下面是 HugeGraph Java 客户端批量创建边（addEdges）的标准用法案例，结合了实际测试代码和官方示例：
1. **确保已定义好 VertexLabel 和 EdgeLabel**，如：
```java
schema.vertexLabel("person")
.properties("name", "age")
.primaryKeys("name")
.ifNotExist()
.create();
schema.vertexLabel("software")
.properties("name", "lang", "price")
.primaryKeys("name")
.ifNotExist()
.create();
schema.edgeLabel("created")
.link("person", "software")
.properties("date")
.ifNotExist()
.create();
```
2. **创建顶点对象并批量插入**（必须先插入顶点，边才能成功）：
```java
Vertex marko = new Vertex("person").property("name",
"marko").property("age", 29);
Vertex lop = new Vertex("software").property("name", "lop").property("lang",
"java").property("price", 328);
List<Vertex> vertices = Arrays.asList(marko, lop);
graph.addVertices(vertices);
```
3. **创建边对象并批量插入**：
```java
Edge markoCreateLop = new Edge("created")
.source(marko)
.target(lop)
.property("date", "2017-12-10");
List<Edge> edges = Arrays.asList(markoCreateLop);
graph.addEdges(edges);
```
4. **注意事项**：
- `Edge` 的 source/target 必须是已存在的 `Vertex` 对象。
- 必须先 addVertices，再 addEdges，否则会报错（如 InvalidOperationException）。
- `Edge` 构造时 label、source、target、属性都要明确指定，label 必须是 schema 里定义的
EdgeLabel，source/target 的类型必须和 EdgeLabel 的 sourceLabel/targetLabel 匹配。
- 支持批量插入 List<Edge>，也支持 List<Map<String, Object>>，但推荐用 Edge 对象，类型安全且易于维护。
完整示例可参考
[BatchExample.java](https://github.com/apache/incubator-hugegraph-toolchain/blob/9696d78e4d0b6e10d4e3382248fd8bda61295a91/hugegraph-client/src/main/java/org/apache/hugegraph/example/BatchExample.java)
和
[BatchInsertTest.java](https://github.com/apache/incubator-hugegraph-toolchain/blob/9696d78e4d0b6e10d4e3382248fd8bda61295a91/hugegraph-client/src/test/java/org/apache/hugegraph/functional/BatchInsertTest.java)。
如需更复杂的属性或批量数据，可以循环构造 Vertex 和 Edge 对象，最后分别调用 addVertices 和 addEdges 即可。
