如何将聚合管道中的文档与MongoDB Java driver 3.6结合起来？

import com.mongodb.MongoClient;
import com.mongodb.MongoClientURI;
import com.mongodb.client.MongoDatabase;

// 创建MongoClient实例
MongoClientURI uri = new MongoClientURI("mongodb://localhost:27017");
MongoClient mongoClient = new MongoClient(uri);

// 连接到数据库
MongoDatabase database = mongoClient.getDatabase("your_database_name");

import com.mongodb.client.model.Aggregates;
import org.bson.conversions.Bson;

// 创建聚合管道
List<Bson> pipeline = Arrays.asList(
    Aggregates.match(Filters.eq("field", "value")),
    Aggregates.group("$field", Accumulators.sum("total", "$amount"))
);

import com.mongodb.client.MongoCollection;
import org.bson.Document;

// 获取集合
MongoCollection<Document> collection = database.getCollection("your_collection_name");

// 执行聚合操作
List<Document> result = collection.aggregate(pipeline).into(new ArrayList<>());

// 处理结果
for (Document document : result) {
    // 处理每个文档
}
