如何用Java在MongoDB 3.3中用_id删除文档

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

public class DeleteDocumentExample {
    public static void main(String[] args) {
        // 连接到MongoDB数据库
        MongoClient mongoClient = new MongoClient("localhost", 27017);
        // 选择数据库
        MongoDatabase database = mongoClient.getDatabase("mydb");
        // 选择集合
        MongoCollection<Document> collection = database.getCollection("mycollection");

        // 创建一个查询条件，这里使用_id字段
        ObjectId id = new ObjectId("609d7f7b8b8a9f2f5c6d7e8f");
        Document query = new Document("_id", id);

        // 删除文档
        collection.deleteOne(query);

        // 关闭连接
        mongoClient.close();
    }
}
