neo4j之'neo4j-import(neo4j-admin import)实战'

1.neo4j-admin import语法:

neo4j-admin import [--mode=csv] [--database=<name>]
                          [--additional-config=<config-file-path>]
                          [--report-file=<filename>]
                          [--nodes[:Label1:Label2]=<"file1,file2,...">]
                          [--relationships[:RELATIONSHIP_TYPE]=<"file1,file2,...">]
                          [--id-type=<STRING|INTEGER|ACTUAL>]
                          [--input-encoding=<character-set>]
                          [--ignore-extra-columns[=<true|false>]]

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:
