ACTED_IN .\import\practice\roles.csv --skip-duplicate-nodes=true --skip-bad-relationships=true --stacktrace --bad-tolerance=500000

 或:

.\bin\neo4j-admin import --database=graph.db --nodes .\import\practice\actors.csv --nodes .\import\practice\movies.csv --relationships:ACTED_IN .\import\practice\roles.csv 

 官方建议使用  neo4j-admin import

  如图: 

5)启动neo4j
