apoc导出数据

导出前的apoc.conf配置

# 允许APOC读写磁盘文件
apoc.export.file.enabled=true
apoc.import.file.enabled=true
# 放开所有apoc存储过程权限（可选，防止权限报错）
dbms.security.procedures.unrestricted=apoc.*

创建或者修改conf后要重启数据库

导出命令：

不带上id

CALL apoc.export.cypher.all("full_graph_dump.cypher", { format: "cypher-shell", useTypes: true, exportConstraints: true, exportIndexes: true }) YIELD file, nodes, relationships RETURN file, nodes, relationships;

命令会导出到import文件夹，文件名是full_graph_dump.cypher

带上id

CALL apoc.export.cypher.all("full_graph_dump_with_ids.cypher", {
    format: "cypher-shell",
    useTypes: true,
    exportConstraints: true,
    exportIndexes: true,
    writeNodeIds: true,      // ✅ 输出 node id
    writeRelationshipIds: true // ✅ 输出 rel id
}) YIELD file, nodes, relationships 
RETURN file, nodes, relationships;

目标库必须清空：MATCH (n) DETACH DELETE n;

windows cmd 导入数据命令

cypher-shell -a neo4j://localhost:7687 -u neo4j -p "12345678" -f "F:\app\neo4j-community-5.26.13\import\full_graph_dump_with_ids20260903.cypher"
