如何用java从mongodb bson文档中获取整数值？

// Maven
<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongodb-driver-sync</artifactId>
    <version>4.4.3</version>
</dependency>

// Gradle
implementation 'org.mongodb:mongodb-driver-sync:4.4.3'

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

// 连接到MongoDB数据库
MongoClient mongoClient = MongoClients.create("mongodb://localhost:27017");

// 获取数据库对象
MongoDatabase database = mongoClient.getDatabase("your_database_name");

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

// 获取文档对象
Document document = collection.find().first();

// 从文档中获取整数值
int intValue = document.getInteger("your_field_name");
