以上是路径问题的常见错误提示,解决参考:
1. 将BussinessObj.csv放入配置文件neo4j.conf中dbms.directories.import这个配置项对应的目录下,
必须在路径上加上file:/或者file:// 这个非常重要:
如果是liunx系统必须加入file:/作为前缀,
windows系统加入LOAD CSV FROM "file://c:/location/local/my.csv"
以下是一个liunx示范:
比如配置项dbms.directories.import=/var/lib/neo4j/import, 要导入的文件BussinessObj.csv放入/var/lib/neo4j/import目录下,然后按如下方式导入:
1. 打开 浏览器,输入http://IP:7474/browser/,输入以下命令执行导入即可,注意路径是file:/你的文件名,路径中不要包含dbms.directories.import的配置路径/var/lib/neo4j/import
LOAD CSV WITH HEADERS FROM "file:/BussinessObj.csv" AS line
MERGE (b:BussinessObj{name:line.name,coreFlag:line.coreFlag,description:line.description})
