无法使用MongoDB Java通过lastprocessedTime进行查询

import com.mongodb.client.MongoClients;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoCursor;
import com.mongodb.client.MongoDatabase;
import com.mongodb.client.model.Filters;
import org.bson.Document;

import java.util.Date;

public class MongoDBJavaExample {
    public static void main(String[] args) {
        // 连接到MongoDB数据库
        try (var client = MongoClients.create("mongodb://localhost:27017")) {
            // 选择数据库和集合
            MongoDatabase database = client.getDatabase("mydb");
            MongoCollection<Document> collection = database.getCollection("mycollection");

            // 创建查询条件
            Document query = new Document("lastprocessedTime", new Document("$gt", new Date()));

            // 执行查询
            MongoCursor<Document> cursor = collection.find(query).iterator();

            // 处理查询结果
            while (cursor.hasNext()) {
                Document result = cursor.next();
                // 处理每条结果的逻辑
                System.out.println(result.toJson());
            }
        }
    }
}
