在com.mongodb.client.MongoDatabase.createCollection( mongoDB期间，是否可以在createCollection上创建索引

import com.mongodb.client.MongoClient;
import com.mongodb.client.MongoClients;
import com.mongodb.client.MongoDatabase;
import org.bson.Document;
import com.mongodb.client.model.Indexes;

public class CreateCollectionWithIndex {
    public static void main(String[] args) {
        // 创建MongoDB客户端
        MongoClient mongoClient = MongoClients.create("mongodb://localhost:27017");
        
        // 连接数据库
        MongoDatabase database = mongoClient.getDatabase("mydb");
        
        // 创建集合，并在创建过程中创建索引
        database.createCollection("mycollection", new Document()
                .append("validator", new Document()
                        .append("$and", new Document[]
                                {
                                        new Document("name", new Document("$type", "string")),
                                        new Document("age", new Document("$type", "int"))
                                }))
                .append("validationLevel", "strict")
                .append("validationAction", "error")
                .append("indexOptionDefaults", new Document()
                        .append("name", "myindex")
                        .append("key", Indexes.ascending("name", "age"))));
        
        // 关闭客户端连接
        mongoClient.close();
    }
}
