如何在CosmosDB中将树格式的Gremlin GraphSON转换为自定义的JSON树格式？

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;

import org.apache.tinkerpop.gremlin.driver.Cluster;
import org.apache.tinkerpop.gremlin.driver.Result;
import org.apache.tinkerpop.gremlin.driver.ResultSet;

import java.util.concurrent.CompletableFuture;

    public static void main(String[] args) {
        Cluster cluster = Cluster.build(ENDPOINT)
                .port(443)
                .enableSsl(true)
                .credentials(DATABASE, MASTER_KEY)
                .create();

        Client client = cluster.connect();

        String gremlinQuery = "g.V().hasLabel('your_label').valueMap()";
        CompletableFuture<ResultSet> future = client.submitAsync(gremlinQuery);

        future.thenApply(ResultSet::all)
                .thenAccept(results -> {
                    for (Result result : results) {

        cluster.close();
    }

    private static JsonNode convertToCustomJsonTree(JsonNode graphsonNode) {
        // TODO: Implement the conversion logic based on your custom JSON tree format
        // You can use libraries like Jackson to manipulate JSON data

        // Example conversion: graphsonNode -> customJsonTree
        ObjectMapper mapper = new ObjectMapper();
        JsonNode customJsonTree = mapper.createObjectNode();
        ((ObjectNode) customJsonTree).put("id", graphsonNode.get("id").asText());
        ((ObjectNode) customJsonTree).put("name", graphsonNode.get("name").asText());

        return customJsonTree;
    }
}
