<!-- Answer --> 你的 struct.json 和 schema.groovy 配置思路是对的，但要确保所有连接关系都能导入，必须做到以下几点： 1. edge_connected_to.csv 必须有 source_label 和 target_label 两列，并且内容要和 schema.groovy 里顶点的 label 完全一致（比如 LineSegment、StationHouse、LineSwitch、Substation 等），否则边会被跳过但不会报错（[官方文档说明](https://github.com/apache/incubator-hugegraph-doc/blob/3e1c610281c91ea3a5c600b393088e9ffae34799/content/en/docs/quickstart/toolchain/hugegraph-loader.md#L139-L1100)）。 2. struct.json 里每个 edgeLabel（比如 Substation2LineSegment、LineSegment2StationHouse、LineSegment2LineSegment、LineSegment2LineSwitch、LineSwitch2LineSegment、StationHouse2LineSwitch、LineSwitch2StationHouse 等）都要写一段，value_mapping 里的 label/source_label/target_label 必须和 schema.groovy 里的 edgeLabel、sourceLabel、targetLabel 完全一致。 3. 你的 edge_connected_to.csv 目前只有 from、to、label，没有 source_label/target_label，建议用脚本或 Excel 增加这两列，内容要和 from/to 对应的顶点类型一致（比如 from=XLD-3445 就查 vertex_linesegment-1.csv，类型是 LineSegment）。 4. 只有这样，struct.json 的 value_mapping 才能精确筛选属于自己的那部分边，否则 loader 会尝试导入所有行，但只有 label、source_label、target_label 都匹配 schema 才会真正导入，其他会被静默跳过。 5. 导入后建议用 REST API 查询各类边的数量和类型，确认所有关系都齐全。 举例（以 LineSegment2StationHouse 为例）： ```json { "label": "LineSegment2StationHouse", "source": ["from"], "target": ["to"], "input": { "type": "file", "path": "/loader/power_data/edge_connected_to.csv", "format": "CSV", "header": ["id", "from", "to", "label", "source_label", "target_label"] }, "field_mapping": { "from": "id", "to": "id" }, "value_mapping": { "label": { "CONNECTED_TO": "LineSegment2StationHouse" }, "source_label": { "LineSegment": "LineSegment" }, "target_label": { "StationHouse": "StationHouse" } } } ``` 每种类型的边都要写一段，path 可以都指向同一个 CSV 文件。 **建议你先检查 edge_connected_to.csv 是否有 source_label/target_label 字段，且内容和顶点 label 一致，再检查 struct.json 里每个 edgeLabel 的 value_mapping 是否和 schema.groovy 完全一致。** 如还有问题，可以贴出一小段 edge_connected_to.csv（含 source_label/target_label）和 struct.json 的完整 edge 配置，我可以帮你逐条检查。 <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
