搜索在Janusgraph中的属性赋值的原始数据数组的成员

graph.addVertex(T.id, "v1").property("name", "Alice");

Vertex vertex = graph.traversal().V("v1").next();
List<String> friends = vertex.value("friends");
String firstFriend = friends.get(0); // 获取第一个朋友

    public static void main(String[] args) {
        // 打开图数据库
        JanusGraph graph = JanusGraphFactory.open("conf/janusgraph-berkeleyje-es.properties");

        // 添加一个顶点并设置属性
        Vertex v1 = graph.addVertex(T.id, "v1");
        v1.property("name", "Alice");
