如何更改 Neo4j Java 驱动程序的配置属性？

Question

I am doing a homework assigment about Neo4j. I am using Neo4j Java driver library with Scala. I made a query to load data from CSV but error appears:

configuration property 'dbms.security.allow_csv_import_from_file_urls' is false
    at org.neo4j.driver.internal.util.Futures.blockingGet(Futures.java:111)

Is there a way to change this property in IntelliJ? Thank you!

I tries to google the problem, but it didn't found any answers.

This property is not managed by Neo4j Java Driver, it is managed by Neo4j server.

It is documented here: https://neo4j.com/docs/operations-manual/current/reference/configuration-settings/

Depending on how Neo4j server is deployed, there are multiple ways of updating it. For instance:

1. Binary: add dbms.security.allow_csv_import_from_file_urls=true to <neo4j-home>/conf/neo4j.conf OR ensure it is not set there as it should be true by default
2. Docker: set environment variable NEO4J_dbms_security_allow__csv__import__from__file__urls=true (more details here: https://neo4j.com/docs/operations-manual/current/docker/configuration/ )
3. Neo4j Desktop: edit settings of the target DBMS
4. Neo4j Aura: CSV file should be loaded as a remote file. This error can be reproduced when query references a local file. See the documentation for more details: https://neo4j.com/docs/aura/auradb/importing/importing-data/
